Flowers monoecious or subdioecious. Petals present. Male flowers : 

 Calyx globose and closed in bud, opening valvately into 2-3 lobes. 

 Petals 5, longer than the calyx. Stamens 8-20, inserted on a conical 

 receptacle, the 5 exterior opposite the petals and alternating with small 

 glands ; iilaments free or partially connate, short or elongated ; anthers 

 erect; cells parallel, dehiscing longitudinally. Rudimentary ovary 

 absent. Female flowers : Perianth as in the male. Disk inconspicuous 

 or consisting of minute glands alternating with the petals. Ovary 

 2-5 -celled ; styles usually divided into 2 thick branches; ovules solitary 

 in each cell. Fruit large, drupaceous, indehiscent ; exocarp fleshy ; 

 endocarp crustaceous or woody, 2-5-celled or 1 -celled by abortion. 

 Seeds with a thick woody testa ; albumen thick, hard ; embryo 

 straight ; cotyledons broad and flat. — Trees with stellate or subsimple 

 hairs. Leaves alternate, long-petiolate, large, 5-7-nerved from the base, 

 entire or lobed ; petiole bigiandular at the apex. Flowers in lax cymes ; 

 cymes crowded at the apices of the branchlets. 



Species 4, natives of Eastern Asia and the Pacific Islands, the following two 

 cultivated in Tropical Africa. 



Leaves pubescent with adpressed simple hairs when young, when 

 lobetl then with a large sessile gland at the base of each 

 sinus between the lobes; flower-buds pointed, glabi'escent; 

 petals nearly 1 in. lojig ; stamens about 10 . . . 1. A. cordata. 



Leaves pubescent with stellate hairs when young, when lobed 

 then without a gland in the sinus between the lobes ; 

 flower-buds obtuse, tomentellous ; petals ;| in. long; stamens 

 about 20 2. A. triloba. 



1. A, cordata, B. Br. ex Steud. Nomencl. ed. 2, i. 49. A tree up to

 at the base; when lobed with a solitary large more or less stipitate 

 globose gland at the base of each sinus, chartaceous or submembranous, 

 digitately 5-nerved from the base, adpressed-pubescent with simple hairs 

 when very young, soon becoming glabrous except for the tufts of hairs in 

 the axils of the principal and secondary nerves below ; transverse nerves 

 parallel ; petiole 1 J-8 in. long, terete, glabrous ; stipules early deciduous.
