6. Stellaria longipes Goldie {St. Edwardsii R. Br.) Fig. 28. 



Greenland. Gynodioecism; "i > $. Slightly protandrous 

 or homogamous flowers. 



$ appear to be more or less decidedly protandrous or 

 decidedly homogamous. The specimen figured in Fig. 28, A 

 had all its anthers open, but the stigmas were still unripe. 

 In the fully developed flower the stamens stand at a distance 

 from the pistil, so that the anthers are not in contact with 

 the stigmas which are never markedly revolute. The flower 

 secretes honey abundantly. I am not prepared to say whether 

 self-pollination takes place regularly, but judging from the 

 position of the parts of the flower, there does not appear 

 to be anything to prevent this, and the anthers are not 

 empty when the stigmas ripen. The stigmatic papillæ extend 

 half the distance down the styles (Fig. 285). The number of 

 the styles varies, being sometimes as many as four. 



$ occur as far north as Upernivik (about 73° N. lat.j, 

 according to material gathered by C. Ryder (3. 9. 1886). 

 They are much smaller than 5 (compare Fig. 28, D and E 

 with A, or, for instance, the petals d 1 , e 1 with a 1 ); while £ 

 is as much as 13 — 14 mm in diameter, 9 is only 7 — 10 mm; 

 the petals of £ are 7 — 7 x / 2 mm, of $ 5 — 6 mm. But other- 

 wise the $ flowers vary as regards the relative size of the 

 parts. Specimens occur in which the petals are longer than 

 the calyx, others in which they are of equal length. The 

 stamens (Fig. G) are smaller than, or at most of the same 

 size as the ovary (Fig. D). The pistil is so large in proportion 

 to the corolla that the apices of the styles protrude (Fig. 

 D, E). The stigmatic papillæ are longer in $ than in £ (Fig. F 

 and i 6 compared with B and c). I have no note of having 

 seen ripe fruit from Greenland.

 It is remarkable the small size which the flowers (some-
