Summary
[edit]_(27537237370).jpg&action=edit§ion=1){kind=link}
| Description | The population variation of Stipa neomexicana and Stipa comata at this site suggests that the distinguishing features of these species, and perhaps all Hesperostipa species, could represent population variation in open arid vegetation of southwestern USA. Stipa neomexicana is distinguished by lemma awns pilose on all segments, the terminal segment with hairs 1–3 mm long. Stipa comata by lemmas usually evenly white-pubescent, sometimes glabrous immediately above the callus and lower ligules often lacerate. The size of the lemmas is often at 15 mm long or longer and the awns often over 90 cm long. This sort of variation at this site also calls into question the distinction of Stipa curtiseta and Stipa spartea relative to both Stipa comata and Stipa neomexicana. |
