1133 
Order XCI. BIGNONIACEjE. 
Flowers irregular. Calyx tubular or campanulate, truncate toothed or laterally 
split. Corolla-tube elongated or rarely short and campanulate ; lobes 5, 
spreading, often arranged in 2 lips, variously imbricate or rarely induplicate- 
valvate in the bud. Stamens 2 or 4, in pairs, inserted in the tube, the fifth 
staminodium usually small, rarely wanting. Anthers 2-ceIled, the cells opening 
longitudinally. Ovary usually 2-celled, with 2 distinct placentas in each cell 
attached to the dissepiments, and either contiguous or separated by a considerable 
interval, or, in some genera not Australian, the dissepiment discontinued between 
the placentas, and the ovary then 1-celled ; ovules several, often numerous to 
each placenta. Style filiform, with 2 short stigmatic lobes. Fruit a capsule, 
often elongated, opening loeulicidally or septifragally in 2 valves, leaving the 
dissepiment free. Seeds transverse, usually flattened and bordered by a 
membranous wing, without albumen. Embryo straight or rarely curved ; 
cotyledons flat or fleshy ; radicle next to hilum. — Trees shrubs or woody climbers, 
very rarely (in species not Australian) herbs. Leaves opposite or rarely scattered, 
compound or rarely simple, without stipules. Flowers solitary in the axils or 
more frequently paniculate. 
An Order almost entirely tropical, and most abundant in South America. 
Tribe I. Tecomeae. — Ovary 2-celled. Capsule loculicidal, 2 -valued.

1. TECOMA, Juss. 
(From the Mexican name Tecoma.rochitl.) 
Oalyx truncate or shortly 5-toothed. Corolla tubular, the lobes spreading, 
nearly equal, obscurely 2-lipped or oblique. Stamens 4, in pairs, included in 
the tube ; anther cells diverging or divaricate. Style with 2 short ovate 
stigmatic lobes. Ovules numerous, in several rows on each placenta. Capsule 
(oblong in the Australian species) opening loeulicidally in 2 very concave valves, 
the dissepiment transverse with relation to the valves, and not laterally dilated. 
Seeds overlaying each other in several rows, flat, broadly winged. — Tall woody 
climbers. Leaves opposite, pinnate. Flowers in terminal panicles. Bracts 
minute ; bracteoles none. 
Species mostly American. The four Australian ones are endemic. 
Panicle corymbose. Corolla about 3in. long, limb reddish, tube pale ... 1. T. Ilillii.

half as long 2. T. australis.

half as long 3. T. jasminoides. 
Leaves attaining the length of 2ft., opposite or in whorls of 3 or 4. Flower

x. 101 and xi. 136. A tall, glabrous climber. Leaves pinnate; leaflets 5, 
ovate-lanceolate, 1 to 3in. long, thin. Corymbs of about 6 flowers. Calyx a to 
lin. long, membranous. Corolla 2 to 3in. long, limb rosy-purplish, the tubes 
pale, marked with purplish lines, the lobes 3 to 4 lines long pubescent towards
