Leaf scale
Lrac int	cm	Rachis length
ratio L	cm cm−1	Ratio of petiole length to rachis length
Nb max	–	Number of leaflets per leaf
δsf	–	Evolution of rachis curvature along the rachis
δAmax	degrees	Declination angle at rachis tip
θa	degrees	Leaf twist at rachis tip
∆a	degrees	Leaf deviation at rachis tip
d Lft	–	Evolution of inter-leaflet distance along the rachis
Leaflet scale
LB int	cm	Leaflets length at point B†
WB int	cm	Leaflet maximum width at point B
p L	–	Relative position of the longest leaflet on rachis
p W	–	Relative position of the largest leaflet on rachis
αC	degrees	Leaflet axial insertion angle at point C
xm int	–	Relative position of maximum width on leaflet

* Point C represents the transition point on the leaf between the petiole and the rachis.

^† Point B represents the transition point on the rachis where the cross section becomes circular.
