Description edit
Matucana krahnii usually grows solitary and only rarely sprouts with flattened spherical to short cylindrical, grey-green shoots and reaches heights of 10 to 14 centimeters with a diameter of 5 to 10 centimeters. There are 10 to 18 low and broad, conically bumpy ribs present. The mostly curved, pliable, yellowish-brown spines turn gray with age. The one to four central spines are 2 to 15 centimeters and 8 to 18 radial spines 1.5 to 5 centimeters long.
The straight to slightly curved, crimson flowers are up to 8.5 centimeters long and have a diameter of 7 centimeters. The spherical, green fruits reach a diameter of up to 1 centimeter.[3]
Distribution edit
Matucana krahnii is found in the Peruvian Amazon region north of the town of Balsas on steep sandstone slopes at altitudes of 1650 to 1750 meters.
Taxonomy edit
The first description as Borzicactus krahnii was in 1979 by John Donald Donald.[4] The specific epithet krahnii honors the German cactus collector Wolfgang Krahn (* 1939). Rob Bregman placed the species in the genus Matucana in 1986.
