Matucana rebutiiflora is a species of cactus in the subfamily Cactoideae, native to Peru.[1]

Description

Matucana rebutiiflora displays a spherical shape in a medium-green color, reaching a diameter of up to 7 cm and forms compact clusters of stems with a substantial taproot. As the plant matures, it develops 9-12 ribs, and their number increases over time. These ribs are segmented into well-defined tubercles, separated by a noticeable horizontal groove. Areoles are circular with whitish felt and measuring 0.7cm in diameter, are spaced approximately 1.2cm apart. The plant features up to six radial spines, each extending up to 2 cm, accompanied by a central spine reaching a length of up to 2.5cm. Spines are initially brownish and later fading to white, are mostly straight with a slight curve.

The flower of Matucana rebutiiflora measures 8.0 cm in length, opens to a width of 6.5cm, and displays a red hue with a hint of violet, featuring a prominent white base on the inside. The fruit, approximately 1.7cm long and 1.3cm wide, starts off green and undergoes a darkening process as it ages.[2]
