Description
|
Small epiphytic shrubs to 1 m tall; stems terete, puberulous, becoming glabrous below. Leaves opposite; blades papyraceous, oblong-elliptical, mostly 4-8 cm long and 1.5-3.0 cm wide, the base short-cuneate, the margins distinctly remote- serrulate, the apex shortly acute, the upper surface sparsely punctate, the lower surface sparsely puberulous and densely glandular-punctate, the primary vein subpilose below, the secondary veins pinnate, not very prominent; petioles short, 1-2 mm long. Inflorescence a small corymbose panicle, 4.5 cm wide and 3.5 cm high, the branches puberulous and sparsely glanduliferous, the ultimate branches 1.5-6.0 mm long. Heads ca. 6 mm high and 1.5 mm wide with 8-9 florets; involucral bracts brown, ca. 12, subimbricate to eximbricate, in ca. 2 series, narrowly oblong with narrowly rounded tips, 1.5-2.5 mm long and ca. 0.4 mm wide, the outer surface sparsely puberulous and glanduliferous; receptacle glabrous; corolla lavender, ca. 4 mm long, narrowly funnelform, the inner surface glabrous, the outer surface puberulous and glanduliferous, the lobes very short- triangular; style base not enlarged. Achenes prismatic, ca. 1.7 mm long, puberulous and glanduliferous; carpopodium a distinct rim, the cells in 3-5 rows; pappus of ca. 32-35 slightly scabrous bristles with slightly enlarged tips, the apical cells acute.

Note
|
The species is related to N. eximia and occurs at the extreme eastern edge of the range of the latter. Neomirandea gracilis differs from N. eximia by the serrulate and nearly sessile oblong leaves, by the more sparing inflorescence, and by the numerous glands on the corolla lobes. Some material of N. eximia from Panama shows similar small inflorescences and some serrulation of the leaf margin which suggests introgression. A few specimens of N. allenii also show such tendencies and may indicate some past hybridization.
