Description

Small epiphytic shrubs 1-2 m tall; stems terete, faintly striate, glabrous. Leaves opposite; blades fleshy, elliptical, to 8 cm long and 3 cm wide, the base cuneate, the margins usually entire, the apex sharply acuminate, the surfaces glabrous, without evident glandular punctations, the lower surface somewhat paler, the primary vein distinct, the secondary veins usually totally obscure, strongly ascending; petioles to 1.2 cm long, glabrous. Inflorescence a loose corymbose panicle, to 12 cm high and 15 cm wide, the ultimate branches ca. 9-14 mm long, densely puberulous. Heads ca. 1 cm high with ca. 9 florets; involucral bracts purple-tinged, ca. 15, subimbricate, in ca. 3 series, 1.5-5.0 mm long, broadly lanceolate with narrowly rounded to subacute tips, the outer surface glabrate; receptacle glabrous; corolla lavender, ca. 4 mm long, narrowly funnelform, glabrous or with a few minute hairs on lobes, the lobes as long as wide to somewhat longer; style base not enlarged, glabrous. Achenes prismatic, 2.5-3.0 mm long, glabrous or with a few bristles; carpopodium a narrow rim, the cells in 3-5 series; pappus of ca. 40 slender, slightly scabrous bristles, ca. 4.5 mm long, the apical cells acute.

Distribution

known only from Costa Rica and Panama.

Note
|
The species is common in parts of Costa Rica but seems comparatively rare and variable in Panama. Some Panamanian plants have a few bristles on the achene unlike populations in Costa Rica, and specimens from farthest east tend to have sparser inflorescences and more reduced, slightly serrulate juvenile or secondary leaves. The latter plants may indicate some introgression with the related N. gracilis of central Panama.
