Characteristics

Epiphytic shrub 0.5-1.0 m high, glabrous throughout except for the filaments; branchlets thick, terete. Leaves coriaceous when dry, oblong lanceolate to narrowly elliptic, 26-37 cm long, (3.5-)5.5-9.3 cm wide, basally cuneate, apically acute to gradually acuminate, entire and narrowly revolute, pinnately nerved, the midvein and the principal veins moderately elevated above, prominently so beneath, the veinlets reticulate and conspicuous; petioles rugose, 8-12 mm long, 3-4 mm in diameter. Inflorescences axillary, shortly racemose or corymbose at anthesis, 6-10-flowered with practically no peduncle; rachis 6-10 mm long, angled; pedicels 8-12 mm long, 1-1.5 mm in diameter, each subtended by a papery, ovate to deltoid, acute, usually minutely toothed bract 1.5-3 mm long and with 2 submedial, often toothed bracteoles 1.5-2 mm long. Flowers with the hypanthium and the calyx broadly campanulate at anthesis, 7-8 mm long, 5-7 mm in diameter at its summit, clearly disarticulating from the pedicel by a sharply delineated groove, the calyx limb slightly coriaceous, suberect, ca. 3 mm long including the lobes, the calyx lobes deltoid, acute, 2-2.5 mm long, basally 2-3 mm wide; corolla glabrous, somewhat fleshy, truncately conic at anthesis, 6-10 mm long, at the base 5-8 mm in diameter, contracted apically, the lobes 5, deltoid, acute, 1-1.2 mm long and wide; stamens 10, the filaments submembranaceous, distinct, ligulate, 1.5-2 mm long, puberulent ciliolate, apically tapering, the connectives either alternately obscurely 2-spurred and spurless or all spurless, the anther sacs rigid, 3.5-4 mm long, the base conspicuously in-curved each with 2 cylindric-conical, connate tubules 1.5-2 mm long which dehisce introrsely by elongate oval clefts about as long as the tubules; stigma ca. 0.5 mm in diameter when receptive. Mature berry not seen.
