Personal Investigations 
The results of the studies of bud variation in Coleus, 
which have been in progress since 1911, have, during the 
year, been published by the Carnegie Institution of Wash- 
ington (Publication No. 218). Further studies are planned 
regarding seed progenies and the possibility of inducing 
variations. Chemical investigations of the pigments in- 
volved in the variegation are highly desirable and material 
for such study has been furnished to Dr. B. Horowitz, 
who is undertaking such a study under the direction of 
Professor W. J. Gies. 
Cultures of Verbascum Blattaria have been continued 
for the study of the heredity of flower color. A large 
number of fasciated plants appeared in the cultures that 
were held over winter; this development evidently being 
induced by conditions of growth. 
A third generation of pedigreed plants of Cichorium 
Intybus was grown during the year for a continuation of 
the investigation of self and cross sterility for which this 
plant is especially favorable. A report of the results thus 
far obtained was presented at the Twentieth Anniversary 
of the Garden and a complete report is now in preparation 
for publication in the near future. Statistical studies of 
the flower number in Cichorium were vigorously prosecuted 
during the summer, Miss Helene Boas, Mr. R. C. Faulwetter, 
Miss Friedolina Jud, and the writer participating in the work. 
Miss Boas has continued in the work of compiling this 
data, which we hope soon to report in complete form. 
By means of a mulch, the cultures of Hibiscus were suc- 
cessfully carried through the winter of 1914-1915. These 
bloomed profusely, giving data on the behavior of various 
types of F1 hybrids. The appearance of an interesting 
dwarf type of Hibiscus oculiroseus has been reported during 
the year (Bull. Torrey Bot. Club 42: 429-450). About 
500 plants of the various cultures were removed from the 
plots this past autumn, and space thus obtained especially
