LXXXV. BIGNONIACEiE, BIGXOXIA FAMILY. 



Woody })lants, or a few herbs, with more or h^ss bilabiate 

 flowers, diandrous or didynamous stamens (often with rudi- 

 ments of the wanting ones), 2-lipped stigma, free variously 

 1 -4-celled ovary, and fruit, usually a pod, containing many 

 large, mostly flat and winged seeds fllled with the large em- 

 bryo ; no albumen. Almost all Avoody plants, with opposite 

 leaves, and 1-2-celled pods. (Lessons, Figs. 415, 416.) 



* Climbers (except one Tecoma), with compound leaves and i fertile stamens in two 



pairs. 



+- Barely tvoodi/ or herbaceous ; ovary and pod I celled with 2 parietal placenta. 



1. ECCUKMOCARPUS. Calyx 5-cleft, short. Corolla tubular, with 5 short and round 



recurved lobes. Pod short. Seeds winged all round. 

 •<- ■*- Woody-stemmed ; orary and pod 2-celled, but the plarenirr parietal ; valves of 

 pod falling aioay from the partition ; seeds ivith a broad thin wing. 



2. BIGNONIA. Calyx nearly truncate. Corolla tubular bell-shaped, 5-lobed. Pod llattened 



parallel with the valves and i)artition. Climbinjjr by loaf-tendrils. 

 8. TECOMA. Calyx S-toothed. Corolla funnel-shai)0(l, tubular, or bell-shaped, 5-lobed. 



Pod llattish or flattened contrary to the partition, the cdfres of which separate ft-om 



the middle of the valves. Leaves in ours odd-iiinnate. The hardy species climb by 



rootlets. 



* * Trees, with simple leaves and 2 or rarely 4 fertile stamens. 

 4. CATAI.PA. Calyx deeply 2-lipped. Corolla inllated bell-shaped, the 5-lobed border 



more or less 2-lipped and wavy. Pod very lonjr and slender, han^i^ing', the partition 



contrary to the valves. Narrow wings of the seed lacorate-fringed. (For corolla and
