THE CACTACEAE. 
Type locality: Mexico. 
Distribution: Northern Mexico. 
This species has, until now, been known only from the type collection of Karwinsky 
which should be at Munich. In 1912 Dr. Rose obtained a specimen from Dr. Radlkofer, 
but without label, which we now suspect is a part of the original material of Karwinsky. 
Senor Octavio Solis wrote us that in 1919 he obtained specimens of this plant at Barre- 
tillas, Nuevo Leon, and also at Ciudad Guerrero, Tamaulipas. The four specimens which 
he took back to the City of Mexico soon died. In May 1921 Senor Solis sent one of the 
specimens from Ciudad Guerrero which had been collected by Professor Francisco Contreras 
and we have been able to confirm his identification. Senor Solis says that the plant is 
known as peyote.

Subglobose or short-cvlindric, up to 25 cm. high; ribs 7 or S, high, acute; areoles distant, 2 to 
3 cm. apart; spines several, more or less flattened, weak, hardly pungent, brown, 3 to 5 cm. long; 
flowers 6 to 7 cm. long, widely spreading when in full bloom; outer perianth-segments reddish, 
gradually passing into the lemon-yellow inner perianth-segments with papery tips, orange at base, 
spatulate, acute or cuspidate at the apex, entire or more or less toothed; stamens numerous, attached 
over all the inner surface of the flower-tube; style slender, cream-colored; stigma-lobes linear, 
somewhat spreading, 5 to 9, cream-colored; seeds 2.5 mm. broad, shining. 
Type locality: La Rinconada, Mexico. 
Distribution: Northern Mexico. 
Dr. C. A. Purpus writes that this plant is found on the hills of lime and slate formation 
south of Parras. It is very scarce and grows associated with Lophophora williamsii and 
Ariocarpus furfuraceus. He believes that the variety minor is specifically distinct; this he 
found at Pena and Villareal, Coahuila, and also on Cerro de la Bola and in the Sierra de la 
Paila.
