174 . NATURAL HISTORY OF PLANTS. 
flowers in simple, lateral or terminal racemes ; bracts and bractlets 
rarely persistent (Zropical America, Africa, and Asia, Indian Archi- 
pelago). See p. 98. 
34, Baikizea Benta.—Flowers subregular; receptacle turbinate, 
lined by a disk. Sepals 4, thick, velvety without; edges abruptly 
tapering or obliquely bevelled, imbricated; highest sepal broader 
(double). Petals 5, subequal unguiculate imbricated; highest petal 
innermost equilateral, remainder oblique. Stamens 10, free; fila- 
ments villous at base, thinner in 5 alternisepalous stamens; anthers 
introrse 2-rimose, versatile. Germen excentric stipitate o-ovulate ; 
apex tapering into a glabrous, minutely capitate, style. Fruit ...? 
—Trees, glabrous except the flowers; leaves paripinnate, 1—2-jugate 
large coriaceous ; stipules minute ; flowers large, in short subterminal 
racemes; bracts and bractlets short caducous (Western Tropical 
Africa). See p. 98. 
35. Tamarindus T.—F lowers irregular; receptacle narrow tubu- 
lar, lined by a disk. Sepals 4, imbricated; highest sepal broader 
(double). Petals 3, posterior imbricated; highest petal innermost 
or more rarely outermost, often narrower. Stamens 9 (of Hetero- 
stemon) ; 8 fertile larger, superposed to inferior petals; filaments 
connate to form a sheath cleft above, becoming free at middle, 
anthers introrse 2-rimose ; 6 sterile reduced to short subulate stami- 
nodes. Germen stipitate, very excentric, inserted posteriorly on 
margin of receptacle, oo-ovulate; apex of style scarcely dilated, 
truncated stigmatiferous. Fruit oblong or linear, subcompressed 
curved drupaceous indehiscent; epicarp crustaceous fragile; meso- 
carp thick, very pulpy, traversed by woody branched veins; endo- 
carp coriaceous, septate between seeds. Seed obovate-orbicular, 
compressed; testa very hard; embryo exalbuminous; cotyledons 
fleshy ; radicle straight included.—An unarmed tree; leaves alter- 
nate paripinnate, leaflets small o-jugate; stipules lateral caducous ; 
flowers in racemes at extremities of branches; bracts and bractlets 
coloured caducous (Zropical Africa (and Asia ?)). See p. 99. 
36. Vouapa Avsi.—Flowers irregular; receptacle concave, of 
variable form, sometimes narrow tubular, oftener shortly turbinate, 
lined by a disk. Sepals 4; highest sepal broader; more rarely 5
