176 NATURAL HISTORY OF PLANTS. 



nately long-unguiculate ; claws indnplicate-valvate ; blades oblong 

 undulate imbricate. Stamens go , inserted on hemispherical re- 

 ceptacle above perianth, free. Germen long-stipitate ovoid ; 

 stigma sessile, large, discoid ; placentas 2—4 ; ovules go . Berry 

 oblong-elliptical, 2-4-ribbed. — Shrubs, climbing or erect ; leaves 

 alternate, 3-5-foliolate ; stipules or small caducous ; flowers in 

 long-pedicellate corymbs {Tropical Africa). See p. 157. 



14. Emblingia F. Muell. — Calyx campanulate, 5-lobed, split 

 down to base in front. Petals 2, alternating with posterior sepal, 

 united behind into an ascending slipper-shaped corolla ; receptacle 

 produced behind perianth into a gynophore with glabrous glandule 

 at base behind ; gynophore much elongated flattened bowed, concave 

 behind; apex dilated around germen into a disciform, 6-12-crenate 

 or shortly lobed ring ; anterior lobes 3-6, obtuse pubescent sterile ; 

 posterior 3-5, bearing a small 2-celled introrse 2-rimose anther. 

 Germen 1-locular; placentas 2, 8-ovulate ; style short, slightly 

 enlarged into a stigmatiferous, 2-lobed lamina. Drupe subglobular- 

 compressed, inverted, curved down into calyx ; mesocarp thin ; 

 putamen rugose or prickly, 1 -seeded. Embryo involute. — A pros- 

 trate scabrous-hirsute undershrub ; leaves crowded, simple, opposite, 

 or subopposite ; flowers axillary, solitary ; peduncle short, slender 

 {West Australia). Seep. 158. 



III. MiERUE^E. 



15. Mserua Forsk. — Flowers regular, hermaphrodite, or more 

 rarely polygamous ; receptacle concave, obconical or tubular ; disk 

 lining receptacle, and scarcely prominent from its mouth {Streblo- 

 carpus), or produced into a simple or torn edge {Eumcerua). Petals 

 or 4 {Streblocarpus). Stamens co , perigynous ; filaments free or 

 connate at base; anthers introrse, 2-rimose. Germen stipitate, 

 inserted at bottom of receptacle, 1 -celled; placentas 2—4; ovules few 

 on each placenta {Courbonia), or more frequently co ; stigma sub- 

 sessile. Berry stipitate, ovoid {Niebuliria) or subglobular {Cour- 

 bonia), more frequently cylindrical torulose, more or less constricted 

 between the seeds {Eumcerua). Seeds solitary or few {Niebuliria,
