NOTES ON SUB ANTARCTIC FLORAS 131 



the problem remains the same, and Cardot seems to have treated 

 his subject in a very able manner. 



The botanical museums in Sweden possess large collections from 

 nearly all subantarctic lands as well as from New Zealand and the 

 antarctic regions. Thus, in many cases it has been possible to 

 make the necessary comparisons between specimens from different 

 places. Through the kindness of one of the foremost botanists 

 in New Zealand, Dr. L. Cockayne, I received a number of plants 

 from that region representing species reported to be identical 

 with South American ones. I take advantage of this occasion 

 to thank him most heartily for his assistance. 



In the following paragraphs the figures given in parentheses 

 after the generic names indicate the number of species actually 

 known. I have done my best to get these as exact as possible, 

 but this is not easy. The orders follow according to Engler's 

 Syllabus. 



Taxaceae. Dacrydium Sol. (16) : 7 belong to New Zealand, 1 to Tasmania, 

 4 to New Caledonia, 3 to south-eastern Australia, and 1, D. Fonckii (Phil.) Benth., 

 to south Chile (extending to 52° 30'), apparently related to D. laxifolium Hook, 

 f. in New Zealand. 



Pinaceae. Araucaria L. (12; Australia, New Caledonia, Norfolk Id., New 

 Guinea, 3 in South America) of the section Colymbea: 1 in Australia, 1 in Brazil, 

 1 in Chile (also 1 extinct, from southern Patagonia). 



Cupressaceae. Libocedrus Endl. (8; 2 in New Zealand, 1 in New Caledonia, 

 1 in New Guinea, 1 in eastern Asia, 2 in Chile, 1 in California) L. chilensis Endl 

 and L. tetragona (Lam.) Endl. in Chile, the latter extending to Fuegia, corre- 

 spond to L. Doniana Endl. and L. Bidwillii Hook. f. in New Zealand. One species, 

 probably L. chilensis, is fossil in Falkland Ids. Fitzroya Hook, f . 2, 1 in Chile 

 between 39° and 43° S., the other (formerly regarded as the type of a separate 

 genus, Diselma) in Tasmania. 



Gramineae. Agrostis magellanica Lam. is found in southern Chile, Fuegia, 

 Falkland Ids., Kerguelen, Marion. Id., Heard Id., New Zealand, and the Sub- 

 antarctic Ids. Poa foliosa Hook, f . (Subantarctic Ids. of New Zealand) corre- 

 sponds to P. flabellata Hook. f. (Fuegia, Falkland Ids., South Georgia). Koe- 

 leria, Sect. Dorsoaristatae (13) has 3 in New Zealand, 2 in eastern Australia and 

 Tasmania, 2 in Asia, and 6 in Argentine and Patagonia (1 extending to Falk- 

 land Ids.). Domin thinks that the section is of South American origin, having 

 wandered to New Zealand; however, when indicating the route used he puts it 

 westward from Patagonia, the direction opposite to that generally accepted 

 on account of the Antarctic Drift. Hierochloa redolens R. Br. (Victoria, Tas- 

 mania, New Zealand, Subantarctic Ids.) is very nearly related to H. magellanica 

 Hook. f. (Fuegia, Falkland Ids.). Others think these identical, but Hackel and 

 Pilger keep them distinct.
