Description:
Species Description - Epiphytic and terrestrial shrub ca. 1.5 m tall; stem base to 2 cm in diam.; mature branches terete or obtusely angled, smooth or minutely striate, glabrate, tan or reddish-brown; twigs terete, obtusely angled or conspicuously flattened, minutely striate, glabrate or densely short-pilose. Leaves linear, linear-lanceolate, or elliptic-lanceolate, averaging 5-6 times longer than wide (4.5-)7.5-12(-14.5) X (0.5-) 1-2(-2.5) cm, basally narrowing, rounded and usually slightly cordate, apically long-attenuate to an ultimately blunt tip, glabrous, marginally strongly revolute (rarely flat); pinnately nerved, lowest primary nerves sometimes arcuate to about middle where they anastomose and form a collective nerve with remaining nerves which runs to leaf apex, midrib deeply impressed above and conspicuously raised beneath, lateral nerves and veinlets raised and conspicuous above, slightly raised but obscure beneath; petioles subterete, rugose and often longitudinally ribbed, 3.5-6.5(-9) mm long and 1-2.5 mm in diam., densely short-pilose adaxially becoming glabrate. Inflorescence solitary or rarely two in terminal axils, 8-28-flowered with lowest 3-8 nodes usually sterile, viscid; rachis conspicuously bluntly angled, minutely striate, glabrous, purple, 5.5-13 cm long and 1-2.5 mm in diam.; floral bracts conspicuously nerved, concave or cucullate, ovate, 3-6.5 X 2.5-4.5 mm, basally rounded and truncate, somewhat auriculate, apically acute to obtuse, glabrous, distal 2/3 of margin glandular-callose, dark purple with greenish tinge; pedicels subterete, striate, swollen apically, glabrous, 11-18(-24) mm long and 0.5-1 (-1.5) mm in diam., dark purple; bracteoles located up pedicel, conspicuously nerved, concave, ovate, 1.5-2.5(-3) x (0.5-)1.5(-3) mm, basally continuous (not articulated) with tissue of pedicel, apically acute, glabrous, distal 2/3 glandular-callose, dark purplish-green. Flowers: calyx glabrous, (5-)6-7(-8) mm long, sometimes slightly stipitate; hypanthium cylindric, rugose and ribbed, surface often muricate, (1.5-)2-3(-4.5) mm long, basally strongly apophysate and deeply lobed, green when immature, dark purple at anthesis but turning greenish after anthesis; limb cylindric or spreading, rarely campanulate, ribbed, (2-)4-4.5 (-5.5) mm long; lobes triangular, 1-1.5(-2) X (1.5-)2-2.5(-3) mm, erect after anthesis, completely glandular-callose or rarely margins slightly thinner than main body, purple; sinus obtuse to broadly rounded; corolla slightly constricted basally and narrowed at throat, densely short, white pubescent without with trichomes 0.2-0.4 mm long (rarely glabrous), sparsely pilose within, (16-)18-21,5(-22) mm long and 4-8 mm in diam., pale purple at constricted base, purple above, lobes triangular, 1-1.5 mm long, glabrous, reflexed at anthesis often exposing tips of anthers; stamens 15.5-19.5 mm long; filaments glabrous or more commonly with long ones medially pilose and short ones distally pilose, alternately 2-3.5 mm and 5-7.5 mm long; anthers alternately 15.5-18 mm and 12.5-14.5 mm long; thecae alternately 5.5-6.5 mm and 4-5.5 mm long; style exserted at anthesis. Berry 12-15 mm in diam.

Discussion:
Cavendishia stenophylla is distinguished by the combination of linear to narrowly elliptic-lanceolate leaves with strongly revolute margins and pinnate venation, small, glandular-callose floral bracts, continuous (not articulated) bracteoles, short-pilose corollas, and dark purple floral bracts, rachis, calyx, and corolla.Within sect. Callista it is allied to C. melastomoides. The two species show similar tendencies for higher positioning of the bracteoles along the pedicels, secund inflorescences, and stems somewhat swollen at base. Cavendishia stenophylla differs in the characters mentioned in the key and further by eglandular, more floriferous, usually thicker rachis, smaller and differently shaped floral bracts, continuous bracteoles, and different color patterns.
