Come and hear how an excavator can be used for positive outcomes in large- scale aquatic plant restoration.

The aquatic plant, Ruppia tuberosa is a key primary producer in the Coorong, providing food (foliage, turions, seeds) for waterbirds, and habitat for fish and invertebrates. During the millennium drought, the population of R. tuberosa in the Coorong was severely depleted, including its seed bank. Therefore when improved water conditions returned, the plant was not able to respond quickly without intervention. Continue reading →

State Herbarium botanist honoured

Kunzea toelkenii

A new species of New Zealand kānuka genus Kunzea was named after State Herbarium Hon. Associate Dr Hellmut Toelken.  Peter de Lange, botanist at the New Zealand Department of Conservation, published the results of a 15-year study examining Kunzea ericoides, a taxon that was thought to be shared between New Zealand and Australia.  De Lange examined the plants with traditional herbarium studies, hybridisation, molecular and ecological studies.  It turned out that K. ericoides does not occur in Australia, and that there are actually ten different species in New Zealand, seven of which were newly described in his revision, among them Kunzea toelkenii de Lange.  Hellmut Toelken is joint author of four of the new species and combinations in the paper, and was acknowledged by Peter de Lange for his long-standing research interest in Kunzea and his contributions to the taxonomy of the genus.

New Journal article, Dec. 2014

Goodenia valdentata

Yesterday, 24 Dec. 2014, the Journal of the Adelaide Botanic Gardens published the last paper for year. Peter Lang from the State Herbarium of South Australia describes a new species of Goodenia, restricted to a small area in the arid centre of the State.

Goodenia valdentata (Goodeniaceae), a new rare species endemic to Davenport Range, South Australia (2.5mb PDF)

Nine collections are known of this species, the first from 1968, but they were for a long time mistaken for Goodenia saccata or G. chambersii. The new species belongs to Goodenia subsect. Goodenia and is related to G. grandiflora and similar taxa. This increases the number of species of the genus in South Australia to 46.
