NOTES ON SUBANTARCTIC FLORAS 133 



Enargea Banks et Sol. (3); E. polyphylla (Hook.) F. v. M. in south Chile and 

 western Patagonia, E. marginata (Gaertn.) B. & H. in Magellan and Falkland 

 Ids., and E. parviflora (Hook, f.) Skottsb. in New Zealand, generally considered 

 to be identical with E. marginata. I have found it necessary to reestablish 

 Hooker's Callixene parviflora: leaves with veins distinctly prominent on lower 

 surface, even the transverse ones, margins of leaves perfectly smooth, flowers 

 1-2 cm. across, with all parts smaller, berry whitish, whereas E. marginata proper 

 has obsolete veins, the transverse ones never being visible, the leaves have sca- 

 brous margins, the flowers are 2-3 cm. across, with larger stamens and style, and 

 the berry dark purple. 



Iridaceae. Libertia Spreng. (9) : 5 in Chile (1 extending to the Patagonian 

 channels at least), 3 in New Zealand (1 also in Tasmania and Australia), 1 in 

 Australia. L. elegans Poepp. (Chile) stands near L. ixioides Spreng. (New 

 Zealand). The latter is incorrectly credited to Chile. 



Fagaceae. Nothofagus Blume (17) is a striking example of bicentric distri- 

 bution. There are 6 species in New Zealand, 1 in Tasmania, 1 in Tasmania and 

 Victoria, 1 in New South Wales, 8 in Chile (some extending to the Argentine 

 slopes of the Andes, 3 extending to Fuegia). The evergreen section is repre- 

 sented by 6 species in New Zealand (the whole number found there), by 1 in Tas- 

 mania and Victoria, 1 in New South Wales, and 3 in Chile; the deciduous-leaved 

 by 1 in Tasmania and 5 in Chile. 



Proteaceae. Lomatia R. Br. (9) : 2 in Tasmania, 4 in eastern Australia, 



3 in Chile (1 extending to the Patagonian channels). Embothrium Forst. (5): 



4 in South America (1 extending south to Fuegia), 1 in eastern Australia. Orites 

 R. Br. (8) : 4 in Tasmania, 1 in Victoria, 1 in New South Wales, 1 in Queensland, 

 and 1 in the Chilean Andes. 



Loranthaceae. Phrygilanthus Eichl. (25-30) : two-thirds of the species in 

 South America from Mexico to southern Chile, 4 in Australia, 2 in New Zealand. 



Polygonaceae. Muhlenbeckia Meissn. (21) : 3 in New Zealand, 1 in New 

 Zealand, Tasmania and Australia, 6 in Australia, 1 in the Solomon Ids., 10 in 

 South America (Mexico to Chile). 



Caryophyllaceae. Colobanthus Bartl. (19-20), a difficult genus, where a 

 revision seems necessary. There are 9 species in New Zealand and the Sub- 

 antarctic Ids. (1 of these also found in Victoria, 2 also in South America), 8 addi- 

 tional species occur in the Andes from Ecuador to Fuegia, Falkland Ids., and 

 South Georgia, 1 in Kerguelen Id., 1 in New Amsterdam Id., 1 in Tasmania and 

 Victoria. The two species common to the New Zealand region and South America 

 are C. quitensis Bartl. and C. crassijolius (D'Urv.) Hook. f. (= C. Billardieri 

 Fenzl p. p.). C. Billardieri from Tasmania and Victoria (Spergula apetala Lab.) 

 seems distinct, C. apetalus (Lab.). C. subulatus (D'Urv.) Hook. f. (= C. Ben- 

 thamianns Fenzl) of New Zealand and Campbell Id., also reported from Vic- 

 toria, differs from true subulatus (Fuegia, Falkland Ids., South Georgia) in being 

 pentamerous ; it is probably a different species. 



Ranuncdlaceae. Caltha L. sect. Psychrophila includes 6 species: 2 in New 

 Zealand, 1 in Tasmania and Australia, 3 in the Chilean Andes and Fuegia (2 in 

 the Falkland Ids.). The species from New Zealand and Australia stand near the 

 American C. sagittata Cav. Myosurus aristatus Benth. is reported from Cali- 

 fornia, Chile, Patagonia, Fuegia and New Zealand. Ranunculus acaulis Banks
