New species of Leucopogon s. str. (Ericaceae: Epacridoideae: Styphelieae) from the Geraldton Sandplains
HISLOP, M., Nuytsia 27: 217–242 (2016)
Six new species of Leucopogon R.Br. (L. foliosus Hislop, L. grammatus Hislop, L. inflexus Hislop, L. prolatus Hislop, L. simulans Hislop and L. stenophyllus Hislop) are described, illustrated and their distributions mapped. Aspects of the morphology and taxonomy of the informal Northern Group of species are discussed and a comparison is made, in tabular form, between this group and two other informal groups, the L. pulchellus Sond. and L. carinatus R.Br. groups. A key to the species of Leucopogon s. str. from the Geraldton Sandplains bioregion is provided.
Status of the fern Histiopteris incisa (Dennstaedtiaceae) in southern Western Australia
KEIGHERY, G.J., Nuytsia 27: 243–244 (2016)
A new and rare species of Nymphoides (Menyanthaceae) from the North West of Western Australia
DAVIS, R.W., HAMMER, T.A. AND THIELE, K.R., Nuytsia 27: 245–252 (2016)
Nymphoides walshiae R.W.Davis & K.R.Thiele, a new and rare species of Nymphoides Ség., is described. This new species is geographically disjunct from other Nymphoides species, occurring in a small area of arid Western Australia near the Cape Range. A molecular phylogenetic analysis based on ITS sequences suggests that it occupies a phylogenetically isolated position sister to the largest clade in the genus. It lacks some of the more common features seen in the genus Nymphoides. A scanning electron microscope image displaying the seed surface and outline is provided.
New species of Eremophila (Scrophulariaceae): thirteen geographically restricted species from Western Australia
BUIRCHELL, B.J. AND BROWN, A.P., Nuytsia 27: 253–283 (2016)
Thirteen geographically restricted species of Eremophila R.Br. (E. ballythunnensis Buirchell & A.P.Br., E. capricornica Buirchell & A.P.Br., E. daddii Buirchell & A.P.Br., E. ferricola Buirchell & A.P.Br., E. hamulata Buirchell & A.P.Br., E. jamesiorum Buirchell & A.P.Br., E. laccata Buirchell & A.P.Br., E. pusilliflora Buirchell & A.P.Br., E. regia Buirchell & A.P.Br., E. resiliens Buirchell & A.P.Br., E. scrobiculata Buirchell & A.P.Br., E. victoriae Buirchell & A.P.Br. and E. yinnetharrensis Buirchell & A.P.Br.) are described and illustrated and their relationships with related species and conservation status are discussed.
Stenanthera pungens (Ericaceae: Epacridoideae: Styphelieae), a new combination, and a new genus for Western Australia
HISLOP, M., Nuytsia 27: 285–286 (2016)
Three new species from the Kimberley region of Western Australia from the families Caryophyllaceae, Convolvulaceae and Poaceae
BARRETT, R.L., Nuytsia 27: 287–298 (2016)
Polycarpaea umbrosa R.L.Barrett (Caryophyllaceae), Ipomoea johnsoniana R.L.Barrett (Convolvulaceae) and Eriachne pindanica R.L.Barrett (Poaceae) are described as new species endemic to the Kimberley region of Western Australia. A revised description of Eriachne semiciliata Lazarides is presented. Polycarpaea umbrosa and Ipomoea johnsoniana both have conservation-listing as Priority One taxa. All new species are illustrated.
