BARRETT, M.D., CRAVEN, L.A. AND BARRETT, R.L., Nuytsia 19 (1): 1–8 (2009)

Calytrix gomphrenoides M.D.Barrett & Craven is described as a new species from sandstone pavements of the north-west Kimberley Region of Western Australia. It is apparently most closely related to C. inopinata Craven in the C. exstipulata DC. alliance. Emendations to a published key and notes on related species are provided.

Tetratheca plumosa (Elaeocarpaceae), a new species closely allied to Tetratheca similis from south-west Western Australia

Four new obligate seeder taxa of Eucalyptus series Rufispermae (Myrtaceae) from the transitional rainfall zone of south-western Australia

NICOLLE, D., Nuytsia 19 (1): 77–97 (2009)

Three new species are described, viz. E. vittata D.Nicolle, an obligate seeder previously confused with the respouter species E. sheathiana Maiden and also differing from the latter in the narrower adult leaves and smaller buds and fruits_; E. frenchiana _ D.Nicolle_,_ an obligate seeder from between Norseman and Hyden, previously confused with E. corrugata Luehm. but most closely related to E. pterocarpa C.A.Gardner ex P.J.Lang and differing from the latter in the smaller leaves, buds and fruits and the hemispherical opercula; and E. distuberosa D.Nicolle_,_ an obligate seeder previously confused with the respouter species E. pileata Blakely_._ Two subspecies are recognized in E. distuberosa, viz. subsp. distuberosa, of widespread but scattered distribution in the southern goldfields, and subsp. aerata D.Nicolle, restricted to Bronzite Ridge west of Norseman.

A new subspecies of Eucalyptus calycogona described, differing from the other three subspecies of E. calycogona by the waxy branchlets, buds and fruits, the generally broader, dull adult leaves which are bluish at least when new, the consistently elliptical to ovate seedling leaves, and the generally larger flower buds and fruits. The new ubspecies is distributed on the eastern edge of the central wheatbelt in Western Australia, to the north-west of the distribution of subsp. calycogona. A key to E. ser_. Heterostemones_ Benth., a map indicating the distribution of E. calycogona in Western Australia, and illustration of the holotype and habit of E. calycogona subsp. miracula D.Nicolle & M.E.French are included.

A conspectus of the genus Amaranthus (Amaranthaceae) in Australia

PALMER, J., Nuytsia 19 (1): 107–128 (2009)

A synopsis of the 26 Amaranthus species known to occur in Australia is presented. Amaranthus centralis J.Palmer & Mowatt and A. induratus C.A.Gardner ex J.Palmer & Mowatt are described as new; distribution maps and photographs of the type specimens are included for these new species. Amaranthus undulatus R.Br. is the earliest correct name for the taxon currently known as A. pallidiflorus F.Muell., and lectotypes are selected for A. clementii Domin, A. leptostachyus Benth., A. macrocarpus Benth. and A. mitchellii Benth. A key to all species in Australia is presented.

A reduced circumscription of Balaustion and description of the new genus Cheyniana (Myrtaceae: Chamelaucieae)

RYE, B.L., Nuytsia 19 (1): 129–148 (2009)

The myrtaceous genus Balaustion Hook. is reduced to its original monotypic circumscription. Balaustion s. str. is closely related to Tilophloia Trudgen & Rye ms., both genera having stamens in a single circular series, broad filaments, a very large placenta and seeds with a large concave hilum, but Balaustion is distinguished by its prostrate habit with adventitious roots, basifixed anthers and long tubular flowers adapted to pollination by birds. A second bird-pollinated species with elongated flowers, previously known as B. microphyllum C.A.Gardner, is transferred into the new genus Cheyniana Rye as C. microphylla (C.A.Gardner) Rye. Since the type material of this species is missing, it is lectotypified on the original illustration. Another large-flowered species, but with more spreading, apparently insect-pollinated flowers, is described as C. rhodella Rye & Trudgen. Cheyniana is related to also Oxymyrrhine Schauer, which it resembles in its very reduced anthers and narrow filaments, but differs in its large colourful petals and woody indehiscent fruit. Both of the small genera treated in this taxonomic revision belong to the tribe Chamelaucieae and are restricted to the south-west of Western Australia.

