Echinocereus pamanesii is a species of cactus native to Mexico.[2]
Description
[edit]Echinocereus pamanesii usually grows solitary.[3] The dark green cylindrical shoots are up to 35 cm (14 in) long and have a diameter of 8 cm (3.1 in) with twelve to 19 ribs.[3] The up to two protruding to spreading central spines, which can also be missing, are brownish.[3] They are up to 1.7 cm (0.67 in) long.[3] The nine to twelve yellowish to whitish radial spines lie on the surface of the shoot and are up to 1 cm (0.39 in) long.[3]
The funnel-shaped flowers are deep pink and have a whitish throat.[3] They appear well below the shoot tips, are up to 9 centimeters long and reach the same diameter.[3] The egg-shaped brownish green fruits are woolly and have thorns.[3][4]
Distribution
[edit]Echinocereus pamanesii is found in the Mexican state of Zacatecas.[2]
Taxonomy
[edit]The first description by Alfred Bernhard Lau was published in 1981.[5] The specific epithet "pamanesii" honors the Mexican politician General Fernando Pámanes Escobedo, a former governor of the state of Zacatecas, who supported Alfred Bernhard Lau on his travels.[5]
