 white beneath with dark nerves; nervules slender 'parallel; petiole 2-10 in. Cymes 

 from the upper axils, 2-4 in. diam., on peduncles 1-3 in. ; fern, heads \ in., white or 

 reddish in fruit. 



6. D. ceylanica. Hook. f. ; branches very stout, tips and petioles- 

 pubescent, leaves orbicular cuspidate quite entire, base rounded or cordate,

A tree. Branchlets as thick as the little finger. Leaves 3-4 in. diam. ; petiole

 branches. Cymes with stout peduncles 1J-2 in., each bearing 3 rarely more stoutly 

 pedicelled fern, heads in. diam. The orbicular leaves, the shorter stouter petioles 

 and peduncles, and the much larger fruiting heads distinguish this from D. Wai- 

 lichiana.
