The families of flowering plants
Alternatively Aphloiaceae Takht.; ~ Flacourtiaceae.
Habit and leaf form. Trees and shrubs. Leaves evergreen; alternate (sometimes turning blue on drying); simple. Lamina entire; pinnately veined. Leaves exstipulate. Lamina margins usually serrate.
Leaf anatomy. Stomata present; anisocytic.
Axial (stem, wood) anatomy. Secondary thickening developing from a conventional cambial ring.
Reproductive type, pollination. Fertile flowers hermaphrodite. Plants hermaphrodite.
Inflorescence, floral, fruit and seed morphology. Flowers aggregated in inflorescences; in racemes, or in fascicles. Inflorescences axillary; in few-flowered fascicles or racemes. Flowers regular.
Perianth sepaline (petals lacking); 4–5(–6). Calyx 4–5(–6); polysepalous; much imbricate.
Androecium 30–100 (many). Androecial members unbranched; maturing centrifugally; free of the perianth; free of one another. Androecium exclusively of fertile stamens. Stamens 30–100 (many); polystemonous; filantherous (the filaments filiform, persistent). Anthers small. Pollen grains aperturate; 3 aperturate; colpate (?).
Gynoecium seemingly 1 carpelled. Carpels reduced in number relative to the perianth. The pistil 1 celled. Gynoecium seemingly monomerous; seemingly of one carpel; superior. Carpel non-stylate to stylate (with a sessile); apically stigmatic (the stigma pelatate); 2–10 ovuled (? few). Placentation marginal. Ovules biseriate; more or less campylotropous.
Fruit fleshy. The fruiting carpel indehiscent; baccate. Seeds sparsely endospermic. Embryo well differentiated. Embryo curved (horseshoe-shaped).
Geography, cytology. Paleotropical. Tropical. Tropical East Africa, Madagascar, Mascarene Is.
Taxonomy. Subclass Dicotyledonae; Crassinucelli. Dahlgrens Superorder Violiflorae; Violales. Cronquists Subclass Dilleniidae; Violales. APG 3 core angiosperms; core eudicot; Superorder Rosanae; malvid; Order Crossosomatales.
Species 1 (polymorphic). Genera 1; only genus, Aphloia.
General remarks. A very incomplete description. APG (1998) employ the name Aphloiaceae.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, distributions of character states within any set of taxa, geographical distribution, genera included in each family, and classifications (Dahlgren; Dahlgren, Clifford, and Yeo; Cronquist; APG). See also Guidelines for using data taken from Web publications.
