Smithsonian Report, 1963. — Shetler 



PUATE 5 



1. The very early purple saxifrage (Saxifraga oppositifolia), an extremely wide-ranging 

 arctic-alpine species. Observe the highly telescoped stems and consequently much- 

 compacted leaves. Plants slightly larger than natural size. Photograph by James 

 Warren. 





2. A common dwarf arctic willow, Sali.x phlebophylla, wliich pixijccts onl\^ a few inches above 

 the ground and tends to form large mats. Here the mature catkins, scarcely larger than 

 a man's thumb, can be seen beginning to shed their cotton-tufted seeds (Eagle Summit, 

 late June 1957; see pi. 4, fig. 2). Notice the scalloped leaves of Dryas octopetala in the 

 background.
