Herb. Upsala, which was forwarded as L. apetala L. var,, 

 but according to Тн. Fries is a true Mel. affine). 



Norway (Altenfjord, about 70° N. lat.). 5, ?. Protogyny. 



^: The anthers of the cal.-st. in my Fig. 43,'Б are open 

 and pressed against the styles to which they adhere by 

 means of the pollen tubes. The styles (4 — 5 — 6) are slenderer 

 than in $; the cor.-anth. Ьал^е not yet dehisced. 



In another ^ all the anthers were of equal height and 

 at a level with the upper one-third of the styles, consequently 

 they were all like the cal.-anth. in my Fig. 43, B. The stig- 

 matic papillae extend down to the base. 



$ (Fig. 43, i), £'): The petals are narrow, smaller and 

 less notched at the apex, and the scales at the throat are 

 absent, the stamens sterile, either with anthers (pale, trans- 

 parent) or even entirely without anthers, but terminating 

 in long hairs. Styles 4, thick, twisted. The stigmatic papillæ 

 are short, and fairly equal in length from base to apex. The 

 ovary is considerably larger (both longer and thicker) in $ 

 than in § (Fig. E and B). 



Spitzbergen (15. 7. 1882; Nathorst). ^: Protogyny. 

 In a well-developed bud the styles were spread out and the 

 stigmas almost ripe, and the anthers had so far developed 

 that the pollen-grains were lying isolated. In older flowers 

 the stigmas were found covered with germinating pollen 

 before the cor.-st. had elongated and opened their anthers; 

 this pollen comes evidently from the cal. -anthers. Fruit 

 ripens in September; also in Nova Zembla. 



25. Silène inflata (Sahsb.) Sm. 

 Flower scentless; moth-pollinated. The petals are not 

 involute^). 



Vaucher has a great many good biological observations on the 

 Sileneæ which have not been noticed in the newer literature, for
