Stylidium miscellany II: typification of some Sonder names and the description of a new subspecies of S. uniflorum
WEGE, J.A., Nuytsia 25: 197–208 (2015)
A full synonymy is presented for S. affine Sond. to include S. affine var. minus E.Pritz., a name previously treated as a synonym of S. caricifolium Lindl. Lectotypes are selected for four species described by Otto Sonder, namely S. lineatum Sond., S. pubigerum Sond., S. rupestre Sond. and S. uniflorum Sond. Stylidium rupestre f. abbreviatum Mildbr., S. rupestre f. congestum Mildbr., S. rupestre f. uniflorum Mildbr. and S. glaucum var. brownei DC. are formally placed into synonymy under S. rupestre, with lectotypes designated for S. rupestre f. abbreviatum and S. glaucum var. brownei. Revised descriptions are provided for S. rupestre and S. uniflorum, and S. uniflorum subsp. extensum Wege is newly described. Putative hybrids between both subspecies of S. uniflorum and S. leptophyllum DC. are recorded.
Recognition of Hysterobaeckea as a genus of Myrtaceae tribe Chamelaucieae
RYE, B.L., Nuytsia 25: 209–218 (2015)
Baeckea behrii Schltdl. is selected as the lectotype for B. subg. Hysterobaeckea Nied., which is raised to the generic level as Hysterobaeckea (Nied.) Rye. New combinations are made for the three named species that belong to the genus as now defined, and a lectotype is selected for one of those species, B. ochropetala F.Muell. The three new combinations are H. behrii (Schltdl.) Rye, H. ochropetala (F.Muell.) Rye and H. tuberculata (Trudgen) Rye. The distinguishing characters of the genus are outlined and a generic key given for the group to which it belongs.
A revision of the south-western Australian genus Babingtonia (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 25: 219–250 (2015)
In this revision of Babingtonia Lindl., 11 species are recognised, all endemic to the south-west of Western Australia. Previously, the type species B. camphorosmae (Endl.) Lindl. was the only Western Australian species housed as a Babingtonia. The new combination B. grandiflora (Benth.) Rye is made, and nine new taxa are named: B. cherticola Rye & Trudgen, B. delicata Rye & Trudgen, B. erecta Rye & Trudgen, B. fascifolia Rye, B. maleyae Rye & Trudgen, B. minutifolia Rye & Trudgen, B. pelloeae Rye & Trudgen, B. triandra Rye & Hislop and B. urbana Rye. A key is given and some of the taxa are illustrated. Most have conservation priority.

WILSON, PETER G. AND ROWE, R., Nuytsia 25: 251–284 (2015)
Twelve new species of Indigofera L. are described from the Eremaean Botanical Province: I. chamaeclada Peter G.Wilson & Rowe, I. cuspidata Peter G.Wilson & Rowe, I. decipiens Peter G.Wilson & Rowe, I. eriophylla Peter G.Wilson & Rowe, I. fractiflexa Peter G.Wilson & Rowe, I. gilesii Peter G.Wilson & Rowe, I. kingiana Peter G.Wilson & Rowe, I. melanosticta Peter G.Wilson & Rowe, I. occidentalis Peter G.Wilson & Rowe, I. oraria Peter G.Wilson & Rowe, I. roseola Peter G.Wilson & Rowe and I. warburtonensis Peter G.Wilson & Rowe. A lectotype is designated for the name I. boviperda Morrison and three new subspecies, I. boviperda subsp. eremaea Peter G.Wilson & Rowe, I. fractiflexa subsp. augustensis Peter G.Wilson & Rowe and I. chamaeclada subsp. pubens Peter G.Wilson & Rowe, are recognised.
