Description of six Lepidosperma species (Cyperaceae) based on type specimens
BARRETT, R.L., Nuytsia 22 (5) :
Many species of Lepidosperma Labill. have been poorly circumscribed, resulting in significant nomenclatural confusion. Full descriptions of six species based solely on type specimens held in the Webb Herbarium in Florence (FI-W) and the Preiss Herbarium in Lund (LD) are presented here in order to facilitate accurate application of the names involved. Descriptions are provided for Lepidosperma costale Nees, L. gladiatum Labill., L. fimbriatum Nees, L. humile (Nees) Boeck., L. longitudinale Labill. and L. squamatum Labill., as well as notes about these species.
A new species of Monotoca (Ericaceae: Styphelioideae: Styphelieae) from the south coast of Western Australia
CHAPMAN, A.R., Nuytsia 22 (5) :
A new species, Monotoca aristata A.R. Chapman from the west of Fitzgerald River National Park is described and illustrated. It is distinguished from all other Monotoca species by the thick, aristate, linear-lanceolate leaves, with conspicuous veins on the abaxial surface. It is now the only representative of this genus in Western Australia.
Solanum albostellatum (Solanaceae), a new species from the Pilbara bioregion of Western Australia
DAVIS, R.W. AND HURTER, P.J.H., Nuytsia 22 (5) :
Solanum albostellatum R.W.Davis & P.J.H.Hurter has recently been discovered and is formally described. The new species is morphologically similar to S. oldfieldii F.Muell. and S. esuriale Lindl. Solanum albostellatum inhabits cracking clay environments extending from Millstream Chichester National Park to the Hamersley Range, west of Newman. An amendment to the Flora of Australia key for Solanum to account for S. albostellatum is included, as is a table summarising the similarities and differences between S. albostellatum and the most similar taxa.
Ptilotus christineae is synonymous with the previously Presumed Extinct taxon P. pyramidatus
DAVIS, R.W., Nuytsia 22 (5) :
While curating the Ptilotus R.Br. collection at the Western Australian Herbarium, I came across a small line drawing of the Presumed Extinct species P. pyramidatus (Moq.) F.Muell. This name is based on a Drummond collection of unknown provenance. It was immediately clear from the habit depicted that it could represent an earlier name for the recently published P. christineae R.W.Davis & Tauss. Subsequent examination of type material confirmed that P. pyramidatus is conspecific with P. christineae and the latter name must therefore be reduced to synonymy. The specimens collected in Perth in late 2010, which formed the basis for the description of P. christineae, represent the first collections of P. pyramidatus for more than 160 years.
A newly discovered population at Cape Le Grand supports Lucky Bay as the type locality of Banksia plumosa (Proteaceae)
MARKEY, A., Nuytsia 22 (5) :
The type gathering of Banksia plumosa (R.Br.) A.R.Mast & K.R.Thiele was collected by Robert Brown from Bay 1 (Lucky Bay, c. 35 km east of Esperance) in January 1802 (Figure 1). Over the following two centuries, further collections of this species have been made in an area from the Stirling Range and Albany eastwards to the Fitzgerald River (Western Australian Herbarium 1998–). However, B. plumosa has not been recorded again from any area east of Bremer Bay. George (1999) concluded that the type locality was in error, and that the more likely type location was in the Albany district (King George Sound), where Brown collected from late December 1801 to early January 1802 (Vallance et al. 1993).
