Hatiora - Hatiora × graeseri[edit]
Hi,
You are recategorizing some photos. Those Hatiora could be Hatiora × graeseri? Regards. DenesFeri (talk) 11:05, 7 November 2011 (UTC)
- Yes, I think that they almost certainly are. I was mainly interested in getting them out of Schlumbergera! If you want to put them in Hatiora × graeseri I would support you. Peter coxhead (talk) 11:08, 7 November 2011 (UTC)
OK, Thanks! I will rename them too. DenesFeri (talk) 11:16, 7 November 2011 (UTC)
beautiful photograph[edit]
thanks for posting and sharing it. Susan Dunlap (talk) 22:34, 8 December 2013 (UTC)
- Thanks are always appreciated, although you don't say which photo! Peter coxhead (talk) 13:51, 9 December 2013 (UTC)
misidentified photo - how do I flag?[edit]
Hi Peter, just came across this photo purporting to be Silene acaulis. Looks like a Primula (glutinosa?) to me. How do I flag this>
Thanks Tristan--Tristan He (talk) 20:55, 10 September 2015 (UTC)
@Tristan He: I agree with you that it's not Silene acaulis, and looks to be a Primula. The photographer was fooled, I suspect, by the way it's growing though other plants. What you are supposed to do "officially", I'm not sure. I'm not really active on Commons. In the past when I've found mis-identified photos, I've just been bold and (a) changed the category to the correct one (b) added a note to the description. No-one seems to read the talk pages on Commons, so starting a discussion there doesn't work, in my experience. Peter coxhead (talk) 09:14, 14 September 2015 (UTC)
Araneus quadratus[edit]
Thanks for this. --DPC (talk) 18:11, 22 April 2016 (UTC)
- And, is this A. quadratus too? --DPC (talk) 18:15, 22 April 2016 (UTC)
- Well, all the experts say that you shouldn't rely on patterns, but look at the genitalia of mature specimens, but this isn't much use here. In my geographically limited experience, the background colour is very variable, so not significant. Both species can look as if they have a cross shape on the abdomen, but when A quadratus looks to have a cross pattern, the central line is interrupted or weak, and the second pair of spots larger than the first. The central part of the pattern (folium) is notably darker than the surrounding colour in A. diadematus but much the same colour in A. quadratus. The angle in the queried photo gives a limited view, but I think "01_by-dpc" and "02_by-dpc" are the same. Peter coxhead (talk) 20:03, 24 April 2016 (UTC)
Hi Peter, please don't redirect to not (yet) existing categories because these redirects apppear to be broken and thus might be deleted without further notice. Thank you. --Achim (talk) 15:25, 22 October 2017 (UTC)
- Sorry, this was an error — when I redirected, I thought there was an image which belonged at the target category, but it turned out that there wasn’t and I forgot to go back and sort it out. Peter coxhead (talk) 21:06, 22 October 2017 (UTC)
Euphorbia lamarckii[edit]
I determined it as E. obtusifolia by Peter and Ingrid Schönefelder: Die Kosmos Kanarenflora, Kosmos-Verlag Germany, and according to that book this plant occurs on all Canary Islands,inclusive Fuerteventura. See also here, here, it is also listed in Gelandeliste zur Erfassung der Flora von Fuerteventura as well as in Gefährdete endemische Blütenpflanzen der Trockeninsel Fuerteventura. As E. obtusifolia is a synonym of E. lamarckii (it means the same species) and E. lamarckii is the valid name (not E. obtusifolia), this species occurs in Fuerteventura very well. So please remove back the pictures to the category "Euphorbia lamarckii". --Llez (talk) 17:21, 27 January 2018 (UTC)
- It's not so simple. The problem is that names have been changed. Some species have been split up. The most "scientific" of the online sources you give is the 2013 Gefährdete endemische Blütenpflanzen der Trockeninsel Fuerteventura. Besides just the name E. obtusifolia, this also mentions E. obtusifolia subsp. regis-jubae. If you look here, you will see that Euphorbia obtusifolia subsp. regis-jubae and Euphorbia lamarckii subsp. regis-jubae are both synonyms of E. regis-jubae, which does occur in Fuerteventura. I think that the sources that list E. obtusifolia and/or E. lamarckii as occurring in Fuerteventura are referring to subsp. regis-jubae, now known as E. regis-jubae. Look at the images in Category:Euphorbia regis-jubae. This is what I think your plants probably are. Peter coxhead (talk) 18:09, 27 January 2018 (UTC)
- The specialist website for Euphorbia agrees that E. lamarckii is not found in Fuerteventura – see here. This paper explains the controversy over some Euphorbia names, confirming that as the name is used now, E. lamarckii does not occur in Fuerteventura. Peter coxhead (talk) 09:32, 28 January 2018 (UTC)
- @Llez: see also here for a clear explanation of the issues if you can read Spanish. Peter coxhead (talk) 19:59, 28 January 2018 (UTC)

