Generic Notes

Stirtonanthus Van Wyk & Schutte (1995a) was first published as Stirtonia Van Wyk & Schutte (1994), a later homonym of Stirtonia R. Brown (1900, a moss) and Stirtonia A.L. Smith (1926, a lichen). Drawings of the fruits and seeds were adapted from Van Wyk and Schutte (1994).

Tribal Notes

Tribe Podalyrieae

Van Wyk and Schutte (1995a) considered Liparieae and Podalyrieae to each be monophyletic and Sophoreae (2) to be their sister group. Schutte and Van Wyk (1998a, 1998b), using Crotalarieae (27) as outgroup, found that the genera of Liparieae and Podalyrieae coalesced into two closely related clades with Liparia (25.04) in the Podalyria (25.06) clade. This supported earlier suggestions (Polhill, 1976, 1981n, 1981o; Van Wyk and Schutte, 1995a) that Liparieae and Podalyrieae should be merged. Schutte and Van Wyk (1998a, 1998b) merged the two tribes as Podalyrieae, recognized the two clades as subtribes, Xiphothecinae and Podalyriinae, and erected a monotypic tribe for Hypocalytus (3.26.01), Hypocalypteae (26). The generic enumeration and number of species in each genus follows Schutte and Van Wyk (1998a). Van der Bank et al. (2002) carried out further cladistic analyses using DNA, morphological, and chemical data and confirmed the findings of Van Wyk and Schutte.
