102. BIGNONIACE.E. [4. Tecoma. 



sometimes veined with a deeper colour, 2-2"5" long and 1-2" wide, 

 tube white inside. 



Freciuent in gardens. Native of Guiana. Fl. h.s. 



Leaflets attain 6-7" in lower part of stem, ovate-lanceolate and often ternate. 

 Calyx sub-truncate. Disc inconspicuous. I)e Candolle says that it diifers from 

 B. (sqiiinoctialis by the 4-gonous branches. 



7. B. Chamberlaynii, Sims. Treated as synonymous with B. cequinoc- 



tialis at the Ag-ri-Horticultural Society's Gardens, Calcutta 

 (probabl}'' following- Firminger). 

 A glabrous scandent shrub with terete branches. Differs from the 

 ordinary cequinoctialis by the primrose-coloured floAvers and more 

 distinctly 5-toothed calyx. 

 Native of Brazil. 



Firminger says — " From the axils of the leaves are produced primrose-coloured 

 thimble-formed flowers, with the tube 2" long, produced in great profusion nearly 

 at all times." 



8. B. magnifica, Bull in Gard. Chronicle. 



Bull gives merely a figure, uncolovired, and a shoi't description 

 from which it is not possible to determine the genus, and I find no 

 specimens in the Kew Herb. Mr. Sprague tells me that this is not 

 synonymous with Cydista magnijica, Miers. It is a very handsome 

 plant with large panicles of flowers up to S'o" across, delicate mauve 

 changing to rich crimson with throat of a light primrose. 



Native of Columbia, U.S. 



i. TECOMA, Juss. 

 Trees or shrubs often scandent or rooting at the nodes but without 

 tendrils. Leaves opposite simjDle or digitately or pinnately compound, 

 leaflets often toothed. Flowers usually showy, most often yellow, red or 

 orange, racemed or panicled at the ends of the branches or leafy 

 shoots. Calyx tubular-campanulate, sub-equally 5-toothed. Corolla 

 with long straight or incurved tube, slightly widened upwards or 

 much dilated at the throat ; limbs siib-2-lipped with o broad sub- 

 equal spreading or sub-erect lobes. Stamens didynamous, included 

 or exsert, anthers with cells at first often parallel finally divergent or 

 divaricate. Disc annular. Ovules on each placenta 1-many-seriate. 

 Capsule linear or narrowly ellipsoid, usually acute both ends, more or 

 less compi-essed parallel to the septum but loculicidally dehiscent 

 Avith the concave or cymbiform valves transverse to the septum. 

 Seeds at margin of the septum, 1-many seriate, wing at both ends 

 usually broad and membranous. 



Tecoma, like Bignoiiia, is now usually divided into several genera (indicated in 

 brackets in the following Key). Only one species, of the sub-genus Tecomella, ia 

 indigenous. 

 I. Erect trees or shrubs : — 



A. Leaves simple or palmately divided :— 



1. Wing of seed thick, only membranous at margin. Leaves 



simple {Tecomella, Seem.) 1. undulafa. 



2. Wing of seed membranous. Leaves 3-5-nately divided 



(Tecoma proper). All American None 



described. 



Leaves pinnate (rarely reduced to a single leaflet). Anther 

 cells much expanded, often hairy (Stenulobiam, Don) .
