This is much like Xysmalohium gramineum, S. Moore, in general appearance, 

 but differs entirely in floral structure, see note under that species on p. 303.

I cannot retain this plant as a distinct genus; the characters claimed for it by 

 Dr. Kendle are, an imbricate estivation, and coronal-lobes connate at their base and 

 shorter than the staminal-column. It is contrasted with Xysmalohiuin, but that 

 genus has also an imbricate (rarely valvate) estivation, and in soma sjiecics (A'. 

 rhomhoideum, X. memhraniferiim, &c.) the coronal-lobes are more or less connate at 

 the base, and are shorter than the staminal-column in several species. In habit au«l 

 estivation it agrees with species of Asclepias, Xi/smalofyimn, ami ^c/ii:o'/lo\st(in. The
