In the United States National Herbarium there is a specimen 
which bears the following label: 
“1132. Solanum stoloniferum Schlecht. et Bouche. 
(Solanum squamulosum Martens et Galeotti). Mexico. C. 
Ehrenberg.” 
This specimen had come from the Botanical Museum at Ber- 
lin. The specimen does not agree with the description of S. sto- 
loniferum, but well with that of S. verrucosum. Schlechtendahl,* 
who had before him Ehrenberg’s specimens of both species, stated 
that the flowers of S. stoloniferum had white flowers and S. verru- 
cosum bluish-purple. In the specimen mentioned in the National 
Herbarium the flowers are purple and the leaves bearing the 
strong hairs of the latter species. Furthermore, S. squamulosum 
is supposed to be a synonym of SS. verrucosum, not of S. stolont- 
ferum. Evidently there must have been some error committed 
in labelling the specimen. Perhaps it represents part of the 
original collection of S. verrucosum made at Mineral del Monte. 
The species was originally published in the Index Seminum of 
1839, though the description is very meager. In that publication 
no reference was made to Ehrenberg’s specimen and the species 
must therefore be regarded as based on the cultivated specimens, 
which according to Schlechtendahl would be illustrated together 
with another species with acute fruit. These illustrations were 
published two years later, when the author stated that the seeds 
were collected by Ehrenberg at Mineral del Monte. Bitter re- 
garded one of Ehrenberg’s herbarium specimens as the type, and 
drew his description from that. Schlechtendahl’s illustration in 
*Linnaea 19: 274. 1847.
