Notes on Eucalyptus series Orbifoliae (Myrtaceae) including a new species from central Australia
NICOLLE, D., Nuytsia 13 (3): 487–493 (2001)
A key and distribution map for all taxa of Eucalyptus ser. Orbifoliae Brooker & Hopper are provided. Eucalyptus minniritchi Nicolle is described to accommodate populations of mallees in central Australia previously referred to as E. orbifolia F. Muell. or E. websteriana Maiden and related to both. The new species differs from E. orbifolia in the smaller buds with a short hemispherical operculum, the smaller and narrower adult leaves and the generally smaller, hemispherical fruits and differs from E. websteriana in the consistently and strongly pruinose adult parts and generally coarser leaves, peduncles, pedicels, buds and fruits. E. lata L.A.S. Johnson & K.D. Hill, a species recently described to accommodate what is here recognized to be typical E. orbifolia, is synonymised with that earlier named species. The status of E. educta L.A.S. Johnson & K.D. Hill and its relationship to E. orbifolia is discussed.
A taxonomic update of Stenanthemum (Rhamnaceae: Pomaderreae) in Western Australia
RYE, B.L., Nuytsia 13 (3): 495–507 (2001)
A generic description of Stenanthemum Reissek is given, together with a key and distribution maps for the 23 species occurring in Western Australia. Stenanthemum leucophractum (Schledl.) Reissek is nominated as the type species of the genus. Three new species from south-western Australia, Stenanthemum liberum Rye, S. patens Rye and S. sublineare Rye, are described and illustrated, and new seed measurements are given for S. cristatum Rye. All of the new species have conservation priority.
A taxonomic revision of Thryptomene section Thryptomene (Myrtaceae)

The differences between this species and A. juniperina Schauer are discussed.
A taxonomic revision of the Western Australian genus Lysiosepalum (Malvaceae: Lasiopetaleae)
WILKINS, C.F. AND CHAPPILL, J.A., Nuytsia 13 (3): 571–594 (2001)
A taxonomic revision of Lysiosepalum F. Muell., a genus endemic to south-western Australia, identified five species. These comprise two currently accepted species L. involucratum (Turcz.) Druce and L. rugosum Benth., the reinstated L. hexandrum (S. Moore) S. Moore and two new species L. abollatum C.F. Wilkins (CALM Priority One) and L. aromaticum C.F. Wilkins (CALM Priority Two) that probably require recognition as Declared Rare Flora. A cladogram based on morphological data indicates that Lysiosepalum is a monophyletic genus, strongly supported by three synapomorphies unique in tribe Lasiopetaleae: calyx tube very short (lobes scarcely fused at the base); calyx lobes of alternating broad and narrow widths; epicalyx bracts equally spaced to completely enclose the mature bud. A chromosome number of n = 10 for L. involucratum is the first published record for the genus.
Leiocarpa, a new Australian genus of the Asteraceae tribe Gnaphalieae
WILSON, PAUL G., Nuytsia 13 (3): 595–605 (2001)
A new genus Leiocarpa Paul G. Wilson (Gnaphalieae: Asteraceae) is described; it is circumscribed to include the species that have been placed in Ixiolaena Benth., other than the type, two of the species placed in Leptorhynchos Less., and two species currently in Chrysocephalum Walp. The characters that distinguish Ixiolaena, Leiocarpa, Leptorhynchos, and Chrysocephalum are discussed. The ten species recognized in the new genus are as follows: L. brevicompta (F. Muell.) Paul G. Wilson, L. gatesii (H.B. Will.) Paul G. Wilson, L. leptolepis (DC.) Paul G. Wilson, L. panaetioides (DC.) Paul G. Wilson, L. pluriseta (Haegi) Paul G. Wilson, L. semicalva (F. Muell.) Paul G. Wilson, L. serpens (Everett) Paul G. Wilson, L. supina (F. Muell.) Paul G. Wilson, and L. tomentosa (Sond.) Paul G. Wilson. One new subspecies is described: L. semicalva subsp. tenuifolia Paul G. Wilson, and one new subspecific combination, Leiocarpa semicalva subsp. vinacea (Haegi) Paul G. Wilson, is made. Lectotypes are chosen for L. brevicompta, L. tomentosa, L. semicalva, and L. supina.

Two new species of Leptorhynchos Less. are described, L. orientalis Paul G. Wilson which is found in South Australia, New South Wales, and Victoria, and L. melanocarpus Paul G. Wilson which is restricted to gypseous mounds on a salt lake in South Australia. The typification of the generic name is discussed and a lectotype is chosen for L. tenuifolius F. Muell.
New species and notes on central Australian Goodenia (Goodeniaceae)
ALBRECHT, D.E., Nuytsia 15 (1): 1–9 (2002)
Goodenia halophila Albr. sp. nov. and G. cylindrocarpa Albr. sp. nov. are described, with notes on their distribution, conservation status, habitat and relationships with other species of Goodenia Sm. Notes are also provided on the Northern Territory populations of G. angustifolia Carolin and G. glandulosa K.Krause, and on all populations of G. anfracta J.M.Black and G. maideniana W.Fitzg. Further studies are needed to establish whether G. anfracta, which currently has conservation priority in Western Australia, should be reduced to synonymy under G. maideniana.
A revision of Byblis (Byblidaceae) in south-western Australia
CONRAN, J.G., Nuytsia 15 (1): 11–19 (2002)
The south-western Australian populations of Byblis (Byblidaceae) are revised. A new species, B. lamellata Conran & Lowrie, is recognised on habit, ecology and seed morphology and named for the populations between Arrowsmith River and Cataby. Byblis gigantea Lindl. and its synonym B. lindleyana Planch. are lectotypified. A generic description and a table of distinguishing features for all species is given. A key and distribution map are provided for the two species from the south-west of Western Australia.

A comparison of the leaf anatomy of Ficus subpuberula, F. atricha, and F. brachypoda (Moraceae: Urostigma sect. Malvanthera)
DIXON, D.J., Nuytsia 15 (1): 27–32 (2002)
The leaf anatomy of Ficus subpuberula Corner, F. atricha D.J.Dixon, and F. brachypoda (Miq.) Miq. are compared in order to facilitate identification of these partly sympatric species. Ficus subpuberula was found to possess distinctly thinner (267.6 ± 4.3 µm), isobilateral leaves compared to the much thicker (313.3 ± 12.1 µm and 425.6 ± 17.8 µm), dorsiventral leaves of F. atricha and F. brachypoda respectively. Tanniniferous cells were present in F. atricha and F. brachypoda, but absent in F. subpuberula. The upper epidermis and the palisade parenchyma of F. brachypoda were about twice as thick as in F. atricha.
