Prain, D., The gen US Ceratostigma. (Journal of Botany. 

 Vol. XLIV. No. 517. 1900. p. 4—8.) 



The genus Ceratostigma was founded by Bunge in 1834 on a 

 plant, collected in the neighbourhood of Pekin, about a quaiter of a 

 Century before that Salt had described Pliitnbago eglandiilosa from the 

 Abyssinian highlands, which was subsequentiy (in 1842) together with 

 another closely allied Abyssinian form made the basis of a distinct 

 genus Valoradia by Höchste tter. Boissier (in DC. Prod. Xll. 1848. 

 p. 694) showed that Ceratostigma and Valoradia were congeneric, and 

 used the latter name, although most later writers adopted Bunge 's 

 name. Other forms have since been found in Somaliland, Indo- 

 China, Western China to Eastern Tibet, Eastern Himalaya, 

 and Tibet, so that the break in the area, occupied by Ceratostigma is 

 less extensive than seemed formerly to be the case. The author then 

 proceeds to give the diagnosis of the genus and its seven species; the 

 calyx-segments were found to have only one ntrve and not three, as 

 stated in the Gen. Plant., nor a pair of marginal nerves, as described 

 by Boissier. The species described are the foUowing:

 distincta^ squamis numerosis acicularibus insignis) (Tibet); C. minus

 tomento densiore, floribus manifeste majoribus, capitulis omnibus termi- 

 nalibus subterminalibusve nullis plane axiliaribus) (Somalia).
