The leaf petiole is brown and grooved adaxially (upper side).

The leaf color is medium green, sometimes with a silvery or bluish cast.

The ultimate leaflets are oblong to linear with the largest 3 to 7 mm in length, and hairless on both upper and lower sides.

It grows on rocky slopes and ledges, usually on igneous substrates, at elevations from 300 to 2000 meters.
