Flora of Australia: 149 



Willdenow, 1793. p. 273, is usually referred to as a synonym to 

 Marlea begoniifolia, Roxb. , but since Loureiro describes it as having 

 the corolla inferior and the drupe superior, it cannot belong to this 

 genus at all, and has become a lost name without an owner. It is 

 not advisable to use lost names of this kind in founding new genera,, 

 but it is quite another matter to suppress a generic name attached 

 to well-defined species because 12 years earlier the name was applied 

 to a species of plant which cannot now be identified. 



The true history of the names of Stylidium and Candollea appears 

 to be the reverse of that given. Swartz published the name of 

 Stylidium in 1805 (Willdenow spec., PI. IV. (1805). 146), and at a 

 later date, 1807, repeats it (Magaz. Ges. Naturf. Fr. Berlin. I., 

 1807, p. 48). 



In the same year (1805) Labillardiere published the names Can- 

 dollea (Candolleaceae) for the same genus and order. Finding 

 that Swartz' s name had priority, Labillardiere then used the 

 name Candollea in the following year for a genus of Dilleniaceae, 

 now submerged in Hibbertia. 



Apart from the fact that nearly all the species of the genus have 

 been described under the name of Stylidium, namely, 90, as com- 

 pared with 9, there are no valid reasons for changing the namcj 

 adopted by Bentham and by R. Brown. I have gone fully into this 

 matter because of the confusion likely to occur, if the plants known 

 as Stylidium in Victoria are to be named Candollea in New South Wales. 



Tricholaena Teneriffak, Pari. " Red Natal Grass." (Gramineae). 

 This South African grass was introduced into Queensland many 

 years ago, and has there become fully naturalised. It has since 

 been carried to Victoria, and grows well at Mortlake and in the 

 Western District, where it is now naturalised. It is of some value 

 as a pasture grass, particularly in dry soils, being somewhat drought 

 resistant, but is by no means in the first rank as a pasture grass, 

 and is apt to become a troublesome weed in gardens and cultivated 

 ground. It is not suitable for a pasture grass in a rotation series, 

 where pasture follows cultivation. 



Zygophyllum ovatum, Ewart and White. (Zygophyllaceae). 



Alawoona (Trans-Murray Scrub), October, 1915, and Poochera, 

 Eyre's Peninsula, South Australia, J. M. Black, November, 1915. 



This species was first described from West Australian specimens, 

 then afterwards found in Victoria, and now in South Australia,, 

 thus bridging the geographical gap in distribution.
