496 MR. J. G. BAKER ON THE 
et Chilensis regni cultis et in collibus Chaneay ad Jequam et 
Pasamayo predia;” and in a letter to Lambert, cited by Mr. 
Cruikshanks in Hooker's * Botanical Miscellany,’ vol. ii. p. 203, 
Pavon writes :—* The Solanum tuberosum grows wild in the envi- 
rons of Lima, and fourteen leagues from Lima on the coast." 
There are two sheets of fine specimens gathered by Pavon in the 
herbarium of the British Museum, labelled “ Patatas del Peru,” 
on which I took the following notes :—Stem stout, elongated, 
flexuose, slightly pilose. Leaves pseudo-stipulate, 6-8 in. long, 
including the 1-13 in. petiole; leaflets broad ovate, cordate at 
the base, acute, thin in texture, green and thinly pilose above, 
grey and densely pilose beneath; main ones 9-11, the end one 
24-3 in. long, 18-21 lines broad; lowest pair very small; 
interspersed small leaflets many. Flowers in a dense long- 
peduncled compound cyme; pedicels articulated at the middle. 
Calyx jin. long, densely pilose; segments lanceolate-deltoid, 
twice as long as the tube. Corolla white, under an inch in 
diameter; teeth deltoid, half as long as the tube. Anthers 
s in. long. Style much exserted. This, I should say, differs 
from the typical Chilian S. tuberosum about as much as one of 
the garden forms of potato differs from another. The following 
dried specimens, which I have seen, from different parts of the 
Andes all seem to me mere forms of S. tuberosum :—(1) A series 
of eight different plants from Peru, gathered by Maclean, labelled 
“Mottled,” “Yellow (Amarilla),” * White (Blanca) ” (these 
three I presume to be cultivated plants), * Guayruma,” * Cho- 
rilos" < San Mateo,” < wild, white-flowered, Huamantanga, 
11,000 feet,” and “wild, blue-flowered, Huamantanga, 11,000 feet.” 
(2) A dwarf slender subglabrous form, with ovoid fruit and 
small lilac flowers, in Spruce's collection from the Andes of Quito, 
No. 6123, “In monte Carguairago, alt. 12,000 pedes. This is 
one of the Sacha-papas, or wild potatoes. Both tubers and 
berries are edible ; the former reach the size of a pigeon's egg." 
(3) Mandon, 397, * Andes of Bolivia, Prov. Larecaja: viciniis 
Sorata, in scopulosis montis Illampu, Lancha de Cochepata. 
Regio subalpina, 3500 metres, Nov. 1878.” (4) Matthews, 847, 
* Peru, amongst rocks, Lomas of Amaneaes, J uly." (5) Matthews, 
772, “ Peru, Cuesta de Purruchuca, April:" a subglabrous form, 
with very large terminal and numerous very small side-leaflets, 
large white flowers, and a very long style." (6) Matthews,
