8—10/ long, broadest below the middle, pinnatisect in the outer half; the 
pinnules separated by broad round sinuses, sessile with a broad entire de- 
current base, the longest 1—11/2‘, oblong, obtuse or somewhat acute, notched 
in the middle portion, faintly crenate near the apex. Veinlets pinnate in
