Cytisus decumbens has a very wide range in the South of 
Europe, extending from France to Albania. It belongs to 
the sub-section Corothamnus, Briq., which is chiefly dis- 
tinguished by having all the leaves unifoliolate. Two other 
species besides the one here figured, C. procumbens, Spreng., 
and C. diffusus, Vis., possess this character, all the others 
being trifoliolate. Godron, Fl. de France, 1848, i. p. 360, 
indicates three varieties, characterized by the length of the 
pedicels and the size of the flowers.
