Description:
Species Description - Epiphytic shrub 7-10 dm tall or terrestrial and 1-3 m tall; stem base to 2.5 cm in diam.; mature branches terete, smooth or minutely striate, glabrous, tan to reddish-brown, usually with a thin, whitish-waxy layer over branches; bark reddish-brown; twigs subterete to bluntly angled, striate and often coarsely ridged, glabrous, reddish-brown. Leaves lanceolate to lance-elliptic, (3-)5-9(-11) x (1-)2-4 cm, basally obtuse or rounded with lamina often short-decurrent along petiole, apically short- or rarely long-acuminate and often abruptly so, glabrous or often with numerous short hairs at base of midrib adaxially, usually soon glabrate; 5(-7)-plinerved, midrib plane or more commonly weakly impressed above, lateral nerves usually raised and conspicuous rarely weakly impressed above, veinlets all raised and conspicuous to obscure above, all nerves raised beneath but veinlets obscure; petioles subterete but usually flattened adaxially, rugose and often coarsely ridged, 7-13 mm long and 1.5-2 mm in diam., glabrous to weakly pilose adaxially when young then persistent or glabrate when mature. Inflorescence (2-)3-6(-9)-flowered, obconic to spherical in bud; rachis flattened, bluntly angled, striate, viscid, glabrous, (0.3-)0.6-1,2(-3.2) cm long, pale green when fresh, usually with minute cartilaginous teeth at base; floral bracts usually translucent when dry, smooth or rarely slightly ribbed, oblong to oblanceolate, or oblong-lanceolate, (15-)20-30(-40) X 5-10(-20) mm, usually with minute, red glandular fimbriae abaxially, basally narrowed and somewhat auriculate, apically rounded or obtuse and usually emarginate or when young notched with notch almost completely filled with callus tissue, pink or pale green but suffused with pink along margins and at base when fresh, drying green; pedicels swollen distally, ridged, glabrous (6-)8-13(-l 5) mm long and (0.5-)1-1.5 mm in diam., pale green to cream-colored and often suffused with pink when fresh, occasionally with cartilaginous teeth at distal end; bracteoles basal, linear-lanceolate, 1-2.5(-3) X 0.5-1 mm, apically acuminate and glandular-callose in the distal ½-2/3, pale green when fresh. Flowers: calyx glabrous, 5-7(-10) mm long, pale green sometimes suffused with pink when fresh; hypanthium cylindric, weakly rugose, strongly ribbed, (1.5-)2-3(-4) mm long, basally apophysate and deeply lobed with lobes parallel to hypanthium axis and extending to or just below articulation; limb campanulate to cylindric, smooth or weakly ribbed, minutely papillate when dry, (2.5-)3.5-4.5(-6) mm long; lobes triangular, (0.7-)1-1.5(-2) X 2-3 mm, sometimes flaring outward at anthesis, erect after anthesis, completely or only distal 2/3 glandular-callose; sinus obtuse, broadly rounded, or flat; corolla slightly constricted basally and narrowed to throat, often translucent when dry, 20-24(-30) mm long and 5-7 mm in diam., glabrous or rarely pilose, pink to white or whitish at base and apex with an otherwise pinkish-violet to rose-red tube, lobes triangular or oblong, acute, ca. 1 mm long, reflexed at anthesis, tips often glandular-callose, white with pinkish or violet margins; stamens 19-24.5 mm long; filaments densely pilose, alternately 2.5-5 mm and 5-10 mm long; anthers alternately 17-22 mm and 13-20 mm long; thecae 4.57 mm long; style 22-29 mm long. Berry ca. 9 mm in diam.

Discussion:
Cavendishia subfasciculata has two slightly different color phases which are correlated with geography. In western Chiriquí Prov., around Boquete and Cerro Horqueta, the floral bracts are greenish to pinkish-green and the corollas pinkish-violet to rose-red; while in eastern Chiriquí around Cerro Homito and in Veraguas at Cerro Tute the bracts are pink and the corollas pink to white. The corollas in the only flowering specimen from Cerro Tute also lack glandular-callose lobes.Within sect. Callista, C. subfasciculata is most closely related to C. morii and its allies by virtue of their normally glandular-callose corolla lobes. However, it also shows affinities to C. megabracteata, which also has emarginate floral bracts, few-flowered obconic to spherical inflorescences, similar coloration of floral bracts and corollas and non-glandular-callose corolla lobes (in the Cerro Homito-Cerro Tute populations). It may be distinguished, however, from C. megabracteata by its overall smaller size, its habit which presents a fuller and more dense appearance, by its slightly decurrent leaf bases, and by its leaf venation.
