Distribution:— Peru and Colombia. In Peru it is found in the department of Junín. It is a species of which only isolated records are known from Peru and Colombia, however, it is to be expected that there are many other intermediate populations, being a species with a wide range of distribution.

Notes:— Epidendrum physopus is recognized by the small plants, 12–20 cm tall, the leaves 1.2–3 cm, linear-lanceolate, the sepals 6–8 mm long, and the lip 3-lobed with the lateral lobes obliquely semi-ovate and the mid-lobe narrowly triangular with the margin erose. In the Soratae subgroup few species have a 3-lobed lip; E. fruticulus and E. chrysomyristicum have clearly 3-lobed lips, but the plants are around 2 m tall, the flowers larger, the sepals 10–13 mm long, and the margins of the lip entire.

Conservation Status:— DD. Data deficient.As most orchids, listed in CITES appendix II, and categorized as VU at the national level.
