SOUTH AMERICAN PLANTS. 103 
The calyx is 4 lines long, somewhat campanulate, glabrous, 
purplish green, with a long woolly apex to each broad short 
tooth. The corolla is tubular, contracted at base within the 
calyx, expanding above into a somewhat funnel-shaped tube, 
ofa greenish yellow hue, about 1% inch long, and 3 lines in 
diameter, quite glabrous, the border is cleft to the mouth into 
5 equal oblong lobes, the margins being broadly conduplicate 
and tomentous in estivation, but glabrous when fully ex- 
panded : the base of the tube is somewhat pubescent within, 
thickened, and exhibiting 5 raised fleshy ribs, surmounted by 
a thick broad gland, which is tufted with long white hairs, 
from these arise the filaments, dilated at their origin, glabrous, 
tapering upwards into a slender form, and exserted: the 
anthers are of a lurid green, deeply cordate, of 2 oval lobes, 
fixed in the sinus on the apex of the filament. The ovarium 
is wholly enclosed in the persistent cup-shaped base of the 
corolla, which here always falls off by a horizontal line: it is 
supported on a small 5-lobed disc, which is shortly stipitate, 
and quite free. The capsule is oval, smooth, LO lines long, 
5 lines diameter, supported by the cupuliform enlarged calyx, 
is divided nearly to the base into 4 valves, the thickened dis- 
sepiment becoming free, to which the seeds are attached by a 
number of projecting fleshy seminiferous plates. The seeds 
are ovate, somewhat angular, with a ventral excavation, in 
which the hilum is seen a little above the middle. The testa 
is tuberculated, with intervening small transverse striz, and 
encloses an oval fleshy albumen, in the centre of which the 
embryo is placed, which is erect and almost straight, but 
which viewed in front is very little sigmoid, and sideways 
slightly curved inwards: the radicle is thick and terete, the 
cotyledons being somewhat broader, slightly compressed and 
fleshy: I have sometimes found 3 cotyledons : they are about 
1 the length of the embryo.*
