Common Name The Lipped Sarcoglottis
Flower Size
Found in French Guiana as a medium sized, hot growing terrestrial with 4, in a basal rosette, erect, sublinear, white streaked with brown, ellitical, acute to subacute, channeled below into the subpetiolate base leaves that blooms in the spring on an erect, terminal, peduncle to 12" [30 cm] long, provided with 6, glabrous, longer than the internodes sheathing bracts, rachis to 3.2" [8 cm] long, 7 to 11 flowered inflorescence with baslly pubescent , sometimes reflexed at the apex, , longer than the ovary floral bracts carrying diurnally lemon scented, white flowers
"Confused with !Sarcoglottis acaulis but differs in the rather short pseudopetiolate base leaves to 1.84" [4.6 cm] long versus 1.6 to 8" [4 to 20 cm] long, white streaeked with brown instead of greenish white leaves, the leaves elliptic, acute to subacute, broader versus elliptic, oval to lanceolate-oval, acute, narrower, the lateral sepals distinctly narrower, the epichile different in shape, broadly oval, subacute apically, pleated blade with a wavy margin versus most often transversely elliptic, often apiculate at the apex, and the margin most often toothed, eroded, S labiosa has a callus with 2 parallel veins extending to the middle of the epichile versus most often a narrowly v-shaped, arising slightly above the apex of the disc and extending almost to the apex of the epichile. S labiosa has a spathulate, lanceolate, acute clinandrium at the apex vesus a clinadrium that is oblong, slightly widening towards the apex, obtuse to subacute, sometimes dentate at the apex." S labiosa cannot be fully separated from the Panamanian Sarcoglottis hunteriana or S powelii and they all may be conspecific, as they are only separated by the sheathing bracts being longer than the internodes, versus shorter to more or less the same length in the other 2, the subacute apex of the lateral sepals versus acute or acuminate, the petals slightly narrower and a strongly pleated epichile of the lip versus smooth. I S labiosa the callus consists of 2 parallel veins originating in the middle part towards the apex of the hypochile versus 2 v-shaped veins originating on the margins towards the apex of the hypochile."
