A taxonomic treatment of Chrysocephalum apiculatum and C. semipapposum (Asteraceae: Gnaphalieae)
WILSON, PAUL G., Nuytsia 27: 33–73 (2016)
Chrysocephalum apiculatum (Labill.) Steetz and C. semipapposum (Labill.) Steetz are treated as distinct and endemic to Australia. In C. apiculatum 29 subspecies are recognised: subsp. apiculatum, subsp. orarium Paul G.Wilson, subsp. congestum Paul G.Wilson, subsp. gracile Paul G.Wilson, subsp. filifolium Paul G.Wilson, subsp. caespitosum Paul G.Wilson, subsp. ramosissimum (Hook.) Paul G.Wilson, subsp. insigne (Domin) Paul G.Wilson, subsp. simpliciusculum (Domin) Paul G.Wilson, subsp. semiamplexicaule (Domin) Paul G.Wilson, subsp. exile Paul G.Wilson, subsp. barbellatum Paul G.Wilson, subsp. odorum (DC.) Paul G.Wilson, subsp. arachnoideum (Domin) Paul G.Wilson, subsp. stoloniferum Paul G.Wilson, subsp. argenteum Paul G.Wilson, subsp. gracilescens (Domin) Paul G.Wilson, subsp. erectum Paul G.Wilson, subsp. pilbarense Paul G.Wilson, subsp. racemosum (J.Black) Paul G.Wilson, subsp. glandulosum Paul G.Wilson, subsp. variabile Paul G.Wilson, subsp. curvifolium (Domin) Paul G.Wilson, subsp. attenuatum Paul G.Wilson, subsp. flindersianum Paul G.Wilson, subsp. undulatum Paul G.Wilson, subsp. yorkense Paul G.Wilson, subsp. halmaturorum Paul G.Wilson, and subsp. norsemanense Paul G.Wilson. In C. semipapposum five subspecies are recognised: subsp. semipapposum, subsp. lineare Paul G.Wilson, subsp. brevifolium (Sond.) Paul G.Wilson, subsp. asperum (Steetz) Paul G.Wilson, and subsp. occidentale (Benth.) Paul G.Wilson.
Status of Senecio diaschides (Asteraceae) in Western Australia

Vigna triodiophila (Fabaceae: Phaseoleae), a new conservation-listed species from the Pilbara, Western Australia
HOLLAND, A.E. AND BUTCHER, R., Nuytsia 27: 77–83 (2016)
The new species described herein came to light during botanical surveys of the Burrup Peninsula and surrounds in 2000; it is geographically restricted to basalt rockpile habitats in the north-west of the Pilbara bioregion. Vigna triodiophila A.E.Holland & R.Butcher is diminutive in all its parts and can be readily distinguished from other Vigna Savi taxa in the Pilbara by its small (to 2.3(.3) cm long to 1.6(.2.1) cm wide), ovate to elliptic leaflets which lack lateral lobing. The species has a conservation listing of Priority Three in Western Australia.
Thismia tectipora (Thismiaceae) a new, unusual mitre-form species from tropical Australia
COWIE, I.D. AND LIDDLE, D.T., Nuytsia 27: 85–94 (2016)
A new tropical species, Thismia tectipora Cowie from Melville Island in the far north of the Northern Territory, Australia, is described and illustrated. The species is unique in the genus in having a thickened, fleshy, verrucose, cap-like mitre, the rim of which is reflexed to hide the pores in the upper perianth tube. It appears allied to taxa previously placed in Thismia Griff. sect. Sarcosiphon (Blume) Jonker, Geomitra Becc. and Scaphiophora Schltr. Available evidence suggests T. tectipora has a restricted distribution on Melville Island. Threats to the species, and its conservation status, are discussed.
Removal of six phrase names from the census of Western Australian vascular plants

Acacia citriodora (Fabaceae: Mimosoideae), a new species from northern Australia
KODELA, P.G. AND MASLIN, B.R., Nuytsia 27: 99–102 (2016)
An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 4. Malleostemon
RYE, B.L., Nuytsia 27: 103–120 (2016)
The following new species of Malleostemon J.W.Green are described: M. costatus Rye & Trudgen, M. microphyllus Rye & Trudgen, M. nephroideus Rye, M. nerrenensis Rye & Trudgen, M. pentagonus Rye & Trudgen, M. pustulatus Rye and M. uniflorus Rye. A new key is presented for the genus. Malleostemon sp. Kalbarri (L.A. Craven 7083) is reduced to synonymy under M. hursthousei (W.Fitzg.) J.W.Green and unnamed taxa that need further study are noted. Six of the new species have conservation priority.
