Seedlings grown from fresh seed are much more resistant than those from older 
seed. By different experimentation they confirm the findings of other observers 
as to the power of calcium salts (they — of sulfate) to offset the toxic action 
of magnesium and sodium salts.—C. R. 
Edwin James.—Students of taxonomy will be interested in a recent paper by 
PAMMEL,*7 which gives an account of Dr. James, whose name is so intimately 
associated with the early explorations of the Rocky Mountain region. Not only 
numerous plants, but also a mountain peak bears his name, though the latter is 
now better known as Pike’s Peak. Through papers found in the Parry herbarium, 
local biographical sketches, and information obtained directly from relatives, 
a very satisfactory account has been prepared, and the personality of JAMES is 
thus rescued for botanists—J. M. C. 
Conifers of China.—The late Maxwett T. Masters left a paper on the dis- 
tribution of conifers in China, which has just been published.4* The total number 
of species known from China at the time of writing (June 20, 1907), inclusive of 
Formosa, was 87, distributed among 23 genera. In one table China and Japan 
are compared; the former containing 87 species, of which 42 are peculiar; th 
latter 48 species, of which 15 are peculiar. A large table shows the distribution of 
all the native species of China in the various regions of the empire as well as in 
neighboring countries.—J. M 
Nuclear division in Basidiobolus.—Oxive4? has studied nuclear and cell 
division both in the beaks and in the tative cells of Basidiobolus. The spindle 
is broad, cylindrical, barrel-shaped, and intranuclear. At the equatorial plate 
stage it shows three darkly staining regions, the chromatin plate at the center 
and two pole plates at the ends. The wall is formed as a ring, which begins at 
the periphery of the cell and closes in like an iris diaphragm, as in many algae, 
a mode of growth quite different from that described by FarRcHILp in 1897 
CHARLES J. CHAMBERLAIN. 
Variegation and infectious chlorosis.—Those who are interested in these 
problems will find useful an extensive paper by LinDEMUTH,*° which embodies 
a precise and comprehensive exposition of the results of his studies on variegation, 
which go back as far as 1870, and have been continued with more or Jess vigor to
