Description

Epidendrum sculptum has hanging cane-like stems, covered in imbricating sheaths. On the part of the stem away from the roots, these sheaths bear alternate, oblong leaves, up to 5 cm long, which are two-lobed at the distal end. The inflorescence is so short that the three flowers appear to be sessile on the apex of the stem. According to Dodson & Dodson, 1989, the non-resupinate

Resupination generally means being upside-down, supine, facing upward. The word is derived from the Latin. In a biological context, the concept is commonly expressed with the adjectives "resupinate" or "non-resupinate."-Examples in green plants:...
