 plerumque tridentata aut raro indivisa : dentibus late 

 ovatis, mucronulatis. Petioli tenues, dilatati. Fedun- 

 cull longissimi, uniflori, calycesque pilis glanduliferis 

 leviter sparsi. Lacinice cahjeince ovata*, acutai, muticse, 

 trinerves. Petala obovata, utrinque alba, triplinervia : 

 liervis lateralibus, curvatis, ramulosis ; medio simplici,

This species is totally distinct from all the varieties of S. hyp- 

 noides, one variety of which is often cultivated in the gardens 

 under the name, and mentioned in Donn's Cambridge Catalogue. 

 I am therefore happy in having an opportunity of giving a full 

 description of the real plant. In its native habitat it frequently 

 bears long solitary peduncles, terminated by only one flower : 

 but culture alters it in this respect.
