Description:
Description - Epiphytic, thin, delicate subshrubs. Twigs subterete to angled, often sharply complantate, puberulous, the hairs simple and of two types, unicellular and eglandualr, or multicellular and glandular; mature stems subterete to angled, the bark fissured, grayish, glabrate, the hairs simple, unicellular and eglandular; prophylls 2, opposite, valvate, ovate, inconspicuous, 0.6 mm long, the apex acute. Leaves alternate, spirally arranged; petioles subterete, flattened above, ca. 1mm long, puberulous, the hairs simple, unicellular, and elgandular; blades subcoriaceous, ovate to ellipticovate, 8-12 x 5-6mm, the base rounded, the margine entire, eciliate, the apex bluntly acute, glabrous above, glaberscent beneath with scattered, simple, multicellular, reddish-brown, glandular hairs; venation 3 - plinerved, conspicuous only on the youngest leaves, otherwise only the midrib inconspicuoulsty raised on both surfaces. Axillary solitary flowers; bracts and floral undifferentiated, 4-5, narrowly triangular, 1-1.2 mm long, the margin ciliolate with simple, unicellular, eglandular hairs, the apex acute, glabrous on both surfaces; pedicels continuous with calyx, subterete, angles, ca. 1-1.6 cm long, glaberscent with few simple multicellular, glandular hairs; bracteoles 2, dinstinct, persistent, inserted towards base of pedicel, subopposite or opposite, triangular 1.0 -1.6 x 0.7 -0.8 mm, the margin ciliolate towards apex, the hairs simple, unicellular and elglandular, the apex acute. flowers 4- merous, diplostemonous. Caylx campanulate overall, strongly winged, 5.2 -6.5 mm long, glabrate, the hairs inconspicuous, scattered, simple and of two types, multicellular and glandular, or inicellular and elgandular, the aestivation valvate; tube obconic, 3.5 -4 mm long; limb 2-3 mm long; lobes deltate, 1.5 - 2x 2-2.5 mm, the margin eciliate, the apex acute; sinuses acute (V-shaped). Corolla bistratose, fleshy, red, urceolate, broadest below middle, 7.3 - 9(-10) mm long and 3.5 - 5 mm diam., glabrous within and without, the aestivation apparently valvate; lobes deltate, 0.5 -1.2 x 1-1.2 mm long, the apex acute. Stamens 8, equal, included, 6.3-6.5 mm long; filaments equal, distinct, linear, stright, 3 -3.5 mm long, densely puberulous in distal half on both surfaces, the hairs simple, unicellular and elgandular; anthers equal, 3.6 - 3.8 mm long; thecae 2-2.2mm long, minutely papillate, cells with polygonal shape; tubules 1.5 -1.8 mm long, smooth, dehiscing by interorse slits, ca. 1-1.4 mm long. Ovary 4-locular, placentation axile; style included, 8 mm long. Berry Unknown.

Discussion:
Phenology. - The type was flowering in March.
Etymology. - Th em is tóeles ia woytko wskii is named to honor Felix Woytkowski (1892- 1966), a Polish botanists who collected in Peru.Themistoclesia woytkowskii is characterized by its small (8-12 x 5-6 mm) and bluntly acute leaves, solitary flowers, pedicels that are continuous with the calyx and conspicuously long (> 1 cm), and winged calyces. The differences between this species and T geniculata, another species with continuous calyx and 4-merous corollas, are discussed above.
