Common Name The Resembling Epidendrum platystomum Epidendrum
Flower Size .4" [1 cm]
Found in Costa Rica in cloud forest remnants at elevations around 2400 meters as a medium to large sized, cold growing epiphyte with branching, cane-like, terete, flexuous, main branch yellow, thick and tall, secondary branches much smaller and tertiary or floral branches very short and carrying numerous on the main stem, 5 to 6 on the secondary and 2 to 3 on the tertiary, blade linear-lanceolate, obliquely bilobed and articulate below into the base leaves that blooms in the later summer on a terminal, racemose, distichous, arching, occuring only once, short, zigzag inflorescence arising on the secondary or tertiary stems with much longer than the ovary, conduplicate, ovate, acute, floral bracts and carrying 3 to 6, simultaneously opening, non-resupinate flowers.
"Epidendrum platystomoides belongs to the GROUP Ramosum which is characterized by the monopodial, branching stems, the spike-like, distichous inflorescence, and the single callus, and the SUBGROUP Rugosum which has a branching habit with few-flowered inflorescence from short, secondary stems, the leaf-sheaths rugose. The species is recognized by the tall, thick, flexuous main stems with long 4,4 to 5.8" [11 to 14.5 cm], narrow leaves and rugose leaf sheaths, the short, distichous Inflorescence with 3 to 6 small, white flowers with .115 to .124"[2.9 to 3.1 mm] long sepals and the triangular-hastate lip which is about as ilde as it is long, bicallose, the calli laminar, very small, and the column arching throughout, short, wlth a funnel-shaped, blunt apex. It is similar to Epidendrum platystomum Hágsater & L.Sánchez which has shorter leaves on the main stem 2 to 3.2" [5 to 8 cm], smaller sepals .092 to .108" [2.3 to 2.7 mm] long, ana a widely, deeply triangular-hastate lip, with the apex thickened and minutely papillose, ecallose, and the column arched at the base only. Epidendrum sanchol Ames has larger flowers, sepals .18 to .26" [4.5 to 6.5 mm long and 5-veined, lanceolate, acute, and a proportionately narrower triangular-hastate, acuminate lip and the union with the column straight and narrow. Epidendrum trachythece Schltr has smaller flowers, sepals .06 to .14" [1.5-3.5 mm] long, 5 to 7 veined, the lip is reniform-apiculate, bicallose, the calli prominent, wide, and reaching the middle of the disc. Epidendrum nutantirhachis Ames & C.Schweinf., grows in the same general area, and has somewhat shorter leaves on the main stem to 3.8" [9.5 cm], larger flowers with the sepals .24 to .44" [6 to 11 mm] long, and a triangular-cordate lip with a prominent fleshy callus and high central keel."
