Lindman (on the Dovre), 13 mm.; Ekstam, 12 — 20 mm.; Müller 

 (in the Alps), 22 mm. 



The stamens are spreading and parallel with the corolla; 

 they are entirely glabrous and the pores at the apex of their 

 two short anther-tubes (Fig. 44 C) turn outwards, away from 

 the stigma, the five rays of which are large and erect and 

 stand opposite to the diaphragms of the ovary (Fig. 44 C). 



The stamens generally occur in groups of 2 and 3;

A, Stamen. B, Pistil. G, An abnormal flower (fully ^/i; 14 mm. in diameter): 6-merous 



calyx; 6-merous corolla; 10 stamens; 5-cleft stigma; the antisepalous stamens have the 



larger anthers. D, Stamen. E, Pollen tetrads. (E. W.) 



Linné has, according to Lindmân, given a diagram of this in his 

 "Ölandska Resan." 



Fig. 44 С shews one of the frequent deviations from the 

 normal type with 6-merous calyx and corolla (see Malme, I.e.). 



In Finland Poppids found it to be but rarely visited by 

 insects (the pollen-seeking Aricia meteorica L.). 



After having set fruit, the shoot dies away entirely, if not 

 during the same year, then in one of the following years. The 

 plant appears never to develop lateral shoots.
