Linpman (on the Dovre), 13 mm.; Exstam, 12—20 mm.; Miter 
(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. €, An abnormal flower (fully 3/1; 14 mm. in diameter): 6-merous 
calyx; 6-merous corolla; 10 stamens; 5-cleft stigma; the antisepalous stamens have the 
larger anthers. D, Stamen. Z, Pollen tetrads. (E. W.) 3 
Linne has, according to Linnmån, given a diagram of this in his 
“Ölandska Resan.” 
Fig. 44 C shews one of the frequent deviations from the 
normal type with 6-merous calyx and corolla (see Marne, l. c.). 
In Finland Porrws 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.
