Revision of Leptosema (Fabaceae: Mirbelieae)

Abstract

Leptosema has 13 species with pea-flowers modified for bird-pollination. It is endemic to Australia, being distributed widely in the west, centre, north and north-east of the continent. This paper is a monograph of the genus. Updated cladistic and biogeographic analyses are presented and, based on the former, a new classification is formalised. Taxa described as new are Leptosema sect. Leptosema, L. ser. Callipetalum, L. cervicorne Crisp, L. chapmanii Crisp, L. villosum Crisp, L. sect. Oolobium Crisp and L. ser. Pereostemon Crisp. New combinations or ranks are made for L. aphyllum (Hook.) Crisp, L. macrocarpum (Benth.) Crisp, L. tomentosum (Benth.) Crisp, L. uniflorum (R.Br. ex Benth.) Crisp, and L. sect. Burgesia (F.Muell.) Crisp. Lectotypes are chosen for the synonyms Brachysema aphyllum Hook., B. chambersii (F.Muell.) F.Muell. ex Benth., B. macrocarpum Benth., B. oxylobioides (F.Muell.) Benth., B. uniflorum R.Br. ex Benth., Burgesia homaloclada F.Muell., Jacksonia anomala Ewart and Morrison, J. petrophiloides W.Fitzg. and Templetonia regina J.L.Drumm. Show more
