the study of fertilization in this species, for which I have 
material at hand. Considerable material was obtained 
during the spring from other species of Carex for more 
extended cytological studies in this genus. 
Regarding my study of the fungus Sclerotium rhizodes, 
I can report that this fungus has been found to be very 
abundant in the upper Hackensack meadows, where it is 
very destructive to Calamagrosiis canadensis. The presence 
of the fungus in this vicinity gives opportunity for continued 
search in the field for the perfect stage of this fungus which, 
at the present time, is not known. 
During the summer months my time was almost entirely 
devoted to experimental studies in plant breeding. us 
far I have worked with the following groups of plants: 
(1) Cichorium Intybus, wild white-flowered plants, wild 
blue-flowered plants, and plants grown from seed of culti- 
vated strains; (2) Verbascum Blaitaria, yellow-flowered and 
pitino ved plants; (3) Hibiscus militaris, H. Moscheutos, 
H. oculiroseus, and the hybrid H. oculiroseus * H. Mache 
tos, and (4) Carex stricta and Carex Goodnotit. 
The work of the past summer on these forms was in large 
measure preliminary and consisted chiefly in studying the 
vegetative characters, and in securing pedigreed seed from 
controlled self-fertilizations and cross fertilizations. The 
results obtained encourage continued experimentation with 
all these forms. 
In connection with the studies of Hibiscus several days 
were spent in southern New Jersey at Island Heights, where 
observations were made over large fields of wild Hibiscus 
Moscheutos, with special regard to the variability of this 
species. Several plants representing ranges in the vari- 
ability were shipped to the Garden and planted in the 
experimental garden for use in the breeding experiments. 
I hope to be able to make more extended observations of 
this sort in the field during the coming summer. 
Systematic observations have been made during the year 
on the phenomena of bud variation in Coleus Blumei.
