Description:Description - Scape + inflorescence (25-)50-100(-140) cm tall. Cincinni 3-17-flowered. Indument of inflorescence: rhachis, bracts, peduncles, bracteoles, pedicels, calyx, ovary, and capsule densely to sparsely covered with erect, simple hairs (ca 0.5 mm long), rarely mixed with some furcate hairs (to 0.2 mm long); sheaths of the inflorescence covered with appressed, simple, needle-like hairs (to 0.5 mm long) and towards the apex densely covered with mainly furcate hairs (less than 0.1 mm long). Bracts pale green. Peduncles 4-10(-12) mm long. Pedicels 3-10(-17) mm long. Corolla 13-16 mm long. Labellum 7-9 mm long and 5-9 mm wide. Style 14-17 mm long. Capsule ellipsoid to globose, 4-12(-14) X 4-9 mm.

Discussion:Renealmia occidentalis var occidentalis is closely related to R. floribunda and differs from that species by its striate leaf-sheaths, more numerously flowered cincinni and indument of the rhachis.

For the differences from the related R. mexicana see under that species.

A few specimens are aberrant in having a terminal instead of a basal inflorescence, namely, C. Wright 610 pp (NY), from Cuba; Lewis et al 2934 (MO, NY), from Panama; and Bartlett 12601 pp (MICH, US), from Guatemala. Two duplicates of the Bartlett collection (F, MICH), however, have a basal inflorescence.

I am not sure about the identity of Hoehne 1552 (R), from Tapirapoan, Rio Sepotuba, Mato Grosso, and Hoehne 732 (R), from Rio Jaurú, Mato Grosso, Brazil. They match R. occidentalis var occidentalis in most characters, but they are aberrant in having a completely glabrous inflorescence (as in central American var pacifica).
