margins being whitish, membranaceous, the more central por- 
tion as well as the tube being marked with numerous purplish 
brown reticulations, and a few scattered hairs; the filaments 
are slender, nearly the length of the tube of the corolla, quite 
free to the base, whence they originate from a small adnate. 
ring; they are smooth and slightly pubescent at base, erect, 
and curving downward toward the apex; the anthers, which 
are thus inverted, consist of two nearly globular adnate lobes, 
divaricate at base, bursting longitudinally by lateral fissures ; 
they are without any sensible connective, and are fixed dor- 
sally near the base, on the apex of the filament. The ovarium 
is round, pubescent, and partially imbedded in the fleshy 
torus, is 2-celled, with many ovules, adnate to a central en- 
largement of the dissepiment ; the stigma is clavate, consist- 
ing of 2 adnate corrugated lobes. At the time I collected © 
this plant, there was no indication of fruit, nor is any seen in 
Mr. Bridges’s specimens, but from analogy it may be assumed 
to be a berry.*

This plant, according to Tweedie, is cultivated in Tucuman, 
where it is “used as mustard,” from which it may be inferred 
that the seeds have a pungent taste, for no part of the dried 
plant exhibits any such flavour. It grows in broad patches 
about a foot high; the stems are covered with soft hairs, and 
the axils are about 3in. apart ; the leaves, 3 in each axil, are 
of unequal size, the largest being 7 in. long, including the 
rather short decurrent petiole, and 4 in. wide; these are pin- 
nately laciniate; the smaller ones are about 4 in. long and
