LATE EARLIER

Common Name The Tiwinza Epidendrum [A town in Ecuador near where the type was collected]

Flower Size .6" [1.5 cm]

Found in southern Ecuador near the Peruvian border on the Cordillera del Condor at elevations around 1800 meters as a small to medium sized, cool growing epiphyte with simple, cane-like, terete, thin, straight stems carrying 7, all along the apical 2/3'ds of the stem, sub-erect, sub-coriaceous, narrowly elliptic, acuminate, minutely apiculate, margin entire leaves that blooms in the late summer and earlier fall on a terminal, racemose, short, arching, occuring only once, peduncle short, .48" [1.2 cm] long, terete, thin, with 2 basal bracts similar to the floral bracts but longer, rachis 1" [2.5 cm] long, 1.46" [3.6 cm] long overall, successively 1 or 2, to 6 flowered inflorescence with about twice as long as the ovary, gradually shorter above, triangular, lanceolate, acuminate floral bracts and carrying resupinate, pale green flowers.

"Epidendrum tiwinzaense belongs to the GROUP Bicirrhatum which is characterized by the caespitose habit, simple, canelike stems, short, arching, pluriracemose, subcapitate inflorescence, narrowly spathulate petals, 3-lobed lip, midlobe usually ending in cirrhate lobes and unequal, laterally compressed pollinia, with the inner pair smaller. The new species has pale green flowers with the column and lip cream-colored, sepals some .28" [7 mm] long, lateral lobes of the lip subquadrate, midlobe terminating in a pair of cirrhate lobes. It closely resembles Epidendrum bicirrhatum which has smaller, opaque, pale cream-orange flowers, the sepals and petals green at the base, the tips of the calli keels lavender, and the column white at the base, cream-yellow above. Epidendrum hugomedinae Hágsater & Dodson is vegetatively similar, but has very attractive, fragrant, snow-white flowers with the keels of the lip tinged violet and the obcuneate midlobe formed by two, somewhat divergent, rounded lobes. The Bolivian E. ophidion Dodson & Vásquez is quite similar to the first, but has successive, white flowers with·three purple lines on the disc, pustulate sepals .24 to .32" [6 to 8 mm] long, and the dolabriform lateral lobes with a crenulate margin. Epidendrum brachyblastum Hágsater & Dodson has narrow lateral lobes of the lip, shorter apical cirrhose appendages and deep green flowers with the lip and apical half of the column snow white."
