waters much as the peculiar alpine floras of the north temperate 

 zone were left stranded by the recession of the ghiciers. Two sets 

 of facts gave point to this fascinating suggestion : first, the Blue 

 Green alga3 of the hotter waters are nearly the same everywhere; 

 second, the cell structure of these algj:e is tkr simpler than that of 

 any other organism. The address, under the title of "Life in Hot 

 Waters," may be found in the University Chronicle, of the Univer- 

 sity of California, for June, 1898. 



A COPY of Strasburger, Noll, Schenk and Schimper's Text- 

 book of Botany, published by MacMillan & Co., New York, has 

 been sent us by Mr. E. F. Goodyear, their Pacific Coast agent, at 

 327 Sausome Street, San Francisco. We have also received from 

 B. R. Baumgardt & Co., Los Angeles, California, a botanical reader 

 for children, by Alice Merritt Davidson, entitled "California Plants 

 in Their Homes," which we expect to notice further in a later issue. 



Two Californian species of Calochortus have recently been figured 

 in English periodicals, C. chwalus, m Curtis' Botanical Magazine 

 for July, 1898, and C. Pardyi, in the Gardeners' Chronicle, xxiii 

 (ser. 8), 395, fig. 147, June 25, 1898. The August, 1898, number 

 of the former periodical also contained an illustration (t. 7610) of 

 Ledum glandulosum. 



Mr. C, G. Lloyd, of Cincinnati, Ohio, has sent us Nos. 23 and 

 24 of "Photogravures of American Fungi," which are most excel- 

 lent habit pictures of a specimen of Folyporus Berkelayi two and 

 one-fourth feet across. Issues No. 25 and No, 26 present examples 

 of Folyporus umbellatus and strobilomyces strobilaceus, and are 

 equally creditable. 



The Botanical Seminary of the University of California is 

 now in the second year of its series of discussions concerning hered- 

 ity. Two papers read before it during the present college year 

 have been published in the University Chronicle and reprinted as 

 "Contributions from the Botanical Seminary of the University of 

 California." The titles are: '' Problems of Heredity," by W. J. V. 

 Osterhout; and " Unity in Variability," by Hugo de Vries, translated 

 by H. T. A. Hus.
