Psidium guajava L.
Family: Myrtaceae · Genus: Psidium
Native tropical American fruit tree, common in Brazilian syntropic agroforestry systems. Pasini lists it in the high stratum of Tabela 3. Tolerates drastic pruning, attracts pollinators, and is prolifically productive.

Where it fits in a guild
Guava takes the High stratum in the Secondary I phase of succession — in a guild it shares the line with species from the other strata, each harvesting light at its own height, in its own time.
