CURRENT LITERATURE. 
MINOR NOTICES. 
MEssRs. SEYMOUR AND EARLE‘ have issued a supplement to their series 
of economic fungi. It consists of forty packets of dried specimens, ten being 
species of Peronospora and Synchytrium marked 4, and thirty of various 
Uredinee marked B. The system of numbering is not explained, and, in 
fact, the printed matter accompanying the distribution consists only of a 
folded leaf bearing the title page and contents. N early a score of botanists 
have contributed to this first fascicle. The specimens are excellent, and the 
publication will doubtless meet with favor.—J. C. A. 
NOTES FOR STUDENTS. 
BULLETINS ON WEEDS are issued by the experiment stations from time to 
time and add greatly to a knowledge of the habits and distribution of this 
class of plants. A recent paper by H. Garman (Ky. no. 70, pp. 99-107, Aes. 
2) on “Woolly mullein (Verbascum Philomoides) in Kentucky” brings into 
notice a new roadside and riverside weed. At present it has invaded an area 
of about fifty square miles in the vicinity of Green river. It is a weed of 
waste ground rather than of cultivated fields. : 
“A first Ohio weed manual,” by A. D. Selby (Ohio no. 83, pp. 247-400, 
Jigs. 1-71), forms a thick bulletin and gives information regarding 279 spe- 
cies of plants that should be subdued by the cultivator. Although the species 
are arranged in the usual systematic sequence, technical diagnoses are not 
employed, In their stead the striking features that would appeal to the 
untrained observer are clearly and simply set forth. Besides giving char- 
acters which assist in identifying the plant, the seeds are described so that 
they may be recognized when found in commercial seeds, and what is known 
regarding the noxious habits of the plants as well as practical methods of 
subduing them, form an important part of the presentation. The work closes 
with a tabulation of the distribution of roadside weeds in Ohio, from data 
furnished by 357 Correspondents. The bulletin is an admirable and service- 
able contribution to the literature of weeds.
