Eucalyptus merleae (Myrtaceae), a new rare species endemic to Ravensthorpe Shire in south-west Australia
MCQUOID, N.K. AND FRENCH, M.E., Nuytsia 32: 151–158 (2021)
Eucalyptus merleae McQuoid & M.E.French, first collected by Ian Brooker in 1985, is described and illustrated. It is related to Eucalyptus astringens Maiden. The new species has a scattered distribution in the Ravensthorpe to Hopetoun area on the central south coast of Western Australia, is at risk from frequent fire, climate change and potential mining activity, and is in need of further survey and monitoring.

Austrobaeckea, a new south-western Australian genus of Myrtaceae (Chamelaucieae: Hysterobaeckeinae)
RYE, B.L., Nuytsia 32: 173–197 (2021)
The new Myrtaceous genus Austrobaeckea Rye is described, with eight species recognised. It is a member of tribe Chamelaucieae DC. subtribe Hysterobaeckeinae Rye & Peter G.Wilson and is restricted to the southern part of the South West Botanical Province of Western Australia. Three new species are named as A. columnaris Rye, A. fascifolia Rye and A. narembeen Rye, and the following new combinations are made: A. latens (C.R.P.Andrews) Rye, A. pygmaea (R.Br. ex Benth.) Rye, A. pachyphylla (Benth.) Rye, A. uncinella (Benth.) Rye and A. verrucosa (Turcz.) Rye. A lectotype is selected for A. uncinella. Three species have conservation priority.
New species of Western Australian Styphelia (Ericaceae: Epacridoideae: Styphelieae) from the S. pendula and S. conostephioides groups
HISLOP, M., Nuytsia 32: 199–238 (2021)
Eight new species and one new subspecies are described and illustrated. Six of these, S. caudata Hislop, S. globosa Hislop, S. graniticola Hislop, S. intermediana Hislop, S. intricata Hislop and S. madida Hislop belong to the S. pendula (R.Br.) Spreng. group (also known as Group V), and the other two, S. carolineae Hislop and S. exarata Hislop, are from the S. conostephioides (DC.) F.Muell. group (also known as Group VIII). Styphelia madida includes the subspecies hirtigera Hislop. A key is provided to species of the S. pendula group occurring in the south-west corner of Western Australia (i.e. west of a line between Perth and Albany), this being the main region of diversity for the group. Five of the new species have conservation coding.
