Hab. Strait of Magalhaens, and throughout Fuegia, Commerson, Banks and Solander, and all succeeding 

 voyagers. Falkland Islands, D'Urville, Sfc. 



The leaves of this plant vary from two to four, three being the prevailing number. The flowers, also, are 

 very much larger in some specimens than others, and dissimilar in colour and spotting. Poeppig's Pogonia tetraplnjlla. 

 from South Chili, is decidedly only a state of Codonorchis Lessonii, the glands on the labellum affording no more 

 constant character in this plant than in the beautiful ChUogloUis of Tasmania.

One of the most abundant and elegant plants in the Falkland Islands, where the grassy plains are, in the 

 spring month of November, almost whitened by the profusion of its pendulous snowy bells. 



A very similar species, if not the same, seems to be common in Chili, from Valparaiso to Concepciou ; but 

 its flowers are smaller than in the majority of the Falkland Island specimens.
