Of this polymorphous species the following forms have been 
collected: f. divaricata (Schrank) Gelert, (N. 65, 1776), f. Drouetii 
(F. Schultz) Gelert (N. 1113, 1156, 1451) and f. eradicata (Lae- 
stad.) Gelert (N. 1445); the two latter are mountain forms of which 
f. eradicata is thinnest and smallest. The European form which 
has floating leaves (f. diversifolia (Schrank) Gelert) has not been 
found in Asia; all the authors (e. g. Hooker p. 16, Fedtschenko 
p. 411) write that tliey have never seen specimens from Asia with 
floating leaves.
