Aster —In 1902+ E.S. Burcess published a “History of Pre-Clusian Botany 
in its relation to Aster;’’ and now a second paper on Aster has appeared,’ which 
deals with the “Biotian Asters.’”” Under the head of variation, specific limits in 
the genus are discussed; also normal characters and the comparative variability 
of organs. There is no group of flowering plants in which such a discussion 
would seem more difficult. A systematic treatment of the species is also begun, 
84 species being presented with great fullness, 58 of which are published for the 
first time; me 10 Sukepees and about 250 subordinate forms are character- 
ized.—J. M 
Festuca.—C. V. Piper® has published a monograph of the North American 
species of Festuca, recognizing 34 species, and characterizing 3 of them as new. 
A third subgenus is added to Vulpia and Eufestuca, to include F. conjinis Vasey, 
and is called Hesperochloa. There are also notes on several Mexican species 
including descriptions of 2 new species. A new word is added to the terminology 
of grasses. The word “glume” is restricted to the “empty glumes;’’ while 
the “lower palet” or “outer palet” or Se glume” of authors is the Jemma, 
a Greek word meaning husk or scale-—J. M
