DIPTEB0CABPE2E. 



Conspectus of genera, 

 Suhord. I. ANCISTR0CLAI>i:2E. Ovary 2-celled, with a single erect ovule; fruit 

 adnate to the enlarged calyx. Scandent shrubs. 



1. Ancistrocladus. All the 5 calyx lobes more or less enlarged. 



S.ubord. II. DIPTEROQARPEjE. Ovary 3- rarely 1 -celled, with 2 pendulous ovules 

 in each cell. Trees, rarely erect shrubs. 



* Ovary inferior or nearly so, or with a broad base adnate to the calyx-tube : 

 nuts therefore for ^^ to f of their length adnate to the enlarged calyx tube. 



2. Anisoptera. Connective terminating in a bristle or acute gland ; 2 of the 5 

 calyx-lobes enlarging into long wings. 



** Ovary free, superior; nuts free, either enclosed in the enlarged calyx-tubo 

 or exposed and the calyx tube hardly enlai'ged. 

 Calyx-tube in fruit very enlarged, completely enclosing the nut. 



3. DiPTEROCARPUS. Two of the calyx lobes enlarging into long wings. 



O Calyx-tube in fruit not or almost not enlarged, the nuts either quite 

 exposed or closely surrounded by the enlarged calyx-wings, 

 t Calyx-lobes valvate in bud. 



4. Paeashorea. Stamens 12-^15, the connective mucronulate ; calyx-lobes all 

 almost equally enlarging and wing-like, stellately spreading, the nut quite exposed. 



t t Calyx-lobes imbricate and usually also twisted in the bud. 



X The 3 outer calyx-lobes in fruit longer than the 2 inner ones. 

 6. ShoreA. Corolla-lobes spreading ; stamens 35—50 or more ; anther-cells blunt, 

 the connective terminating in a bristle or penicellate sharp point. 



6. Pentacme. Corolla-lobes infracted at middle and forming a hemispherical 

 closed cup leaving only an opening for the protruding anthers and style ; stamens 15 ; 

 anthers 4-celled, the cells bristly, diverging from the subulate-pointed connective (anther^ 

 therefore 5-setose). 



X X The outer calyx-lobes in fruit much longer than the 3 inner 

 very small ones. 



7. HoPEA. Stamens 15 ; anther-cells entire at top, adnate to the more or less 

 prolonged connective. 



X >C X All the 5 calyx-lobes in fruit equally enlarged but not 

 longer than the fruit itself. 



8. Vatica. Stamens 15. Capsules by abortion 1- rarely 2-seeded.
