In size and habit this little species closely resembles the M. Antarctica (Part 1. p. 57. t. 38), but it is a much 

 slenderer, less rigid, and comparatively glabrous plant, with larger, though still very inconspicuous, and white 

 flowers. It evidently belongs, by its prostrate stems and axillary flowers, to the New Zealand group of the genus, 

 which, under the species alluded to, I have noticed as very different from that including the majority of the genus.

Hab. Clionos Archipelago, C. Darwin, Esq. 



The true Potato plant reaches the boundary to which the Antarctic Flora of South America is confined, and is 

 described as particularly abundant in the locabties whence Mr. Darwin's specimens were brought. The nature of the 

 present work forbids my dwelling on some of the peculiarities which mark the history and habitat of this plant ; and 

 I leave the subject with the less reluctance, because Mr. Darwin's own history of its discovery in an indisputably 

 native state is already pubbshed in one of the most interesting ' Journals of a Naturahst ' that has ever been 

 written. The following remarks apply wholly to the botanical affinities of the individual species now universally 

 cultivated in all temperate civilized countries. 



There are in South America several Solatia, so closely allied to the true Potato, that it is exceediugly difficult 

 to distinguish them specifically. Though differing materially in the shape of their calycine lobes, they display such 

 variation in these organs, that no specific value can be attached to them alone. The fruit may afford better charac- 

 ters, but that of many is at present unknown. The following is an enumeration of those South American Solatia, 

 allied to, or varieties of, the true S. tuberosum, which exist in the Hookerian Herbarium. I shall commence with 

 the specimens most similar to the common cultivated form.
