by Dr. Roscoe Pound and Mr. F. E. Clements. The first volume, now in 
press, will comprise about 350 pages and will be sold for $2.00. ‘The work

orms, habitat groups, plant formations, etc.” The publishers are Jacob

THE DIVISION OF BoTAny of the Department of Agriculture has pub- 
lished a bulletin (no. 10) calling attention to three new cruciferous weeds 
which have been reported from several new localities in the northern United 
States and Canada during the past four years, in some places having already 
become aggressive weeds. Although confined as yet to comparatively small 
areas, and having caused thus far but little damage in this country, the fact 
that they are spreading in grain fields, meadows, and cultivated lands, and 
also that they are weeds in the fields of western Europe, are reasons enough 
for warning the farmers. The plants are Lerteroa incana(L.) DC., Conringia 
orientalis (L.) Andrz., and Neslia paniculata (L..) Desf.
