TeIBE 1. BiGNONIEJE. (GrCn. 1-3.) 



1. TECOMA, Juss. 



Calyx bell-shaped, 5-toothed. Corolla-tube short, dilated 

 in the throat, 5-lobed, sub-2-labiate or equal. Stamens 4, 

 didynamous, with rudiment of a fifth ; anthers with divergent 

 cells. Capsules 2-celled, 2-valved, the septum at right angles

T. Capensis, Lnidl., a handsome bush, with ash-like leaves and racemes 

 of scarlet flowers, is cultivated throughout the colony, and found wild, in 

 great profusion, in many parts of the Eastern Province, in Cafii-aria, and at 

 Natal. Its African origin has been questioned by Dr. Seemann, but I 

 think his opinion supported on very slender evidence, and chiefly defensible 

 on abstract theoretical grounds. But why may not there be an African 

 species of Tecoma, — a genus by no means exclusively American, — as well as 

 an African Menodora, or as a Mexican Hermamiia ? 



2. CATOPHRACTES, Don. 



Calyx cleft on one side, on the other 6-toothed. Corolla 

 with a cylindrical tube, funnel-shaped in the throat ; limb 6- 

 lobed, spreading, equal. Stamens 6, rarely 7, subequal, ex- 

 serted ; antlier-cells parallel, free below. Ovary short, conical, 

 2-celled. Fruit unkno^^Tl. — DC. Fro J. ix. p. 233 ; Don in 

 Linn. Trans, xw'iii. p. 30G. t. 22.
