especially those on the lower branches, which are always more abundant 

 and larger than the upper ones, on account of their orange-scarlet 

 colour ; peduncles drooping-pendulous from the uppermost axils ; the 

 common peduncle 1 to 'J ft. long, much flattened-dilated above towards 

 the insertion of the pedicels, striate ; pedicels subverticillate, dichoto- 

 mous, recurved upwards, thick, very rigid ; calyx fleshy-coriaceous, 

 green, tubular-campanulate, variously cleft or bilabiate, the upper lip 

 a little narrower and longer than the lower, both lips rounded or very 

 obtuse, quite entire, with a narrow scarious blackish membrane at the 

 margin, the lower lip supplied outside with roimd irregularly arranged 

 glands : corolla coriaceous (except the lobes), rigid, smooth outside, 

 brittle, orange-scarlet or pale red outside, deep scarlet or orange- 

 cinnabar inside, ringent : the lower part of the tube funnel-shaped, 

 yellowish both inside and out, constricted a little above the base, then 

 abruptly dilated and curved ; the limb very wide, bilabiately 4-cleft, 

 that is, the upper lip slightly bifid and the lower lip more deeply trifid, 

 all the lobes repand-dentate on the margin, somewhat obtuse, corru- 

 gated-crisp oriplicate-undulate, scarcely ever fully expanded, scrobicu- 

 late-veiny on the inner face ; the three lower lobes subequal, long, 

 with a thick nerve and longitudinally striate : stamens 5, inserted at 

 the middle of the corolla-tube where it is constricted and curved 

 forwards, included, 4 of them didynamous and fertile, the fifth 3 or 4 

 times shorter sterile and without an anther ; filaments cylindrical, 

 yellowish, but little attenuate towards the apex, thinly hirsute with 

 whitish hairs at the base : anthers large, yellowish, attached at the 

 apex, 2-celled, the cells longitudinally dehiscing and divaricate in a 

 sagittate manner ; the sterile stamen placed between the two shorter 

 fertile stamens and corresponding to the cleft or sinus of the upper 

 lip of the corolla ; disk perigynous, thick, yellowish, fleshy, turgid, 

 annular, smooth, lying at. the bottom of the calyx and surrounding 

 the base of the ovary ; ovary sessile at the bottom of the calyx, 

 conical-cylindrical, 2-celled, the cells many-ovuled ; style elongated,, 

 exceeding the stamens, cylindrical, flattened towards the apex ; stigma 

 consisting of two ovate-lanceolate lamellae stigmatose on the inner 

 face ; fruit pendulous, conical-cylindrical, 1 to Ih ft. long, 2 to 3 in. 

 in diameter, green, somewhat warted, a little compressed on two sides. 

 more or less dusky when ripe ; seeds numerous, not winged, nestling 

 in pulp whioh is pervaded with woody fibres. The fifth stamen is 

 always present, and in only one instance out of more than fifty flowers 

 examined was it found fertile. At the outskirts of primitive forests, 

 especially by streams in Sobatos de Bumba and Bango Aquitamba, 

 and about Sange by the Delamboa rivulet ; fl. May to Dec, fr. Jan. to
