Description:
Species Description - Stemless, very rarely short-stemmed, generally solitary plants of understory, sometimes with a few basal shoots, the stem, when developed, to 50 cm X 3-4 cm, unarmed, the internodes very short. Leaves 5-12, erect; sheath 15-35 cm long, brownish green, usually armed with black spines 0.5-5 cm long; petiole 0.3-1.4 m long, brown-scurfy, terete; rachis 0.8-1.8 m long, either unarmed or sparsely armed with erect, black spines 3-8 cm long; blade pinnate, with 12-20 pinnae per side; pinnae oblanceolate, slightly sigmoid, long-acuminate, sometimes obliquely bifid at apex, 15-45 X 2.5-5 cm, oriented in several planes and clearly borne in 5-8, rather widely spaced, clusters of 2-5; segments of apical pair wider (6-10 cm), often split into 3-5 teeth at tip. Inflorescence single, interfoliar, short, erect; peduncle green, glabrous or setose, slightly curved, 10-15 cm long; prophyll flattened, 10-14 cm long, covered with appressed, black setae; peduncular bract 20-30 cm long, brown, densely covered with slender, brown or black prickles 2-12 mm long, early decaying at base; rachis 2-5 cm long, bearing few to many rachillae 7- 10 cm long. Fruits globose, setose, 8-12 mm diam., orange to bright red at maturity. Fl (Feb-Jul), fr (Sep-Jan)
