Its common names include pancake prickly pear, flapjack prickly pear and dollarjoint prickly pear. This cactus is bluish-green and manifests a bushy to erect form that may attain a height of two meters or more. Some analysis of the prehistoric range of "O. chlorotica" has been conducted by studies in the Waterman Mountains of Arizona; these pollen core analyses indicate that this cactus species was present in northern Arizona in late
Plant functional type Plant functional type Plant functional types (PFTs) is a system used by climatologists to classify plants according to their physical, phylogenetic and phenological characteristics as part of an overall effort to develop a vegetation model for use in land use studies and climate models. PFTs provide a finer level of modeling than biomes, which represent gross areas such as desert, savannah, deciduous forest. In creating a PFT model, areas as small as 1 km are modeled by defining the predominant plant type for that area, interpreted from satellite data or other means. For each plant functional type, a number of
