bases of the stamens. The innennost anthers may shed pollen upon 

 the outermost stigmas. Appears to be homogamous, and is visiled 

 by flies. The fruit is of a fair size as earlyas July 25th. 



Ranunculus acer L. — Fl. p. 74. — (Sydero, July; Mygledal, 

 Aug.). The diameter of the flower appears to vary greatly; 

 in specimens from rocky flåts it measured 15 — 18 mm., in specimens 

 from the lowlands (Trangisvaag, Kvalbo, Lervik) as much as 3 cm. 

 Homogamy occurs. Spontaneous self-pollination must be difficult be- 

 cause the stamens are spreading; the outermost stigmas may, how- 

 ever, be dusted with pollen from the innermost, more erect stamens. 

 The plant sets fruit; it is visited frequently by several species of flies 

 (Hilara chorica, Aricia variabilis, Eristalis nemoriini, Anthomyia tri- 

 quetra, Homaloimjia spathiilata) . 



Ranunculus Flammuia L. — Fl. p. 74. — (Trangisvaag, Juh^). The 

 flower is 18 — 23 mm. in diameter. Homogamy or protandry oc- 

 curs. The outermost pistils thrust their stigmas between the inner 

 stamens, and spontaneous self-pollination can thus take place. Oc- 

 casionally the piants appeared to be protogynous. At Viderejde and 

 Mygledal it is seen fruiting abundantly in August. 



Ranunculus repens L. — Fl. p. 76. — (Trangisvaag, July 22). 

 Visited by Aricia variabilis and by another species of Diptera. 

 (Rhinanthus, vide Alectorolophus). 



Sagina ppocumbens L. — Fl. p. 63. — (Trangisvaag). Appears 

 to be somewhat protogynous. Spontaneous self-pollination takes 

 place. 5-merous flowers also occur. 



Sagina subulata (Sw.) Prsl. — Fl. p. 64. — (Trangisvaag, July). 

 Homogamous. Flowers very small (the diameter is about 4 mm.). 



Saxifraga hypnoides L. — Fl. p. 79. — (Trangisvaag). The flower 

 is from 11 to 17 mm. in diameter; when, as in rare instances, the 

 petals are spreading, the diameter is as much 22 mm. The petals 

 are erect and divergent, and yellowish-green in colour. Highly pro- 

 tandrous; antisepalous stamens ripen before the antipetalous, but 

 the stigmas may ripen before the antipetalous petals have completed 

 their development. Honey is secreted abundantly. Spontaneous 

 self-pollination may occur. The llowers are visited by Aricia varia- 

 bilis and Atractodes vestalis. 



Saxifraga nivalis L. — Fl. p. 79. — (Trangisvaag). The young 

 flower is about 6 — 7 mm. in diameter, but in the pistillate stage
