Rather a scarce plant and perfectly distinct from the following, with which it has been strangely confounded, 

 partly because Gaertner inadvertently applied the name of A. tricuspidata to his figure of Banks' A. trifurcata, and 

 partly owing to the confusion in wliich the whole group to which it belongs has long been involved, and the refer- 

 ence of many different umbelliferous plants with a tufted habit and simple umbels, by Lamarck, to the Bolax glebaria 

 of Commerson.

Found at all elevations, both in Fuegia and in the Falkland Islands, and so much resembling Coloban tints 

 subulatus, that the two plants have often been taken for each other and for the Mniarum fascicidatum, Forst., a New 

 Holland and New Zealand plant, which is hence erroneously described as being also a native of the Strait of 

 Magalhaens. The fruit of this species certainly differs from that of the two former, and they, again, from the carpels 

 of A. ecespitosa and the following ; I have, however, brought them all under one genus, feeling assured that the 

 details of the form of the mericarps do not afford the important characters in this group that they do in some 

 other UmbellifertB.

The fruit of this plant is so dorsally compressed and contracted at the sutures, as almost to justify its being 

 removed from this genus and even group. The calycine teeth and the styles are rather longer than is usual in 

 Azorella ; still, as mentioned above, the fruits of almost all the species that I have examined differ so widely from 

 one another, that to separate this or either of the former would involve the complete dismemberment of a genus, of 

 which all the species, except the following, are very closely allied. 



Azorella Selago is the most abundant plant in Kerguelen's Land, covering the rocky ground close to the sea 

 with brown masses many feet in extent, and often so soft that the traveller plunges into or through them up to the 

 middle. Like the curious Bolax glebaria of the Falkland Islands, the living part of the plant forms a crust over a
