sepals 4, imbricated. Petals 3, posterior ; highest petal innermost 

 smallest. Stamens 10, diadelphous (9-1); highest filament free; 

 remainder united to form a sheath, cleft above ; anthers uniform in- 

 trorse 2-rimose. Germen central stipitate pauciovulate ; style thin 

 twisted, clavate at apex; stigma minute terminal. Legume oblon"* 

 subfalcate compressed thin indehiscent (?) ; placentary suture pro- 

 duced into a narrow wing. — An unarmed tree ; leaves paripinnate 

 co-foliolate ; flowers in short racemes usually fascicled at nodes of last

25. Amherstia Wall. — Flowers hermaphrodite irregular resupi- 

 nate ; receptacle long tubular, lined by a disk. Sepals 4, inserted at 

 top of tube, petaloid unequal, imbricated in aestivation. Petals 5,

 broadly cordate ; 2 anterior minute rudimentary. Stamens 10, in- 

 serted with perianth, diadelphous (9-1) ; filament superposed to 

 standard free ; remainder coalescing into a sheath, cleft above ; 

 5 oppositipetalous much the smallest ; anthers introrse 2-celled 

 2-rimose. Germen stipitate, very excentric, inserted on posterior 

 wall of receptacle near margin, co-ovulate ; style slender, revolute 

 in bud ; apex capitellate stigmatiferous. Legume elongated falcate 

 piano-compressed coriaceous woody 2-valved ; placentary suture thick 

 dilated. Seeds transverse ovate-orbiculate compressed exarillate ; 

 embryo exalbuminous ; cotyledons flat ; radicle short straight in- 

 cluded. — An unarmed tree ; leaves alternate paripinnate ; leaflets 

 large coriaceous ; stipules leaf-like caducous ; flowers large in ample 

 loose terminal pendulous racemes ; bracts caducous ; bractlets large 

 coloured persistent, free or slightly connate at base inclosing bud, 

 finally spreading (India). See p. 92. 



26. Huinboldtia Vaiil. — Flowers of Amherstia, but much smaller ; 

 stamens 10, free, all fertile or more usually 5 oppositipetalous 

 reduced to small sterile filaments or absent. Germen pauciovulate. 

 Legume oblong oblique or falcate compressed coriaceous 2-valved. 

 Seeds few compressed exarillate. — Unarmed shrubs ; leaves alter- 

 nate paripinnate; stipules leaf-like, obliquely reniform or semi-
