are described as new species. Haemodorum basalticum and H. macfarlanei are restricted to the Mitchell Plateau, H. capitatum is restricted to pindan sands in the Dampier Botanical District, H. condensatum is known from a small area in the remote Prince Regent National Park, H. griseofuscum is only known from a single location on Doongan Station in Western Australia, although possibly also occurs in the Northern Territory, H. interrex is restricted to the area around the headwaters of the Prince Regent River, and H. thedae is only known from Theda Station. A key is presented to all species known to occur in the Kimberley region, and H. subvirens F.Muell. and H. coccineum R.Br. are newly recorded for the region.

Wurmbea calcicola (Colchicaceae), a new species from Cape Naturaliste, south western Australia

Macfarlane, T.D. A new species of Neurachne (Poaceae) from Western Australia. Nuytsia 17: 215-222 (2007). Neurachne annularis T.Macfarlane is described and illustrated with photographs and a distribution map. The new species forms Triodia-like hummocks and grows on and around banded ironstone ranges in the Yilgarn region of Western Australia where it is often dominant in the understorey. The species has the C 3 photosynthetic pathway and is diploid with n = 9, one of three species with that combination in a genus now of seven species. It is morphologically closest to N. tenuifolia S.T.Blake, from ranges in Central Australia.

Recent work on Bossiaea Vent. (Fabaceae) of Western Australia includes a full conspectus by Ross (2006), two further new species by Barrett and Barrett (2015) and a review by Keighery (2018) of the B. eriocarpa Benth. and B. ornata (Lindl.) Benth. group, including the resurrection of two species from synonymy and the description of a new species. Currently there are 42 described species in Western Australia and two phrase-named taxa (Western Australian Herbarium 1998-), of which B. sp. Frankland (E.M. Sandiford EMS 896) was described and illustrated by Ross (2006) but not formally named given the paucity of available material. Further study of this taxon in the field and herbarium has convinced us that it is a distinct species that merits formal description.

Macfarlane, T.D. & Case, A.L. Wurmbea fluviatilis (Colchicaceae), a new riverine species from the Gascoyne region of Western Australia. Nuytsia 21(1): 25-30 (2011). A new species of Wurmbea, W. fluviatilis T.Macfarlane & A.Case, is described and illustrated with photographs and a distribution map. The new species is known from only three populations from the Gascoyne River catchment in the region of Mount Augustus, growing on river banks and beside riverside pools. It is a relatively tall, attractive species with bi-coloured flowers.
