Tweediana ; foliis conjugatis, foliolis lanceolatis acuminatis apice subaris- 

 tatis petiolis leviter pubesceutibus, peduncnlis uniiioris flore brevioribus, 

 calyce bilabiato oblique truncate sub 5-lobo labiis utrisque rotundatis 

 supremo majore, corolise glaberrimse limbo alt^ 5-partito ciliato : laciniis 

 rotundatis emarginatisque tubo gracili duplo brevioribus. 



For this new Bignonia we are indebted to the Hon. W. F. 

 Strangways, by whom it was imported from Buenos Ayres in 



1838. 



It is very nearly allied to B, cBquinoctialis, from which it 

 differs in having much narrower leaflets, a distinctly lobed 

 2-lipped calyx, and a more slender flower whose lobes are 

 deeply divided, and narrower at the base than at the apex. 



The name of B. cequinoctialis does not occur among the 

 species enumerated by M. DeCandolle in his Revue de la 

 famille des Bignoniacees, but we presume it must be retained 

 by him in the genus Bignonia proper, of which it appears that 

 200 species are known to that learned Botanist. Considering 

 their uniform beauty it is surprising that we should not find 

 them commonly cultivated, and that out of so large a number, 

 inhabiting parts of the tropics constantly visited by Euro- 

 peans, scarcely any collection can boast of a dozen species. 



This is a greenhouse plant of the most easy cultivation, 

 striking readily from layers or cuttings, and growing freely 

 from seeds when they can be procured. It will succeed in 

 almost any soil, but prefers a mixture of loam, peat, and sand, 

 thriving best and seen to the greatest advantage if planted
