1. DACRYDIUM Soland. 
Flowers dioecions, rarely monoecious. Staminate flowers terminal; 
microsporophylls leaves, scarcely or not at all changed; apicnlae large; 
male flowers rarely densely imbricate, anthers borne at the base of squa- 
mate axillary scales in the manner of Podocarpns; cells always 2. 
Pistillate flowers terminal or rarely on short axillar}- branches: car- 
pidia 1-several, free; ovule single, epimatium and covering turned and 
affixed to the base; epimatium almost wholly covering the young ovule; 
young ovules more or less inverted, micropyle facing toward the base of 
the carpidium, falselv erect; seeds surrounded by the base of the epmia- 
tium; testa hard; integument of the ovule always free from the epima- 
tium, not connate with it. Trees or shrubs. Leaves rarely ovate-lan- 
eeolate and mostly small, squailiiform or of different forms, m young 
state like linear loaves, in adult state transformed into squamiform leaves. 
Sixteen species in the Malayan region, New Zealand, and Tasmania.

Very distinct by virtue of its ovate-lanceolate falc.fonu leaves. The 
Borncan fonn, as I have seen it, has usually sliglitly larger leaves than 
the Philippine.
