Straggly to compact, epiphytic or terrestrial shrubs. Leaves alternate, petio- late, coriaceous, pinnately veined or plinerved. Inflorescence axillary or termi- nal, subfasciculate or racemose with few to many flowers on deciduously bibrac- teolate pedicels. Flowers with the hypanthium articulate with the pedicel, short cylindric or campanulate; calyx limb erect and spreading (3-4)5-lobed, the seg- ments subacute and triangular; corolla subcylindric or elongate urceolate, 5- parted, the lobes triangular and subacute; stamens usually 10, equal, usually about half as long as the corolla, the filaments distinct or connate, dorsally at- tached to the anthers near their bases, the anthers stout with strongly granular thecae, the tubules about as long as the anther sacs, either laterally connate or fused into a single tubule, rarely completely distinct, opening by elongate, dis- tinct or fused, introrse clefts; style filiform and about as long as the corolla or longer, basally surrounded by an annular or cupuliform disc; the ovary inferior.
