president's address. 11 



Miss Marjorie I. Collins, Linnean Maeleay Fellow of the Society in Botany, 

 lias eontributed two papers to the Proceedings during the year — "Note on Certain 

 Variations of the Sporoeyst in a species of Saproleii'uia," and "On tlie Structure 

 of the Resin- Secreting Glands in some Australian Plants,'' the observations for 

 both papere having been made while she was demonstrating in Butany in the 

 University of Adelaide. 



Miss Collins has continued her observations on the secretion of resin in the 

 bud of some Australian plants and the resultant phenomenon of "leaf-laequeriug," 

 common in xer<)|)hytic floras. At the same time she has also devoted some of her 

 time to an ecological study of the mangi-ove and saltmarsh vegetation at Cabbage 

 Tree Creek, Port Hacking. The encroaehment of certain i)lant a.ssociations upon 

 the partially drained salt-marsh has been observed, and samples of tlie soil collect- 

 ed from suitable plaees on the mangrove and salt-marsh area.s have been investi- 

 gated. In continuation of this side of her work, Miss Collins proposes to select 

 another area for detailed ecological study, preferably a region with low annual 

 rainfall . • 



Six applications for Linnean Mardeay Fellowships, 1021-22, were received in 

 response to the Council's invitation of 27th October, 1920. I have now the plea- 

 sure of making the firet public announcement of the Council's re-appointment for 

 another year from 1st April, 1921, of Dr. J. M. Petrie, Miss V. Irwin Smith 

 and Miss Marjorie 1. Collins to Fellowships in Biochemistry, Zoology, and Botany 

 respectively; and of the appointment for one year of Miss Marguerite Henry, 

 B.Sc, to a Fellowship in Zoology from 1st proximo. On behalf of the Society 

 I have much pleasure in wishing them a very successful year's research. 



Miss Henry has already had sufficient experience of research work to justify 

 our expectation that her proposed research on the Freshwater Entomostraca of 

 Australia and New Zealand, with special reference to their ecological distribution 

 will form a worthy addition to the growing volume of work accomplished by the 

 Linnean Maeleay Fellows. 



Miss Henry graduated in Science at the University of Sydney in 1917 with 

 second class Honours in both Zoology and Botany. The same year she was ap- 

 pointed assistant-zoologist to the Committee of the Commonwealth Advisory 

 Council of Science and Industry for the investigation of worm nodules in cattle, 

 and has since been continuously engaged on this work. This investigation into the 

 life-history of the parasitic Nematode (Onchncerca gihsoiii) has involved a wide 

 search for the intermediary host, in the coui-se of which especial attention has 

 been paid to tbe Tabanidae and freshwater Crustacea. As a result, apart from 

 the routine work involved, she has published three original papers, two of them, 

 "On some Australian Cladocera,'' and "On some Australian Freshwater Copepoda 

 and Ostracoda,'' in the .Tournal and Proceedings of the Royal Society of N.S.W., 

 and one (in collaboration with Dr. E. W. Ferguson), "Tabanidae from Camden 

 Haven District. N.S.W." in Part iv. of our Proceedings for 1010. 



Dr. Walkom's duties as Secretary have allowed liira some time to continue his 

 researches on Australian Fossil Plants, and during the year he has completed an 

 account of the .Jnrassic Plants from Talbragar, N.S.W., which has just appeared 

 as a memoir of the Geological Survey of N.S.W. He has alsQ almost com]ileted 

 the examination of the Glossopteris Flora of Queensland, in the course of which 

 he has discovered an extremely interesting association of seeds with leaves of 

 Glossopteris. The association appears to be sufficiently close to warrant the as- 

 sertion that the seeds are those of a species of Glossopteris, and should this be
