Explication des figures p, 207 :
K : Orobanche rameuse qui est attachée sur les racines du glouteron K2 : on a fait représenter deux pieds de l'orobanche, pour que l'on pût voir la façon dont les racines d'un pied se cramponnent sur celles de l'autre.
N : partie de l'orobanche K, appliquée sur une partie de celle du glouteron ; on y distingue encore plus aisément comment les mamelons sont adhérents. O : Partie de la racine du glouteronoù l'on voit les cicatrices que l'orobancche y a faites ; l'ouvrture du suçoir qui est circulaire , se voit en petit o, l'écartement des fibres de l'écorce en petit o2.

P : Partie de la racine de l'orobanche K, détachée de la racine du glouteron, afin que l'on vît plus distinctement les mamelons.
