352 NATURAL HISTORY OF PLANTS. 



hypogynous ; lobes nearly free, or only connate at very base, valvate ; 

 2 superior a little broader. Petals shortly unguiculate ; standard 

 orbicular or reniform ; wings obliquely obovate or oblong ; keel 

 shorter than wings, obtuse. Stamens 10, free, scarcely perigynous. 

 Germen sessile or stipitate ; ovules 2 ; funicles elongated, thickened 

 at apex, dilated into obturators above micropyle, curved or folded 

 one upwards, one downwards ; style incurved more or less dilated at 

 base ; apex minutely stigmatiferous. Legume ovoid or subglobose 

 inflated, oblique at base. Seeds 1, 2, exarillate. — Shrubs or under 

 shrubs ; leaves alternate, simple digitate, or pinnate ; terminal 

 leaflet sessile ; stipules small or ; flowers 1 racemose in superior 

 axils, or racemose or subumbellate at ends of branches ; bracts small 

 bractlets inserted at bottom of pedicel or half-way up {Australia-). 



250. Jacksonia E. Br. 3 — Eeceptacle obconical very short. Calyx 

 gamosepalous at very base ; lobes elongated equal or 2 superior 

 broader ; praefloration valvate. Corolla and stamens of Burtonia. 

 Germen sessile or stipitate ; ovules 2, very rarely 3-6 {Piptomeris*), 

 reniform, shortly funiculate ; style subulate incurved, apex minutely 

 stigmatiferous. Legume ovate or oblong, compressed or subturgid. 

 Seeds 1, 2, exarillate. — Shrubs or undershrubs, rigid leafless, twigs 

 sometimes angular rush-like, or spinescent, sometimes phyllodineous 

 simulating leaves; leaves minute scale-like; flowers 5 scattered 

 along branches or in terminal racemes or spikes ; bracts and 

 bractlets small scale-like {Australia 6 ). 



251. Sphaerolobium Sm. 7 — Eeceptacle obconical, often elongated. 

 Calyx gamosepalous ; tube longer {Roea*) or shorter than lobes ; 

 lobes imbricate ; 2 superior larger or very large, connate. Corolla 

 and stamens of Burtonia, very perigynous. Germen stipitate ; ovules 

 2 (of Jacksonia) ; style incurved subulate or dilated at base, above
