The collection submitted to us contains about 800 species, but 

 the material available has in many instances among the larger 

 genera not been adequate for specific determination, hence the 

 number of actually recorded species is only about 700. A few 

 presumable novelties are reserved for further study. 



Where no collector's name is appended to a geographic record, 

 that of Mr. Helms is to be considered to have been omitted. 

 The names of by-workers are however given, of these may be 

 mentioned Mr. P. A. Gwynne, who collected from Fraser Range 

 to Esperance Bay and to whose zeal we owe an interesting sup- 

 plementary collection, and to Mr. D. Gumming, who accompanied 

 Mr. Wells on a flying-survey from Annean Station on the Upper 

 Murchison-river to the eastward as far as long. 124° 31', and 

 gathered 55 species, but of these only three are supplementary to 

 the main collection. 



The geographic positions of the recorded stations are indicated 

 on the geological map accompanying this volume. The word 

 " Camp " is generally abbreviated in the text of tliis report to 

 " C," thus C. 22 stands for Camp 22. 



DILLENIACEvE. 



HiBBKRTiA GLABERRIMA, F. V. M. S.A., EvBrard Range, at 

 2,000 ft. elevation. 



HiBBEitTiA ROSTELLATA, TuTcz. W.A., near Boorabin. The 

 stamens are disconnected, but by gradual turgescence of the 

 maturing fruitlets, may be pushed into clusters of threes, yet 

 without forming real bundles by any concrescence of filaments. 

 Ovularies occasionally only four. To .judge from the very im- 

 perfect but authentic material in the Melbourne Herbarium, 

 Candollea unainata, Bentham, belongs to this species. The 

 externally very similar H. recurvi/olia, Bentham, has lately been 

 found inland as far as Youndegin by Miss Alice Eaton, and near 

 P;irker's Range by Mr. Edwin Merrall. 



Var. BECTIFOLIA. W.A., Victoria Desert (C. 59),on sandhills. 

 This plant has almost straight or only slightly curved leaves, and 

 with peduncles about as long as the calyx, but otherwise not 

 different from 7/. rostellata ; the mature carpels are smooth 

 and shining, each with one ripe reniform seed. Precisely the 

 same form was gathered in (3iles' Third Expedition near Victoria 

 Spring. 



HiBBEETiA C4L0MERATA, Bentham. W.A., between Red Hill 

 and Yilgarn. 



HiBBERTiA HuTTii, F. c. M. W.A., between Red Hill and 

 Yilgarn.
