232 THE JOUR>"AL OF BOTA>'Y 



At the same meeting Mr. S. L. Moore followed with "A Contri- 

 hution to the Flora of Australia," which contains notices of rare and 

 descriptions of new Australian plants preserved in the British Museum. 

 Robert Brown's Trihulus Systrix and T. occidentalis are shown to have 

 been misunderstood by Bentham and succeeding writers, Bentham's 

 T. Jft/atrLv heing really T. oc cide?i talis, v,'heresis T. Hystrix. unknown 

 except in the type specimen, has much larger fruit with long subulate 

 appendages quite unlike the short conical ones of occideiitalis. Two 

 recent West Australian collections, one by Dr. Stoward, the other by 

 Mr. Marvon, have yielded many novelties, the most interesting being 

 a second species of the Goodeniaceous genus Symjyhyohasis. This 

 genus is peculiar in having an inferior calyx, but a corolla united to 

 the ovary all the way up, together with epigynous stamens. A third 

 2)art of the memoir relates to plants collected in various parts of the 

 island-continent during the nineteenth century. Among the col- 

 lectors of these special mention was made of Allan Cunningham, 

 Rev. T. S. Lea, George Maxwell, and lastly of John Gilbert, among 

 whose plants have been identified specimens of the recently described 

 Psammomoya clioretroides Diels. & Loesn., remarkable among Celas- 

 traceiB for its leafless habit. Gilbert explored in Queensland and West 

 Australia for Gould, the ornithologist, but also did good botanical 

 collecting ; he was killed by natives in 1845 near the Gulf of 

 Carpentaria. One new genus, Leptospermopsis, is proposed, differing 

 remarkably from Leptospermum, which it much resembles, in the 

 androecium. 



Science Progress for July contains a long *• article " by Mr. T. 

 G. Hill on "The Water-Economy of Maritime Plants,"" dealing 

 especially with the absorption and transpiration of water by halo- 

 philous plants, particularly by Salicor?iia and Siiceda. Dr. Winifred 

 Brenchley has an " essay " — the reason for the distinction between 

 articles and essays is not obvious — on " The Uses of Weeds and Wild 

 Plants," in which a great deal of information is brought together : 

 the writer's acquaintance with recent British botanical literature does 

 not seem to be extensive, as the authors chietl}^ referred to are Hogg 

 and Johnson (1863), C. P. Johnson (1861-2), Anne Pratt, Wood- 

 ville (1790-92), and Wilson (1847). Under "Recent Advances in 

 Science," Dr. E. J. Salisbury summarizes papers published in various 

 departments of Botany — the paragraphing might be improved — 

 with the exception of Plant Physiology, which is undertaken by 

 Mr. Ingvar Jorgensen. The singularly useless page-headings, to 

 which M'e have already called attention, are continued, so we must 

 assume they have some justification not obvious to the ordinary 

 reader. 



The Journal of Genetics for June contains two botanical papers : 

 one, by E. J. Collins, on " Sex Segregation in the Brj^ophyta," based 

 upon the ]wpers of El. and Em. Marchal, but with nmch additional 

 evidence, and a plate : the other on " Double P'lowers and Sex- 

 Linkage in Bryonia,'''' by Mr. Bateson and Ida Sutton, containing a 

 series of observations and exi)eriments on M. Davisii, of which a 

 coloured jjlate is given.
