Closely related to Annona emarginata, and considered to be no more than a form of that species by some botanists[
This name is not universally accepted. We are following the treatment in the online Flora do Brasil 2012, but some other treatments accept the genus Rollinia, in which case the correct name for this species would be Rollinia rugulosa Schltdl.[
Rollinia rugulosa Schltdl.
Annona rugulosa is a deciduous tree with a dense, wide crown; it can grow 7 - 14 metres tall[
]. The bole can be 30 - 40cm in diameter, usually branching from quite low down[
The tree is harvested from the wild for local use of its edible fruit and wood.
S. America - south and east Brazil.
Higher elevation forests, often in association with Araucarias in the south of its range, and often in degraded forest patches and clearings[

Fruit - raw[
]. A sweet, acidic pulp[
]. The subglobose fruit is about 6cm in diameter[
A fast-growing pioneer species within its native range, providing food for the native fauna. It is suitable for use in reforestation projects[
Heartwood and sapwood are not clearly differentiated. The wood is light in weight, of low durability when exposed to the elements[
]. It is only used for low value items such boxes[
The wood is used for fuel[
Seed - it has a very hard outer layer and germinates much more easily if scarified[
]. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Sow the seeds in a nursery seedbed or in individual containers in a lightly shaded position. Germination rates of scarified seeds can above 90%, with the seeds sprouting within 25 - 35 days[
