The Mountain Soursop (Annona montana Macfad.), is grown to a limited extent. It resembles the soursop tree in growth, but the leaf is larger. The mountain soursop grows well on dry soils and may have merit as a rootstock for other annonas.

Fruiting Habits:
The fruit (fig. 7) is nearly spherical, and the yellowish skin is sparsely covered with short prickles. The yellowish pulp is similar to the soursop in flavor but is inferior to that fruit. Variations among seedling trees indicate that higher quality strains might be selected.
