LIV. RHIZOPHORACEE (OLIVER). 407 
Anisophyllea); stigma simple or lobed. Fruit coriaceous, 1-celled, 
l1-seeded, indehiscent, or 3—4-celled with 1-2 seeds in each cell, and 
septicidally dehiscent. Seed albuminous or exalbuminous, in the latter 
the cotyledons minute ; in Rhizophoree germinating in the still attached 
fruit, the apex of which is perforated by the elongating pendulous 
radicle-—Trees or shrubs mostly affecting littoral situations ; usually 
glabrous. Leaves opposite, stipulate (alternate, exstipulate in Aniso- 
phyllea). Flowers axillary, solitary, cymose or glomerate, sessile or 
pedicellate, with or without sheathing bracteoles at base. 
A rather small Tropical Order, common to the shores of both hemispheres. Two 
genera are peculiar to Africa and its Islands ; one of these to Madagascar. 
Leaves opposite, stipulate. Ovary inferior or §-inferior. Style 1.

Flowers very coriaceous. Calyx-tube very short, sheathed by con- 
fluent bracts, limb 4-partite, lobes lanceolate or oblong coriaceous val 
vate. Petals 4, entire, margins not meeting in bud. Stamens 8 (-12), 
perigynous ; filaments very short or 0; anthers erect, elongate, trian- 
gular in section, 2 inner faces multilocellate, pollen liberated by separa- 
tion of a common indusium. Ovary inferior or nearly so, 2-celled; 
ovules geminate pendulous; style more or less thickened below, 2-den- 
tate at stigmatic apex. Fruit coriaceous, ovoid or obconic, 1-celled, 
l-seeded. Seed exalbuminous ; cotyledons conferruminate ; germina- 
tion taking place in the fruit, the radicle at length much exserted 
(1 ft. or more), terete or nearly so, at length rooting in the mud.— 
Trees; extremities stout, marked with annular scars. Leaves oppo- 
Site, petiolate, entire, very coriaceous, glabrous. Stipules interpetiolar, 
elongate, caducous. Cymes axillary, pedunculate, 2—3-chotomous,
