Description

Opuntia stricta is an erect, much-branched succulent shrub, usually 1–3 m tall, forming dense clumps. Stems consist of flattened, green, obovate to elliptic cladodes (pads) measuring 10–25 cm long. Cladodes bear clusters of spines and numerous minute barbed glochids. Leaves are minute, fleshy, and short-lived, soon falling from young cladodes. Flowers are solitary, large, showy, and bright yellow, sometimes becoming orange with age. Fruits are fleshy, ovoid to pear-shaped berries, green when immature and purplish-red to reddish-purple at maturity, containing numerous flattened seeds.

Taxonomic Notes

Opuntia stricta is readily distinguished by its erect shrubby habit, flattened spiny cladodes, bright yellow flowers, and reddish-purple fleshy fruits. It is closely related to other prickly pears but differs in its growth form and fruit characteristics. In many regions outside its native range, it is regarded as an invasive species due to its rapid vegetative and seed dispersal. The accepted name follows Flora of Pakistan, Plants of the World Online (POWO), and World Flora Online (WFO).
