Pultenaea and Ferns

Pultenaea Sm.

Pultenaea is a genus of flowering plants in the family Fabaceae that are native to Australia. They are commonly known as Bush-peas. Pultenaea contains 126 species, all of which only occur in Australia1. Between 1920 and 1928 Williamson published a five-part series entitled, ‘A Revision of the Genus Pultenaea’ in the Proceedings of the Royal Society of Victoria2.

During this period Williamson, alongside colleagues from the Field Naturalists’ Club of Victoria, also worked on the greatly anticipated publication of ‘A Census of the Plants of Victoria’ parts I3 and II4. Williamson was credited for his contributions to A.J. Ewart’s ‘Flora of Victoria’5, where he was acknowledged as ‘providing the account of the whole of the Leguminosae’ and for partial revision of the manuscript and proofs for the book.

Ferns of Victoria

Williamson is best remembered for his work with the genus Pultenaea; however, he contributed many more publications to scientific literature, with reports including ‘The Aquatic Plants of Victoria’9, The Clubmosses’10, ‘The Lilies of Victoria’11 and his report describing Victorian Alpine flora in ‘A Trip to the Bogong High Plains’12. Another example of his vast knowledge of Victorian flora can be seen in his work ‘Victorian Ferns’13. This detailed monograph of Victorian Ferns (right) was released by H.B. in 1926 and was originally published as a four-part report in the Victorian Naturalist.

Fern specimens collected by Williamson were gifted to the Field Naturalists’ Club of Victoria along with other national and international herbaria.

Subsequent treatments of Victorian and Tasmanian Ferns were published by the Field Naturalists’ Club of Victoria (193414, 195515, and 197516) that drew on Williamson’s descriptions and sets of his original line drawings from his 1926 articles were featured throughout all three publications.
The book entitled ‘Victorian Ferns’  authored by Charles Barrett and Richard Bond14 included this dedication:
