transparent, thin and without the least indication of pollen. 

 The styles protrude 8 — 10 mm and are on the whole 15 — 

 16 mm long. 



Lange indicates the female plant as f. micropetala. 



Gynomonoecism: A few $ together with ^. 



Norway, Sweden: Gynodioecism. I found $ in Øster- 

 dalen and on Dovre, as also in the neighbourhood of Stock- 

 holm; it may have very rudimentary stamens, and the dia- 

 meter of the corolla may be 17 — 18 mm, consequently much 

 larger than recorded above. ^ protandrous. Both zygo- 

 morphic. Trioecism with g and ? > cJ according to Axell. 



26. Silène maritima With, 



Norway (Altenfjord). 5: Rather markedly protandrous 

 with the usual development in three sets, but the cor.-st. 

 may spread out singly and almost simultaneously with the 

 cal. -St. Calyx 15 — 16 mm in length; diameter of corolla 13 — 

 15 mm, corolla-tube about 13 mm, stamens 14 mm in length, 

 protruding beyond the throat. As the styles ultimately come 

 into contact with the anthers, and the latter may still con- 

 tain pollen, self-polHnation may take place. The scales at 

 the throat consist of such low protuberances as to be almost 

 wanting. At night the flower stood fully expanded, white 

 and fragrant. After rain there was much water in the base 

 of the flowers, even among the basal portions of the stamens. 



Iceland (Reykjavik; 4.8.1886, A.Feddersen). Rela- 

 tive size of parts about as those given above, but the dia- 

 meter of the corolla 18 mm. Decided protandry. Ultimately 

 the styles protrude 6 — 7 mm. Various flies and plant-lice 

 were found between the calyx and the corolla. 



27. Silène rupestris L. 

 Norway (Romsdalen, Dovre). ?: Protandrous in three 

 sets, rather markedly. Calyx about 4 — 5 mm, petals 4^/3 mm,
