13. Solanum sambucinum Rydberg sp. nov. 
A perennial, with subterranean stolons and tubers; stem

14. Solanum lanciforme Rydberg nom. nov. 
S. cardiophyllum subsp. lanceolatum Bitter, Repert. 11: 440. 
IgI2. 
S. lanceolatum Berth.; Bitter, loc. cit., as synonym. Not S. 
lanceolatum Cav. 1794. 
I think that this very well deserves specific rank. The name 
originally proposed is preoccupied, however. It would not be 
advisable to adopt one of Bitter’s varietal names endotodandrum 
and amphixanthandrum, as these varieties and these names 
were based on the variable color of the anthers, a character of 
no value whatever. Both were described from individuals of 
Pringle 8509.

15. Solanum Ehrenbergii (Bitter) Rydberg sp. nov. 
Solanum cardiophyllum subsp. Ehrenbergu Bitter, Repert. 11: 
443- 1912. 
This is closely related to the preceding but the leaves are 
densely short-pubescent, the inflorescence more branched and 
the pedicels longer. The type was collected in Mexico by Ehren- 
berg, but without any definite locality and without number.
