General Information

Plants 0.4-3 m tall. Rhizomes 3-10 mm thick. Sheaths striate, 4-10 mm wide, glabrous or sometimes towards the ligule and near the margins covered with furcate and stellate prickles (to 0.1 mm long). Ligule 1-2 mm long, glabrous or covered with furcate to stellate prickles (to 0.1 mm long) and/or simple, appressed hairs (0.1-0.3 mm long). Petiole 0-12 mm long, hairy like the sheaths. Lamina narrowly elliptic, acute or shortly acuminate at the apex (acumen 5-10 mm long), cuneate at the base, 640 cm long, (1.5-) 2-7(-8) cm wide (the uppermost leaves often strongly reduced: 3-26 X 0.5-7 cm), glabrous on both sides. Inflorescence a terminal thyrse 3-17 cm long and 1-8 cm wide, with (1-) 2-4(-5)-flowered cincinni, rhachis pink to red, 1-2(-3) mm thick. Indument of inflorescence: sheaths, rhachis, peduncles, and pedicels glabrous or densely covered with furcate (and plurifurcate) hairs, and mostly much fewer simple hairs (both hair types 0.1-0.4 mm long), bracts, bracteofes, and calyx sparsely so at their base, ovary and capsule glabrous to sparsely hairy, corolla glabrous (for the exceptional indument of Ekman 214 see the discussion). Bracts red, pinkish-red, or scarlet, membranous, rather long persistent, ovate to triangular, acute to obtuse at the apex, 8-30(40) mm long, 3-10(-15) mm wide (the lower, sterile ones 40-100 X 6-15 mm). Peduncles 2-10(-12) mm long. Bracteole red 4-10 (-13) mm long. Pedicels 2-15(-20) mm long. Calyx (bright) red, tubular to slightly turbinate, 5-11 (-13) mm long, 3-6 mm wide, the lobes depressed-ovate, 1-2 mm long, 24 mm wide. Corolla white, 14-25 mm long, the tube 6-12 mm long, the lobes 6-13 mm long, 3-5 mm wide. Labellum white (according to Wright margins and lateral staminodes slightly tinged with purple), 5-8 mm long and wide when spread out, glabrous, the limb more or less transversally elliptic in outline, 3.5-6 mm long, 5-8 mm wide, the middle lobe obscurely divided into two broadly ovate-deltate to ovate-triangular lobules 0.5-1 mm long, basal claw 1-3 mm long, 1.54 mm wide, lateral staminodes 0.8-1.3 mm long, 0.3-0.5 mm wide. Anther red, 4-6 mm long, 1.5-3 mm wide, glabrous. Style (13-) 16-23 mm long. Nectarial glands multilobulate, 1-2 mm long, completely surrounding the style base. Ovary red. Capsule red, maturing black, globose to ellipsoid, 5-10 X 5-8(-10) mm, its wall ca 0.1 mm thick when dry, 5-25 seeded, seeds 1.5-3 X 2-3.5 mm.
