Of this polymorphous species the following forms have been 

 collected: f. divarkata (Schrank) Gelert, (N. 65, 1776), f. Drouetii 

 (F. Schultz) Gelert (X. 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 

 lias 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 they have never seen specimens from Asia with 

 floating leaves.
