Hermaphrodite plant, succulent, cactiform, with stems up to 0.8(1.5) m in height, robust, upright, of a pale green-greyish colour; stems are lignified at the base and they stop growing after flowering. Stems with 4 wings (or angles), narrow, with concave angles in between them, which gives the stem an \u201cH\u201d shape. On these angles, there are recurved-deltoid teeth. Leaves ovate and promptly caducous. Flowers arranged in umbelliform cymes, sessile at the end of stems and forming dense globose heads with 20-80 flowers, that open \u00b1 at the same time. Flowers with pedicels of 4-6 cm; with corollas of 15-20 mm in diameter, rotate, with 5 ovate-triangular lobes, black-purplish, with numerous pits of beige color, without striped bands, without cilia at the apex. Corona double and pentamerous, with external lobes divided into 2 small recurved horns, and internal lobes as long as the anthers. Follicle (10-15 \u00d7 0.4-0.6), smooth, linear, slightly curved and attenuate at the apex.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-13263","species","type-species","status-publish","hentry"],"acf":[],"yoast_head":"\n
