﻿448 BiQNONiACE^ (Sprague). 



longitudinally ; lobes attached at the apex, parallel, divergent or 

 divaricate. Disc hypogynous, cushion-shaped, annular or cupular, 

 rarely ahsent. Ovary 2-celled or more rarely 1-celled with 2 parietal 

 placentas ; ovules numerous, anatropous ; style simple, filiform ; 

 stigma of 2 flattened ovate or oblong lobes. Fruit a 2-valved loculi- 

 cidal or septifragal capsule, or fleshy and indehiscent. Seeds usually 

 flat with a broad often hyaline wing ; embryo usually enveloped in a 

 fine interior membrane {tegmen) ; albumen ; cotyledons flattened, 

 rarely folded ; radicle short, lateral (very rarely superior). 



Trees or shrubs, frequently twiners or climbers, very rarely herbs ; leaves 

 opposite, more rarely whorled or alternate, usually compound with articulated 

 leaflets, often cirrhiferous ; stipules absent, but closely simulated in certain genera 

 by the first or first and second pairs of leaves of the axillary bud {'pseudosii'pules) ; 

 inflorescence a panicle or raceme (simple or with cymose ultimate branching), 

 terminal or axillary ; flowers sometimes borne on the old wood, often large, 

 abundant and brightly coloured. 



DisTRiB. Genera about 105, many of them monotypic ; species about 550, 

 mostly Tropical American.

 at the very apex.

I. TECOMARIA, Spach. 



Cal^x regular, campanulate, 5-toothed, Gorolla-tuhe narrowly 

 funnel-shaped or almost cylindric, curved ; limb markedly bilabiate. 

 Stamens 4, exserted ; anther-lobes connate for the upper third, 

 divergent below. Disc cupular. Ovules 4-seriate in each cell. 

 Capsule oblong-linear, much compressed parallel to the septum. 



Shrubs with simply imparipinnate leaves and dense terminal racemes of orange 

 or scarlet flowers, 



DisTRiB. Species 3, all African. 



The genus Tecomaria has been much confused with StenoloUum, which has free 

 anther-lobes and only two rows of ovules in each coll. Thus Tecomaria, Bur. 

 (Monogr. Bignon. 47) is Stenolobium (vide t. 13); Tecomaria fulra, Seem. = 

 Steyiolohium fulvum, Sprague ; Tecoma Smithii, Btdl, Cat. 1889, 8, a reputed 

 hybrid {T, velutina and T. capensis, Qard. Chron. 1894, ii. 64) = Stenolohium 

 alatum, Sprague (Tecoma alata, DC). 



1. T. capensis (Spach, Hist. Veg. Phan. ix. 137) ; a rambling 

 shrub, about 6 ft. high ; branches subterete, minutely pubescent 

 above, glabrescent below; leaves opposite, short-petioled, 2-5 in.
