Description:
Species Description - Weakly erect, epiphytic shrub to 3 m; stem base about 3 cm in diameter. Mature branches terete, smooth to minutely striate, glabrous, tan, grayish-red, or reddish-brown; immature branches and twigs of new growth terete to bluntiy angled, smooth or striate, glabrous, tan, infrequently provided with caducous, globular glands along recent growth. Petioles terete to subterete sometimes flattened adaxially, rugose, 4-8 mm long and 1-1.5 mm in diameter, densely white puberulous when young becoming glabrate, tan to reddish-brown. Leaves elliptic, 4.5-8 cm long and 1.5-3.5 cm broad, basaUy cuneate or sometimes attenuate onto petiole, apically caudate-acuminate, acumen 1.5-2(-2.5) cm long (averaging one-quarter to one-third total leaf length), brownish- to grayish-green or tan w h e n dry, glabrous or slightly puberulous at base of midrib w h e n young then becoming glabrous; 3—5-plinerved, midrib, lateral nerves, and veinlets impressed to slightly elevated and conspicuous above, all veins raised beneath but usually only midrib conspicuous; newly unfolding leaves often densely provided with caducous, globular glands on upper surface and reddish glandular fimbriae beneath. Infiorescence viscid, 6-9(-11) flowered; rachis complanate, bluntiy angled, sometimes flexuous, smooth or minutely striate, glabrous, 1.5-4.5 cm long and about 1 mm in diameter at base, pale green suffused with red when fresh but drying brick red, infrequently provided with few scattered globular glands. Floral bracts glabrous, slightly ribbed, smooth, rugose or muricate, oblong to oblanceolate, basally narrowed and truncate, apically acute or rounded, 15-25 mm long and 5-9 mm broad, red, provided along each margin with 11-12 sessile, globular glands to 0.5 mm in diameter these often caducous. Pedicels terete to angled, swollen at both ends, minutely striate, glabrous, 4-7 mm long and 0.5-1 mm in diameter, pale green w h e n fresh but drying brick red, provided with few scattered globular glands and cilia especially distally. Bracteoles linear to linear-lanceolate, l-2(-4) mm long and about 0.5 mm broad, apically provided with a hastate, callose-thickened gland which breaks off easily, marginally with a few, globular glands. Calyx glabrous, 3.5-4.5 mm long, pink at anthesis; tube cylindric, smooth or rugose, 1.5-2(-2.5) mm long and 2-3.5 mm broad (2 mm at anthesis), basally slightiy apophysate, most noticeable in early fruit, provided with numerous scattered globular glands, which do not obscure surface of tube; limb campanulate to erecto-patent, rugose, ribbed, 1.5-2.5 mm long, provied with a few scattered glands simllar to those on tube; lobes triangular, obtuse, 0.5-1 mm long and about 0.5 mm broad, erect after anthesis, completely or only marginally callose-thickened (then appearing almost completely callose-thickened because of small size of lobes), lobes often breakingoff with age; sinus broadly rounded or flat Corolla 16-24 mm long and 4-4.5 mm in diameter, reddish-purple at very base, purple above, distal third short pilose; lobes triangular, obtuse, 12 mm long. Stamens 14.5-21 mm long;filaments densely short pilose or glabrate, alternately either 3 mm or 5-7.5 mm long, white; anthers including tubules alternately either 9.5-16.5 mm or 13-20 mm long, purplish-orange; thecae 3-6.5 mm long. Style 17-23 mm long. Berry not seen. Phenology: Flowering December-January, and July.

Discussion:
Cavendishia chiriquiensis is most closely related to C. panamensis and its distinctive characteristics are mentioned in the discussion of the latter taxon.
Type: Panama: Province of Chiriqui. Vicinity of Bajo Chorro, 1900 m , Woodson & Schery 688 (Holotype: NY! photo of type DUKE! isotype: MO!).
