bees in this connection is recognized in some localities, and It 
would seem that growers of long stapled varieties might find bee- 
keeping a distinct advantage to the cotton crop . 
Cruciferous Root Vegetables 
Poole, C. F. 
1937. Improving the root vegetables. U. S. Dept. Agr. Yearbook 1937: 
300-325. 
p. 310: The cruciferous root vegetables — turnips, rutabagas . 
and radishes— have relatively large flowers, which are insect-polli- 
nated . 
Onion 
Jones, H. A* 
1937. Onion improvement. U. S. Dept. Agr. Yearbook 1937: 233-250. 
p. 239* Most of the pollen is shed between 9 a.m. and 5 p.m. 
Pollination is effected mainly by insects that go from flower to 
flower and visit the nectaries at the base of the three inner 
stamens . Interpollination among flowers of the same umbel is no 
.doubt of frequent occurrence, as the same insect has been observed 
to visit many flowers on an umbel before leaving. In the onion, 
however, cross-pollination is the rule. 
Pepper 
Odland, M. L., and Porter, A. N. 
1941. A study of natural crossing in peppers ( Capsicum frutescens ). 
Amer. Soc. Hort. Sci. Proc. 38: 585-582, tables. 
p. 588: The pepper flower is rather inconspicuous and non- 
• fragrant, a fact that would suggest pollination not very likely. 
Erwin . . . found that the flowers produced nectar and that insects 
did at times visit them. The writers are of the opinion that honey 
bees are largely responsible for the cross pollination that takes 
place . This insect has been found working on the pepper plant 
rather often. The presence of the bee is rather spasmodic, however . 
as they are found only on certain warm bright days. The presence of 
bees in the vicinity may have a bearing on the amount of cross polli- 
nation .

1945. Cross pollination of fibre flax. Bee World. 26:30-31. 
p. 30: Among all insects which pollinate flax flowers the 
honeybee occupies a significant place ... . The honeybee constitutes 
93.8 percent of all such insects.
