partial sun Warm Cool LATE Spring EARLIER Summer

Common Name The Heart-Shaped Stigma Habenaria

Flower Size .4" [1 cm]

Found in Disticto Federal and Goias statese of Brazil in dry grassy field (campo limpo) and grass-herb-subshrub field (campo sujo) vegetation, over deep, clay latosols or dry gray soil associated with rock outcrops at elevations around 1000 meters as a medium to just giant sized, warm to cool growing terrestrial with 10 to 14, adpressed to the stem, linear, narrow, largest towards the middle grading smaller above leaves that blooms in the late spring and earlier summer on a terminal, erect, 4 to 9.6" [10 to 24 cm] long, loose to congested, few to many flowered inflorescence with ovate, as long as the ovary floral bracts.

"The new species is similar to H. crucifera , but H. cardiostigmatica has smaller flowers (dorsal sepal .14 to .16" [3.5 to 4 mm] x .12 [3 mm] vs. .2 to .24" x .16 to .22" [5 to 6 x 4 to 5.5 mm in H. crucifera), a linear spur (vs. clavate), and a distinct column structure with the space between the stigma lobes heart-shaped (vs. circular) and the stigma lobes uncinate (vs. straight, not uncinate). In column morphology H. cardiostigmatica is similar to H. mystacina, also from section Nudae. In both species the rostellum midlobe is slender, with an acute apex, the rostellum anns are slender, narrow, the two functional stigma lobes are uncinate and the space between them, which gives access to the spur, is heart-shaped. However, H. mystacina has deeply bipartite petals, the lateral segments of the petals and lip are densely pubescent and the species seems to be related to other taxa with hairy segments such as H. pubidactyla."
