436 MR. F. N. WILLIAMS ON THE 
Turezaninow (1838), from the characters given, one would 
scarcely be justified in maintaining it as a genus distinct from 
Stellaria. Maximowiez, however, in a careful study of a series 
of specimens of Krascheninnikovia rupestris, indicates other cha- 
racters, such as the diverse type of the structure of the flowers 
found at the base of the stem in contact with the soil, as com- 
pared with those terminating the flowering stems. And on the 
characters brought together by Maximowiez its separation from 
Stellaria is certainly warranted. The plant described as Stellaria 
bulbosa, Wulf., in the ‘ Flora of British India ' is certainly to be 
referred to K. Davidi (and is a form of it), which is recorded by 
Franchet from the neighbouring province of Yun-nan (Delavay, 
n. 1035, 1884). Mr. Hemsley records the species elsewhere in 
China only from Jehol, in the province of Chih-li (David, 
n. 1924). Franchet also forbears to separate the genus from 
Stellaria, as he says:—“ L’ancien genre Krascheninnikovia est 
aujourd'hui rapporté aux Stellaria par presque tous les auteurs, 
bien qu'il ne soit pas moins nettement caracterisé que la plu- 
part des autres genres de Caryopbyllacces, maintenus plutót 
par habitude qu'en raison d'une valeur réelle."
