Opuntia abjecta ease. "O. abjecta" is a small plant with radiating branches, a subshrub. Retrorsely barbed spines are reddish-brown as they develop; they mature to pale white (not bright white). Zero to three spines are produced by terminal cladodes. Generally, the spines of "O. abjecta" are shorter than 4 cm. The flower bud of "O. ajbjecta" is rounded (not acute). "O. abjecta" has teardrop-shaped leaves. The seeds are about 4 mm in diameter. Opuntia abjecta Opuntia abjecta is a short cactus, perhaps to 15(25) cm tall. It occurs in the Florida Keys and has been conflated with "O. triacantha". Recent work shows
Opuntia ficus-indica the Mediterranean basin. Under those hedges and adjacent areas soil physical properties, nitrogen and organic matter are considerably improved. Structural stability of the soil is enhanced, runoff and erosion are reduced, while water storage capacity and permeability is enhanced. Prickly pear plantations also have a positive impact on plant growth of other species by improving severe environmental conditions which facilitate colonization and development of herbaceous species. Opuntia ficus-indica is being advantageously used in Tunisia and Algeria to slow and direct sand movement and enhance the restoration of vegetative cover, minimizing deterioration of built terraces with its deep and strong rooting
