the flower of Swertia ener varies to white from its usual 
hilac ; and that Dr. T. Cooke has fully parasenied Ophelia mai 
under the name adopted in the Flora of British India of S. corym- 
bosa, var., Lawii (Flora of the Presidency of Bombay, ii., 1904, 
p. 194). He states the petals to be white with blue veins, mean- 
ing undoubtedly lilac veins: this is just as I have myself found it. 
The first specimens of the group found in China were described 
by Hance as ar toad ia vacillans in the Annales des —- Naturelle, 
Ser. 5, v. (1866), p. 229. Maximowiez, commentin iA 
of Worthan eae referred to Hance’s plant as Sw vetia vacillans 
in the Mélanges stat As be of St. Petersburg Academy, xi.,. 
Hance, later, having received more specimens which he 
wished to cite (Journal of Biokany, 1885, P 326) adopted Maxim, 
owicz’s name, which persis sts in Forbes and Hemsley’s Index 
from Passi Cerlon. The result of critically turning over oe 
‘much material is a Maat slight modification of the scheme 0
