Caides plerique unciales, exemplaribus Falklandicis 3-4 pollicares, ramosi, rigidi, e foliis subrecurvis squarrosi. Folia i line, longa, kete viridia, inferiora saepe discolora. Umbetta. 6-8-flora. Pedicelli riorum brevissimi, post anthesin verosirniiiter elongati, ut in icone Cavanillesii. Petala oblonga, subobtusa. Stylopodia majuscula. Fructm immatums ad suturam vix contractus, dorso planiuscidus.

It it exceedingly difficidt to um'avel the synonymy of the species belonging to this genus. The name of Chamitis was applied to A. filamentosa, Lam., and A. trifurcata, Hook., by Gaertner in 1788, adopted from the MSS. of Banks and Solander. These voyagers discovered a third species, Chauitis trifurcata, a name which Gaertner has accidentally affixed to his plate of A. tricuspidata. The Azorella caspitosa, according to a statement made by Cavanilles, 1. c, was probably first detected by Commerson; the specimens figured by the author just quoted are from the Cordillera of Chili, and Mr. Darwin having gathered it at Port Desire, and Capt. King at Cape Fail-weather, it is probably a very general plant throughout the southern parts of Patagonia.

The genus Azorella was founded upon this species and is probably a name of Commerson 5 s ; for Lamarck, who adopted it in 17 S3, remarks that, not knowing the fnut, he cannot see how it differs from Hydrocotyle.

The present is a very common plant throughout Fuegia and the Falkland Islands. Gaertner mentions having examined specimens in the Bauksian Herbarium, with three carpels.
