    General Description
    Stem cespitose 1 .8-3.0 m tall, stems 4 -6, 1.2-1.5 cm diam., internodes usually spiny. Leaves 5-8, sheaths to 16.0 cm long., covered with black spines; petiole glabrous or with a short whitish pubescence, 11.2-16.0 (-25.5) cm long; spines yellow with the extremes dark brownish tips, (0.5-) 1.6-3.5 cm long, the basal portion of the petiole with more abundant, shorter spines. Lamina rachis (33.0-) 41.0-54.0 cm long, bearing a whitish pubescence and spines abaxially as on the petiole, pinnate, the pinnae (4-) 7-10 per side, irregularly arranged in groups of 2-3 and spreading in different planes; terminal pinnae larger than the middle ones, 17.0-31.0 (-39.5) long, and 5.5-14.5 cm wide, apex apiculate; middle pinnae sigmoid and convex, 15.0-22.5 (-28.7) cm long, and 4.2-5.1 (-7.0) cm wide, whitish pubescence on both sides, with (1-) 2 prominent main veins, apex strongly aristate, 3.5-7.0 cm long, and bent downward. Inflorescence infrafoliar, peduncle 5.0-8.0 cm long, 5.0 mm wide, recurved at anthesis, spinulose on the distal part, prophyll 8.0 cm long, peduncular bract 11.0-14.6 cm long, covered with short blackish-brown spines, rachis short (0.7-) 1.4-1.7 cm long, rachillae 8-12, 3.2-5.0 cm long, covered with glandular hairs; triads irregularly arranged. Staminate flowers not seen. Pistillate flowers sessile, sepals connate, to 1.5 mm long, glabrous; corolla tubular, 2.1-2.8 mm long, glabrous and striate (when dry). Fruits obovate, to 1.2 cm long and 1.0 cm diam. the stigmatic residue prominent, orange-red when mature, glabrous and striate, corolla evident in fruit, irregularly divided, to 3 mm long.
    Habitat
    Known only from the type locality on the Pacific Coast of Costa Rica, on the Fila Tinamaste, Perez Zeledon; between 900-1050 m. The forest in this area has been severely fragmented, but some remnants are located on top of the Fila Tinamaste, a rocky formation that arises abruptly in the landscape. The climatic conditions on the top of the Fila form a certain type of microclimate, which is very humid and characteristic of a cloud forest. The palm community in the remnants is mainly composed of understory species, such as: Asterogyne martiana, Bactris herrerana, B. dianeura, Chamaedorea pinnatifrons, C. pumila, Geonoma ferruginea and Synechanthus warscewiczii.
