TUBFR-BEARING SPECIES OF SOLANUM. 493 
of the ‘Transactions of the Horticultural Society,’ is also un- 
doubted Solanum Maglia, as just described. The history of the 
plant is as follows :—-Two tubers were sent to the Society from 
Chili in 1822 by Mr. Alexander Caldcleugh, Secretary to the 
Legation at Rio Janeiro. They were planted in the garden at 
Chiswick in richly-manured soil, and the produce was most 
abundant. The two plants in a single season yielded about six 
hundred tubers. These were of various sizes, a few as large or 
larger than a pigeon’s egg, others as small as the original wild 
ones, which were globose and under an inch in diameter. The 
flavour of them when boiled was exactly that of a young culti- 
vated potato. Sabine gives two excellent figures, a coloured 
one of the stem, leaves, and flowers, life-size, on plate 11, and 
on plate 9 figures of two tubers before and after cultivation. 
Although these figures are cited by Dunal in his Monograph in 
DeCandolle’s ‘Prodromus’ under S. tuberosum, there cannot be 
any doubt that they represent excellently the present type. 
5. SOLANUM COLLINUM, Dunal in DC. Prod. vol. xiii. p. 836.— 
This is fully characterized by Dunal from Bertero’s No. 1328, 
a plant labelled by the collector “ Papa cimarrona, incolis,” and 
gathered “In fruticetis collium locis incultis Quillota, regni 
Chilensis.” I have not seen an authentic specimen; but can- 
not by the description distinguish it from S. Commersoni, to be 
noticed directly. 
2. BRAZIL, URUGUAY, AND ARGENTINE REPUBLIC. 
1. SOLANUM Commersont, Dunal.—This is fully described by 
Dunal in DeCandolle’s * Prodromus, vol. xiii. p. 35, and by 
Sendtner in ‘ Flora Brasiliensis,’ vol. x. p. 12. It is noticed by 
Sabine in his paper on the Native Country of the Wild Potato, 
and is well figured by him from Commerson's original specimens 
on plate 10 of the 5th volume of the * Transactions of the Horti- 
cultural Society. I have not seen it alive, and the following 
description is drawn up from herbarium specimens. Stems 
dwarfer and more slender than in ordinary S. tuberosum, the 
rootstock bearing copious large tubers. Leaves sometimes, but 
not always, pseudo-stipulate, 5-6 inches long when fully deve- 
loped, with a naked petiole 1-14 in. long; 5-9 oblong acute or 
often obtuse thin leaflets, the terminal ones much the longest, 
the lowest pair much dwarfed; the rhachis entirely without any
