Caperonia palustris, St. Hil., Pi. Remarq., 245.
Asuncion (382); Pilcomayo River (1047); Caballero (438).
January-May.
This genus differs principally from the preceding Euphorbiaceous
genera in having its fruit in united triplets, the 3 cocci generally
hispid or echinate. The species here noted is a coarse plant 6-9
dm. high, the stems beset with spreading, translucent setae, each
tipped with a minute oblong head. Nos. 382 and 1047 have broad
oval crenate-serrate leaves, while the leaves of 438 are long, narrow
lanceolate and sharply serrate. The last differs so greatly from the
other forms that it might almost be considered a distinct species.
Some specimens of 1047 were distributed as Q^ castaneaefolia, St.
Hil., which very closely resembles this species. >
