together forming three conical processes." These several 

 horn-like processes are more apparent in the state of the 

 bnd than in the fully expanded flower. 



Descr. This forms a much branched, obscurely pubes- 

 cent herb, three to four feet high, with a very thick, succu- 

 lent stem, rough and warted in maturity, and much 

 branched, the stem and branches everywhere glabrous, 

 striated or furrowed, green. Leaves four to six inches 

 long, ovato-lanceblate, acuminate, much serrated, tapering 

 into the footstalk, strongly nerved, the nerves sunk above, 

 elevated beneath. On one side of the base of the petiole 

 is a large kidney-shaped gland, which is decurrent on the 

 stem ; and a smaller spherical one on the opposite side. 

 Peduncle axillary, thickened at the base, bearing a short 

 panicle, or irregular raceme, of sulphur-coloured, large 

 flowers. Sepals two, small, spreading, membranous, obo- 

 vate, mucronate, pale greenish-brown. Petals (according 

 to De Candolle) four, of which the upper is broadly 

 obcordate, pale sulphur-colour, with a green horn at the 

 back, and a much smaller one in the sinus; two lateral 

 ones large, obliquely tvvo-lobed, falcate, curved upwards, 

 spotted with ferruginous dots ; lower sepal very large, 

 cucullate, spotted, ending in a rather long, incurved spur. 

 Fruit two inches in length, terete, angular.
