Ariocarpus trigonus or better known as Landmine Flowers is a species of flowering plant in the family Cactaceae, native to Mexico (the states of Tamaulipas and Nuevo León).[2]

Description

[edit]

Ariocarpus trigonus grows as a solitary plant, reaching up to 30 cm in diameter, though older plants can form groups. The plant features numerous shiny brownish-gray-green warts that are curved, acutely triangular on one side, and sharply keeled backward to the base. These warts are 3 to 8 cm long and 1.5 to 2.5 cm wide at the base, with barely visible areoles on their slightly broken tips.

The plant has a very thick beet-like root. Its numerous yellowish flowers, up to 50 mm long and wide, form a wreath around the woolly crown.[3][4]

Taxonomy

[edit]

First described as Anhalonium trigonum by Frédéric Albert Constantin Weber in 1893, the species was placed in the genus Ariocarpus by Karl Moritz Schumann in 1898.[5] The specific epithet "trigonus" is Greek for "triangular," referring to the shape of the warts.[6]
