Epiphytic shrub, mature branches pendent, terete, smooth, glabrous, tan to reddish brown when dry; immature branches subterete, bluntly angled, striate, glabrous or rarely sparsely short pilose, provided with tiny, reddish, caducous glands. Leaves elliptic, lanceolate, or ovate lanceolate, (3-) 6-10 cm long, (2-) 2.5-3.5 cm wide, basally rounded or cuneate, apically long acuminate or caudate acuminate, brownish green to tan when dry, glabrous; 3(5-) -pli- nerved, the midrib impressed and prominent above or somewhat plane distally, raised and conspicuous beneath, the lateral nerves slightly raised on both the surfaces or rarely impressed above, conspicuous only above; petiole subterete, flattened adaxially, rugose, (3-)4.5-9 mm long, 0.5-1.5 mm in diameter, glabrous or densely short pilose, becoming glabrate, reddish brown. Inflorescence usually with all parts viscid, 6-10-flowered; rachis subterete or bluntly angled, glabrous, (2-)2.5-3.5(-4.5) cm long, and 1-1.5 mm in diameter with scattered red, clavate glands; floral bracts glabrous, oblong, apically rounded, basally slightly clasping, 6-10 mm long, 3-6 mm wide; pedicels striate, ribbed, glabrous, 10-19 mm long, 0.5-1 mm in diameter, with glands as on the rachis; bracteoles strongly nerved, somewhat striate, broadly ovate to semiorbicular, apically rounded and apiculate, the apiculum callose thickened, basally auriculate, 2.5-4.5 mm long and broad. Flowers with the calyx glabrous, (3-)4.5-7.5 mm long, red, the tube smooth or rugose, 5-angled, 1-2(-3) mm long, broadly enlarged basally with the enlarge- ment perpendicular to the calyx axis, the limb cylindric or somewhat spreading, smooth or rugose, (2-) 2.5-4 (-6.5) mm long including the lobes, the lobes triangular, (0.5-)1-1.5 mm long, erect after anthesis, completely callose thick- ened and glandular, sinuses obtuse or broadly rounded and almost flat; corolla slightly narrowed at the throat, the distal portion often curving upwards, 29-32 mm long, 3-7 mm in diameter, glabrous, blue (fide Mori & Dressler 7776); sta- mens ca. 26.5 mm long, the filaments glabrous, alternately 3.5 mm and 8 mm long, the anthers including tubules alternately 25 and 20 mm long, the thecae 6-7.5 mm long; style ca. 31 mm long.

Note

Cavendishia melastomoides var. coloradensis is endemic to Cerro Colorado, Chiriqul Province. It differs from the other two varieties of C. melastomoides (var. melastomoides and var. albiflora both from Costa Rica) primarily in its broadly ovate to semiorbicular bracteoles which have callose-thickened, apicu- late tips.
