Table 2. Portion of a list of species occurring on the east coast of Greenland at 

 fourteen localities ranging from (A) 70° N latitude, southward to (N) 65° N latitude. 

 Both presence and degree of importance of the species in each locality is indicated 

 by the field-assigned numbers according to the following scale: 



5 — very common (important constituent of several closed communities); 4 — 



common (more scattered occurrence); 3 — here and there; 2 — uncommon; 1 — rare; 



-\ present. 



The listed species were selected to show how the system of values indicates range 

 limits and progressive changes of importance with latitude. From Bocher. 24 *
