 Epiphytic, caespitose, ascending, erect herb to 4.5 cm tall. Roots fibrous, flexuous, glabrous, to 1 mm in diameter. Stem abbreviated, terete, to 3.5–9.0 mm long, completely concealed by a papyraceous, subancipitous, acute sheaths to 3 mm long. Leaf narrowly linear, up to 35 × 1.5–3.0 mm, minutely and irregularly emarginate at apex, the mid-vein protruding abaxially into a small apicule, gradually tapering toward the base into a deeply conduplicate petiole, subcoriaceous. Inflorescence borne laterally from the base of the leaf, without an annulus, successively single flowered, up to 4.0– 4.5 cm long, glandular; peduncle terete, to 3.0 cm long, with 1 distant, glandular, terete bract, 3 mm long.

Ovary subclavate, with low, irregularly crenulate crests, 1.5–2.0 mm long, green. Flowers up to 4, reddish-orange, developed in succession. Sepals fleshy, densely glandulose on the outer surface; dorsal sepal lanceolate-elliptic, 3-veined, acute, the base semi-hyaline, flushed with orange along the veins, the distal two thirds reddish-orange with occasional transparent spots, 7.5–9.0 × 2.0–3.0 mm; lateral sepals narrowly elliptic-oblanceolate, subfalcate, 3-veined, 7.5–9.0 × 3.5–4.5 mm, connate for about three quarters of their length, the base saccate, membranaceous-hyaline, the apex acute. Petals reddish-orange, small, ligulate-falcate, 3.5–4.0 × 1.7–1.9 mm, 2-veined. Lip reddish-orange, small, longitudinally arched-convex in natural position, thinly articulate with the column foot by a hyaline claw, sagittate to oblong when expanded, obtuse, 4.5 × 1.0 mm, provided with a pair of acute, sub-trapezoid lateral lobes from just below to just above the middle, margin dentate-erose, especially apically. Column dark-red, arched, terete and slender at the base, 3.5 mm long without the foot, provided with membranous wings serrulate along the margins, the apex prolonged into a deeply cucullate, lacerate clinandrium; column foot, stout, fleshy, 1.0 mm long. Anther cap deeply cucullate, ovate, crested, 2-celled. Pollinia 2, obovate-complanate, minutely hooked at the base. * NOTE: Description based on AK 2945 and IC1111.

 Etymology: —The name alludes to the very long, thin leaves, which is reminiscent of species of the fern genus Vittaria.   
 Distribution: —Known from Mexico, El Salvador, Costa Rica and Panama. In Costa Rica and Panama it is found mostly in the Caribbean lowlands, from 400 to 1,190 m elevation. In Mexico and El Salvador it is found at higher elevations, from 1,000 to 1,400 m (Fig. 6).   
 Notes: — Aside from a sterile fragment of the plant and an accompanying sketch of the type kept at AMES, nothing else remains of the type material of Specklinia vittariifolia. The specimen was supposedly collected in San Jerónimo, Moravia, Costa Rica. We were unable to locate any such plants in the area during a series of field trips, and doubt it did indeed come from there. It is more likely that Wercklé actually collected this plant a few km North-East along the same road, where this species is abundant. There are more collections from Wercklé that, like this species, are typically found on the warm and humid Caribbean watershed, but were allegedly collected in San Jerónimo, a dryer and colder locality in the Central Valley (Pupulin 2010). The illustration of the type and description are not very specific to any of the species of this group; however, the plant fragment and illustration clearly depict a species with long and narrow leaves and an inflorescence that barely reaches the length of the leaf.   
 Specklinia vittariifolia is locally abundant in certain areas in the Costa Rican Caribbean at mid to low elevations. It has been confused with the similar S. glandulosa in herbaria and living collections, however, it can be easily distinguished by the long leaves and relatively short inflorescences which in living material rarely exceed the leaf. The flower is conspicuously downward twisted, and its segments noticeably spreading. Although frequently appearing single flowered, the species can produce up to 4 flowers in tight succession on a single inflorescence, however only one is developed at a time. The flowers are relatively large, with sepals exceeding 7.5 mm long and a lip of 4 mm long, with a pair of conspicuous sub-trapezoid lateral lobes.   
 The herbarium sheet of Roy Lent ’s number 1762 kept at CR represents a mix of both S. alajuelensis and S. vittariifolia. We cannot be certain if both were collected together or if they come from different localities. However, the locality corresponds perfectly with that of other material of S. alajuelensis, and we have therefore chosen to give that material the number Lent 1762a. The two CR specimens with long, narrow leaves, and all of those kept at SEL are S. vittariifolia, and are given the number Lent 1762b, with unknown locality.
