Genus

Angiosperms > Gentianales > Gentianaceae

Characteristics

Shrubs or trees. Branches with leaves crowded towards apices; nodes with low interpetiolar sheaths. Leaves petiolate, 18-105 cm long; multi-veined. Inflorescences terminal, a dichasial cyme, inflorescence branches yellow or orange; bracts and bracteoles scale-like. Flowers pedicellate, with 4 decussate calyx lobes and 8-10-merous corolla and androecium, actinomorphic; calyx divided to the base, coriaceous, campanulate, lobes elliptic to orbicular, convex, without dorsal keel but thickened dorsally, apex obtuse; corolla bud apex rounded; corolla fused for about 1/2-3/4 of length, coriaceous and fleshy, tubular, slightly funnel-shaped, or salver-shaped, 7-20 mm long; androecium actinomorphic; stamens inserted in middle of corolla tube, of equal length, filaments fused into a staminal tube, anthers linear, free, connective apex apiculate; pollen in monads (rarely tetrads; P. maguireorum); pistil with nectary disk around base, stigma capitate. Fruit a berry, with calyx persistent and corolla deciduous; seeds circular to elliptic, flattened, not winged, testa pattern reticulate, pitted.
More
Flowers with pedicels 7-14 mm long and 2-3 mm broad; calyx-lobes 4 (the inner pair with margins overlapped by the outer pair), suborbicular to obovate, apically rounded, crassulate and coriaceous, membranaceous only at the margin, yellow, 5.5-8.5 mm long, a tube not apparent; corolla white to green or yellow, the tube short-campanulate and 2-3 mm long, the lobes 10, 4-6 mm long, ovate-lanceolate, basally auriculate, strongly imbricate, incurving at the tips; stamens 10, the anthers linear or slender-lanceolate, 4-5.5 mm long, the filaments connate by a membrana-ceous sheath ca 1 mm long which is attached near the base of the corolla-tube; ovary elevated on a fleshy disc to 1 mm long, ovoid, 2.5-4.5 mm long, the style 1 mm long or less, the stigma capitate and rather conspicuous. Fruit baccate, indehiscent, turbinate, ca 1.5-2 cm long and broad, 2-4 locular; seeds so, mostly oblong, brown, somewhat angular, 4-5.5 mm long, the testa pitted.
Shrubs or small trees 0.3-5 m high, simple or sparingly branched. Leaves opposite; petioles 0.4-4 cm long, 2-7 mm broad, usually glabrous, connected by a short and truncate stipule-sheath; blades elongate-obovate or oblanceolate to oblong or anguste-elliptic, apically acuminate or subacuminate, basally acute to long-attenuate, 30-75 cm long, 7.5-18 cm broad, usually broadcast toward the apex or near the middle, simple, entire, glabrous, much darker green above than below, the midvein conspicuous and raised below, the secondaries typically more than 30, pinnate, alternate, arcuate-ascending, the reticulation faint or obscure on both surfaces. Inflorescences cymose-corymbose, solitary, terminal but often over-topped by lateral branches, several-flowered, with 1 or 2 orders of branching, the branches covered with a yellow granular powder which is readily shed.
