Description Flowers usually 6-merous, each closely subtended by two pairs of bracts. Hypanthium campanulate or cup--shaped, usually thick-walled. Calyx truncate to deeply lobed. Petals usually large, commonly unsymmetrical. Stamens iso- morphic; filaments short; anthers coherent in a ring, short, oval or oblong, abtuse or rounded at the summit, laterally flattened, opening by two minute pores; con- nective usually slightly prolonged or dilated at base into a dorsal spur. Ovary wholly inferior, usually 6-celled; stigma punctiform or capitate. Woody plants, often epiphytic or climbing by adventitious roots when young, sometimes reaching a large size, with conspicuous flowers solitary or fascicled in the axils of the leaves; leaves with the secondary veins usually close together, straight, and parallel.
Distribution At least 50 species, most numerous in the northern Andes; several others occur in other parts of Central America.
Key a. Bracts, both outer and inner pairs, connate almost to the summit. b. Bracts glabrous externally or essentially so.- -.. 1. B. WOODSONII. bb. Bracts densely pubescent to hirsute externally. c. Petals coarsely tuberculate; sepals tipped with a reflexed foliaceous appendage; younger stems glabrous or merely furfuraceous ............... 2. B. CALYCOSA. cc. Petals not tuberculate; sepals unappendaged; younger stems pubescent to hirsute. d. Flowers sessile; leaf-veins beneath coarsely hirsute ------------------------- 3. B. CRINITA. dd. Flowers on pedicel 5-20 mm. long; leaf-veins merely pubescent beneath.- -....................... 4. B. BRUNNEA. aa. Outer bracts, and usually also the inner, separate to the base. (Since the pedicel passes imperceptibly into the hypanthium, they may appear to be connate for a small part of their length.) b. Outer bracts conspicuously longer than the hypanthium and calyx combined. c. Calyx truncate, the lobes represented by 6 minute tubercles; pedicels glabrous; secondary veins about 0.5 mm. apart - 5. B. GRACILIS. cc. Calyx-lobes manifest, triangular with concave sides, about 1.5 mm. long; pedicels stout, pubescent; secondary veins 1-1.5 mm. apart.- 6. B. FOLIACEA. bb. Outer bracts distinctly shorter than the hypanthium. c. Calyx truncate, the lobes represented by minute tubercles ................. 7. B. PAUCIFLORA. cc.
