RHS Index of Garden Plants indicates C. ramosa Nak., with ternate leaves,
and C. simplex Wormsk. ex DC with biternate leaves.

Other differences noted:
                       ramosa                simplex
height                  to 2m+               60-120 cm
leaflets               oblong-oval           ovate-suborbicular
raceme length          to 40 cm              to 30 cm
hardiness              z 9                   z 5

The rest of the descriptions are not comparable, so I can't really
tell if the person who did this genus really saw both plants.
Both are from Kamchatka, and I wonder if the zone designations are
really correct.  Perhaps someone with access to a copy of Index
Kewensis will track down Nakai's description of C. ramosa.  With luck,
there's a comparison to the older C. simplex description.
