232 Alfred J. Ewart : Flora of Australia. 



those under Ptilotus should be put under Trichinium, whilst those 

 under Trichinium should be placed under Ptilotus. F. Mueller, 

 in his Census of Australian Plants, placed Trichinium as a sub- 

 genus of Ptilotus. This arrangement is followed in Engler's 

 Pflanzen Familien, and Maiden's Census of New South Wales 

 Plants. In the Flora Australiensis, Bentham keeps them separate, 

 but considers that if they were to be united it would be preferable 

 to adopt Trichinium, as it contains the larger number of species, 

 and would therefore cause the least confusion with the nomen- 

 clature of the species. 



For the sake of convenience they were kept separate in the 

 Flora of the Northern Territory, and the generic names were 

 accidentally transposed. 



Sclekochloa dura, Beauv. "Hard Grass." (Gramineae). 



Longerenong Agricultural College grounds, Dooen, Victoria, A. 

 C. Drevermann, October, 1920. 



A native of Europe, Asia and Africa. An exotic not yet 

 sufficiently established to be considered naturalised. It is two 

 small to be of much use as a pasture grass. 



Sklaginki.la stolonifrka, Spring. "Creeping Selaginella" or 

 " Cubmoss." (Selaginellaceae). 



Malleson's Glen, Don River, Victoria, F. G. A. Barnard. 

 26/4/1920. 



This well-known greenhouse plant, a native of the West Indies, 

 has made its appearance in a fairly large quantity in the above 

 district. It had probably originated by wind-born spores from 

 the garden of Mr. A. Agnew close by. It may be classed as an 

 exotic not sufficiently established to be considered naturalised. 



Suriana maritima, L. (Simarubaceae). 



Goldburn Island, Northern Territory, M. Holtz, No. 22, March, 

 1911. 



This plant is a low bushy shrub, 4 to 6 ft. high, growing at 

 high water mark pn the Island. Flowers yellow.
