Matucana krahnii is a species of Matucana found in Peru.[2]
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.
