Description

Matucana pujupatii occasionally grows with spherical to ovoid, gray-green to blue-green shoots that branch slightly from the base and reaches heights of up to 15 centimeters with diameters of 10 centimeters. There are ten to twelve straight, wide ribs that are tuberculated. The curved, flexible, brown thorns are yellowish at their base and turn gray with age. The one or two central spines - which are occasionally missing - are up to 5 centimeters long, and the six to nine marginal spines are 0.5 to 2 centimeters long.

The slightly curved, crimson flowers are 6 to 7 centimeters long and 4 to 5 centimeters in diameter. The spherical to egg-shaped, somewhat purple-green fruits reach a diameter of up to 10 millimeters.

Distribution

Matucana pujupatii is widespread in the Peruvian Amazon and Cajamarca regions at altitudes of 1000 to 1500 meters.[2]

Taxonomy

The first description as Borzicactus madisoniorum var. pujupatii was made in 1971 by John Donald Donald and Alfred Bernhard Lau.[3] The specific epithet pujupatii honors Shawintu Pujupat Dagses, a Peruvian boy who accompanied Alfred Bernhard Lau during his tour in Peru. Rob Bregman elevated the variety to the rank of a species in 1988. A synonym is Matucana madisoniorum var. pujupatii (Donald & A.B.Lau) G.D.Rowley (1971).[4]
