Revision of the multi-ovulate species of Thysanotus (Asparagaceae), with three new species
MACFARLANE, T.D. AND FRENCH, C.J., Nuytsia 35: 55–76 (2024)
The group of Thysanotus species having more than two ovules per ovary locule (the multi-ovulate species) is taxonomically revised. The three previously described species, T. brachyantherus Brittan, T. lavanduliflorus Brittan and T. nudicaulis Brittan, are maintained and redescribed, with T. nudicaulis being redefined following removal of two new species previously included in its concept. Three new species are described: T. argillaceus T.Macfarlane & C.J.French, T. ellipsoideus T.Macfarlane & C.J.French and T. prospectus C.J.French & T.Macfarlane. The South Australian records of T. nudicaulis are recognised as belonging to T. ellipsoideus. A key to the group and illustrations of some characters are provided and all species are mapped and illustrated photographically.
Typifications in Malleostemon, Micromyrtus, Scholtzia and Thryptomene (Myrtaceae) and a hybrid designation
WEGE, J.A. AND RYE, B.L., Nuytsia 35: 77–81 (2024)
As part of revisionary work in Myrtaceae tribe Chamelaucieae, lectotypes are selected for Malleostemon decipiens (W.Fitzg.) Trudgen, M. tuberculatus (E.Pritz.) J.W.Green, Micromyrtus imbricata Benth., M. sulphurea W.V.Fitzg., Scholtzia ciliata F.Muell., S. teretifolia Benth., S. uberiflora F.Muell. and Thryptomene kochii E.Pritz., and the type of Micromyrtus erichsenii Hemsl. is clarified. Micromyrtus chrysodema Rye is hypothesised to be a hybrid between M. flaviflora (F.Muell.) J.M.Black and a 2-ovulate, white-flowered species of Micromyrtus Benth.
