This appears to be a very distinct species from any hitherto 
published ; but evidently allied to tbe Ozalis (Biophytum) 
sensitiva, L. Here, however, the root is long, stout, fusiform, 
9r scarcely branched, sending out a few fibres; the upper 
Part rises into a short, erect, simple stem, 2-4 inches long, 
more or less scarred with the remains of fallen leaf-stalks, 
and crowned with a tuft of leaves 6-8 or more inches long, 
Pinnated with from 14-18 opposite or alternate pairs of ob- 
long, oblique, and sharply acute leaflets, costate, truncate at 
the base, marked with numerous oblique nerves, glabrous, 
an inch to an inch and a half long. Petioles short, and - 
with the rachis downy, tipped with a subulate point. Pe- 
. duncles axillary, 2-3 inches long, xo » bearing a globose | 
head of dense, bracteated flowers. B s rigid, subulate,
