(42) 
and almost entirely cleistogamous. Seed progeny of these 
will be grown to test the inheritance of these variations. 
The severe winter of 1913-1914 killed about 1,500 
plants of Hibiscus, thereby interfering with the breeding 
experiments in this genus. New plantings were again 
made to cover the various lines of experiments planned. A 
considerable number of these young plants bloomed late 
in the season and I was able to obtain some seed for a new 
generation. Several new types have appeared in the 
cultures. One which is of special interest appears to be a 
dwarf mutant of the species Hibiscus oculiroseus. It was 
also determined that the first generation hybrids between 
white-flowered forms of H. Moscheutos and H. oculiroseus 
were almost identical to the latter in flower color, but 
different in pod character. 
Certain phases of the study of bud-variation in Coleus 
have been completed and the results are now prepared for 
publication. These investigations will be continued and 
somewhat extended, especially in regard to the behavior 
of seed progenies. 
First generations of hybrids involving several species of 
Carex are now growing and should bloom during the coming 
year. 
During the spring, data were taken on variations that 
appeared in the different types of tulips grown for display 
here. A bed of tulips derived from bulbs of plants showing 
variation has been planted in the experimental garden for 
further special observation. 
The winter months have been employed in working up 
data and in pursuing cytological studies. 
The appointment of Miss Helene Boas as laboratory 
assistant has aided the progress of various investigations. 
Miss Boas has been given charge of the statistical data 
regarding the inheritance of flower number in Cichorium. 
She has also made a general survey of the variegated plants 
grown here with special reference to the types and to their 
distribution in various families.
