New combinations of Hibbertia (Dilleniaceae) segregated from H. hibbertioides and H. glomerata
HAMMER, T.A. AND THIELE, K.R., Nuytsia 35: 31–45 (2024)
Infraspecific taxa within the southwest Australian species Hibbertia glomerata Benth. and H. hibbertioides (Steud.) J.R.Wheeler are critically re-evaluated. Morphological evidence is presented to recognise H. glomerata subsp. wandoo J.R.Wheeler and H. hibbertioides var. meridionalis J.R.Wheeler at species rank, as H. wandoo (J.R.Wheeler) T.Hammer & K.R.Thiele and H. meridionalis (J.R.Wheeler) T.Hammer & K.R.Thiele respectively. Hibbertia hibbertioides var. pedunculata J.R.Wheeler is reduced to synonymy under H. hibbertioides. The remaining subspecies in H. glomerata are provisionally retained but are marginally distinct.

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 nomenclatural update
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.

RYE, B.L., Nuytsia 35: 101–135 (2024)
A description is given for Thryptomene Endl. together with a key to all species and subspecies. Nine new Western Australian taxa are described as T. butleri Rye, T. caduca subsp. incurva Rye, T. conica Rye, T. dampieri subsp. capensis Rye, T. interzonensis Rye, T. jilbadji Rye, T. maritima Rye, T. maritima subsp. freycinetensis Rye and T. pieroniae Rye. Updated descriptions are given for T. caduca Rye & Trudgen, T. dampieri Rye and T. salina Rye & Trudgen and brief descriptions are given for three phrase-named taxa to inform future research. Thryptomene sp. Leinster (B.J. Lepschi & L.A. Craven 4362) is synonymised under T. decussata (W.Fitzg.) J.W.Green. Most of the new taxa are conservation-listed.

Stylidium miscellany IV: novel species, recircumscriptions and range extensions for northern Australia
WEGE, J.A., BRENNAN, K.G., BEAN, A.R., BARRETT, R.L., DILLON, S.J. AND BARRETT, M.D., Nuytsia 35: 141–198 (2024)
This paper advances knowledge of triggerplant diversity in monsoonal and arid Australia. The following 14 species are newly described: Stylidium aliforme Wege & Brennan (N.T.), S. anomalum Wege (W.A.), S. brachyotis Wege & Brennan (N.T.), S. brennanianum Wege, M.D.Barrett & A.R.Bean (W.A., N.T., Qld), S. contrarium Wege (N.T.), S. eludens Wege & A.R.Bean (Qld), S. incognitum Wege (W.A., N.T.), S. modicum M.D.Barrett, R.L.Barrett & Wege (W.A.), S. pezidium Wege, Brennan & S.J.Dillon (W.A., N.T., Qld), S. synaptum Wege, Brennan & A.R.Bean (W.A., N.T., Qld), S. tantillum Wege & Brennan (N.T.), S. torquatum Wege & Brennan (N.T.), S. tremendum Wege, M.D.Barrett & R.L.Barrett (W.A.) and S. youwanjela M.D.Barrett, R.L.Barrett & Wege (W.A.). Stylidium tenerrimum F.Muell. (W.A., N.T.) is recircumscribed and S. evolutum Carlquist (N.T.) reinstated to its original circumscription. Narrower circumscriptions of S. fissilobum F.Muell. (W.A., N.T.) and S. multiscapum O.Schwarz (W.A., N.T.) are presented and a lectotype designated for the latter. Stylidium tenerum Spreng. (N.T., Qld, P.N.G.) is placed into synonymy under S. uliginosum Sw. ex Willd. (south-east Asia), and S. symonii Carlquist (N.T.) synonymised under S. floodii F.Muell. (N.T., Qld). Stylidium elachophyllum A.R.Bean & M.T.Mathieson (Qld) and S. irriguum W.Fitzg. (W.A.) are recorded for the Northern Territory, while S. aquaticum A.R.Bean (N.T.) and S. capillare R.Br. (N.T., Qld) are recorded for Western Australia. A record of S. longibracteatum (W.A.) from Kata Tjuta in the Northern Territory is highlighted as having potentially unreliable locality information. Lectotypes are selected for S. claytonioides W.Fitzg., S. cordifolium W.Fitzg., S. irriguum W.Fitzg., S. rubriscapum W.Fitzg. and S. trichopodum F.Muell. Both S. pseudotenellum O.Schwartz and S. mitrasacmoides F.Muell. are treated as names of uncertain application. The existence of appropriated type fragments in Herbarium Lowrieanum, recently bequeathed to the Western Australian Herbarium, is noted.

WEGE, J.A. AND BRENNAN, K.G., Nuytsia 35: 199–216 (2024)
An annotated dichotomous key and photographic guide to Stylidium Sw. ex Willd. in the Northern Territory is provided. Stylidium gemmatum Wege & Brennan is formally described, and S. stenophyllum A.R.Bean placed into synonymy under a broadly circumscribed S. pachyrrhizum F.Muell.

Additions to the Styphelia pendula group (Ericaceae: Epacridoideae: Styphelieae) including updated descriptions for S. erubescens, S. pendula and S. retrorsa
HISLOP, M., Nuytsia 35: 233–262 (2024)
Six new species from the Styphelia pendula group, S. altivallis Hislop, S. innoxia Hislop, S. longiloba Hislop, S. porcata Hislop, S. speciosa Hislop and S. tarinensis Hislop are described and illustrated. Four of these are conservation-listed. Updated descriptions of three, long-established species from the group, S. erubescens F.Muell., S. pendula (R.Br.) Spreng. and S. retrorsa Hislop, Crayn & Puente-Lel. are provided for purposes of comparison. A key to those members of the S. pendula group with strictly pendulous inflorescences is also included.
