‘he species here figured is confined to the Lepontine 
Alps in the vicinity of Lake Como on the borders of Italy 
and Switzerland, where it grows on mountain sides at high 
altitudes. It forms by itself the subsection Emeroides, 
Briquet, characterised by the solitary or geminate, axillary 
flowers, just as G. nigricans is the solitary species of the 
subsection Eulembotropis, Briquet, which has the flowers 
arranged in terminal leafless racemes. 
The limits of Genista and Cytisus have been variously 
drawn by botanists, and some, including Baillon, combined 
them. Briquet, however, in his Les Cytises des Alpes 
Maritimes, places the species with a well-developed strophiole 
in Cytisus, and those with a rudimentary strophiole, or 
none, in Genista.
