Vegetative characteristics

Mimosa aculeaticarpa is a scrubby, thicket-forming shrub that usually reaches heights of about 1 meter, but occasionally doubles in size. The bark of the branches is hairy. The branches are covered with bent thorns that easily get caught in clothing.

The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The bi-pinnate has a variable number of small elongated leaflets.

Generative characteristics

Many flowers are grouped together in a spherical, head-shaped inflorescence . The hermaphrodite flowers are white or pale pink in color.

The flat legume is up to 4 centimeters long and tears open when ripe. It has thorns bent back at the edges.

Occurrence

Mimosa aculeaticarpa is distributed from central to southern Arizona, southern New Mexico, western to central Texas, and northern Mexico.

Mimosa aculeaticarpa grows in higher areas. Mimosa aculeaticarpa occurs sporadically in oak , oak, pine and evergreen forests as well as in pinyon ^a- juniper forests. It also grows with other shrubs in grassland and shrub-steppe communities. It grows on mesas , stony slopes, and gravel deposits. Mimosa aculeaticarpa is commonly found in the chaparral and spreads into the deserts and semi-arid areas. The cause could be that the fruits are eaten by the cattle and spread well hidden in the dung, where they find a nutrient-rich environment to germinate. Mimosa aculeaticarpa is fire tolerant and quickly sprouts again after bush fires. In the highland areas of western Texas, the juniper Juniperus pinchotii is used as a breeding plant for the seedlings. These benefit from the shade and litter of the junipers, which seem to offer a favorable microclimate .

^a Pinyon is the collective name for the pine species Pinus monophylla and Pinus edulis .
