TUBER-BEARING SPECIES OF SOLANUM. 508 
distinet species from Central Mexico, described and figured by 
Sehlechtendahl in * Hortus Halensis,’ p. 5, tab.3. It has slender 
erect acutely-angled stems a span long, 9-11 oblong-lanceolate 
very acute sessile leaflets, with no small ones interspersed, lax 
few-flowered cymes, a small calyx with very acute lanceolate- 
deltoid teeth, and an ovoid remarkably pointed berry, three times 
as long as thick. It was collected by Schiede in stony ground at 
Malpays de Joya, fruiting in the month of September, and its 
tubers are said to be called * Papa cimarrona” by the natives. 
The following numbers of distributed Mexican collections seem 
to me to belong to forms of S. tuberosum, viz. :—F. Müller, 1673 ; 
. Linden, 240, 244; Galeotti, 1156, 1175; Bourgeau, 346, 1676, 
2864; Parry & Palmer, 633, 937, 938; Coulter, 1242. A plant 
gathered in the mountains of Costa Rica, Endres 196, which I 
have not myself seen, was identified by my colleague, Mr. N. E. 
Brown, with a slender-stemmed form of S. tuberosum with narrow 
leaflets and small flowers, found at Xalapa by Galeotti, which 
closely approaches the Peruvian S. immite and the Venezuelan 
S. colombianum. 
5. SOUTH-WESTERN UNITED STATES. 
1. SorANUM FENDLERI, 4. Gray.—This will be found described 
by Dr. Asa Gray at p. 285 of the 22nd volume of the second 
series of ‘ Silliman’s Journal,’ and under the name of S. tubero- 
sum var. boreale in the second volume of Gray’s * Synoptical Flora 
of North America, at p. 227. It is a native of the mountains of 
New Mexico and Arizona. The specimens in the Kew herbarium 
were collected in New Mexico by C. Wright, No. 1589, and in 
the mountains of Prinos altos by Mr. E. L. Greene. It has 
finely pubescent stems a span long, longer petioles than in typical 
S. tuberosum, 3—7 thin pilose broad ovate subacute leaflets, with 
few or no small ones interspersed, few-flowered cymes, small lilae 
corollas with deltoid segments, and globose fruit. Dr. Torrey 
states, in the ‘ Botany of the Mexican Boundary,’ p. 151, that in 
the wild plant the tubers are seldom more than half an inch in 
diameter. 
2. SOLANUM Jamesi, Torrey.—This is a thoroughly distinct 
species, of which we have grown a good supply at Kew this 
year from tubers furnished by the Agricultural Department at 
Washington. The following notes were taken from the living
