(terminal?) was found with normal stigmas, but with stamens 

 which were much shorter than usual, nine of which had no 

 pollen in their anthers, and were decidedly sterile, but in the 

 tenth there was a little pollen (Fig. 32 E). 



According to LiNDMARK, the seeds do not germinate until 

 the year after they have been formed, unless they are exposed 

 to hard frost.

А herb of the Primida-iyTpe. It has a short (one to a few 

 cm. long) rhizome, vertical or slightly oblique (Fig, 31 -4, ^, jF). 

 This dies away gradually at its lower end, so that vegetative 

 propagation takes place by the lateral shoots becoming indepen- 

 dent. The rhizome lives scarcely more than 2 — 3 years; the 

 adventitious roots are slender and numerous. The primary root 

 can live at least 2 years, and is found even on flowering speci- 

 mens (Lindmark). The length, branching, etc. of the rhizome 

 varies according to the diverse habitats (cf. Lindmark), 



The foliage-leaves are in a rosette, but are fairly erect 

 (Figs. 31, 32). Where the rhizome grows between moss, the
