14. Rhodode7idre(e Asm Orientalis: a paper by Maximo 

 cently issued (1870) as the 9th fasciculus of the IGtli voluii 

 Memoirs of the Imperial Academy of Sciences of St Pott 

 illustrated by 4 plates, imp. 4to. In the commeueeiiunt 

 elaborate and very interesting article, Maximowicz txphi 

 the name Bododendrem is preferred to Rhodorem because' tl 

 lihodora is a mere quasi-abnormal form of a section of PJ 

 dron, taking this genus, as he does, in the most eiilarux 

 Also that the characters of scaly and not scaly binls is i 

 pk'tely available, as was thought, for dividing the groups i 

 Iribes as Ivlotzscli proposed. We have been aceustnnu 

 tliis character in a subordinate way, Avhen it is very \ 

 aware that both modes occur in some genera, sucli as Vm 

 The main distinction between his PhyUodocei^ and his / 

 drendreoe is that of the seed, with a close testa in the form 

 form in the latter. Among the genera of the former 1 

 Rhodothauinus, founded on Rhododendron C/tamartsti 

 point which most nearly concerns us is that, notwithstam 

 Californian species which Ave regard as uniting tliem, 3Iax 

 keeps up both Bryanthus and Phyllodoce, the former of 

 original plant only, the corolla of which he newly dts. 

 "ad basin 4-partita, horizontaliter patens." He also red:
