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. 1t 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 4in. wide; these are pin- 
nately laciniate; the smaller ones are about 4 in. long and 
23 in. broad, and are angularly sinuate. Numerous flowers 
are crowded together in a fascicle on one side of each axil, the 
peduncles being 9 lin. long, with a glabrous, spathulate bract, 
at the base of each, from 2 to 9 lin. long. "The calyx is 
deeply cleft into 5 acuminate, subulate, membranaceous, 
green segments, pilose, 2 lin. long. The corolla is of a dusky 
green, less than half the size of that of the former species, 
sparsely covered with long, soft pubescence, broadly campanu- 
late, submembranaceous, veined, and deeply divided into 5 
* A representation of this species is given in plate 7 of the “ Illustrations 
of South American Plants."
