Measurements of two plants of each accession 
were averaged for each character. 
Periodic observations were made of flower- 
ing times (anthesis) in the Palmer garden. 
Flowering material was examined at the end of 
the season for the production of seed, but no 
quantitative measure was obtained of seed pro- 
duction. 
An effort to obtain root weights was pre- 
vented by the nature of the mica peat growing 
medium. It was impossible to separate the mica 
peat from the mass of root material developed in 
the second season by the perennial plants with- 
out losing an unknown but significant quantity 
of root material in the washing process. 
Following are the origins, elevations, and 
habitat information for the transplant entries. 
Locations of the collection sites for the. Alaskan

Results 
Flowering culm production was highly vari- 
able among both the arctic and boreal entries 
within species. Most of the arctic entries increas- 
ed in flowering culm production at both gardens 
in the second and third growing seasons. Many 
of the boreal entries declined in number of 
flowering culms at Palmer in the third season, 
particularly if they had produced a large number 
in the preceding season. Most of the boreal 
entries succeeded in flowering at Prudhoe, but 
many produced very few culms. A few were
