B. Tweediana ; foliis conjugatis, foliolis lanceolatis acuminatis apice subaris- 
tatis petiolis leviter pubescentibus, pedunculis unifloris flore brevioribus, 
calyce bilabiato oblique truncato sub 5-lobo labiis utrisque rotundatis 
supremo majore, corollz glaberrimze limbo alté 5-partito ciliato : laciniis 
rotundatis emarginatisque tubo gracili dupló 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. equinoctialis, 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. equinoctialis does not occur among the 
species enumerated by M. DeCandolle in his Revue de la 
famille des Bignoniacées, 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
