Rapicactus booleanus is a species of plant in the family Cactaceae.
Description
Rapicactus booleanus grows solitarily with a tuberous root connected to the stem by a narrow neck 1-5 cm long. The grey-green stems are spherical, obovate to turbinate, narrowing at the collar, and measure 2.5-4.5 cm tall and 2.5-5.5 cm in diameter. The hard, spirally arranged tubercles are closely set, 4-angled, rhomboid, somewhat flattened and almost truncated above, and somewhat horny or keeled below. There are 2 erect central spines, whitish with dark brown tips, measuring 12-21 mm long. Around 18-20 radial spines are white and measure 3-17 mm long. Flowers are pale to dark magenta with darker midstripes, blooming on summer days, and are 2 cm long and 2.5 cm in diameter. The fruits are dark green to purple, 7 mm long and 6 mm in diameter, and split open when ripe.[1]
