Notes

Endocarp with distal operculum, often large (monkey-pots) or drupe or berry. Goldberg: recognized Lecythidaceae (fruit woody capsule, apically dehiscent, or berry); Barringtoniaceae (fruit fibrous berry, drupe, or dry 4-winged and indehiscent); and Asteranthaceae (fruit large berry or loculicidal capsule with persistent calyx (Asteranthos). Mabberley: Subfamilies: 1. Lecythidoideae (fruit berry or capsule of tropical America); 2. Napoleonaeoideae (Asteranthaceae and capsule with large calyx, or large berry of New World); 3. Foetidioideae (fruit drupe of Old World); 4. Planchonioideae (fruit usually 1-seeded berry or dry 4-winged dehiscent capsule of Old World).

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, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
