Opuntia anahuacensis Opuntia anahuacensis Opuntia anahuacensis is a cactus species in the "Opuntia" genus and a member of the Opuntioideae. It grows along the Gulf Coast of Texas, and perhaps northern Mexico. The plants are short, perhaps 1- or 2-ft tall, but they are wide. Some thickets may be 20- to 40-ft across and composed of multiple plants. The fruit is purplish. The cladodes are uniquely shaped, obovate with a neck. The original description claimed the plants were yellowish green, but they may be green or rarely blue-green. As with any largish "Opuntia" in the USA, "O. anahuacensis" has been mistaken for
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
