 Syn. C. billardieri Fenzl.; C. quitensis Bartl. 



Also in Central, Western and Northwestern Patagonia. 



P- 39 *> 39 2 : Skottsberg regards Colobanthus saginoides Bartl. as 

 probably a synonym of C. crassifolius Hook. f. (p. 392), also of C. bil- 

 lardieri Fenzl. (p. 391) ; C. crassifolitis being thus polymorphous. 



C. lycopodioides Gris. and C. lechleri Phil, are, according to C. Reiche, 

 Flor. Chil., Ill, p. 388, identical with C. sttbulatus (d'Urv.) Hook. fil. 

 Also C. polycnemoides Hieron. is synonymous with the last-mentioned 

 species. 



C. subulatus (d'Urv.) Hook. f. is found also in South Georgia Id., Falk- 

 lands, South Isle of New Zealand, Campbell's Isle, and Victoria, every- 

 where making dense masses (Skottsberg). 



Colobanthus crassifolius (d'Urv.) f. Hook, is also in South Georgia Is.

A. patagonica Phil, is placed by Reiche as a variety of the Chilian 

 species Arenaria palustris Naud., whilst Macloskie retains it as a distinct 

 species. Spegazzini, on the other hand, subordinates both A. pahistris 

 and A. patagonica under Arenaria sevens H.B.K. (described in p. 394). 

 Arenaria andicola Gill, is placed by Rendle and Spegazzini as a variety 

 of A. sevens, whilst Reiche and Macloskie place it as a variety of Aren- 

 aria serpylloides Naud. The last species is given both by Reiche and 

 Macloskie the rank of an independent species ; Spegazzini places it as a
