DAVIS, R.W. AND HAMMER, T.A., Nuytsia 29: 157–160 (2018)
A taxonomic revision of species with a petaloid epicalyx bract allied to Lasiopetalum bracteatum (Malvaceae: Byttnerioideae)
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 29: 161–179 (2018)
This treatment focuses on an informal group of six species where Lasiopetalum bracteatum (Endl.) Benth., L. membranaceum (Steud.) Benth. and L. molle Benth. are revised and lectotypified, an updated description of the Threatened species L. rotundifolium Paust is provided, and two new related species of conservation concern, L. decoratum K.A.Sheph. & C.F.Wilkins and L. rupicola K.A.Sheph. & C.F.Wilkins, are described. Images and distribution maps are included.
Typification of Lasiopetalum and an interim key to the Western Australian species of the genus (Malvaceae: Byttnerioideae)
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia 29: 181–192 (2018)
Lasiopetalum ferrugineum Sm. is lectotypified and selected as the type for Lasiopetalum Sm. Notes on the variation within L. rosmarinifolium (Turcz.) Benth. are provided, with L. rosmarinifolium var. latifolium (Turcz.) Benth. and L. sp. Kukerin (C.A. Gardner 13646) treated as synonyms. A preliminary key to the species of Western Australian Lasiopetalum is also presented.
