Original diagnosis/description

Leaf pinnately compound, leaflets attached to stout rachis; prominent pointed spines (Figure 3) or scars of the base of spines (Figure 4A) present on the rachis; preserved leaflets narrow emerging straight from one side of the rachis at an acute angle (Figure 3, Figure 4); thick and prominent midvein in each leaflet; mid-vein paralleled by prominent secondary lateral veins, oblique and transverse cross veins also present on both sides of the secondary lateral vein.

“spino” is used to symbolize the presence of the spine and “pinnophyllum” refers to the pinnately compound leaves.