Google Code-In 2019 is coming - please mentor some documentation tasks![edit]
Hello,
Google Code-In, Google-organized contest in which the Wikimedia Foundation participates, starts in a few weeks. This contest is about taking high school students into the world of opensource. I'm sending you this message because you recently edited a documentation page at Wikimedia Commons.
I would like to ask you to take part in Google Code-In as a mentor. That would mean to prepare at least one task (it can be documentation related, or something else - the other categories are Code, Design, Quality Assurance and Outreach) for the participants, and help the student to complete it. Please sign up at the contest page and send us your Google account address to google-code-in-admins@lists.wikimedia.org, so we can invite you in!
From my own experience, Google Code-In can be fun, you can make several new friends, attract new people to your wiki and make them part of your community.
If you have any questions, please let us know at google-code-in-admins@lists.wikimedia.org.
Thank you!

EazyDraw[edit]
Hi Peter, thank you for your diagrams. As you can see et e.g. Historically recognized plant categories.svg something had been done to establish the {{Created with EazyDraw}}.
You say that a tool did not find W3C-errors? The validator finds a lot, because of the many formally wrong IDs created by EasyDraw. Never mind, that does not reduce the quality of your drawings! It would be "eazy" to remove all the unused IDs, making your drawings W3C-valid; but the mere W3C-validity is not such an important matter, that it will be worth the effort to change uploaded files – it might just be a possibility before uploading. Anyway, you shouldn't tag W3C-invalid files as valid. Good further success! -- sarang♥사랑 13:45, 5 September 2020 (UTC)
- @Sarang: I am confident that I did check the file before adding the "valid" template. There is something odd about the validator. I prepared a new SVG file from the same EazyDraw source file, as there's a new version of EazyDraw now. I checked this file on the validator website by browsing and uploading from my computer. The file was declared fully valid. I then uploaded it to Commons as a newer version. The validator then claims there are 24 errors. So either there's a bug in the validator or the upload mechanism introduces errors.
- I've put the file before uploading at
http://www.pxc.me.uk/misc/Historically%20recognized%20plant%20categories.svg; you can check that this is valid. Peter coxhead (talk) 08:35, 15 September 2020 (UTC)- Hi Peter, we are using at least three validators, and they have often different error counts - some ignore minor "violations" of the SVG syntax rules. The script uses another background validator than the two which I am using online. The fourth one is the Commons:Commons SVG Checker, with other results. In the case of Historically recognized plant categories.svg, all of them, even the Nu Validatot, are consistent with 24 times "Bad value ... for attribute id... Not a valid XML 1.0 name". But as said before, you should not take that too serious, that EazyDraw likes such IDs which are unfortunately not in the mind of our validators. -- sarang♥사랑 11:31, 15 September 2020 (UTC)
@Sarang: what you say is only true for the uploaded file in Commons. If I go to Commons:Commons SVG Checker and use the "Browse" button to check the the SVG file on my computer that I uploaded, it does not report the 24 errors. I do not understand why the checkers say that the file on my computer and the file I copied to [removed] are ok, whereas they say that the file in Commons is not. This still bothers me, since the time to check for SVG errors is before uploading, not afterwards. I would like to understand why this is the case. Peter coxhead (talk) 09:28, 17 September 2020 (UTC)

- It is a matter of fact that the different validators have different tolerance of syntactical rule violations, and that the Commons:Commons SVG Checker checks other things - not the syntax. In this problem, we have to chose on of them, and that is AFAIK the W3C-nu-validator used by the script.
- When another validator says that there are zero errors, that is not true because EazyDraw does not obey to the rules for building IDs (starting with a letter, consisting only of letters, numbers and understrokes). When there is no option for Eazydraw about the IDs, you may write a small programm or just edit afterwards the source code, either removing all the useless IDs or adding a leading letter. If there are no other inconveniencies, the SVG source will then be fine.
- As I said, you should not care for the error count as long as the image shows what you want. On the other hand, I can understand that you liked more to upload valid SVG. That will need more effort: you will have to clean the EazyDraw-output prior to upload. -- sarang♥사랑 10:58, 17 September 2020 (UTC)

