Description:
Species Description - Compact, somewhat scandent, epiphytic shrub with stems 1-2 dm long; mature branches terete or subterete, striate, glabrous, brownish, old leafless nodes prominently raised; twigs subterete, bluntly angled, striate, densely pilose. Leaves elliptic, 10-15 X 7-8.5 mm, rounded at both ends, margin thickened, glabrous, weakly nerved with apparently 3-4 nerves per side, midrib weakly impressed through proximal half otherwise plane above and weakly raised but obscure beneath, lateral veins obscure on both surfaces; petiole subterete, conspicuously broadly channelled above, rugose, 1-3 mm long and 0.5-1.4 mm diam., pilose, glabrate. Inflorescence composed of a single flower enveloped by a series of glabrous, marginally glandular-fimbriate bracts attached to a short peduncle 0.5-1.5 mm long; rachis none; the first series of inflorescence (sterile) bracts ovate to 3 mm long and 4 mm broad, the next 7-10 bracts (floral bracts) oblong, 8-15 x 7 mm; pedicel ca. 0.5 mm long; bracteoles ± basal, oblong, 1.5 X 0.5 mm, glabrous, marginally glandular-fimbriate. Flowers: calyx glabrous, ca. 4.3 mm long; hypanthium obconic or campanulate, rugose, ca. 1.5-2 mm long; limb campanulate or erecto-patent, ca. 2.5-2.8 mm long; lobes triangular, acute, 1.2 mm long, marginally densely glandular-fimbriate with the fimbriae laterally fusing; sinus narrowly obtuse; corolla cylindric, slightly zygomorphic, ca. 20 mm long and 4-5 mm diam., seemingly membranaceous the proximal half and coriaceous the distal half, red but distally yellow (fide label data), lobes oblong, obtuse, ca. 2 mm long; stamens ca. 16 mm long; filaments pilose ventrally but the long filaments also bearing few hairs on dorsal surface, alternately ca. 1.5 mm and 2.5 mm long; anthers subequal, 14-15 mm long; thecae 3-4 mm long; style subequal to corolla. Berry not seen.

Discussion:
Cavendishia sophoclesioides is characterized by its scandent habit, small elliptic leaves, and solitary essentially sessile flowers enveloped by a series of bracts. Its calyx lobe glands are notable in that the fimbriae are almost totally fused being laterally “cemented” by their exudate, although the individual fimbriae are weakly discernible. This condition exemplifies the ultimate step in fusion of fimbriae into continuous marginal glands discussed in MORPHOLOGY. Notable, too, are the stamens in which the anthers are nearly equal in length, the thecae being short with respect to the tubules, and the dehiscence clefts short relative to most species of Cavendishia.Cavendishia sophoclesioides is most closely related to C. uniflora, being similar in reduced 1-flowered inflorescences encircled by numerous persistent bracts, gland types found on floral bracts, bracteoles, calyx lobe margins, and slightly zygomorphic corollas. The major differences between them are summarized in Table IV.Summary of differences between Cavendishia sophoclesioides and uniflora.
