Roots fasciculate, about 0.5–1.0 mm wide. Rhizome 0.9–1.1 mm wide, branched. Secondary stem 2.2–5.1 × 0.4–0.7 mm, cylindrical, unifoliate, concealed by one white to gray, close-fitting, membranaceous sheath, 2.5–5.0 mm long, acute or obtuse apex, striate, entire margin. Leaf 5.0–19.0 × 1.2–3.0 mm, oblanceolate to elliptic, pale green, coriaceous, glabrous, acute apex, rarely minutely tridenticulate, attenuate to obtuse base, entire margin. Inflorescence terminal, congested, fasciculate, erect; peduncle and rachis inconspicuous; floral bracts about 1.0– 1.1 mm long, amplexicaul, membranaceous, acute to acuminate apex, entire margin. Flowers 1–4, reddish maroon (according to the collector), these opening successively; pedicellate ovary 1.2–1.5 × 0.1–0.3 mm; dorsal sepal 3.0–3.5 × 0.8–1.3 mm, free, lanceolate, membranaceous, acute apex, entire margin, 3-nerved; lateral sepals 3.0–3.5 × 0.6–1.0 mm, connate up to ¼ from base, lanceolate, sub-falcate, membranaceous, acute apex, entire margin, 3-nerved, forming a small mentum with the column foot; petals 1.8–2.6 × 0.3–0.6 mm, free, narrow elliptic, sub-falcate, membranaceous, acute to rounded apex, entire margin, 1-nerved; lip 1.5–2.0 × 0.3–0.5 mm, free, oblong, rounded apex, with two basal appendages, ciliate margin from the base up to the middle, entirely ciliate or sometimes not ciliate, papillose, 3-nerved, articulated with the column foot; column about 1.0– 1.3 mm long, broadly winged, clinandrium 5-dentate, obtuse apex, entire margin, column foot about 0.2 mm long. Fruit 2.5–3.0 × 1.2–1.5 mm, obovoid, glabrous.</p> <p>Distribution and Ecology: —This species is known only from the type locality, in the central Brazilian Amazon, state of Amazonas. The vegetation in the area is characterized by moist tropical lowland forest, locally called terra firme forest (Lima et al. 2008). The flowering period is poorly known, but based on the specimens cited, flowers can be observed from February to July.</p> <p>Etymology: —This new species is named on behalf of the area of occurrence, Brazilian Amazon basin.</p> <p>Morphological affinities: — Anathallis amazonica is morphologically related to species placed in Panmorphia by Luer. The new species has a subrepent habit like A. holstii and A. polygonoides. Leaf shape appears to vary: the leaves on the mature branches are oblanceolate like A. sertularioides, while on the immature branches they are elliptic as is found in A. holstii and A. polygonoides. The inflorescences have an inconspicuous peduncle and the flowers appear to arise from the same point like A. holstii and A. polygonoides. In A. sertularioides, the inflorescence is long pedunculate. The flowers on A. amazonica have narrow elliptic petals like A. sertularioides, but A. polygonoides and A. holstii have broadly elliptic petals. The lip of A. amazonica is oblong and ciliate from the base up to the middle, entirely ciliate or sometimes not ciliate. However, the three related species have a slightly trilobed to clearly trilobed lip with an entire margin (Table 1).</p> <p>Additional specimens examined (paratypes): — BRAZIL.
