striate. 
The embryo is very laxly cellular, like the others the plumu- 
la is, as it were, bi-lobed, a second rudimentary leaf being early 
developed, directed from the cotyledon, the funicle is rather 
long, and arises from a largish cell firmly adhering to the apex 
of the nucleus, and containing a grumous nucleus.

A watery cellular herb, with verticillate linear subulate 
toothed sessile leaves, dilated into membranes on either side at 
the base. Spath subcylindrical, fimbriate toothed at the apex, 
contents oblong ovate reddish opaque with a bi-dentate

large, apparently simple, whitish, opaque owing to the granu-

The flowers are dicecious, the male consisting of a large 
anther, bursting irregularly at the apex? and contained with-
