For the scientific part of the meeting Mr. R. Bamford of 
Columbia University presented a paper entitled “Cytological Stud- 
ies of Sterile Violet Hybrids.” An abstract, kindly furnished by 
Mr. Bamford, follows. : 
A detailed description was given of morphological characters, 
pollen, chromosome numbers, and meiotic divisions preceding 
microspore formation of four sterile F, violet hybrids produced 
by cross pollinations. The hybrids are as follows: 
V. incognita Brainerd, x lanceolata L. 
V. pallens (Banks) Brainerd x cucullata Ait. 
V. silvatica Fries x striata Ait. 
V. elatior Fries x striata Ait. 
(female parent given first in each case) 
The results indicate that chromosome numbers per $° bgt 
merely an accompanying feature of the phenomena of fertility 
and sterility. The cell as the fundamental, vital unit is stressed,
