Fig. 5 View FIGURE 5 , 8 View FIGURE 8 .

Epiphytic, subrepent-ascending, erect herb to 30 cm tall. Roots fibrous, flexuous, glabrous, to 1.5 mm in diameter. Stem abbreviated, terete-cylindric, to 2.2 cm long, monophyllous, completely concealed by a papyraceous, subancipitous, acute sheath to 3.5 cm long, eventually disintegrating into fibrous remains. Leaf narrowly obovate-oblanceolate, 17.0–29.0× 3.2–3.9 cm, minutely and irregularly emarginate at apex, the midvein protruding abaxially into a small apicule, gradually tapering toward the base into a deeply conduplicate petiole with strongly ancipitous margins, subcoriaceous. Inflorescence born laterally from the apex of the stem, without an annulus, a lax, distichous, successively 4–7-flowered raceme, up to 40 cm long; peduncle flattened, ancipitous, to 30 cm long, with 4–5 distant, amplectent, ancipitous, subacute bracts, 7–8 mm long. Floral bracts infundibuliform, broadly ovate, abaxially ancipitous, acute to subacuminate, 10× 8 mm. Pedicel cylindric, glabrous, 13–15 mm long, persistent. Ovary subclavate, with low, irregularly crenulate crests, 4–5 mm long, green. Flowers with dark orange-red sepals and petals, lip red, column yellow. Sepals fleshy, densely papillose on the inner surface except at base, margins thickened-revolute; dorsal sepal lanceolate-elliptic, triveined, acute, the base semi-hyaline, flushed with orange along veins, the distal twothirds densely papillose, the revolute margins glabrous, 20× 7 mm; lateral sepals narrowly elliptic-oblanceolate, subfalcate, triveined, 19–20× 5 mm, connate for about one-quarter to one-third of their length, the base saccate, membranaceous-hyaline, the apex acute, gently deflexed at the middle, the midvein strongly carinate abaxially. Petals small, ligulate-falcate, truncate, porrect, 6.0–7.0×1.0– 1.5 mm, univeined, papillose-thickened toward the concave apex, the labellar margin provided with coarse papillae arranged in two rows, the outer margin thickened. Lip small, longitudinally arched-convex in natural position, thinly articulate with the column foot by a hyaline claw, narrowly elliptic-lanceolate when expanded, obtuse, the apex reflexed, appearing minutely retuse, the clawed base thickened, transversely minutely gibberose, 8.0–9.0×2.0– 2.5 mm, provided with 2 slender keels, fringed-lacerate at the base, gently converging from the base of the lamina to near the apex, then spreading. Column arched, terete-slender at the base, 6.0– 6.5 mm long without the foot, provided with broad membranous wings serrulate along the margins, at the apex forming a deeply cucullate, sharply lacerate clinandrium; column foot forward-projecting, stout, fleshy, incurved, 2.0– 2.5 mm long. Anther cap deeply cucullate, ovate, 2-celled. Pollinia 2, obovate-complanate, minutely hooked at the base. Fruit not seen.

Distribution:— Relatively frequent in southern Costa Rica and western Panama, where it grows on the Talamanca-Chiriqui range, at 1750–2500 m. Also reported from the Colombian northern Pacific coast at sea level, perhaps ranging to Ecuador ( Fig. 9 View FIGURE 9 ).

Notes:— Specklinia remotiflora is apparently common along the Pacific watershed of southern Talamanca Mountains in Costa Rica and adjacent Panama. Even though we are not aware of any record in central and western Panama, the distribution of the species is likely continuous southward at least to the Pacific coastal range of Baudó in northern Colombia, where populations morphologically similar to S. remotiflora were documented by Misas Urreta (2006). It is noteworthy, however, that Colombian plants were found growing at sea level, whereas in Costa Rica and Panama S. remotiflora is exclusively known from submontane and montane wet forests at 1750-2500 m. Plants in cultivation at Ecuagenera (Pupulin, pers. obs. 2009), supposedly collected in Ecuador but without specific locality data, also correspond to this species.

The repent habit, lax inflorescence, and subcampanulate, orange flowers provided with obtuse, nonapiculate petals easily distinguish S. remotiflora from S. endotrachys and S. spectabilis , to which it is most similar. It has non-mucronate petals like S. pfavii , but the latter has a caespitose habit (vs. repent in S. remotiflora ), congested inflorescence (vs. lax), yellow flowers with red petals (vs. orange), and oblong, entire column wings (vs. triangular, denticulate).
