LEGUMINOSH-CHSALPINIEZ. 171 
sepals 4, imbricated. Petals 8, 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 oblong 
subfalcate compressed thin indehiscent (?); placentary suture pro- 
duced into a narrow wing.—An unarmed tree; leaves paripinnate 
oo-foliolate ; flowers in short racemes usually fascicled at nodes of last 
year’s branches ; bracts and bractlets very caducous (Zropical Brazil).

IV. AMHERSTIEZ. 
25. Amherstia Watu.—F lowers hermaphrodite irregular resupi- 
nate ; receptacle long tubular, lined by a disk. Sepals 4, inserted at 
top of tube, petaloid unequal, imbricated in zstivation. Petals 5, 
free; 3 posterior broad membranous, the highest innermost largest 
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, -ovulate; style slender, revolute 
in bud ; apex capitellate stigmatiferous. Legume elongated falcate 
plano-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 (Jndia). See p. 92. 
26. Humboldtia Vanu.—F lowers 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-
