in the main shoot, bud-scales, for the protection of the 

 winter-buds. In the adventitious shoots, also, no rosette of 

 fresh foliage-leaves occurs in the flowering year. 



I have been so fortunate as to have Arctic material at 

 my disposal, collected as late as on the 1st of September 

 (Danmarks 0, leg. Hartz); it contained both buds which 

 would flower next year, and also younger buds. The former 

 were of a considerable size (1.5 cm long, 1cm thick); ex-

ternally they were protected by the somewhat broadened 

 bases of the dead leaves of the rosette, then followed 10 — 12 

 arched, pointed bud-scales, 10 — 13 mm long, and 5 mm broad, 

 and hairy along their edges; the outermost of these bud- 

 scales were withered. The young foliar organs were already

 florescence were floral buds about 0.5 mm in size, all enveloped
