150 RYDBERG: SOLANUM IN MEXICO AND CENTRAL AMERICA 
5. SOLANUM STOLONIFERUM Schlecht. & Bouché, Verh. Beférd. 
Gartenb. Preussen 9: 317. pl. 2. 1833 
Bitter seems not to have seen any native specimen except 
those collected by Schiede and Deppe. There is, however, no 
uncertainty as to its identity as the original publication contains 
a good illustration. Furthermore, there is a cultivated specimen 
in the Columbia University herbarium from the Botanic Garden 
at Brasel. A specimen collected on ballast, near Communipaw 
Ferry, New Jersey, by Addison Brown might belong to it. The 
only Mexican specimens I have seen are the following:

base, densely white-hairy on both sides, the lowest one or 
two pairs much reduced; ean smaller segments

Type collected in the ecules of San Luis Potosi, 1878, Parry 
& Palmer 632 (U.S. Nat. Herb. 42677). 
This species is most closely related to S. Fendleri, but differs 
in the dense pubescence with long white hairs. 
7. SOLANUM FENDLERI A. Gray, Am. Journ. Sci. II. 22: 285. 1856 
S. tuberosum boreale A. Gray, Syn. Fl.2):227. 1878. 
S. boreale Bitter, Repert.11:459. 1912. 
The original specimens of S. Fendleri had deep violet corollas 
but the color varies considerably and white-flowered specimens 
are as common as those with purple or bluish shades. Bitter 
thought that the white-flowered specimens represented a distinct 
species and adopted for this Dr. Gray’s varietal name, boreale. 
Though the white-flowered specimens often are less hairy and the
