description
Casimiroa edulis grows as a semi-evergreen tree with a broad crown up to 18 meters high. The brownish, fine-furrowed bark has many lenticels .
The long-stemmed and alternate leaves are composed palmate with 3–7 leaflets . The fine-haired petiole is 5–12 centimeters long. The mostly short-stalked, almost bare, papery leaflets are 5-16 inches long and 2-7 inches wide. They are egg-shaped, -lanceolate to elliptical, lanceolate or obovate, -eilanceolate. The fine-haired leaflet stalks are up to 1.5 centimeters long. The sometimes wavy edge of the leaf is completely to mostly weakly serrated, notched and the tip of the leaf is usually pointed to pointed. The stipules are missing.
Terminal or axillary, slightly fine-bristled and shorter panicles are formed. The fragrant, small and five-fold, stalked flowers with a double flower envelope are greenish to whitish and usually hermaphrodite or sometimes functionally unisexual. The very small calyx is finely bristled with 5 tips. The 5 lobed petals are up to 7 millimeters long, elliptical and expansive. There are 5 stamens with thick, awlish stamens. The spherical, shortly lobed and fünfkammerige ovary is upper constant sedentary, star-shaped and lobed stigma . Male flowers contain a pestle and female flowers have staminodes with antherodes.
The rounded and greenish to yellow, thin-skinned, slightly leathery and mostly multi-seeded, bare stone fruits are 7-10 centimeters in size. They contain up to 5, about 25 millimeters long, whitish seeds that are located in a membranous membrane (pyrene).
The number of chromosomes is 2n = 36.
