fication on the groiincl of structure, appears to lie in the acceptance of 

 BaiUon's suggested name, giving up that of the authors of the Flora 

 Indica. 



The synonymy of Guatteria is further complicated by the fact that 

 a large number of species with valvato aestivation were referred to it 

 by Wallich and others. These, however, were separated by Hook fil. and 

 Thorns, by whom the genus Polyal/hia was formed for their recep- 

 tion. Sir Joseph Hooker refers to Cananga, not only the species G. 

 odorata, but another named G. virgatd. The latter plant appears to me, 

 in tlie light of full material recently received, to be a typical Gyathocalyx, 

 and to that genus I have ventured to remove it. A tliii-d species doubt- 

 fully referred to the genus GanaiKja under the specific name monosperma, 

 appears to me from the description (I have seen no good specimen) to 

 be so doubtful that I exclude it altogether. The seeds both of this 

 species and of G. Odoratum are peculiar ; I quote the following excel- 

 lent description of those of G. odoratum from Hooker fil. and Thomson's 

 Flora Indica, page 130. " The seeds are pitted like those of the section 

 Kentia of Melodorum, and of some Cucurbit acece ; and the inner surface 

 of the brownish-yellow, brittle testa is covered with sharp tubercles, 

 which penetrate into the albumen, taking the place of the flat plates 

 which are found in the rest of the order."