Reinstatement of the Western Australian genus Oxymyrrhine (Myrtaceae: Chamelaucieae) with three new species

RYE, B.L., Nuytsia 19 (1): 149–165 (2009)

The south-western Australian genus Oxymyrrhine Schauer is reinstated and the type species, previously known as Baeckea polyandra F. Muell., is restored to its earlier name of O. gracilis Schauer.A lectotype is selected for B. polyandra and three new species, Oxymyrrhine cordata Rye & Trudgen, O. coronata Rye & ; Trudgen and O. plicata Rye & Trudgen_,_ are described. These four species make up a group described here as Oxymyrrhine s. str. and are distinguished from other members of Oxymyrrhine s. lat. and from all other genera of tribe Chamelaucieae by the broad cavity in the summit of their fruit. Oxymyrrhine s. lat. includes a particularly difficult species complex, which will be revised at a later time.

Three new species of Tecticornia (Chenopodiaceae, subfamily Salicornioideae) identified through Salinity Action Plan surveys of the wheatbelt region, Western Australia

SHEPHERD, K.A. AND LYONS, M.N., Nuytsia 19 (1): 167–180 (2009)

A number of potentially new species have been discovered through ongoing Government surveys of the wheatbelt region of Western Australia. Three new samphires identified from collections made in saline areas during these surveys are described here: Tecticornia annelida K.A.Sheph. & M.Lyons, T. sparagosa K.A.Sheph. & M.Lyons and T. loriae K.A. Sheph. & M.Lyons. Distribution maps and illustrations of these new species are included.

Guichenotia anota and Guichenotia apetala (Lasiopetaleae: Byttneriaceae or Malvaceae s. lat.) a new and a revised species endemic to the Ravensthorpe Range, south-west Western Australia

WILKINS, C.F. AND WHITLOCK, B.A., Nuytsia 19 (1): 181–190 (2009)

Guichenotia anota C.F.Wilkins is described as new and Guichenotia apetala A.S.George is revised. Both are endemic to the Ravensthorpe Range in south-west Western Australia. Cladistic analyses of morphological characters, and chloroplast and nuclear DNA sequences (Wilkins & Whitlock in prep.) show these two species to be most closely related to each other, and more closely related to Lasiopetalum Sm. than to Guichenotia J. Gay. As both are priority species for conservation, in an area with developmental pressures from mining, they require urgent description and revision, and are included here in the latter genus until their generic placement is certain. Anatomical leaf data is presented.

A new species of Pultenaea (Mirbelieae: Fabaceae) from Kundip, Western Australia

WILKINS, C.F., ORTHIA, L.A. AND CRISP, M.D., Nuytsia 19 (1): 191–196 (2009)

A new species Pultenaea craigiana C.F.Wilkins, Orthia & Crisp is described. It has affinity to P. brachytropis Benth. This species is endemic to the south-west of Western Australia and is a priority species for conservation. Conservation notes and a distribution map are provided.

Recombination of subspecies in Trihaloragis (Haloragaceae)

MOODY, M.L., Nuytsia 19 (1): 197 (2009)

Moody and Les (2007) recognized the genus Trihaloragis consisting of the single species Trihaloragis hexandra (F.Muell.) M.L.Moody & D.H.Les. Recombination of the three subspecies of Haloragis hexandra was overlooked at the time. Here new combinations of the three subspecies are presented.

Clarification of recent combinations in the genus Dysphania (Chenopodiaceae)

SHEPHERD, K.A. AND WILSON, PAUL G., Nuytsia 19 (1): 198–199 (2009)

In a paper commenting on the generic status of the Chenopodiaceae, Wilson (1987) noted an affinity between the representatives of Chenopodium L. subg. Ambrosia A.J.Scott and the genus Dysphania R.Br., based on the presence of both septate and glandular hairs as well as similarities in leaf shape, leaf venation, inflorescence structure and seed orientation. Mosyakin and Clemants (2002) later came to a similar conclusion and reassigned the North American representatives (both endemic and naturalised) of Chenopodium subg. Ambrosia to Dysphania.
