5, small dentiform. Germen sessile or shortly stipitate ; cells 5 
oppositipetalous, more rarely 4 or very rarely 2 (Dicarpidium) ; ovules 
2 in each single cell, ascending ; micropyle extrorse, inferior. Cap- 
sule loculicidal, sometimes angular pyramidal (Æwmelochia) ; car- 
pels not at all or scarcely parting, usually subglobose ; carpels some- 
times 2 (Dicarpidium) or oftener 4, 5, easily parted or separating at 
maturity (Riedleia, Mougeotia) ; seeds ascending, sometimes winged 
(Visenia) ; embryo more or less albuminous ; cotyledons flat ; radiele 
inferior. —Herbs, shrubs, or undershrubs, rarely trees; leaves sub- 
ovate or cordate, entire or serrate; stipules usually small or 0; 
flowers lateral and spuriously axillary, connate with the branches 
and elevated on them for a greater or less distance, solitary or cymose, 
sometimes terminal, widely cymose-panicled (P/hysodium, Visenia) ; 
bracts and bractlets small or very small (4// warm regions of the Globe).

Germen sessile 1-carpellary, 1-celled ; ovules 2 ascendent ; micropyle 
extrorse, inferior; style simple, excentric, stigmatiferous at apex, 
clavate, or fimbriate ; capsule 1-spermous dorsally 2-valved; seeds 
ascendent albuminous ; embryo straight (Melochia).—Herbs, under- 
shrubs, or more rarely trees; hairs simple and stellate ; leaves serrate ; 
stipules narrow, flowers in axillary cymes or glomerules ; cymes some- 
times arranged at the summit of the branches in simple or compound 
spikes or racemes (AU the Tropical regions of the Globe). See p. 77. 
VI. BUETTNERIES. 
23. Buettneria Lari.—Flowers hermaphrodite, receptacle con- 
vex. Calyx 5-fid valvate or reduplicate. Petals 5 alternate, clawed 
at base, afterwards in 2-lobed cucullus, apex inflexed and margin 
coalescing inwardly with urceolus of stamens, dilated, upper part 
produced in elongated ligule, entire or 5-fid. Stamens 10, connate 
in urceolus at base ; sterile 5 alternipetalous, thick or subglandu- 
lar, apex attenuate or truncate, fertile 5 oppositipetalous, shortly sti- 
pitate ; anthers articulate at base 2-celled (or more rarely 3) lateral or 
extrorse, longitudinally rimose. Germen superior sessile; cells 5
