40 CARL SKOTTSBERG, A BOTANICAL SURVEY OF THE FALKLAND ISLANDS. 



Callitrichaceae. 

 C.illitriclie L. 



56. C. aiitarctica Engelm. (C. verna d'Urv. a. o., p terrestris Hook. fil.) 

 In ponds and streams; also on damp soil. E. F., Port Louis! Port Stanley! 

 Sparrow Cove! Low Bay ! W. F., Westpoint Island! Beaver Island! (on humid soil, 

 t", terrestris). — Fuegia, Staten I,, South Georgia, Prince Edward I., Kerguelen 

 and Heard I., New Zealand and islands south of it. 



Empetracese. 



Empetrum L. 



5. E. rubriim Vahl. (E. nigrum L, var. rubrum A. DC.) 



I do not know why Mr. C. H. Wright has again reduced this to a variety of 

 E. nigrum; I think that tlie reasons for keeping them apart are as good as before 

 (see Fl. ant., p. 345). 



Nearly always dioecious. cT: sepals påle green with crimson tips; petals crimson, 

 paler at the base, filaments deep crimson, anthers dark violet. ? : sepals yellow, 

 petals darker than in d", ovary dull green, stigma dark purple (»atrorubens»). Colours 

 brigliter than in E. nigrum. 



One of the commonest plants, abundant in the heath, from the sea level to 

 the summits of the mountains. — Patagonia, Fuegia, Staten I., Tristan d'Acunha. 



Violaceae. 

 Viola TouRN. 



27. v. iiiJiculata C A V. 



Cleistogamic flowers and fruits were seen in November. — Fairl}^ common, 

 especially on overhanging banks near the sea, E. F., Port Louis! Port Stanley! 

 W. F., Port Philomel, Halfway Cove! Rabbit Island! Beaver Island! — Fuegia, 

 S. Patagonia. There has been a great deal of confusion about South American 

 violets; the true V. niaculata Cav. probably does not occur so far north as was 

 supposed. 



233. V. trideiitata Menz. 



An alpine species, only in the Falklands descending to near the level of the 

 sea; very scarce. »On the mountains, 1,200 — 1,500 feet», Hooker. E. F., A moun-
