green, and burst in front somewhat laterally by a longitudinal 
fissure, throwing out a yellowish-coloured pollen. The ova- 
rium is globular, somewhat flattened at the summit, and 
divided into 2, 3, or 5 indistinct lobes. The style is erect, 
cylindrical, somewhat enlarging at its extremity. The stigma is 
oblong, cordate at base, tapering, obtuse at apex, formed of 2 
indistinct flattened adnate lobes, fleshy, green, and shining. 
The berry is cernuous, fleshy, and 2-celled ; the seeds are flat- 
tened, reniform, subrhomboidal, with a marginal hilum; the 
testa is somewhat fleshy and rugous; the embryo is slender, 
filiform, almost annular, and imbedded in fleshy albumen ; the 
radicle, which points toward the hilum, is very long, straight 
at the extremity, and bent above; the cotyledons are short, 
slender, semiterete, curved, and terminate near the extremity 
of the radicle.* 
TRECHONZATES. 
Among the few interesting plants gathered in my journey 
over the Cordillera in the January, 1825, was one found upon 
the eastern descent of the Cumbre, towards Las Cuevas, at an 
altitude of 11,500 feet, in a very dry and arid situation, which 
circumstance suggested the above generic name, from rpnxo 
locus asper, vaérns incola. Specimens of the same plant have 
lately been sent to this country by Mr. Bridges; and as it has 
not been yet described, I now offer the result of my long 
recorded observations, from which it will be seen to possess 
characters very distinct from Jaborosa and its congeners.
