Notes

Also see Bonnetiaceae. Subfamilies Kielmeyeroideae - seeds without arils, cotyledons separate; and Hypericoideae - fruit capsule or berry, rarely drupe, seeds 5-many, without arils, cotyledons free; Calophylloideae - fruit drupe or occasionally capsule with 1–4 seeds without arils, embryo large with united cotelydons; Moronbeioideae - fruit berry with (1)-many seeds without arils and embryos undifferentiated; Clusioideae - subdivided into Clusieae - fruit usually capsule with 5-many seeds with arils, embryo with large hypocotyl and vestigal to no cotyledons; and Garcinieae - fruit drupe with 1–5(-13) seeds without arils, embryo with large hypocotyl and no cotelydons. Goldberg recognized Clusiaceae & Hypericaceae.

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.
