Pyrus bourgaeana hermaphrodite flowers are white, rarely tinted pink, 2–3 cm diameter, and have five petals.

[4] Fruits are non-dehiscent globose pomes weighing ~ 9.5 g, with green or brown skin inconspicuous to birds, copious lenticels permitting scent to emanate, and pulp high in fiber.

[5][6] Within the Iberian Peninsula, P. bourgaeana distribution is very fragmented with trees occurring at low densities in small patches of Mediterranean scrubland that are isolated from each other by towns, cultivations, etc.

First, by creating the initial template on which post-dispersal processes act, its seed dispersers like foxes and badgers can be partially responsible for P. bourgaena aggregation.

Second, dispersal limitation sometimes leads to seedling establishment beneath mother trees, resulting in an aggregated patterning.

This is a likely possibility since a fraction of the fruit fallen beneath adult trees are not taken by mammals or are partially depulped by rabbits, without dispersing the seeds.

In the Doñana National Park (Southwestern Spain), P. bourgaeana experience heavy browsing by red deer Cervus elaphus and sprouts of a range of sizes emerge beneath some trees.
