304 lewton: the Australian fugosias 



1789 as a substitute for Cienfuegosia, published three years 

 earlier by Cavanilles,^ who gave the name in honor of Bernard 

 Cienfuegos, a Spanish botanist of the sixteenth century, to a 

 plant collected by Adanson in Senegal. In spite of a partial 

 restoration of the older name by Willdenow'' and by Sprengel,' 

 and its complete restoration by Bartling;^ Persoon,^ DeCan- 

 dolle^^ and Endhcher" used Jussieu's abridged form of Cava- 

 nilles' name and were followed by later systematic writers, espe- 

 cially Bentham, Hooker, and von Mueller. 



The Australian shrubs described by von Mueller and by 

 Bentham as species of Fugosia, when compared with the Amer- 

 ican and African plants assigned to that genus, appear so distinct 

 in habit and gross anatomy as to warrant their being excluded 

 from the genus, the type species of which is, as above stated, a 

 native of Africa. Furthermore, the Australian species are easily 

 divisible into two groups, already indicated in the Flora Aus- 

 traliensis. Even a very cursory examination of the plants is 

 sufficient to convince one that these two groups have very little 

 in common. In the writer's view they represent two distinct 

 genera, here discussed separately. 



THE GENUS NOTOXYLINON 



The larger group of Australian Fugosias comprises eight 

 species: F. australis Benth., F. flaviflora von MuelL, F. lati- 

 folia Benth., F. populifolia Benth., F. robinsonii von MuelL, F. 

 thespesioides Benth., F. punctata Benth., and F. pedata Bailey; 

 which have all, at one time or another, excepting the last, been 

 placed in the genera Hibiscus, Cienfuegosia, or Gossypium. They 

 differ from the African and American species of Fugosia, as the 

 genus is commonly defined, in having the involucre 3-bracted and 

 the black oil glands not restricted to the sepals and capsules but
