Morphology of wheat.—JENSEN” has investigated certain strains of wheat 
and the result is perhaps our fullest account of the morphology of this important 
plant. The subjects considered are development of spike and flower, of micro- 
spore and male gametophyte, of megaspore and female gemetophyte, fertili- 
zation and development of embryo, and endosperm. An interesting record is 
that fertilization occurred from 32 to 40 hours after pollination—J. M M. C. 
Intrafascicular cambium in monocotyledons.—Mrs. ARBER"™ has added to 
' her previous observations” of rere cambium in monocotyledons 
other observations which inclu raceae, Dioscoreaceae, Iridaceae, and 
Potamogetonaceae. Such sdathibeec is now known to occur in “all but two of 
the cohorts into which ENGLER divides the monocotyledons; the exceptions 
are the Triuridales and the Synanthae.’”’—J. M. C 
Seed position and growth.—It has been found that bean seeds planted 
with the eye up give a somewhat lower degree of germination and growth than 
when the seed lies flat or is placed eye down.’ This seems to show that the 
common practice of dropping seeds flat upon the soil when planting gives 
results that are satisfactory —Gro. D. FULLER.
