flowered and blue-flowered plants, the latter both wild 
and cultivated, have been grown. The problems con- 
cerned with sterility have developed as an important phase 
of these investigations. Some statistical data were obtained 
regarding the variation in the numbers of flowers. The 
services of Mr. Gilman during his month of scholarship were 
an aid in these studies and throughout July and August 
Mr. Fraser assisted during the greater part of the forenoon 
in these studies. The studies of Cichorium will be pushed 
during the coming season as time and assistance will permit. 
With Verbascum Blattaria, first generations of inbred lines 
of white and yellow races and of crosses between them were 
grown. Relatively few of the plants bloomed this year. It 
is hoped that hereafter the use of cold frames during the 
months of March and April will enable us to force a majority 
of plants into bloom in one season. During the coming year, 
I trust, definite data will be obtained on the problems for 
the treatment of which this plant seems favorable. 
Progress can be reported in the studies of Hibiscus. 
Plants were grown from seed of types of H. Moscheutos, H. 
oculiroseus and H. militaris, and of various hybrid combina- 
tions. Wery few of these plants matured to the age of 
blooming. It is my plan to continue and somewhat extend 
these investigations. 
Observations on bud-variation in Coleus Blumei have been 
continued throughout the year. Several new types of color 
pattern have appeared. More intensive studies will be 
made of the frequency, character and stability of the varia- 
tions. Morphological and cytological studies of the various 
types were made by Mr. E. G. Arzberger on a scholarship 
grant for the month of June. His interest in the problem 
led him to devote another month to the studies. 
Some progress has been made in the breeding experiments 
with species of Carex. Preliminary experimentation has 
been made with several species not already mentioned to 
determine suitability for intensive study either by students 
or by myself
