Several generations of plants have been grown from cuttings 
and many data obtained regarding the variation exhibited 
by these plants. In some cases the conditions suggest a 
chimera relationship of different tissues. The results 
warrant a more intensive study of these forms with an 
investigation of the results of sexual reproduction. 
ome progress can be reported in the assembling and 
observation of plant chimeras. Two Bizzaria plants have 
been obtained from Florence, Italy, and it is planned to 
secure specimens of Cytisus Adami and the various Crataego- 
mespilus chimeras. The interesting case of reversal of 
tissue relations has appeared in a plant of Pelargonium 
zonale. For the experimental production of chimeras pre- 
liminary grafts have been made between various forms of 
Eranthemum, which seems favorable for this kind of investi- 
gation. 
It is my plan to supplement the experimental studies with 
such cytological studies as are desirable. To this en 
material has been fixed and imbedded for a study of the 
typical and the atypical nuclear divisions and of fertilization 
in Cichorium Intybus. It has also seemed highly desirable 
that the wealth of material afforded by the large collection 
of Cacti assembled in the greenhouses be utilized for various 
cytological research. Considerable material collected from 
a number of species has been properly prepared for future 
study and some microscopic preparations have been made 
from the material. 
The Experimental Garden and Greenhouse 
An area of ground adjacent to the propagating houses was 
utilized at your direction as an experimental garden. Here 
were grown various plants used in the experimental work. 
Coleus Blumet, Cichorium Intybus, Verbascum Blattaria and 
Hibiscus (various species) were grown for my personal study. 
Several forms of Mirabilis and a number of cereals were 
grown for student research, and several varieties of corn 
were grown for study by Professor R. A. Harper. Various
