Taxonomic notes

Description

Distribution

It is a native to Mexico but has spread and become naturalized in Florida.[1]

Ecology

Habitat

Habitats include grasslands, open woodlands, rangelands, pastures, waste areas, disturbed sites, roadsides, and near creeks.[2] It is adapted to life in the desert, by modified transpiration techniques and producing food with photosynthetic tissue in the bark.[3] Soil types include sandy loam, sand, clay, and loam. [4] [5]

If growing in an over-irrigated spot, P. aculeata is susceptible to powdery mildew and root rot.[4]

Phenology

Flowers and fruits March through August. [5]

Seed dispersal

Seeds are dispersed by birds and other animals.[2]

Seed bank and germination

Seeds have a tegumentary dormancy which allows them to last a long time in seed banks until germination conditions are favorable. [6]
