The snake's head restrepiella (Restrepiella ophiocephala) is a species of orchid and the only species of the genus Restrepiella. The orchid is known from Mexico to Costa Rica, occurring in damp forests alongside rivers at low altitude (40-1,600 m). It is morphologically similar to Restrepia, but differs in lacking hairlike attachments on a mobile lip and having four pollinia instead of two.
The epithet ophiocephala is derived from the Greek words ophis (snake) and cephalos' (head).
It grows from a short, creeping rhizome as a tufted, robust epiphyte to a length between 8 and 35 cm. The stout, cylindrical stem is erect and about 15 cm long and has a tubular bract. The fleshy, oblanceolate leaves are 8 to 18 cm long and have a short petiole.
The tiny single flowers have a length of about 2 cm. They grow from the base of the leaves, one at a time, on up to four clustered inflorescences. They have a pale yellowish-brown color, dotted with dull purple spots. The outer surface is downy. The obovate, dorsal sepal is erect, while the lateral sepals are fused (synsepals) with a small split at their apex. The elliptic petals are much shorter and with ciliated margins. The fleshy lip is tongue-shaped.
The flowers are in bloom from winter to spring and are strongly scented.
