Prunus microphylla is a species of Prunus found in the semi-arid regions of Mexico, able to thrive in areas that receive only 300 to 500 mm of rain annually.[3] Judging from its morphology, it is most closely related to Prunus minutiflora.[4] As its specific epithet suggests, its leaves are quite small, only 1 to 1.5 cm long. It is a dense shrub reaching about 1 m, with small white flowers. It was first described by Kunth as Amygdalus microphylla from the collections made by Humboldt during his voyage to the Americas from 1799 to 1804.[5]
