99. Bignoniaceae. 
Flowers hermaphrodite, usually more or less irregular. Calyx 
inferior, gamosepalous, truncate, lobed or spathaceous. Corolla gamo- 
petalous; tube campanulate, funnel-shaped or tubular, often pilose at 
the insertion of the stamens; limb bilabiate, the 2-lobed posticous 
lip usually overlapping the 3-lobed anticous lip in bud, more rarely 
regular. Stamens inserted on the corolla-tube, 4, didynamous, with 
a posticous staminode, or 5, equal, very rarely 2; filaments filiform 
or flattened, often thickened at the base; anthers introrse, dehiscing 
longitudinally; lobes attached at the apex, parallel, divergent or 
divaricate. Disk hypogynous, cushion-shaped, annular or cupular, 
rarely absent. Ovary 2-celled or, more rarely, 1-celled with 2 
parietal, often much intruded placentas; ovules numerous, anatro- 
pous; style simple, filiform; stigma of 2 flattened lobes. Fruit a 
2-valved loculicidal or septifragal capsule, or fleshy and indehiscent. 
Seeds usually flat with a broad, often hyaline wing; embryo usually 
enveloped in a fine interior membrane (tegmen); albumen none; 
cotyledons flattened, rarely folded; radicle short, lateral (very rarely 
superior). —- Trees or shrubs, frequently twiners or climbers, very 
rarely herbs. Leaves opposite, more rarely whorled or alternate, 
usually compound with articulated leaflets, often cirrhiferous; stipules 
absent, but closely simulated in certain genera by the first or first 
aud second pairs of leaves of the axillary bud (pseudostipules). 
Inflorescence a panicle or raceme (simple or with cymose ultimate 
branching), terminal or axillary; flowers sometimes borne on the old 
wood, often large, abundant and brightly coloured. 
Genera about 105, many of them monotypic; species about 550, mostly

in pairs, included in the tube; anther cells diverging or divaricate.
