SMALL" has described a new species of Anamomis (A. Simsonii) from the 
Everglades of Florida. The only other species of the genus known to grow in 
the United States is the endemic 4. dicrana, which occurs in a different part 
of Florida. 
SMITH,'s in continuation of his studies of Malayan — has described 
66 new species, representing 24 genera. Basigyne is described as a new genus. 
SturGis® has described new species of Myxomycetes, chiefly from Colo- 
rado, in Physarum (2), Didymium, and Enteridium. 
SMITH,” in continuation of his studies of Lupinus, has monographed the 
Microcarpi, recognizing 6 species, although 14 specific names have been pub- 
lished. The discussion of L. densiflorus with its varieties is reserved for a later 
paper. The variable species of the 5 considered is L. subvexus, 8 new varieties 
being described. 
WERNHAM,® in continuation of his studies of tropical American Rubiaceae, 
has described a new genus (Raritebe) from Colombia, resembling Bertiera, the 
new name being an anagram of the rgb oe ew species are also described in 
Psychotria (2) and Palicourea (4).—J. 
Evaporation and soil moisture studies.—The increasing amount of atten- 
tion given to quantitative studies of the moisture factors of various plant com- 
munities is shown by several recent papers. Conspicuous among them is one 
by WEAVER,” reviewed elsewhere in this journal, in which he reports measure- 
ments of the evaporating power of the air and of soil moisture in both forest 
and grassland associations of southeastern Washington, leading to the con- 
succession, the climax community being the most mesophytic in both respects. 
With regard to the former factor it is further stated that “‘a study of the differ- 
ences of the rate of evaporation in the various plant communities shows that
