GENERAL NOTES.

Some Abnormal Rudbeckias,— While botanizing in Central Arkansas last 
summer, my attention was called to a patch of Rudbeckia hirta. There ba 
about 50 plants in bloom, and in at least half of the heads more or less 0 4 
ray flowers were quilled. Sometimes only one ray in the head was arte ; 
in other heads several, and in quite a number of heads all the rays were quil fd 
Normal and abnormal heads occurred on the same plant. Some of the plants 
bore several heads, all of which were abnormal. The abnormal flowers were 
generally shorter than the normal. There was a great difference in the eects 
of quilling even in the same head, varying from a mere ring at the base a 
tube extending nearly to the top. The end of the ray was usually Bei ’ 
asin the normal form. The plants were normal in height and had oe 
stems and leaves. I am unable to account for this general teratological disp si 
or to assign a reason why normal and abnormal plants were growing eT 
side, much less to account for normal and abnormal heads occurring 0D 
same plant.—F, L. Harvey, Fayetteville, Ark. 
Cross-pollination in Vinea minor.—Le Maout and Decaisne say _ 
Vinea minor the “ pollen is granular, appli _ :

the neighborhood of stigma and anthers, mee 
nation seems at least to be the presumption. .
