light green with reddish margins. Bark roughish, light brown to grey. 

 Branches in whorls of three to five. Twigs green, with prominent scars of 

 fallen leaves. 



All parts of the tree exude a white latex when cut or broken. Each young 

 leaf is protected by two imbricate bracts, which fall away when the leaf 

 expands. These bracts may be 47 mm. long. The largest male racemes, 

 some of them 25 cm. long, do not have female flowers at their base, and 

 their lowest pedicels are elongated. The longest raceme noticed bearing 

 female flowers at the base was 15 cm. long. Capsules 15 mm. long, 3- to 

 4-celled, with a stigma to each cell. One capsule gathered had five cells. 

 This is the only tree on Sunday Island that partially sheds its leaves. From 

 May to July most of the leaves above 10 cm. across fall away. 



Flowers September to November. Fruit was gathered in April and 

 May, but probably matures as early as January.
