in the axil of the uppermost leaf of the rosette; or, in case an 

 inflorescence is developed in this, then in the axil of the leaf 

 which is the next below (see Fig. 31 Л, B)] its leaves expand 

 even during the flowering-period of the parent shoot. A few 

 other shoots, usually 1 — 2, are developed in basipetal succession 

 from the axils of the two next lower leaves of the rosette. 



On older rhizomes, according to Lindmark, small buds occur 

 which do not develop. All the branches begin with foliage- 

 leaves, but when the plant grows in moss these become small 

 and less perfect (Fig. 31 ^ at s). Small runners may occur 

 (Fig. 31 Б); they bear very small, entire leaves, and appear to 



be developed only under certain condi- 

 tions, viz. in deep damp moss. The 

 time for their flowering depends on the 

 prevailing conditions (Lindmark). 



The germination of the seed, 

 and the seedlings have been de- 

 scribed and figured by Lindmark. Dur- 

 ing the year in which germination 

 takes place a leafy shoot with rather 

 short internodes is developed which, 

 like all the other shoots, passes the 

 winter with its buds open. The seeds 

 do not germinate until the year after they ripen. 



The inflorescence is terminal on a long leafless pe- 

 duncle. The uppermost lateral shoot sometimes flowers simul- 

 taneously with the parent shoot, and with or without a rosette 

 of foliage-leaves (Fig. 31 A). In unfavourable localities the in- 

 florescence remains sessile among the leaves of the rosette 

 (f. acaidis; Fig. 31 i^, Fig. 32). 



Saxifraga stellaris f. comosa Retz. In the regions of the 

 extreme north, a form comosa occurs, upon which only the 

 terminal flower, or at most only a few normal flowers, are fully 

 developed, and instead of flowers bulbils occur, far more abun-
