LATE EARLY
Common Name The Heart Shaped Tongue Sigmatostalix
Flower Size .4" [1 cm]
Found in Costa Rica in lower montane forests at elevations around 1050 meters as a mini-miniature sized, warm growing epiphyte with elliptic-ovate, compressed pseudobulbs enveloped basally by 3 to 5, distichous, green flushed with purple-brown, some foliaceous sheaths carrying subcoriaceous, linear-ligulate, obliquely bilobulate apically, narrowing below into the conduplicate, petiolate base leaf that blooms in the late fall and early winter on a lateral, erect-spreading, slender, apparently secund, much longer than the leaves, to 8.8" [22 cm] long, successively several flowered inflorescence with flowers subtended by papyraceous bracts and lanceolate, acute, scarious, almost as long as the pedicel floral bracts.
"Sigmatostalix cardioglossa has the smallest habit among Mesoamerican species of the S. picta group. The cylindric claw of the lip lacking a central channel, the tri-mammillate callus at the base of the lip, and especially the cordate lamina without any lateral lobe, easily distinguish this species from its Costa Rican relatives."
