Echinocereus fasciculatus, commonly known as pinkflower hedgehog cactus, is a clumping cactus (Cactaceae) with brilliant magenta flowers and long spines found in the Sonoran Desert.[2]: 90 

Description

Echinocereus fasciculatus forms loose groups consisting of five to 20 shoots. The green cylindrical to elongated shoots are 16 to 45 centimeters long and have a diameter of 4 to 7.5 centimeters. The shoot surface is not completely covered by the spines. There are eight to 18 ribs that are not clearly tuberculated. The two to four straight, light-colored central spines have a darker tip and are 2.5 to 7.5 centimeters long. One of them stands out. The eleven to 13 spreading, straight, whitish or grayish marginal spines are 1.2 to 2 centimeters long.

The broadly funnel-shaped flowers are magenta to reddish purple. They appear in the upper half of the shoots, are 5 to 6.2 centimeters long and reach the same diameter. The spherical, fleshy, initially green fruits later turn red.[3]

Distribution

Echinocereus fasciculatus is distributed in the United States in the states of New Mexico and Arizona and in the neighboring Mexican state of Sonora.

Taxonomy

The first description as Mammillaria fasciculata by Benjamin Daydon Jackson was published in 1895.[4] The epithet fasciculatus comes from Latin, means 'densely packed together' and refers to the cluster-forming reed-like shoots of the species. Wolfgang Blum and Michael Lange introduced the species as a subspecies to the species Echinocereus engelmannii in 1998. Nomenclature synonyms are Cactus fasciculatus (Engelm. ex B.D.Jacks.) Kuntze (1891, nom. illegal ICBN article 53.1), Neomammillaria fasciculata (Engelm. ex B.D.Jacks.) Britton & Rose (1923), Echinocereus engelmannii subsp. fasciculatus (Engelm. ex B.D.Jacks.) W.Blum & Mich.Lange (1998) and Echinocereus fendleri var. fasciculatus (Engelm. ex B.D.Jacks.) N.P.Taylor (1985).
