Neiv Victorian Haloragis and Genus Pluchea. ]35 



H. vudis is often erect, but seems never a tall species; the 

 branch lots are remarkably robust ; the leaves have a particu- 

 larly thick pale margin. 



H. nodidosa was gathered by the writer at the Greenough 

 and Irwin Rivers ; eastward, it extends to Israelite Bay 

 (Miss Brooke), and Esperance Bay (Dempster). 



H. j)aniculata occurs on the Collier, Preston, and 

 Blackwood Rivers (F. v. M.) 



Halokagis pycnostachya. 



Erect, rather dwarf; beset with spreading soft hairlets, 

 leaves firm from lanceolar to rhomboid-ovate, flat, serrulated, 

 almost sessile, the lower opposite, the upper scattered ; flowers 

 in dense terminal spikes ; bracts ovate-lanceolai", foliaceous, 

 about as lonoj as the flowers or someAvhat longer ; flowers 

 singly sessile in each axil ; calyx-lobes four, almost deltoid, 

 much shorter than the four outside short hairy petals ; 

 stamens eight ; stigmas conspicuously bearded ; fruit small, 

 subtle-downy, somewhat quadi'angular, rough from two 

 transverse rows of minute granules, above the upper row 

 contracted and streaked, usually one-celled and one-seeded. 

 Near Israelite Bay (Miss Brooke). Differs from H. conferti- 

 folia in the longer and less dense vestiture, in much larger 

 and less crowded stem-leaves, in broader and shorter calyx- 

 lobes, in more noduligerous and upwards more conspicuously 

 contracted fruits, the latter reminding of those of H. nodulosa. 



H. heterophylla must include also H. ceratophylla, accord- 

 ing to the respective drawings by De Caisne, and by Bauer; 

 it belongs more particularly to the coast-regions, while 

 H. aspera pertains chiefly to the inland country, and thus 

 not occurs in Tasmania. Further, the H. pinnatifida (A. Gr. 

 non J. H.) seems a state of H. heterophylla ; Endlicher 

 derived his plant from Shoal water Bay ; his description 

 accords fully with the earlier one given by Brogniart, except 

 the remark on the supposed unisex uality of individual 

 plants, pronounced evidently from imperfect material. Our 

 collections show this species to inhabit the following 

 localities beyond those already recorded : Gordon River 

 (Miss Oakden), Mount Lofty (Tepper), Barossa Range 

 (Dr. Behr), Wannon River (Sullivan), Emu and Ores wick 

 Creek (Rev. W. Whan), Loddon, You Yangs, Snowy and 

 Hume Rivers (F. v. M.), Genoa (Baeuerlen), Paramatta
