 A native of China and Japan, introduced into the Philippines for orna- 

 mental purposes and now occasionally cultivated in Manila and in other 

 large towns in the Archipelago. It never produces flowers or fruits in 

 the Philippines so far as our records show.

Batan Islands and northern Luzon to Palawan and Mindanao. Chiefly 

 J along or near the seashore, sometimes in forests ; of rather local occurrence. 

 3 Malaya to Polynesia. 

 * The common coastal form may not be specifically distinct from C. circi- 

 nalis Linn. A form from the forests of Mt. Mariveles (Merrill 3257, Whit- 

 ford 269, 1325, etc.), with small c? cones and small fruits may be specifically 

 distinct. A second form from Mindoro and Batangas with small fruits 

 jH^ay also be distinct {B. S. 22391 Ramos).
