clearly evident in the height development of 
Alopecurus alpinus. The shortest forms in both 
gardens originated in the coastal tundra region 
followed by the Brooks Range entry, northern 
interior biotype, and Kenai Peninsula entry, in 
order of increasing heights. The Kenai Peninsula 
entry of this species resembled the Colorado 
entries more than the other Alaskan entries. The 
Colorado and southcentral Alaska entries grew 
tall, spread rather loosely from a dense central 
tuft at Palmer, and adapted poorly to the arctic 
site. The other Alaskan entries produced a more 
dense and shorter growing mat of material at 
Palmer and grew well at Prudhoe. The south- 
central coastal material of Alaska may be more 
closely related to the alpine forms of the Rocky 
Mountains than to the northern Alaskan 
material. 
No apparent conclusions can be drawn from 
the study regarding the possible significance of 
different ploidy levels within a species. In 
Deschampsia the diploid (2n = 26) appeared 
somewhat superior in both gardens to the 
tetraploid (2n = 52) collected from an alpine site 
on Caribou Mountain. However, the tetraploid 
race from Copper Center outperformed the 
diploid race from there in the arctic garden, 
whereas at Palmer the reverse was true. The
