Opuntia bentonii (less inclinded to narrow at the base). "O. bentonii" plants have fewer spines than "O. lindheimeri", zero to 3 (often only 1 or 2). One important difference is that the stigmas of "O. bentonii" flowers are yellow and not green as in "O. lindheimeri." Another individual feature of "O. bentonii" is that the veins are often visible between areoles. Opuntia bentonii Opuntia bentonii was proposed by some botanists to be a synonym of "Opuntia stricta". However, "O. bentonii", which grows in Texas, is separate and distinct from "O. stricta." "O. bentonii" was clearly described by Griffiths in 1911. Along with
