1853. 
Trees or shrubs, more or less pubescent, the branches terete or subangulate. Stipules 
interpetiolar, large, persistent, glandular within at the base. Leaves opposite, petiolate, 
large, membranaceous or subcoriaceous. Inflorescence terminal, the flowers small, 5-parted, 
cymose, the cymes arranged in racemose panicles; hypanthium oblong-ovoid; calyx 5-lobate, 
the lobes persistent, subequal and rounded, or one of them dilated into a large foliaceous 
petiolate colored limb; corolla short-funnelform, the tube terete or pentagonal, villous in the 
throat, the lobes obtuse, imbricate in bud, 2 of them exterior. Stamens 5, inserted in the 
corolla-throat; filaments short or elongate; anthers dorsifixed, versatile, exserted, obtuse or 
apiculate. Disk annular. Ovary 2-celled; style included or exserted, glabrous or pilose, 
short-bifid; ovules numerous, crowded, the placentae adnate to the septum. Capsule small, 
oblong or subglobose, 2-celled, many-seeded, septicidally bivalvate. Seeds minute, horizontal, 
3-angulate, marginate, reticulate; endosperm fleshy; embryo minute, clavate, the cotyledons 
obtuse, the radicle cylindric. 
Type species, Macrocnemum coccineum Vahl.

Shrub or small tree, 4-6 meters high, the branches stout, subquadrangular, grayish or 
brownish, usually fulvous-pilose when young but sometimes glabrate, the internodes short; 
stipules narrowly triangular-oblong, 1.5—2 cm. long, acuminate or attenuate, thick, brown, 
strigillose outside or glabrate; petioles stout, 0.5—-2.5 cm. long, sulcate above, rounded beneath, 
strigillose, pilosulous, or glabrate; leaf-blades oblanceolate-oblong, obovate, obovate-oblong, 
or broadly oval-obovate, 14-65 cm. long, 4.5-35 cm. wide, narrowed to the subobtuse to at- 
tenuate base, sometimes subabruptly acuminate, acute or abruptly short-acuminate at the 
apex, thin, bright-green above, sublustrous, glabrous or sparsely pilosulous along the costa, 
the venation plane or prominulous, scarcely paler beneath, dull, sparsely or densely strigillose, 
especially along the veins, sometimes densely short-pilose, the venation prominent, the costa 
slender, the lateral veins slender, 15-32 on each side, divaricate, nearly straight, the margins 
plane; inflorescence 30-40 cm. long, the peduncles stout, 1-5 em. long, the cymes numerous, 
dense, few- or many-flowered, short-pedunculate, the rachis glabrous or pilose; bracts tri- 
angular, small, the bractlets minute, subulate, ciliate; hypanthium 2-2.5 mm. long, yellowish- 
tomentulose or strigose; calyx-lobes about 1.5 mm. long, broadly oval, rounded at the apex, 
erect, glabrous, sometimes ciliolate, one of the lobes often expanded into a red limb, this oval- 
oblong to narrowly elliptic, 3.5-7 cm. long, 1-2.5 cm. wide, obtuse at the apex, borne on a 
petiole 1-3 cm. long, glabrous or appressed-pilose; corolla yellow or orange, 5—8 mm. long, the 
tube equaling or longer than the lobes, strigillose outside; filaments about equaling the corolla- 
lobes, the anthers 2-4 mm. long; capsule subglobose, 4-5 mm. long, pilosulous; seeds 1 mm. 
long or shorter.

Erect or prostrate shrubs, much branched. Leaves small, opposite, crowded, sessile, 
fleshy. Stipules united with the petioles into a sheath. Flowers small, solitary, sessile, 
yellow, bibracteate, sericeous; hypanthium very short; calyx 4-lobate, the lobes lance-linear, 
sometimes alternating with small teeth, persistent; corolla salverform, the tube curved, gla-
