Opuntia gosseliniana Opuntia gosseliniana Opuntia gosseliniana, commonly known as the violet pricklypear, is a species of cactus that is native to Pima County, Arizona in the United States and Baja California, Chihuahua, and Sonora in Mexico. Like most prickly pears, the pads are flat. Unlike most prickly pears, they have a violet, pink, or red tinge, hence the name. The cactus reaches mature heights of one to five feet and blooms either yellow or red. Different authorities disagree on the division of plants into "Opuntia chlorotica", "Opuntia violacea", "Opuntia gosseliniana", "Opuntia macrocentra", and perhaps others. To complicate the issue, there are numerous
Plant functional type key parameters are defined, such as fecundity, competitiveness, resorption (rate at which plant decays and returns nutrients to the soil after death), etc.; the value of each parameter is determined or inferred from observable characteristics such as plant height, leaf area, etc. Climatologists and ecologists struggle to determine which minimal set of plant characteristics best model the actual responses of the biosphere in response to climate changes. 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
