Sinnlngia (or Gi-oxfNiA) specibsa, Nicholson. The GLOXINIA of green- 

 houses ; an almost stemless herb from Brazil, with ovate and crenately 

 toothed leaves and 1-flowered scape-like peduncles ; the deflexed corolla 2' 

 long, ventricose, between bell-shaped and funnel-form, gibbous, with a

Ncegelia (or GESN^RA) zebrina, Regel. Stem tall, leafy ; leaves peti- 

 oled, cordate, velvety, purple-mottled ; a terminal raceme of showy 

 flowers nodding on erect pedicels ; corolla tubular-ventricose, with a 

 small 5-lobed and somewhat 2-lipped border, glandular, scarlet, with the 

 under side and inside yellow and dark-spotted. There are several other 

 species. # Brazil. 



Achimenes longiflbra, DC. Stem leafy ; flowers in the axils of oblong 

 or ovate hairy leaves, which they exceed ; tube of the obliquely salver- 

 shaped corolla over an inch long, narrow, the very flat 5-lobed limb 2' or 

 more broad, violet-colored above, also a white variety. Propagates by 

 scaly bulblets from the root. 2/ Central America. 



Streptocdrpus Hexii, Lindl. A stemless greenhouse plant from South 

 Africa, with ovate-oblong, crenate, and wrinkled, pubescent, prostrate 

 leaves, and blue flowers on a 2-bracted 1-2-flowered scape ; calyx 5- 

 parted ; corolla limb oblique and bilabiate, the upper lip 2-lobed and the 

 lower 3-lobed ; 2 perfect stamens ; ovary imperfectly 4-celled and 2-lobed. 



S. pofydntha, Hook. Has many flowers, white with purplish streaks, 

 in a sort of loos panicle. Other species and hybrids are in cultivation. 



LXXXV. BIGNONIACRfi, BIGNONIA FAMILY. 



Woody plants, or a few herbs, with more or less 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 filled with the large em- 

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

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



* Climbers (except one Tecoma), with compound leaves and 4 fertile stamens in two 



pairs. 

 - Barely woody or herbaceous; ovary and pod l-celled with 2 parietal placenta. 



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



recurred lobes. Pod short. Seeds winged all round. 



+. +. Woody-stemmed ; ovary and pod 2-celled, but the placentce parietal ; valves of 

 pod falling away from the partition ; seeds with a broad thin wing. 



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



parallel with the valves and partition. Climbing by leaf-tendrils. 

 8. TECOMA. Calyx 5-toothed. Corolla funnel-shaped, tubular, or bell-shaped, 5-lobed. 



Pod flattish or flattened contrary to the partition, the edges of which separate from 



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



rootlets. 



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

 4. CATALPA. Calyx deeply 2-lipped. Corolla inflated bell-shaped, the 5-lobed border 



more or less 2-lipped and wavy. Pod very long and slender, hanging, the partition 



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



stamens, see Lessons, Fig. 265.)
