Nevertheless it would appear to be established by Mr. 
Baker’s researches that S. Maglia, which is invariably a_ 
coast plant, is not the origin of the Potato, which must be 
sought in the very closely allied S. tuberosum, a native of 
the Andes of Chili and Peru. I must refer the reader to 
Mr. Baker’s valuable paper on the tuber-bearing species of 
Solanum, in the twenty-first volume of the Journal of the 
Linnzan Society, for a full account of S. Maglia and its — 
allies. These extend northward to New Mexico, where 
S. Jamesii and Fendleri are found, and both of which have 
lately been brought into cultivation. 
Experiments are now being carried out under the auspices 
of the Royal Agricultural Society to improve the qualities of 
the Potato, especially as to its power of resisting attacks of 
the Potato disease, by crossing S. tuberosum with its allies, 
and amongst them with 8S. Maglia, which it is proposed to — 
distinguish in future by the name of the “ Darwin Potato.” 
As above stated, the drawing here given was made from 
plants raised from the original tubers given to the Royal 
Gardens by Dr. Sclater in 1862, which flower freely every 
autumn, and yield watery scarcely edible potatoes. 
Duscr. Nearly glabrous or sparsely pubescent. T'ubers 
subglobose or oblong, the largest one to one and a half 
inches long in longest diameter, surface smooth, red brown. 
Stem two feet high, erect, stout, branched, angled and | a 
winged. Leaves four to eight inches long; leaflets five to 
seven, the larger two to three inches long, ovate or oblong, 
acute, waved, lateral petiolulate, base oblique, rounded or 
cordate; basal leaflets small, stipuliform; intermediate 
small leaflets few or none. Cymes compound, many-flowered, 
pedicels slender. lowers ‘white, one inch in’ diameter. 
Calyz hirsute; lobes ovate-lanceolate, acuminate, longer 
than the tube. Corolla rotate; lobes short, broadly deltoid, — 
subacute. Filaments very short ; anthers orange-yellow, 
linear-oblong, Style twice as long as the stamens.—J. D. H.
