Mac Lean, Esq.; several sub-varieties, marked as "yellow, mottled, white, or purple Potato"; but none are so luxuriant as Mr. Darwin's specimens. Juan Fernandez, Bertero; no flower; — Mr. Bertero remarks that it is possibly wild, the roots being bitter.

This and the four preceding are all large-flowered states probably of the true Solatium tuberosum, upon the pubescence, or form and number of the leaflets of which no reliance is to be placed. If so, its range is from an elevation near Lima in Peru, to the level of the sea at Chonos Archipelago, and iidand to the Andes of Mendoza in Chili.
