 with a dark crimson centre. Involucre campanulate, divided usually 

 to the middle in 10- 12 lobes, about half the length of the calyx. Ca- 

 lyx nearly an inch long, the lobes lanceolate. Capsule about 1' in 

 diameter, opening in 5 valves, .bearing the placentas on their centre 

 and their thin margins turned inwards so as to make the capsule ap- 

 pear 10-celled. 



Very common below 1,000° or 2,000° elevation, especially in moist places. A common 

 sea-coast tree in many tropical countries, and very abundant in the Pacific Islands. Na-
