Caryophyllaceæ. 291 



are usually somewhat club-shaped, becoming broader at 

 the apex, or even 2-lobed (Fig. 27 C\ e 3 ). According to 

 Lindman the flower has a sweet perfume (Dovre), in Green- 

 land I made the note "White, scentless." 



A remarkably small-flowered form was gathered by 

 P. Eberlin in East Greenland (Kutek; 5. 8. 1884); it is 

 figured in Fig. 27, E. The petals are in their last stage only 

 6 mm long and of the same length as the calyx. 



? occur, but rarely, as far as I can see. I have seen 

 specimens from East Greenland, the stamens of which are 

 shown in Fig. Z), but as some of the stamens appeared to 

 be normal, these flowers were consequently perhaps not 

 purely ?. 



Gynomonoecism: In the same tuft I found g and ? 

 with large rudiments of stamens. 



Fruit is set in Greenland, for instance at 67° — 70° N. 

 lat. A $ was found pollinated, so that insects must certainly 

 be of assistance there. 



Norway. Gynodioecism (Tromsö, 21. 7. 1885); £ ho- 

 mogamous (West Finmark; Dovre; Tronfjaeld); in all its 

 parts as in Greenland. — $ has sometimes clear, transparent 

 anthers, devoid of pollen, sometimes less decidedly reduced, 

 and the same plant may show diversity of floral condition 

 (Fig. 27, F). — Lindman : Homogamy, regular self-pollination. 



I found transitional forms from $ to $ near Hammers- 

 fest, for instance, three rudimentary cal. -st., the rest nor- 

 mal; but I found cal. -st. < cor.-st. in a flower which occur- 

 red on a plant which had otherwise entirely ? flowers. In $ 

 flowers I have most frequently found the cal.-st. to be the 

 shortest. £ also occurred in which the stamens were so short 

 that the backwardly-bent styles were not in contact with 

 them, and in several £ the cal.-st. were < cor.-st.; but the 

 contrarv is the rule.
