taste, and as useful as that of the old kind." Then follows a 
description, which quite fits for S. tuberosum except that the 
berry is stated to be oblong, compressed, and two or three inches 
in length. No specimens appear to have been sent to Europe, 
and the plant has not since been heard of. It may perhaps be 
identical with S. Otites, Dunal. 
Solanum Maglia.—A plant in the Kew herbarium from Mr. 
W. Nation, received in 1863, labelled “ Sandy hills of Lima, 
common," I eannot distinguish from the Chilian S. Maglia. 
The following note, which accompanies a bottle of Chunos or 
dried Peruvian potatoes in the Kew Museum, may also be worth 
placing on record :— 
“Extract of a letter from Mr. W. Atherton, Liverpool, dated 
Sept. 17, 1850, to the Seeretary of the Royal Institution.—The 
natives of the interior of Peru prefer the Chuno to the potato in 
any other form. It is universally used in the departments of 
Cuzco, Lampa, Pimo, Chuquito, La Paz, Potosi, and elsewhere. 
The manner of preparation, which mostly takes place at a great 
elevation above the level of the sea, is to expose the potatoes, 
throwing water on them. They become frozen during the night, 
and the operation is repeated three successive evenings. They 
are then dried in the sun, the rarefaction and dryness of the air 
favouring this most effectually. Thus they are ready for use or 
keeping." 
4. MEXICO. 
1. SOLANUM VERRUCOSUM, Schlecht.—This is fully characterized 
and figured by Schlechtendahl in ‘ Hortus Halensis.’? The native 
locality is stated to be “In regione Mineral de Monte Mexici 
satis frequens, ad vias, in sylvis, muris, etc., a Julio ad Oct. 
florens. C. Ehrenberg.” M. Alphonse DeCandolle has recorded 
in the ‘Revue Horticole’ and elsewhere how it was cultivated 
for many years by peasants in the neighbourhood of Geneva, and 
how the cultivation was finally abandoned on account of the 
smallness of the tubers, and because they did not, as was hoped, 
resist the disease. The tubers, he states (Geog. Bot. vol. ii. 
p. 815), are smaller and later in their development than in ordi- 
nary S. tuberosum, of excellent taste, with yellow flesh. The 
petiole is longer and the leaflets are fewer than in typical tube- 
rosum, ovate, acute, densely hairy beneath, and the interspersed 
smalllleaflets are not invariably present. The flowers are large
