184 NATURAL HISTORY OF PLANTS. 



more rarely 3, lateral free ; anthers subbasifixed introrse 2-rimose. 

 Germen subcentral or excentric, shortly stipitate, free 2-ovulate; 

 style subulate; apex minute stigmatiferous. Fruit globose or 

 ovoid, sometimes slightly compressed ; subbaccate, glabrous or 

 velvety outside, pulpy within. Seed 1 (more rarely 2), slightly 

 compressed ; embryo greenish albuminous ; cotyledons fleshy or 

 leaf-like, sometimes folded ; radicle short straight. — Unarmed trees ; 

 leaves alternate imparipinnate; leaflets usually alternate coriaceous ; 

 stipules small or ; flowers in compound cymiferous much-branched, 

 terminal or axillary racemes ; bracts and bractlets small scale-like 

 caducous {All tropical regions). Seep. 129. 



00. Ceratonia L. — Flowers polygauio-dicecious ; receptacle short 

 broadly depressed turbinate, lined by a thick glandular orbiculate, 

 subpileiform disk. Sepals 5, very short imbricated in young bud, 

 finally free or hardly visible. Petals 0. Stamens 5, oppositisepalous 

 inserted below disk ; filaments free thread-like ; anthers 2-celled 

 introrse versatile 2-rimose. Germen central ; in male flower sterile, 

 shortly conical abortive ; in female and hermaphrodite, shortly 

 stipitate oo-ovulate : style short ; apex peltate, stigmatiferous. 

 Fruit elongated compressed, thick-coriaceous, indehiscent, both 

 sutures thick ; epicarp and endocarp glabrous ; mesocarp subcarnose 

 pulpy, produced into thick septa between seeds. Seeds a°, transverse 

 obovate compressed ; testa hard glabrous ; albumen copious horny ; 

 embryo greenish ; cotyledons flat ; radicle straight, shortly exserted. 

 — An unarmed evergreen tree ; leaves alternate paripinnate ; leaflets 

 paucijugate coriaceous ; stipules small lateral ; flowers in short, 

 solitary or fascicled racemes along wood of last year's branches ; 

 bracts and bractlets minute scale-like caducous {Inland regions).

VII. COPAIFEBE.E. 



01. Copaifera L. — Flowers small subregular ; receptacle minute, 

 convex or slightly dilated. Sepals 4 (highest sepal broadest), more 

 rarely 5 ; either much imbricated in aestivation, margins tapering ; 

 or slightly imbricated, margins obliquely cut , or more rarely valvate. 

 Corolla 0. Stamens 8-10, free, subhypogynous or a little perigynous ; 

 4-5-alternisepalous much shorter; filaments glabrous, inflexed in 

 bud ; anthers uniform introrse 2-celled 2-rimose versatile. Germen
