free disk. Capsule nearly of Cunonia, septicidally 2-valved ; valves 

 cymbiform, gaping above within. Seeds go , sometimes few, oblong, 

 reniform or subglobose ; testa membranous, usually rough with 

 scattered hairs, sometimes subalate ; albumen, embryo and other 

 parts of Cunonia. — Trees and shrubs, glabrous or tomentose ; leaves 

 opposite, simple, 3-foliolate or imparipinnate ; leaflets coriaceous, 

 often glandular serrate ; rachis sometimes winged ; stipules varying, 

 sometimes broad, deciduous ; racemes axillary or terminal {Tropical 

 Continental and insular Asia and Africa, Oceania, New Zealand, 

 Tropical, Subtropical and Temperate South America). See p. 370. 



66. Spirseanthemum A. Gray. — Flowers nearly of Weinmannia, 

 apetalous, 4, 5-merous. Sepals valvate. Stamens twice as many 

 or as many (4, 5 alternisepalous, abortive). Glands 4-10, alternate 

 with stamens. Carpels equal in number to and alternate with 

 sepals, or 2, 3 (in male flowers rudimentary or sterile), free; 

 germen 1-celled ; style stigmatose at dilated apex ; ovules 1-5, 

 or co , 2-seriate in ventral angle. Follicles 1-5, dehiscent inwards. 

 Seeds 1-co, compressed; testa winged above or on both sides; 

 embryo albuminous. — Shrubs or small trees ; leaves opposite or 

 verticillate, petiolate simple ; stipules deciduous ; flowers in axillary 

 branching racemes ; pedicels articulate {New Caledonia, Islands of 

 Samoa, Viti, and neighbourhood). See p. 372. 



67. Tetracarpaea Hook. f. — Flowers 4-merous; receptacle rather 

 convex. Sepals free, imbricate. Petals alternate hypogynous ungui- 

 culate, imbricate. Stamens 8, 2-seriate hypogynous ; filaments 

 free ; anthers elliptical-oblong marginally rimose. Carpels 4, 

 oppositipetalous stipitate erect linear-oblong, 1-celled, terminating 

 in persistent short styles, stigmatose at obtuse apex ; ovules co , 

 inserted in internal angle of germen. Follicles 4, coriaceous stipit- 

 ate, longitudinally dehiscent inwards. Seeds co , minute elongated; 

 testa loose membranous slightly produced on both sides ; nucleus 

 minute ; embryo subglobose, nestling in base of fleshy albumen. — A 

 rigid glabrous low small shrub ; leaves alternate and opposite, 

 exstipulate, shortly petiolate, thickly coriaceous shining obovate- 

 oblong irregularly duplicate-serrate ; teeth subglandular ; flowers in
