RYDBERG: SOLANUM IN MEXICO AND CENTRAL AMERICA 175 
30. SOLANUM APPENDICULATUM Humb. & Bonpl.; Duaal . 
Solan. Syst. 5. 1816. 
There are at least three species in Mexico, which have been 
taken for S. appendicularum. Of the three known to me, there 
is only one which agrees with the original description and that 
in De Candolle’s Prodomus. The other two do not agree in 
the following particulars: “‘foliis . . . I-2 jugis, segmentis 
oblonzgis acuminatis, utrinque acutis, supra adpresse_pilosius- 
culis, subtus in venis pubescentibus; . . . Stylus stamini- 
bus subaequalis;’’ for the second has 7 leaflets, densely pubescent, 
and in the third the style is twice as long as the stamens. The 
first one which I regard as the true S. appendiculatum, is well 
represented pi 4922 from Oaxaca. The type came 
from Hidalgo
