it has increased and the diameter is now about 9 mm. The plant 

 is decidedly homogamous, and for a long period. Spontaneous 

 self-polh nation occurs by the anthers touching the stigma. The 

 pollen is pale minium-red. Tiie disk is greenish and shiny. 



Saxifraga stellaris L. — Fl. p. 79. — (Trangisvaag, July; Vest- 

 manhavn and Lervik, Aug.). The diameter of the flower is 11 — 15 

 mm. The white, npward-curving petals have two large orange-co- 

 loured spots above their bases. Slight protandry. Much honey is 

 secreted and the plant sets fruit abundantly, from almost every flower. 



Scilla verna Huds. — Fl. p. 93. — (Trangisvaag, July 18). The 

 flowers are pale-purple. Their diameter is from 12 to 14 mm. The 

 perianth-leaves spread somewhat in a starlike manner, but during 

 the final stages of flowering they bend upwards. The stamens, 

 which are erect or slightly spreading, turn the slits of their anthers 

 slightly upwards. The plant is homogamous. The anthers are 

 always somewhat remote from the styles which are in the middle 

 of the flower and are bent backwards. Spontaneous self-pollination 

 appears to be able to take place only with great difliculty. Insects 

 doubtless visit the flower in search of the honey which is seen in 

 large drops between the ovary and the stamens. The piants set fruit. 



Sedum Rhodiola D. C. — Fl. p. 65. — (Trangisvaag). Ripe fruit 

 is produced, and is set as early as July. 



Sedum villosum L. — Fl. p. 66. — (Trangisvaag). The flower 

 is about 7 — 8 mm. in diameter. The petals are pale rose-red with 

 yellow bases; they darken with age. Yellow honey-glands occur 

 outside the pistils. The flower is protandrous; the antisepalous 

 stamens are the first to develop and they bend inwards towards 

 the middle of the flower; there the anthers shed much pollen, 

 where the stigmas are to be found which have ripened before 

 the antipetalous stamens bent inwards. Spontaneous self-pollination 

 is not only possible, but almost inevitable, if insect-pollination does 

 not occur early; sometimes the anthers are found in direct contact 

 with the stigma. 



Sibbaldia procumbens L. — Fl. p. 78. — Ripe fruit is formed. 



Silene acaulis L. — Fl. p. 64. — (Trangisvaag, July). The pis- 

 tillate flowers are very small, measuring 6 — 7 mm. across; the 

 staminate flowers are 11 — 12 mm. in diameter, and a rudimentary 

 pistil occurs at their base. The pistillate flowers are deeper red 

 than are the staminate.
