not far from the truth in describing superficial leaves or sti- 
pules to this plant, The lower leaves are larger and distichous, 
the upper or smaller ones more or less imbricated, and generally 
curved upwards. The denticulation of the scales varies 
both in American and Indian specimens.

* This Tittle groupe, although not proposed by any preceding author, appears 
to us to be an extremely natural one, Stipules are present, and the leaves ^ 
bifarious and distichous, as in the Stachygynandra ; but here the leaves and com 
pressed branches are combined, and form, as it were, but one substance. x 
stipules are in one series, sometimes on the upper as well as on the under si
