Order LIX. BIGNONIACEiE. 



Trees, shrubs or woody climbers. Leaves opposite, rarely alternate, 

 compound, rarely simple, without stipules. Flowers bisexual, often irre- 

 gular. Calyx free, tubular or campanulate, truncate toothed or split, 

 lobes valvate in bud. Corolla tubular or campanulate, often bilabiate, 

 lobes 5 spreading, generally unequal, imbricate, rarely valvate in bud. 

 Stamens 2 or 4, rarely 5, in pairs, in the place of the fifth stamen gene- 

 rally a short staminodium; anthers 2-ceUed, rarely 1-ceUed, the cells 

 opening longitudinally. Ovary free, supported by an annular disc, 2-celled, 

 placentas two distinct in each cell attached to the dissepiment ; ovules 

 numerous ; style filiform, with 2 short stigmatic lobes. Fruit often elon- 

 gated, dehiscent, or indehiscent {Crescentiece). Seeds numerous, usually 

 flat and bordered by a membranous wing, albumen none. The following 

 genera have aU a dehiscent capsule, the 2 valves separating from the dis- 

 sepiment, along the edges of which the seeds are attached. — Eoyle 111. 294 ;

 partie), Paris, 1864. ^ 



Capsule flat, dehiscing septicidally, the dissepiment parallel 

 to the valves, wings surrounding the seed on three sides ;

Corolla funnel-shaped ; stamens 4, inserted at the mouth of 



the long cylindrio tube ; anthers 1-ceUed . . .2. Millingtonia. 

 Capsule flat convex or cylindrical, dehiscing loculicidally, the 

 dissepiment transverse to the valves, and attached to their 

 median line before dehiscence.

 nate.

 tal section) cross-shaped ; seeds flat . . . .3. Spathodea.
