A taxonomic review of the Solanum sturtianum subgroup of subgenus Leptostemonum (Solanaceae)
BEAN, A.R., Nuytsia 23: 129–161 (2013)
The informal taxonomic subgroup typified by Solanum sturtianum F.Muell. comprises those species that have stellate hairs, black mature fruits with a thin brittle pericarp, and brown to black seeds. The subgroup is endemic to Australia. Ten species are recognised here: S. sturtianum is maintained, S. morrisonii Domin is reinstated, and eight new species are described viz. S. austropiceum A.R.Bean, S. elatius A.R.Bean, S. iodinum A.R.Bean, S. kentrocaule A.R.Bean, S. octonum A.R.Bean, S. piceum A.R.Bean, S. pycnotrichum A.R.Bean and S. reclusum A.R.Bean. A lectotype is chosen for S. morrisonii. Descriptions, illustrations and distribution maps are provided for all species.
A re-assessment of the varieties recognised in Verticordia plumosa (Myrtaceae: Chamelaucieae)
HARRIS, A.M. AND RYE, B.L., Nuytsia 23: 163–170 (2013)
The seven varieties of Verticordia plumosa (Desf.) Druce are re-assessed in the light of recent collections. Verticordia plumosa var. pleiobotrya A.S.George is reduced to a synonym of V. plumosa var. brachyphylla (Diels) A.S.George. A key and distribution maps are provided for the six remaining varieties, two of which have conservation priority.
