Distribution and habitat

A. martianus grows only in Oaxaca, Mexico, in cloud forests and oak forests at elevations of 1,500–2,200 m (4,900–7,200 ft). It is locally abundant within its range. [1] [3]

Description

Disocactus martianus grows creeping, occasionally forming lithophytic with aerial roots. It is a species of fleshy, cylindrical suspended or creeping cactus with stems up to 1.5 meters long and up to 2.5 centimeters thick, sometimes with aerial roots, with 8 to 10 slightly wart-shaped ribs; 3 or 4 central pale brown spines up to 12 mm long and 6 to 20 radial spines are light yellowish and only 5 to 7 millimeters long. The bright red flowers are diurnal and produced in summer, 10 to 12 centimeters in diameter and a length of 5 to 7 centimeters. The flowers stay open for a couple of days. They are followed by globose fruits of green color and 2 cm in diameter. It is viviparous. [4]
