Description:
Species Description - Terrestrial or epiphytic shrub with branches to 1.5 m long; stems terete, weakly striate, glabrous or weakly puberulent, yellowish-brown, provided with few scattered, black globular, sessile glands ca. 0.3 mm in diam. Leaves lanceolate, (3-)4.5-10.7 X (0.8-)1.3-3 cm, basally tapering and acute or obtuse, apically long-acuminate, margins revolute, glabrous above and glabrous or weakly hirsute along midrib beneath with hairs 0.5-0.7 mm long, upper surface provided with pustular glands similar to those on stems except these ca. 0.2 mm in diam.; 5-7-plinerved from near base or with inner pair of lateral nerves arising 2-3 cm above base, only the midrib or the midrib, lateral nerves, and reticulate veinlets strongly impressed and conspicuous above, only the midrib or midrib and lateral nerves strongly raised beneath causing leaves to be bullate; petioles terete, rugose, glabrous or puberulent, to 5 mm long and 1.8 mm in diam., with scattered glands similar to those of the leaves. Inflorescence 20-30-flowered, encircled at base by numerous oblong-oblanceolate sterile bracts similar to floral bracts; rachis subterete, bluntly angled, 9.5-12 cm long and 1.5-3 mm diam., glabrous but with translucent globular glands to 0.3 mm in diam. along length but especially near base; floral bracts at anthesis spreading at an angle of nearly 90° from rachis and with tips reflexed, substriate, oblong to oblong-lanceolate, 20-35 X 5-8 mm, apically acute or obtuse, glabrous or with a tuft of hairs with each hair ca. 0.3 mm long, pink to red when fresh, marginally bearing 8-10 green, scattered spherical to oblong subsessile glands ca. 0.1-0.2 mm in diam.; pedicels 4-8 mm long, glabrous but with globular glands clustered at distal tip; bracteoles located near or just below middle of pedicel, ovate-oblong, obtuse, 2-4 mm long, marginally with spherical to oblong glands similar to those of floral bracts. Flowers: calyx glabrous, 6-7 mm long; hypanthium cylindric, weakly 10-ribbed, ca. 1.5-2 mm long and 3 mm diam., basally weakly apophysate, reddish to yellowish-green with a mauve hue when fresh, provided with numerous spherical glands ca. 0.2-0.3 mm in diam. around apophysis margin; limb campanulate, smooth, ca. 4.5-5 mm long and 7 mm diam. at tip; lobes ovate-triangular, acute, ca. 1.5-2 mm long and 3 mm broad, erect (?) after anthesis, each side flanked by an oblong callose gland ca. 1.5-1.75 mm long, these nearly contiguous or slightly connate at tip of lobe; sinus rounded or acute sometimes partially obscured by two spherical or short-oblong glands 0.1-0.3 mm in diam.; corolla immature but at least 20 mm long, glabrous, red to deep wine-red in bud when fresh; stamens immature, but filaments and anthers alternately long and short; filaments densely puberulent medially. Berry not seen.

Discussion:
Cavendishia albopicata needs more study before its morphology is completely understood. Since the species was described (Luteyn, 1980), two additional collections have been seen which are reluctantly placed here. They are from central Antioquia and show the following differences from the type which is itself florally immature: leaves larger (8-10 X 2.5-3 cm not 3-8 X 0.8-2 cm), glabrous (not hirsute along midrib beneath), bullate with 5-7 nerves strongly impressed above and raised beneath (not 5-plinerved with only the midrib conspicuously impressed above and slightly raised beneath), inner lateral nerves arising 2-3 cm above the base (not arising at the base); floral bracts apically acute or rounded, and glabrous (not acuminate with a tuft of hairs at the apex); and corollas white with pinkish apices fide Scolnik et al. 19An493 (not totally red when in bud). These variations may only be local in nature, and since the gland types are basically similar in all collections, I am placing the Antioquia specimens in albopicata.Within series Lactiviscidae, C. albopicata is most similar to C. panamensis, C. fortunensis, and C. pseudostenophylla. The differences between these species are given in the key and discussed more fully under C. fortunensis.
