480 NATURAL HISTORY OF PLANTS. 
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-foliolate ; folioles petiolulate, entire, coria- 
ceous, penninerved ; flowers rather large in compound axillary cymes’ 
(N. Caledonia’). 
50. Astrophyllum Torr. & Gr.'—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 ;‘ leaves 
subopposite, petiolate, digitate 5—-10-foliolate ; flowers axillary and 
terminal, solitary or subumbellate, long pedicellate’ (V. Mexico’). 
51. Peltostigma Waxp.’— Flowers hermaphrodite; receptacle 
thick, rather convex; perianth 8-leaved, very unequal, generally 
spirally inserted, closely imbricated; exterior 4 narrower and 
shorter, greenish; interior much larger, petaloid.? Stamens o, 
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 ;" styles slender, inserted 

1 A genus by gynæceum allied to Acronychia, authors are silent; hence doubtful. (Vid. 
germen one plurilocular ; differs especially in the 
number of stamens.

5 A genus very little known to us. Younger 
flowers (seen by us, perhaps belonging to 
another plant) seem to belong to Rutaceæ ; but

concave receptacle observed in them by us,
