34 THE CACTACEAE. 
Plants low, almost buried in the ground; ribs usually 13, low, somewhat tuberculate; young 
areoles bearing 6 to 8 rather stout, short, spreading spines; old areoles spineless; flowers about 5 cm. 
broad, magenta-colored; inner perianth-segments spatulate, with an ovate acute tip; filaments rose- 
colored; areoles of the ovary and flower-tube bearing brown spines and cobwebby wool. 
Type locality: Mexico. 
Distribution: San Luis Potosi, Mexico. 
This plant has recently been introduced into Europe in great quantities. It is rather 
inconspicuous, but has very pretty flowers. 
Echinopsts pulchella rosea (Labouret, Monogr. Cact. 292. 1853) was given as a synonym 
of the species.
