for half its length, bearing above several alternate flowers on divergent puberulous 
pedicels 4 lines long, supported by acute bracteoles 13 line long; sepals acutely oblong, 
puberulous, 14-3 lines long, each with a rather large, acute, broad inner scale; tube of 
corolla cylindrical, 6 lines long; segments inequilateral, acute, 2 lines long; stamens 
inserted in the middle of the tube; anthers slender, with acuminate summits, semi- 
exserted, biaristate at the base; appendages semi-exserted beyond the annular ring.

sicc. in herb. meo (no. 1567 et 4628). 
A plant very distinct from De Candolle’s species (Gaudichaudii), having oval leaves 
with a short very sudden acumen and long deflexed racemes ; the branches are gla- 
brous, pallidly terete, subflexuose, striolate, verrucosely lenticellate, dilated at the axils, 
which are 44-64 in. apart, with a crenulate transverse ring of many stipuloid fleshy 
glands; leaves ovate or oblong-ovate, rounded and often obsoletely cordate at the base, 
suddenly and shortly acuminate or retuse at the apex, chartaceous, with scarcely revolute 
margins, green and glabrous above, with about 6 pairs of slender semi-immersed nerves 
arcuately conjoined, yellowish opake beneath, subscabrid, somewhat hispidulous on the 
prominulent midrib and nerves, 31—5 in. long, 2-3 in. broad, on patent subpuberulous 
petioles 3 lines long; racemes lateral and solitary at the nodes, 4-5 in. long, on a rather 
slender subdeflexed peduncle, bare at its base for a length of 13-23 in., subangular, 
subverrucose, subglabrous, subpuberulous, somewhat flexuose above and bearing many 
alternate flowers on slender patent or reflexed pedicels 14 line apart, 4 lines long, sup- 
ported by linear acute bracteoles 4 line long; sepals oblong, acute, 24 lines long, 2 lines 
broad, with an inner acute 3-denticulate scale; corolla salver-shaped; tube 6 lines long, 
with a faucial annular ring and 5 linear semi-exserted appendages arising from below 
the mouth; segments oblong, inequilateral, expanded, 3 lines long; disk, ovaries, style, 
clavuncle, and stigmata as in the generic character; follicles 2, immature, 44-6 in. 
long, very strangulately torulose. 
A drawing of this species, showing its floral and carpological structure, is given in

Mus. Brit. Bahia (Lockhart). 
A species having subangular branches, at first clothed with spreading long rigid hairs, 
afterwards scabrid ; axils 5 in. apart; leaves oblong-ovate, roundish and plicately re- 
curved at the base, obtusely subacute at the summit, with a fine mucronate point, 
margins very revolute, rigidly coriaceous, dark olive-green above, opake, scabridulous 
and sulcate along the fine arching nerves and reticulate veins, palish glaucous-green 
beneath, opake, scabridulous upon the prominent midrib, nerves, and veins, 23-6 in. long 
13-23 in. broad, on petioles 23-4 lines long; raceme solitary and lateral at the nodes, 
14 in. long, on a fuscous reflexed peduncle bearing several alternate flowers on pedicels 
rather approximate and 2 lines long, supported by acutely ovate bracteoles 1 line long;
