TABEBUIA (Brazilian name). Bignonidcex. Orna- 

 mental trees grown chiefly for their showy flowers. 



Evergreen: Ivs. opposite, simple or digitate, entire or 

 serrate: fls. in terminal panicles or racemes, rarely soli- 

 tary; calyx irregularly splitting or unequally 3^5-lobed; 

 corolla f unnelform-campanulate ; stamens included; 

 disk annular or cupulate ; ovary with the ovules in many 

 series: caps, more or less com- 

 pressed, usually elongated, 

 glabrous or scaly. About 90 

 species in Trop. and Sub-trop. 

 Cent, and S. A m e r. By 

 Bureau and by Schumann, 

 Tabebuia is limited to the 5 

 or 6 species with simple Ivs., 

 and the species with digitate 

 Ivs. are referred to Tecoma, 

 while the Tecoma of this 

 work is called Stenolobium 

 by these authors. See, also, 

 Bignonia. 



The tabebuias are upright 

 trees with large evergreen 

 foliage simple or digitate and 

 with large pink, white, or yel- 

 low flowers in terminal, usu- 

 ally few-flowered panicles or 

 racemes or sometimes soli- 

 tary. They are suited for 

 cultivation in tropical or sub- 

 tropical countries only and 

 are sometimes grown in 

 southern California and Flor- 

 ida. They grow luxuriantly 

 in rich or well-manured soil 

 and are easily propagated by 

 cuttings and also by air-lay- 

 ering.
