The foliage alone is insufficient to distinguish this species from a small state of C. FothergilUi, but they are very dissimilar in the calyx and size of the corolla, the sepals of the former being very broad and almost cucullate, covered externally with a viscid yellow tomentiun, while in C. nana, they are smaller, narrower, and simply pubescent. The corolla of C. nana almost equals that of C. Banvinii, to which, in every respect, it is nearly allied.
This species has been also found at Cape Fairweather by Capt. King.

Habitus C.polyrhizce, corolla: iis C. FothergilUi forma similes sed majores, speeiosa;, maculatae. Benth. I.e.
Much the handsomest species of the small section "Scajiosa," to which all the Antarctic Calceolaria belong. Though very distinct at first sight from the former, the individual parts are so liable to vary that it becomes almost impossible to draw up an absolute distinctive character. For instance, the leaves in one specimen have the same form as in a Cape Fairweather individual of C. nana, and, though more glabrous than in most states of the latter plant, they are not universally so; the corolla; are quite alike in the two, and the difference in the length of the filaments is hardly appreciable. The calyx of C. Darwinii varies exceedingly in the size and form of its segments, they are sometimes large, broad, and obtuse, as in C. FothergilUi, or small and narrow like those of C. nana.

Of this plant I have seen no Falkland Island specimens. It is also a native of Port Desire on the coast of Patagonia, where Mr. Darwin gathered it.

Very abundant between the latitude of Valparaiso and the Strait of Magalhaens, though confined to a narrow belt, which runs obliquely across the continent of South America, from lat. 33°, to lat. 53°. In the northern half of its range, between the parallels of Valparaiso and Chiloe, it is chiefly confined to the west of the Andes ; in the southern half, between the latter locality and the Strait of Magalhaens, it crosses to the east side of South America; thus avoiding equally the wet, cold, and stormy latitudes of South-west Chili and Fuegia, and the arid plains of Patagonia.
