Common Name The Lance-Like Lip Malaxis

Flower Size

Found in Chiriqui department of Panama and Cundinamarca, Cauc and Valle de Cauca department of Colombia in dense montane forest at elevations of 1300 to 1850 meters as a small to just medium sized, cool growing terrestrial with ovoid pseudobulb carrying 2, subopposite, ovate-oblong to ovate-lanceolate, obtuse to acuminate, truncate, sessile at the base leaves that blooms in the winter and again in the later summer on an erect, naked peduncle 6" [15 cm] long, rachis to .8" [2 cm] long, subumbellate, many flowered inflorescence and carrying pale small flowers.

"This species resembles tiny Malaxis sodiroi, as both have sessile abse leaves that easily separates them both from M brevis. From M sodiroi, M hastilabia has smaller leaf blades [2.8 x 2" [7 x 5 cm] vs 6.8 x 4.6" [17 x 11.5 cm], acuminate to more or less abruptly rostrate lip vs obtuse and basal auricles obliquely triangular vs obscure."
