RYDBERG: SOLANUM IN MEXICO AND CENTRAL AMERICA 153 
Hortus Halensis, drawn from the cultivated material, resembles so 
closely our duplicate of the type of Bitter’s var. iopetalum, that I 
regard the latter as typical S. verrucosum. The Ehrenberg 
specimen, however, does not differ, as far as I can judge, very 
much from them.

10. Solanum Ervendbergii Rydberg sp. nov. 
A perennial with gas dele rootstocks and tubers; 
stem low, less than 2 dm. hi ee ee oe leaves 
6-10 cm. long, the rachis sca sic age ned, puberulen 
leaf-segments ect 7, distinctly netioleled. the blades ae 
ceolate, somewhat oblique at the base, 2-3 cm. long, acute or 
somewhat acuminate, belch on both sides; intermittent 
i anaetade not present; peduncle 6-7 cm. long, slender, puber- 
ulent; racemes 4—7-flowered ; calyx strigose, 3-3.5 mm. long, 
the Ne aes lanceolate, epee than the tube, acute; corolla white, 
pentagonal, about I cm. wide, the lobes broader than long. 
Type collected at Seca near Tantoyuca, Vera Cruz, 
in 1858, Ervendberg 175 (Gray Herbarium). 
The type was first determined as S. Jamest Torr.?, then 
changed to S. appendiculatum Dunal? Somebody has later 
determined it as S. stoloniferum, which name again has been 
changed by Wight to Solanum Jamesii Torrey. It has nothing 
to do with S. appendiculatum which is a climbing vine with sub- 
basal articulation on the pedicels. In habit it resembles S. 
Jamesii but the leaflets are stalked and the corolla pentagonal 
and not star-shaped. S. sioloniferum has ovate leaf-segments 
and larger flowers. It is probably most closely related to S. 
verrucosum, but the plant is more slender, with much smaller 
corolla, and the leaves are puberulent not hirsute and without 
intermittent segments. 
* On this specimen in the U. S. Nat. Herb., the number has been changed 
from 753 to 633, which change might have been unwarranted. Number 633 
in the Columbia University herbarium belongs to S. cardiophyllum.
