Personal Investigations 
The most intensive as well as extensive studies of the 
year have been directed to various lines of investigation 
with Cichorium Intybus. The results of the previous 
years’ study on the self- and cross-compatibilities and in- 
compatibilities revealed in fertility and sterility were 
published in August in the Memoirs of the New York 
Botanical Garden, volume 6. During the past summer 
these studies oo been vigorously prosecuted with a later 
generation of pedigreed cultures. About 5,500 controlled 
self-pollinations were made on as many heads of 549 plants 
and the results of seed production determined. A consid- 
erable number of cross-pollinations was also made. Much 
data were also obtained from these cultures on the isola- 
tion of vegetative types by pure line breeding, on the 
heredity of flower-color, and on the behavior of fasciation. 
The cultures of chicory were also utilized for a continu- 
ation of a statistical study of flower-number, which has now 
been continuously prosecuted for five years. A total of 
515 plants were involved in these studies during 1916. In 
obtaining these data, Miss Helene M. Boas, Mr. M. V. 
Reed, and the writer codperated. The granting of a 
scholarship for two months to Mr. Reed made his par- 
ticipation in these studies possible and thereby greatly 
facilitated their progress. Miss Boas has continued as 
laboratory assistant during the year and a considerable 
portion of her time has been taken in collecting and com- 
piling the data. She will collaborate with me in the pub- 
lication of the results, and the manuscript for such publi- 
cation is now in preparation. 
New cultures of Hibiscus have been grown and consider- 
able data obtained bearing on the polymorphism of 
Hibiscus Moscheutos, on the general heredity of H. ocu- 
liroseus (especially of the dwarf form), and of the variation 
resulting among the progeny of various varietal and specific 
hybrids. The development of internal flowers (rudimen- 
tary flowers enclosed in the pistil and pod) in H. ocultroseus
