A species distinguished by its smaller leaves on short petioles, and smaller flowers ; 

 subscandent, slender branches, puberulous above with short retrorse hairs; approxi- 

 mate axils much incrassate, and charged on each face between the petioles with 

 4 warty ovate glands 1^ line long ; leaves obovate, obtuse at the base, mucronate, 

 coriaceous, fuscous, glabrous, nerved but veinless, 1-lj in. long, 6-9 Hnes broad, on pu- 

 berulous petioles 2 lines long ; racemes axillary, glabrous, longer than the leaves, beariag 

 2 or 3 yellow flowers on thick, rigid, spirally twisted pedicels 6 lines long ; sepals subu- 

 lately ovate, 1^ line long, each with 2 inner basal bifid scales ; tube of corolla 1 in. long 

 contracted at the base below the middle, swelling in a funnel-shape above ; segments 

 obscurely ovate, dolabriform, with undulated margins ; stamens inserted in the contraction 

 of the tube ; disk of 2 rounded lobes much shorter than the 2 ovaries.

A species near the preceding, but with more rigid and straighter branches, and larger 

 flowers. Its branches are glabrous, terete, much incrassate at the axils, which are 2-2^ 

 in. apart, and charged on each side, between the petioles, with about 8 large, subulate, 

 warty glands soon caducous ; leaves elliptic or obovate, rounded or obtuse at the base, 

 suddenly acuminate at the summit, chartaceous, smooth, reddish green, 2|— 3^ in. long, 

 1^2 in. broad, on slender petioles 9-10 lines long ; racemes terminal or axillary, on a 

 peduncle 1 in. long, bearing upwards about 7 white flowers on alternate pedicels 12-15 

 lines long ; sepals ovate-acuminate, 2 lines long, with 2 inner basal bifid scales ; tube of 

 coroUa 18 lines long, narrowed at the base for one third of its length, thence swelling in a 

 campanular form to a breadth of 8 lines in the mouth ; segments rhomboidaUy ovate, dola- 

 briform, mucronate, 18 lines long, 12 lines broad ; stamens seated in the contraction of 

 the tube, with purplish anthers, having at their base 2 parallel obtuse prongs as long as 

 the filaments ; disk of 2 rounded lobes ^ the length of the 2 ovate ovaries ; follicles 9^ in. 

 long. If line thick. Miiller mentions a variety from the province of Minas, with ternate 

 leaves, which may be regarded as a distinct, undescribed species.
