502 MR. J. G. BAKER ON THE 
Chiswick in 1847. I cannot see that it is more than a slight 
variety of S. tuberosum, closely allied to S. verrucosum. 
9. SOLANUM UTILE, Klotzsch.—This will be found fully de- 
scribed at page 677 of the 13th volume of DeCandolle's * Pro- 
dromus.’ It came from the mountains at an altitude of 10,000 feet 
above sea-level from the Rio Frio, between Puebla and the city 
of Mexico. I have not seen authenticated specimens, but cannot 
make out from the description that it differs in any way essen- 
tially from S. tuberosum. 
6. SOLANUM SQUAMULOSUM, Mart. § Gal., from alpine woods 
at Real del Monte, Mexico, No. 1221 of Galeotti’s distributed 
collection. Of this the description is so brief that it is impossible 
to judge from it. Dunal queries whether it is not a form of 
S. verrucosum. 
7. SOLANUM CARDIOPHYLLUM, Lindley.—This was received from 
Herr Uhde along with S. demissum, and is described and figured 
by Lindley at pp. 70 & 71 of the third volume of the * Journal of 
the Horticultural Society.’ I have examined the type specimen 
in the Lindley herbarium at Cambridge. It has the general 
habit of S. tuberosum ; but there are no small leaflets interspersed 
amongst the large ones, and the shape of the corolla is quite 
different, so that it is clearly distinet specifically. The following 
is a summary of its characters :—Rootstock producing globose 
white watery tubers an inch in diameter. Whole plant quite 
glabrous. Stems stout, erect, herbaceous, above a foot long, 
Leaves glabrous, very dark green, half a foot long, conspicuously 
pseudo-stipulate ; petiole above an inch long; leaflets 5, large, 
ovate acute, the end one 2-25 inches long and nearly as broad, 
the side ones distinctly stalked, the lower pair much the smallest ; 
no small ones interspersed. Flowers in compound cymes, with 
short peduncles and pedicels. Calyx glabrous; teeth deltoid, as 
long as the tube. Corolla white, 2 in. diam., with lanceolate- 
deltoid acute segments as long asthetube. Stamens longer than 
the corolla-tube. Style scarcely longer than the stamens. A 
native of the mountains of Central Mexico, at an elevation of 
8000-9000 feet. 
8. SOLANUM OXYCARPUM, Schiede.—This is a little-known very
