terrain. Rocky soils.
OBS:Palm solitary. Tallest specimen to 30-40 cm tall. LEAVES 3-4 in
crown, spirally arranged and spreading. Leaf sheath ca. 2-4 an long,
pseudopetiole (leaf sheath plus petiole) is 4-9 cm long, with the true

sheath, adaxially channeled and abaxially rounded. Leaf rachis 17.5-49
cm long. 7-13 pairs of leaflets which are distributed regularly along the
midrib. Basal leaflets 8.5-43 x 0.1-0.5 cm, middle leaflets 31-54 x 0.8-1.1
cm, and apical leaflets 14-35 x 0.2-0.4 cm. Tranverse veins raised and
