28 CARL SKOTTSBERG, A BOTAKICAL SURVEY OF THE FALKLAND ISLANDS. 



SperguLaria Presl. 



53. S. media (L.) Presl. (Arenaria media L. in Fl. ant.) 



The Falkland plant is small, glabrous, and few-flowered. On sea-shores, rare. 

 E. F., San Salvador Bay (Hooker), North Arm! W. F., New Island! Westpoint 

 Island I — Widely spread in N. and S. temperate regions, also in S. America. 



Colobaiithiis Fenzl. 



103. €. crassifolius (d'Urv.) Hook. fil. (Sagina crassifolia d'Urv.) 

 Nearly confined to the vicinity of tlie sea, on rocks, shingles or sand, fairly 

 common. E. F., Port Louis! Port Stanley! Sparrow Cove! Arrow Harbour in the 

 meadows, abundant! W. F., Port Howard! Spring Point! Port Philomel, Halfway 

 Cove! Rabbit Island, forming extensive cushions in the dead tussock-association ! — 

 W. Patagonia — Fuegia, Staten I., South Georgia, Graham Land. 



11. C. subulatus (d'Urv.) Hook. fil. (Sagina crassifolia d'Urv.) 

 Of all Falkland plants with entomogamous flowers, this has, I believe, the 

 least conspicuous ones (Plate II). They are not raised above the foliage (fig. 5), 

 their colour is green and they hardly open to show the white anthers, and 

 stigmas (fig, 6); in both form and colour the leaves of the perianth (2+2!) are like 

 the common leaf. There are yellowish-green nectaria between the stamens (fig. 7). 

 The flowers are homogamous, and as the anthers stånd on a level with the stigmse, 

 selfpollination is, as a rule, effected. — 



A characteristic plant of the rocky shore, on steep cliffs of ten filling up the 

 crevices with its densely packed, härd cushions. Also in the alpine heatli on the 

 top of Mount Maria! — Fuegia, Staten I., South Georgia, Victoria, New Zealand, 

 Campbell I. 



Ranunculaceae. 

 Caltlia L. 



3. C. appendiculata Pers. 



The expanded flower measures ± 10 mm., but is not raised above the foliage 

 and not very conspicuous, on account of the dull yellow colour of the perianth. I 

 do not remember to have seen female individuals. The filaments are greenish white, 

 the anthers påle yellow. The ovaria are dull green with yellow stigmse. Both sexes 

 have been described by Hooker in Fl. ant. p. 228. It is possible, that the basis of 

 the perianth produces lioney. 



As far as I know, this species has only been collected in the easfc part of E. F., 

 but it is easily overlooked. I found it in some places round Port Louis and Port 

 Stanley, where it seems to occur in many of the peat-bogs, often consociated witli
