Common Name The Twinned Sobralia [refers to the usually paired flowers]

Flower Size 3.6" [9 cm]

Found in Costa Rica in very wet premontane forests at elevations around 1400 meters as a small to giant sized, cool growing terrestrial with dark purplish green mottled with pale green stems carrying elliptic to broadly elliptic, acuminate, apiculate, plicate, 7 to 9 raised veined beneath leaves that blooms in the fall on a terminal, ellipsoid, 1.4 to 1.6" [3.5 to cm] long, subtended by smaller foliar bracts, successively single, few flowered inflorescence carrying ephemeral flowers.

"The flowers of Sobralia geminata resemble those of S. chrysostoma, but they are consistently smaller, and they also have brownish spots or streaks on the lip, and some white near the apex. Sobralia chrysostoma frequently has dark purplish spots on the stems and sheaths, while the stems of S. geminata are consistently more heavily spotted than any other species in our area. The form of the stigma is quite variable in this species. The stigma varies a good deal in size, often being cuplike, as in most other species, or it may be straight, tongue-like, and subparallel with the column axis. In this latter pattern, the pollen probably germinates on the upper side of the stigma, thus accomplishing selfpollination." Dressler & Bogarin 2010
