lies loose in them. The stigina appears to be ripe at that time and 

 spontaneous self-pollination would have been possible if the pollen 

 had been dry enough to fall out, but this does not appear to be 

 the case. In a recently expanded flower with a still very narrow 

 throat, the stigma occupies the mouth and is able to retain the 

 pollen. In a somewhat more open flower, the stigma protrudes 

 farther, and the pollen can be seen scattered in the interior of 

 the corolla. The flower contains much honey. In a still further 

 expanded flower the viscid stigma protrudes about one mm. beyond 

 the throat towards the upper side of the flower. The stamens can 

 be seen further down. The flower appears, therefore, to be very 

 slightly protogynous. Some corollas are found which have been 

 bitten by insects. 



Euphrasia borealis (Towns.) Wettst. — Fl. p. 56. — (Trangisvaag, 

 July). Large-flowered. The upper lip is lilac in colour, with 4 — 6 

 darker, purple-coloured stripes ; the lower lip is whitish, with a 

 yellow spot and a few dark purpie stripes. Even in very young, 

 scarcely-expanded flowers, the style protrudes and carries the stigma 

 forward, well before the throat of the corolla. The anthers stand 

 behind the stigma. There is scarcely a distance of lV2mm. be- 

 tween the stigma and the underlip. Even in the bud the 

 pollen-grains lie loose in the anthers and may easily be removed. 

 In older, widely open flowers the anthers have separated from each 

 other and the style was found pushed to one side, perhaps by in- 

 sect-visitors ; these, however, have not been observed. The plant 

 sets fruit. 



Euphrasia scotica Wettst. ~ Fl. p. 56. — (Trangisvaag). Small- 

 flowered. Appears to resemble the preceding in all essential characters. 



Fragaria vesca L. The fruit ripens readily on Vaago. 



Galeopsis Tetrahit L. — Fl. p. 48. — (Trangisvaag, July). Flowers 

 rose-red with a glaring yellow and purple-coloured spot on lower 

 lip. They are homogamous; thej' vary somewhat in size. In the 

 smaller flowers the stigma is situated between the lower anthers, 

 and in the larger flowers it is on a level with the higher anthers 

 or even above them. 



Galium saxatiie L. — Fl. p. 51. — Protandrous, with the stamens 

 at first curved somewhat inwards, afterwards turned outwards. 

 Direct contact of anthers and stigma has not been observed. The 

 plant sets fruit abundantly.
