Caryophyllaceæ. 307 



Spitzbergen (17.7.1882; Nathorst). Fig. 33, A. Ç: 

 Appear to be protandrous. Do not differ essentially from 

 the Norwegian specimens as regards size, and appear to 

 agree exactly with them in other respects. Malmgren records 

 that the Spitzbergen specimens have larger flowers than 

 those found in Russian Lapmark. ("Öfver. af K. Vet. Ak. 

 Förh.", 1862). 



15. Moehringia lateriflora (L.) Fenzl. 



East Finmark. Appears protandrous or homogamous. 

 Ultimately both the stamens and the styles spread out. 

 The styles are hairy along their lower half. 



16. Minuartia groeiilaudica (Retz.) Fenzl. (Fig. 34.) 



Styles 3, 4. 



West and East Greenland. £: Slight protandry, 

 begins no doubt often with homogamy. In large buds I found 

 the anthers of the erect stamens partially open and closely 

 surrounding the erect, spreading styles, whose stigmas were 

 not yet quite ripe (Fig. 34, D). But I have also observed 

 the same position in expanded flowers, and then self-polli- 

 nation is almost inevitable (Fig. E). The stamens and styles 

 may be somewhat more outspread as shown in Fig. F, which 

 is evidently connected with conditions of weather. The thin, 

 white petals are 7 — 9 mm long and 5 mm wide, about twice 

 the length of the sepals, which are 4 mm (Fig. A, B, C). 

 Diameter 10 — 13 mm. 



I found the seeds to be sometimes finely warted (Fig. G, 

 from Ilua) and sometimes finely wrinkled (Fig. //, from 

 Dronning Louise's Island). I am not prepared to say the 

 reason of this difference, which is however but slight.
