"Epidendrum pseudavicula belongs to the GROUP Aquaticum which is characterized by the usually monopodial, branching habit, the distichous, erect to arching-nutant inflorescence, flowers fleshy, and the disc of the lip and/or nectary often pilose. The species is recognized by the small plants, .28 to 8" [7 to 20 cm] tall, leaves narrowly ovate to oblong-lanceolate, .4 to 3.2" x .24 to .72" [1.0 to 8.0 x 0.6 to 1.8 cm], yellow-green flowers, sepals .224 to .24" [5.6 to 6.0 mm] long, petals linear, .2 to .213" x .3 to .32" [5.0 to 5.3 x 0.75 to 0.8 mm], calli small, thin, parallel. Epidendrum aquaticum Lindl. has similar sized plants, but the leaves are lanceolate, .52 to 2.04" x .16 to .24" [1.3 to 5.1 x 0.4 to 0.6 cm], flower green, sepals ca. .2" [5 mm] long, and the lip with the base truncate. Epidendrum carnosum Lindl. has much taller plants, to 50" [125 cm] tall, leaves lanceolate, 1.6 to 3.44" x .24 to .52" [4 to 8.6 x 0.6 to 1.3 cm], flowers yellow or yellow-green, sepals .36 to .4" [9 to 10 mm] long, petals .32 to .36" x .06 to .1" [8 to 9 x 1.5 to 2.5 mm], lanceolate-rhombic, and the lip with a single callus, apically bilobed. Epidendrum dendrobioides Thunb. has linear-lanceolate leaves 1.4 to 2.4" x .2 to .32" [3.5 to 6.0 x 0.5 to 0.8 cm], yellow flowers, sepals .24 to .3" [6.0 to 7.5 mm] long, petals .22 to .24" x .04 to .048" [5.5 to 6 x 1.0 to 1.2 mm], the calli thin, convergent towards the apex, forming a “Y” with a narrow mid-rib in between the calli."
