Stelis sessilis Luer & Toscano 2012 SECTION Stelis

TYPE Drawing by Luer & Toscano


Common Name The Sessile Stelis [refers to the rounded, sessile base of the leaf]

Flower Size .12" [5 mm]

Found in Sao Paulo state of Brazil without locational data as a medium sized, caespitose epiphyte with erect, stout ramicauls enveloped by a spotted tubular sheath below the middle and 2 others at the base and carrying an erect, coriaceous, elliptical, obtuse apically, rounded below into the sessle base leaf that blooms in the late summer and early fall on 2, erect, arising through a slender spathe at the apex of the ramicaul, subcongested, distichous, peduncle 1.2" [3 cm] long, to 3.2" [8 cm] long overall with most flowers open simultaneously, several flowered inflorescence with thin, tubular, almost as long as the ovary floral bracts and carrying rose colored flowers. .

"The leaf with a rounded, sessile base is apparently unique in the Brazilian species of Stelis, and not commonly seen in the numerous species of Stelis in the Andes. Sessile leaves that are acuminate or cuneate into the base without a petiole are not uncommon. The ramicaul of this species is about four times as long as the leaf in the only specimen known. Two inflorescences slightly shorter than the leaf produce many flowers simultaneously." Luer & T 2012