There are 29 IDs with 14 occurrencies of erroneous writing.
When all the 29 IDs are removed the SVG will be valid. A small program can do it eazily.
As all tools, EazyDraw generates a lot of useless code which can be removed without any change.
Another possibility is to just make the 14 IDs valid, as I did by prefixing them with the letter "A":

When the error tag really disturbs you so much, write a small procedure which can reduce the SVG code to 20% or 10% of its current size, and makes it valid.
But do not change the drawings that are successfully uploaded to commons - just alter future files. -- sarang♥사랑 13:53, 17 September 2020 (UTC)
When you do not want to edit this sources by hand, or to create kind of a program, there are existing tools for that purpose: SVGcleaner can change the wrong IDs, and clean much more. Also exists a tool Scour that can clean SVG source code. These tools had been developed because other tools (not only EazyDraw!) are making a lot of nonsense. You will find these tools in the internet. -- sarang♥사랑 18:51, 17 September 2020 (UTC)
- @Sarang: thanks for the information and the time you have spent. Actually, I've discovered that EazyDraw does have an option not to output DOM IDs when exporting to SVG. The files produced in this way by the latest version of EazyDraw appear to be compliant. I won't bother to upload revised versions, as you suggest, but will try to ensure that in future SVG files I upload are compliant. (In the past I taught software engineering to undergraduates, and have been a member of national standards subcommittees, so I'm a strong believer in following standards.) Peter coxhead (talk) 18:59, 18 September 2020 (UTC)
To give you an example, I uploaded the cleaned version Microphyll evolution cleaned.svg which is now containing the code

As you can see, it is much smaller (54%) and does not contain W3C-errors, all the redundant IDs have been removed.
Still it contains a lot of nonsense, that the cleaner did not clean away!
It is unnecessary and pure bloating the file to define coordinates in that simple diagram with 8 decimal fractions - it would be sufficient to define coordinates in integers, without any fractional part. AFAIK it is an option of the tool Scour to round such values to less or no fractions; after such rounding the image may look slightly different, but at such a simple diagram that would not matter.
To perform that test, I downloaded the SVGcleaner from the internet, it is easy to handle; with Scour I have no experience, but it is used often by other users. I recommend that you clean the EazyDraw-output of your future files. -- sarang♥사랑 09:31, 19 September 2020 (UTC)
If I may summarize finally:
- W3C-errors are not bad, in most cases they are just minor formal unpleasantnesses against W3C- and HTML-rules.
- They will not reduce the display appearance and the quality of an image.
- If there is any fault, it is not yours, it is the behavior of the used tool.
- It will be of no use for wikipedia to make such files valid by uploading another version.
- (but when it is of use for you, when you feel better with valid SVGs, you may invest the effort)
- Of course valid new uploads are nicer than invalid ones. Cleaning tools (SVGcleaner,
ScourSVGomg and others) can help.
Good further success! -- sarang♥사랑 10:25, 19 September 2020 (UTC)
Now I got it[edit]
I could make a treating of the Microphyll evolution cleaned.svg with the tool https://jakearchibald.github.io/svgomg/ and got a file of 2922 bytes; I can really recommend that tool!
The output code from that tool is now

When you compare this W3C-valid code against the EazyDraw output (8617 bytes), you see the advantage of that tool. -- sarang♥사랑 17:03, 24 September 2020 (UTC)
Now the version from the SVGOMG cleaner[edit]
Hi Peter, I told you about another cleaner, and now I could test it. It is easy to use, when you are able to set its many parameters. When the code was cleaned I could see that Eazydraw made not only the embedded text (near the end of the code) but also the same text converted to path (near the top of the code) - removed the redundant path text of more than 1500 bytes (all between <font and </font>). The SVG code of Microphyll evolution omygod.svg looks now as it should be:

I made some of the disgarbaging "by hand" but the most of it is done by the tool. I can really recommend it for your future work! -- sarang♥사랑 12:30, 25 September 2020 (UTC)
Wisteria sinensis anatomia rev en.svg[edit]
If someone could brighten the colours of this illustration it could be much better. It is so dark that I cannot easily see the different parts. I don't have the software to do it. JMK (talk) 21:20, 17 April 2023 (UTC)
- @JMK: I agree that it's too dark. As it's an SVG drawing, it's not as easy to fix as an image would be; each section needs its colour changed. I think that File:Wisteria sinensis nobackground labels.jpg might be better. Peter coxhead (talk) 19:57, 18 April 2023 (UTC)
