Project 5. Cytology of Sports of Nephrolepis 
Scope: 
1. Nuclear differences corresponding to the wide external dif- 
ferences among these mutations. The determination of possible 
chromosome differences existing among the species and the two 
groups of variations is a problem of very great interest. 
Status: 
Work has not yet been initiated, but plans are being matured. 
Project 6. Conservation of Native Plants 
Scope: 
The consideration and trial of practical and experimental 
methods in conservation of rare native plants. 
e problem of conservation of native plants comprises two 
quite different phases: first, the study of the situation and of what 
plants require conservation; second, the matter of practical meth- 
ods of preventing the extinction of rare plants. This latter prob- 
lem is extensively carried on by campaigns for education and the 
enacting of “game laws” for plants. The problem calls for con- 
sideration of experimental propagation and distribution of rare 
forms, and this phase touches upon matters of plant distribution. 
Status: 
In the popular phases of plant conservation a considerable num- 
ber of articles analyzing the problem have been written and given 
wide distribution. Reprinting various state laws, helping in 
the preparation of the law for New York State (enacted April 
13, 1926), lectures from the scientific standpoint, propagation and 
distribution of the Hart’s Tongue fern (Scolopendrium vulgare) 
for naturalization purposes have been undertaken as an experi- 
mental demonstration of one fundamental method of conservation.
