Order LIX. BIGNONIACE-E. 



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-celled, rarely 1-celled, 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 all a dehiscent capsule, the 2 valves separating from the dis- 

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

 Wight 111. ii. 182 ; E. Bureau, Monographie des Bignoniacees (premiere 

 partie), Paris, 1864. 



Capsule flat, dehiscing septicidally, the dissepiment parallel 

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

 leaves bipinnate, opposite. 

 Corolla campanulate ; stamens 5, inserted above the base ; 



anthers 2-celled 1. Calosanthes. 



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



the long cylindric tube ; anthers 1-celled . . .2. Millingtonia. 

 Capsule flat convex or cylindrical, dehiscing loculicidally, the 

 dissepiment transverse to the valves, and attached to their 

 median line before dehiscence. 

 Seeds with long, bilateral wings ; leaves pinnate or bipin- 

 nate. 

 Dissepiment continuous, cylindrical flat or (on a horizon- 

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

 Dissepiment jointed, cylindrical ; nucleus of seeds wedge- 

 shaped, embryo doubled up 4. Stereospermum. 



Seeds winged on three sides ; leaves simple (digitate in extra 



Indian species) 5. Tecoma.
