54 CARL SKOTTSBERG, A BOTANICAL SURVKY OF THE FALKLAND ISLA^'I)S. 



scarce. E. F., common round Port Louis! Port Stanley! Port Harriet! Arrow 

 Harbour ! W. F., Port Howard! and probably many other places. — Chile, Prov. 

 of Maule to Fuegia, Staten I. 



Erigeroii L. 



49. E. ineertus (d'Urv.) Skottsb. (Hieracium? incertum d'Urv. E. Siillivani 

 HooK. fil., E. alpinus L. var. myosotifolius Hook. fil. ex VVright.) 



Althougli the S. American species of Erigeron are far from well known, I have 

 not the slightest doubt as to the nature of d'Urville's Hieracium? incertum: it is 

 the Falkland species of Erigeron, and the description is very characteristic. Hooker 

 called it E. Sullivani; his diagnosis is, however, not so good as d'Urville's, provided 

 that the species is the same, which Hooker himself seems to have been sure of. The 

 oldest specific name is incertum, thus E. incertus (d'Urv.). Mrs. Vallentin's beautiful 

 and typical specimens of this plant were called E. al^pinus L. var. myosotifolius 

 Hook. fil. ; this is evidently an errour, for Hooker's variety, according to Reiche, 

 Fl. de Chile {--=E. myosotis Pers. {7ion Remy!)) is really nearly related to E. alpinus, 

 which is impossible to say of E. Sullivani; this species has been omitted by Wright. 

 I have reasons to believe, that it has not been found in South America, though 

 quoted by some authors. 



Dry places in the heath, rare. E. F., Tyssen Islands (Cunningham ex Wright); 

 W. F., Roy Cove (Mrs. Vallentin 90!, Nichol ex Wright), Spring Point! — 

 Endemic. 



Chiliotrichum Cass. 



93. Ch. diffusuin (FoRST.) Reiche. (Amellus diffusus Först., Ch. amelloideum 

 Cass.) 



Abundant in W. and E. F., but needing shelter to be well developed, then 

 often forming a brushwood of man's height; so in depressions between the hills 

 near Port Albemarle, where I have seen by far the most luxuriant growth of this 

 plant. The brooks are often lined with a greyish green börder of Chiliotrichum. — 

 Chile from 45° to Cape Horn, S. Patagonia, Staten I. 



Bacclmris L. 



89. B. inagellauica Pers. 



I have always regarded this species as zoogamic, but af ter my studies in the 

 Falklands I am inclined to believe, that the wind ma}'^ also act as a fertihzing agent. 

 It is dioecious, and the flower-heads are not very conspicuous, with colours like those 

 of Gnaphaliiim sjncatum Lam. and without scent or honey. In the male heads, the 

 sterile pistillum sweeps out the pollen; it is exposed on the surface of the pappus, 

 which does not prevent it from being carried off by the wind, while in the female
