germen ; anthers oblong, longer than filaments, introrsely 2-rimose. 

 Germen free, conoid; style apical simple; apex stigmatiferous, not 

 thickened ; cells 4, oppositipetalous ; ovules in each 2, descending ; 

 micropyle extrorse, superior. Fruit . . . ? — A shrub ; leaves oppo- 

 site, petiolate, digitate, 3-fbliolate ; folioles petiolulate, entire, coria- 

 ceous, penninerved ; flowers rather large in compound axillary cymes 1 

 (N. Caledonia'-). 



50. Astrophyllum Torr. & GR. n — Flowers hermaphrodite ; 4, 

 5-merous ; receptacle concave ? Sepals and petals same in number, 

 alternate, perigynous (?), valvate. Stamens 8, 10, 2 -seriate ; fila- 

 ments subulate; anthers ovate. Germen surrounded by 8-10-lobed, 

 little conspicuous disk ; lobes 4, 5, incurved above ; style ventral, 

 free at base, coalescing at apex, oblong-5-sulcate, stigmatiferous; 

 ovules in cells 2, collateral. " Cocci (aborted 2) coriaceous, dorsally 

 apiculate, with base of style rostrate ; endocarp cartilaginous, solute, 

 2-valved. Seeds ovate-globose ; testa nitid, black ; albumen fleshy, 

 scanty; embryo curved ; cotyledons large ; radicle short." — A humble 

 much ramified shrub, all prominently glandular-verrucose ; 4 leaves 

 subopposite, petiolate, digitate 5-10-foliolate ; flowers axillary and 

 terminal, solitary or subumbellate, long pedicellate 5 (JY. Mexico''). 



51. Peltostigma Walp. 7 — Flowers hermaphrodite; receptacle 

 thick, rather convex ; perianth 8 -leaved, very unequal, generally 

 spirally inserted, closely imbricated ; exterior 4, s narrower and 

 shorter, greenish ; interior much larger, petaloid. 9 Stamens cp, 

 slightly longer than perianth, and spirally inserted, free; anthers 

 introrse, 2-rimose. Carpels 8, inserted at summit of receptacle, 

 alternating with leaves of perianth ; germens free ; ovules in each 2, 

 descending ; micropyle extrorse, superior ; 10 styles slender, inserted
