A NEW BERTYA 151 



caulon in his herbarium. M. de Candolle was good enough to do 

 this, with the result that he has no doubt about the correctness 

 of his grandfather's surmise. Under these circumstances, M. 

 Pterocaulon being unknown from India, one must conclude that 

 Linnaeus was mistaken in supposing C. decurrens to be a native 

 of that country. 



The plant appears to have become established in Mauritius, 

 and in connection with that fact has received the name of 

 Pterocaulon Bojeri Baker.''' The synonymy therefore stands as 

 follows : — 

 Pterocaulon decurrens, comb. nov. '' 



Conyza decurrens Linn. Sp. PI. ed. ii. 1206 (1763). 



Monenteles Pterocaulon DC. Prod. v. 455 (1836). 



Pterocaulon Bojeri Baker Fl. Maur. 164 (1877). 



Besides Bojer's material, the species is represented in the 

 National Herbarium by the following : — North-west Madagascar, 

 Pasandava Bay ; Ilildehrandt, 3014. Central Madagascar ; P^ev. 

 B. Baron, 1321. North Madagascar; ibid., 6461.

A NEW BEETYA. 

 By E. a. DiJMMER. 



While engaged on the Conifers of the Lindley Herbarium, 

 Cambridge, my attention was drawn to a specimen included 

 among the Podocarps of that collection, which was doubtfully 

 referred to that genus by Lindley. This plant was collected by 

 Eraser in the Barrens, north of Arbuthnot's Eange, in Australia, 

 and turns out to be an undescribed species of Bertya, of the 

 natural order Eujjhorbiacece, for which therefore the name B. 

 neglecta is proposed. Bertya, a genus comprising approximately 

 fourteen species, is limited to Australia and the adjacent island 

 of Tasmania, and includes a series of shrubs, some of an ericoid 

 aspect, of which B. gummifera merits cultural attention. 



The species under consideration, of which the female flowers 

 are as yet unknown, has the superficies of B. rosmarinifolia, but 

 is immediately distinguished from it by its more glabrescent 

 character, the presence of minute spinules which clothe the twigs 

 and the leaves, the relatively larger male flowers and the ten 

 larger bracts which subtend them. 



Bertya neglecta, sp. nov. A bushy heath-like shrub. Cur- 

 rent year's twigs subumbellately disposed, erect, straight and 



Fl. Maur. 164.
