stand around the stigma, and lipen a short time before it. Homo- 

 gamy aiso occurs. Spontaneous self-pollination takes place. 



Cakile maritima Scop. var. latifolia (Poir.). — FI. p. 66. — (Kvalbo, 

 July). Has a delicious perfume, which recalls that of vanilla. The 

 anthers of the longer stamens turn laterally towards the shorter 

 stamens at an early stage; they are all above the stigma. Spon- 

 taneous self-pollination may easily take place. Usually all the 

 flowers set fruit. 



Caltha palustpjs L. — Fl. p. 74. — (Frodebo on Sydero, July 19). 

 The flower is 32—40 mm. in diameter. Drops of honey may be 

 seen upon the bases of the ovaries. The flowers are visited by 

 flies. At Trangisvaag, Mykledal and Kvannesund (Aug. 5) the spe- 

 cimens were usually found fruiting. 



Cardamine pratensis L. — Fl. p. 66. — (Trangisvaag, July). The 

 flower reaches a diameter of 21 mm. It is homogamous. The 

 anthers of the longer stamens are above or on the same level as 

 the stigma; they turn very decidedly towards the shorter stamens, 

 so that it would appear to be difficult for their pollen to be Irans- 

 ferred to the stigma. The anthers of the shorter are situated below 

 the stigma, or their upper ends may stand on a level with the 

 latter, in which case contact with the latter transfers pollen to it. 



Cardamine hirsuta L. — Fl. p. 66. — (Trangisvaag, July). Spon- 

 taneous self-pollination is inevitable, and every flower sets fruit. 

 The stigma protrudes from the bud. In recently expanded flowers, 

 of which the petals are still fairly erect, the longer stamens are 

 bent inw^ards and the anthers, which are open, are standing above 

 the ripe stigma; the anthers of the shorter stamens are not yet 

 open. Later on, the shorter stamens grow up and the stigma is 

 carried up among the anthers of the longer stamens. 



Cerastium Edmondstonii (Wats.) Murb. et Ostenf. — Fl. p. 60. — 

 (Trangisvaag, July; Fuglo, Aug.). Appears to be homogamous or 

 slightly protandrous. Spontaneous self-pollination occurs. The 

 flowers set ripe fruit. 



Cerastium vulgare Hartm. — Fl. p. 61. — (Trangisvaag, July). 

 Homogamy or slight protandry. The antisepalous stamens, while 

 the petals are as yet standing erect and the diameter of the flower 

 is only 4 mm., begin to bend inwards towards the middle of the 

 flower, and finally lie close to the stigmas, which even at that
