It produces yellow to cream flowers about 1 to 1 1/2 inches long and wide during February through March. The lower central spines are hooked at the tip, like a fishhook. The fruit is fleshy and green, ripening to pink or pinkish- brown by late spring or early summer. The seeds are black.

- It is found on the western Edwards Plateau in Bandera, Edwards, Kerr, Kimble, Kinney, Real, Uvalde, and Val Verde Counties.
