40 The Botanical Gazette. { January. 
Mr. J. N. Rose desires both living and herbarium specimens of 
Tradescantia and Commelina from all parts of the United States. He 
is especially anxious for roots and flowering specimens of the various 
forms of T. Virginiana. He will name and return specimens when 
desired. Franks for the sending of specimens will be furnished on 
application. 
GARDEN AND Forest continues to publish fine illustrations of our 
interesting native plants. Among the late ones we note (Dec. 12th) 
Quercus Garryana of the Pacific slope, and (Dec. 19th) the “Muskeag 
Spruce,” characteristic of the forest lakes of Minnesota. In the latter 
number Mr. Charles H. Coe gives an interesting illustrated account 
of the so-called “Florida sea beans,” which he says belong to four gen- 
era, only one of which grows in this country. 
THE PUBLICATION of Science has been resumed for the third time, by 
the recent publication of number 1 of volume I of a new series, under 
the direction of a committee of eighteen, made up of representatives 
from different editorial sciences in rather unequal fashion. The de 
partment of botany is in charge of Dr. N. L. Britton. The list of 
names given is a very strong one, and if the financial backing 1S 8 
strong as the scientific the journal should be very successful. We wish 
scribed two new species. f the thirteen species enumerated M. 
Vesque had only made note of six. 
AT A MEETING of the Linnean Society last December, as reported 
Gardener's Chronicle (Dec. 15th), Sir Dietrich Brandis presented 
or this reason adequate material for determinations has bee? 
very difficult to secure, and has only lately been at all full. | 840 
Korthals described 34 species; DeCandolle, in 1868, described 126; 
Thistleton Dyer, in 1874, estimated the number at 170. Sir D. Brandi 
now estimates that there are 320 species belonging to 16 genera. 
ROFESSOR E. L. GREENE continues his “Observations on the Ce 
posite” in the current number of Zrythea (Jan.). The maze of astero! 
forms are further considered and new generic lines proposed. Main: 
proposed as new genera; the first to contain Xanthocephalum tomer 
tellum Robinson; the second, Solidago pumila T. & G.; the 
various forms of the Mexican and Central American plants that 
een referred to Aplopappus stoloniferus.
