Opuntia basilaris bristles; this indicates that the species does vary a lot in its exterior. "Opuntia basilaris" contains 0.01% mescaline and 4-hydroxy-3-5-dimethoxyphenethylamine. The Cahuilla Native Americans used beavertail as a food staple. The buds were cooked or steamed, and then were eaten or stored. The large seeds were ground up to be eaten as mush.

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
