"Epidendrum porquerense belongs to the GROUP Tipuloideum which is characterized by the caespitose, sympodial habit, 1 to 2 apical leaves on a short stem, grass-like to thickened and fleshy to semi-terete, a short, racemose inflorscence, the flowers green, petals narrower than the sepals, and deeply 3-lobed lip. Epidendrum porquerense is recognzied by the short thickened, fusiform pseudobulb covered by 3 to 5 non-foliar sheaths, 1 to 2 apical leaves coriaceous, sub-terete, canaliculate, flowers lime-green, concolor to more or less tinged purple-rose, petals shorter than the sepals, and the lip deeply 3-lobed, the margins of lateral lobes erose, mid-lobe sub-quadrate, apex triangular, acute with the margin involute. Epidendrum tipuloideum Lindl. has a fusiform, thin, terete pseudobulb, 1 to 2 grass-like leaves, petals longer, and flowers brownish white. Epidendrum recurvatum Lindl. has ensiform, mucronate, leaves, inflorescence usually paniculate, much longer than the leaves, and a lip entire, cordiform, the apex of the mid-lobe slighlty emarginate. Epidendrum costanense Hágsater & Carnevali has grass-like leaves, peduncle with 2 basal spathes, somewhat inflated, 4 to 20 flowers, lateral sepals slightly aristate, petal margins erose, and a lip cordate, never 3-lobed, margins minutely erose, apex of mid-lobe acute.Epidendrum brassavoliforme Lehm & Kraenzl has very thin stems, a single coriaceous, nearly terete leaf, greenish pink flowers, sepals 3-veined, and a lip 3-lobed, mid-lobe longer and narrower, acute, disc with a mid-rib reaching the apical sinus, lateral lobes cordate, much smaller, apex elongate and acute."
