The
type specimen was collected near
Yaracuy, Venezuela at an altitude of 100 meters.
Peperomia croizatiana is an epiphytic
herb, and it forms dense, tufted clumps. The
stems are erect, 2 to 3 millimeters in diameter, with dark magenta spots and covered in dense, spreading hairs. The
leaves are nearly stalkless or have very short
petioles only 1.5 to 2 millimeters long. Most leaves are arranged oppositely in pairs, but the uppermost leaves often grow in whorls of three. The leaf blades are thick and leathery, strongly concave or cup-shaped, and pale green on the underside. They are lance-shaped or narrowly elliptic, with a blunt tip, measuring 15 to 26 millimeters long and 4 to 8 millimeters wide, while the lower leaves are shorter. The leaves are covered abundantly with resinous spots and are mostly hairless, except near the edges where there are tiny, flattened, pressed-in hairs. The leaf margins are curved inward. The flower
spikes are erect, solitary, and grow at the tips of the stems. They are pale green, up to 10 centimeters long, and 2 millimeters in diameter. The
peduncle, is pale green and 1.5 to 2 centimeters long. The central spike axis is hairless. The floral
bracts are nearly round, pressed flat against the spike, abundantly covered with resinous spots, and hairless. The
stigma is located at the tip and is stalkless. This species is related to
P. ocmarana and
P. rhombea. From
P. ocmarana, it differs by having tufted stems with spreading hairs, strongly curved-in and concave leaves that are not notched at the tip, and a short flower stalk. From
P. rhombea, it differs by having a more rounded leaf tip, narrower leaves, a densely tufted growth habit, and shorter spaces between leaves with noticeably spreading hairs. ==Taxonomy and naming==
