REVISION OF THE NATURAL ORDER BIGNONIACE E. 
By BERTHOLD Seemann, Pu.D., F.L.S, 
(Pirate IX.) 
DOLICHANDRA, Cham. 
This genus, established by Chamisso in 1832, is the only Ca/alpea 
which climbs by means of tendrils, all other Catalpee being either trees 
or erect, winding, or rooting shrubs. De Candolle referred it, with a 
mark of doubt, to Spathodea, but with that genus, as now restricted, 
Dolichandra has nothing in common except tribal characters, the spa- 
thaceous calyx and the arrangement of the seeds in several rows. There 
is at. present only one species known, D. cynanchoides, discovered by 
Sellow in Brazil, and the authentic specimens of which with fruit at- 
tached !), preserved at the Royal Herbarium at Berlin, have been obli- 
gingly transmitted to me by the permission of his Excellency the Prus- 
sian Minister of Public Instruction, and have furnished the material 
for our plate, the only one as yet published of the genus. Bignonia 
glutinosa, De Cand., referred as a second species to Dolichandra by Mr. 
Miers* previously to the true type of the genus being known in this 
country, must be excluded.
