Scroph^dar^ne<z. 3 5 * 



and toothed. Scapes bracteolate, bearing numerous drooping 

 tubular scarlet flowers. A native of the Andes. 



Besides the above enumerated plants of this order there is a 

 large tribe of very handsome plants still almost unknown in 

 cultivation, on account of the difficulties experienced in raising 

 them artificially, due to the fact that they are mostly partially 

 parasitical in the natural state on the roots of the plants they 

 are associated with. This section includes amongst others the 

 genera Gerdrdia, Pedicularis, Melampi/rum, and CastiUeja. 



ORDER LXXIX.-BIGNONIACE.ffi. 



Handsome shrubs or herbs of trailing, twining or climbing 

 habit, or more rarely erect. Leaves usually opposite, compound 

 or simple, exstipulate. Calyx inferior, entire or lobed or 

 spathaceous. Corolla regular or irregular. Stamens 5, of which 

 4 or only 2 are fertile. Fruit a dry frequently woody capsule, 

 2-celled with a central placentation, or 1 -celled with parietal 

 placentation. Seeds compressed, winged, destitute of albumen. 

 There are about fifty genera, comprising 450 species, for the 

 greater part inhabitants of tropical regions. 



1. BIGNONIA. 



Shrubby climbers with pinnate deciduous often tendrilled 

 leaves and handsome campanulate flowers. Calyx entire or 

 obscurely toothed. Corolla slightly irregular. Fertile stamens 

 4, with a rudiment of a fifth. Capsule 2-celled, 2-valved, 

 compressed, the partition parallel with the valves. This genus 

 commemorates the Abbe Bignon, librarian to Louis XIV. 



1. B. capreolata. A very handsome glabrous climber with 

 unijugate leaves terminating in a branched tendril, and often 

 provided with two very small leaflets near the base of the 

 petiole. Peduncles clustered, one-flowered. Flowers large, 

 orange. A native of North America from Virginia southwards, 

 and only suitable for warm sheltered situations. 



2. TEC5MA. 



This differs from Bignonia in the convex valves of the capsule 

 being contrary to the partition, and in the leaves being desti- 

 tute of a tendril. The name is an abbreviation of the Aztec 

 Tecomaxocbitl.
