A new species of Sphaerolobium Sm. that has been collected from three widely spaced locations in the extreme south-west of Western Australia is described and illustrated. Sphaerolobium benetectum R. Butcher is one of a group of species possessing a distinctly black-spotted calyx and is most closely related to S. drummondii Turcz. and S. validum R. Butcher ms.

Ficus lilliputiana (Moraceae), a new species from the Kimberley region of Western Australia and the Northern Territory

DIXON, D.J., Nuytsia 13 (3): 457–464 (2001)

Ficus lilliputiana D.J. Dixon, a new species in subgenus Urostigma sect. Malvanthera Corner is described from the East Gardiner District of Western Australia and the Victoria River District of the Northern Territory. This lithophytic species is restricted to the sandstone escarpments around Kununurra and the Keep River National Park. Ficus lilliputiana is distinct, being the smallest taxon in the section and the only one to have a prostrate habit. Two forms are recognized, F. lilliputiana f. lilliputiana and F. lilliputiana f. pilosa D.J. Dixon, and are differentiated on the basis of the presence or absence of an indumentum. A key to the forms and notes on distribution, ecology, reproduction, conservation status and etymology are provided.

KEIGHERY, G.J., Nuytsia 13 (3): 471–474 (2001)

Isotropis cuneifolia subspecies glabra Keighery is described and illustrated. The subspecies is considered endangered, being confined to a small area around Gingin on the Swan Coastal Plain, Western Australia.

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)

RYE, B.L. AND TRUDGEN, MALCOLM E., Nuytsia 13 (3): 509–528 (2001)

Five new species and a new subspecies are described. These are Thryptomene australis subsp. brachyandra Rye & Trudgen, T. costata Rye & Trudgen, T. eremaea Rye & Trudgen, T. duplicata Rye & Trudgen, T. salina Rye & Trudgen and T. striata Rye & Trudgen. Thryptomene johnsonii F. Muell. is reinstated, T. prolifera Turcz. is reduced to a synonym of T. mucronulata Turcz., and a lectotype is selected for T. dielsiana E. Pritz., which is another synonym of T. mucronulata.

New taxa in Goodenia (Goodeniaceae) from the Kimberley region of Western Australia

SAGE, L.W., Nuytsia 13 (3): 529–536 (2001)

Three new Goodenia species, G. crenata Carolin & Sage, G. inundata Sage & Pigott and G. psammophila Sage & M.D. Barrett, are described and illustrated. The subspecies of G. psammophila subsp. hiddinsiana Sage & M.D. Barrett is also described. G. crenata, G. inundata and both G. psammophila subspecies are recommended for listing as priority flora for conservation.

Reinstatement and revision of Euryomyrtus (Myrtaceae)

TRUDGEN, MALCOLM E., Nuytsia 13 (3): 543–566 (2001)

Euryomyrtus Schauer is reinstated and lectotypified. A revision of the genus with descriptions, maps, illustrations and a key is presented. Seven species are recognized for the genus which is endemic to southern Australia, including Tasmania. Euryomyrtus denticulata (Maiden & Betche) Trudgen, E. leptospermoides (C.A. Gardner) Trudgen, E. maidenii (Ewart & Jean White) Trudgen, E. ramosissima (A. Cunn.) Trudgen and E. ramosissima subsp. prostrata (Hook. f.) Trudgen are new combinations, and E. inflata Trudgen, E. patrickiae Trudgen and E. recurva Trudgen are new species. The closest relatives of the genus are considered to be in a natural group which includes Rinzia Schauer, Hypocalymma Endl., Ochrosperma Trudgen and Triplarina Raf.

Agonis fragrans (Myrtaceae), a new species from Western Australia

WHEELER, J.R., MARCHANT, N.G. AND ROBINSON, C.J., Nuytsia 13 (3): 567–570 (2001)

Agonis fragrans J.R. Wheeler & N.G. Marchant is described and illustrated. This species, previously recognized by the cut-flower industry by informal names, now requires scientific recognition to further its development for an essential oil. 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.

Leptorhynchos (Asteraceae: Gnaphalieae), notes, new taxa and a lectotypification

WILSON, PAUL G., Nuytsia 13 (3): 607–611 (2001)

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.
