Clinandrium cucuUalum, margine membranaceo saepe tripartito. 



At flrst siehl this would seem to be a distinct genus, and it may be hereafter 

 considered so. Bui if any bolanist should ihink the structnre of ihe crest available 

 for a generic character, I would remind him, that, although there is no apparent ana- 

 logy beiween ihe crest of some of ihe Trymenia and ihat of the Isanthia , so neither 

 do agree among each other in that respect, ihe crests of every species except brevi- 

 folium and coronarium being lormed upon a different plan. and 0. ciirosmum having 

 no crest at all.
