Today, the State Herbarium of South Australia published two article in Vol. 33 of its journal Swainsona online.

(1) L. Haegi, Grammosolen (Solanaceae – Anthocercideae) revisited (6.3mb PDF)

Hon. Research Associate Laurie Haegi is an expert on the plant family Solanaceae and revises Grammosolen in this paper, a genus he erected in 1981. One new species is newly described and another species transferred from Cyphanthera to Grammosolen. The genus now consists of four species with non-overlapping distributions, from the Avon Wheatbelt through the Coolgardie, Great Victoria Desert and Mallee regions in southern Western Australia, to the Great Victoria Desert, western Gawler Ranges, Eyre Yorke Block and the Murraylands in South Australia.

(2) F. Tiver, Rytidosperma robertsoniae (Poaceae), a new species from southern Australia (1.3mb PDF)

State Herbarium Associate Fleur Tiver describes a new species of grass from southern Australia, Rytidosperma robertsoniae. It was first recognised as different from R. caespitosum by Enid Robertson, because of its different chromosome number of 2n=24. However, only now, there are enough specimens of the new taxon available to evaluate its morphology and segregate to as new. The typical form of R. caespitosum is also discussed and illustrated, and a lectotype is chosen for that species.
