Distribution of the Order, Genus, or Species. 



Auckland, Campbell, and Macquarie Islands, and closely allied to the 



Fuegian Luzula alopecurus. 

 Campbell Island and the Falklands, and Fuegia to the Andes of Quito. 



This Order is almost confined to Australia and South Africa ; very few 

 occur in New Zealand, one in Cochin-China, and one only in South 

 America. The African and Australian genera are mostly distinct. 



Of the nineteen species described, ten are from Australia, one from New 

 Zealand, one from Chili, one from Cochin-China, and seven from 

 South Africa. 



There are about 100 species of this genus, twenty-two of which are endemic 

 in Australia, and the rest in South Africa. 



Five species have been found in Australia, one of which extends to New 

 Zealand ; the rest (about a dozen) are endemic in South Africa. 



One endemic species each in New Zealand, the Auckland Islands, and 

 Chili. 



Two or three closely allied species inhabit Australia, New Zealand, and 

 Chili ; and Mann describes one from the Sandwich Islands. 



Tasmania, New Zealand, and Chili. 



Two species, one inhabiting Australia and New Zealand, and the other 

 Fuegia and Chili. 



The New Zealand Schcenus pauciflorus, and the Chilian Schcenus antarcticus, 

 are very closely related. 



Australasia, St Paul Island, South Africa, St Helena, and Extratropical 

 South America. 



Australasia, South Africa, and South America, and very near the widely 

 spread Scirpus setaceus. 



New Zealand, Amsterdam Island, and South America. 



New Zealand and the adjacent islands, the Falklands, and Fuegia. 



Australia and New Zealand; through the islands in the southern part of tin- 

 Indian Ocean to the Tristan da Cunha group, the Falklands, Fuegia, 

 and northward through the Andes to Mexico and the "West Indies ; 

 and one is found in the Sandwich Islands. 



Several of the Graniineaj of the Australasian and South American regions 

 are very closely allied, and * Hierochlos redolens and *Agrostis magel- 

 lanica (Agrostis antarctica) occur in both. 



The total number of species in the foregoing table inhabiting both Australasia and 

 South America is forty-eight, and the number of other essentially southern genera repre- 

 sented in the two regions by closely related species is forty-nine. These numbers are small 

 in comparison with the total number of genera and species inhabiting Extratropical 

 Australasia and Extratropical South America ; but their significance is more apparent 

 when we reflect that these genera and species are chiefly confined to New Zealand, 

 the contiguous islands, and the mountain flora of Victoria and Tasmania, and that all the 

 species of wider distribution common to the two countries are omitted. Forty-six out of
