GENERA. 
I. STERCULIEA. 
1. Sterculia L.—Flowers polygamous, generally 5-merous ; calyx 
often petaloid, 5-fid or 5-partite, subcampanulate or subtubular, 
clavate or valvate. Corolla 0; stamens 10—» ; anthers sessile, 
extrorsely rimose, inserted without order at the summit of the erect 
column, sometimes incurved in bud. Carpels 5 (in female flowers 
small and sterile), opposite lobes of calyx ; ovaries free 2-2 -ovulate ; 
styles more or less joined together above, thickened stigmatiferous at 
apex. Fruit carpels distinct, stellate-patent, either ligneous or 
coriaceous, within folliculate rimose, or very thinly membranous, 
immediately or even before maturity dehiscing patulous. Seeds l-«, 
naked or winged ; albumen fleshy, 2-parted, adhering more or less to 
the exterior of the cotyledons ; cotyledons of thick embryo flat, or 
plano-convex, sometimes subundulate ; radicle short, opposite hilum, 
nearly or partly lateral.—Trees ; leaves alternate, entire, lobed or 
digitate; stipules usually small; flowers often in axillary, simple, 
or much oftener ramified racemose cymes ; central flower in cymes 
often female and early developed (4// the Tropical and Subtropical 
regions of the Globe). See p. 61. 
2. Tarrietia Br.—Flowers nearly of Sterculia, 1-sexual, 5-me- 
rous. Stamens 10-15, very much congested. Carpels 3-5, 1-ovu- 
late, samaroid at maturity, stellate-patent, indehiscent, dorsally 
produced into a wide-spreading falcate wing. Seed anatropous, 
albumen of Sterculia.—Lofty trees ; leaves digitate, 3—-5-foliolate, gla- 
brous or lepidote ; flowers small in much ramified axillary or lateral 
cymiferous racemes (Australia, Java). See p. 64. 
3. Cola Bauu.—Flowers nearly of Sferculia, 5- or more rarely 
4—6-merous; staminal column bearing at summit 10-15-anthers, 
on simple annulate adnate series ; cells parallel or superposed. 
Carpels 5-15, 2 -ovulate, swollen at maturity, inwardly rimose.
