196 Dr. B. Seemann on the Bignoniacese. 
pee and Pleostictides. The authentic specimens in Berlin leave 
no doubt on this point. It is a climber, the only Catalpea 
having tendrils! 1 do not consider Bignonia glutinosa a con- 
gener of it. That species is an erect shrub, and has a different 
calyx and corolla. Mr. Miers is quite right in referring Delostoma 
to Catalpex. After the publication of the fine plate of Codazzia 
speciosa, Karst. et Trian. (identified by me in 1859 with Delo- 
stoma integrifolium, Don), no one could doubt it. <Astianthus 
ought also to be transferred to Catalpeze, and placed near Chi- 
lopsis ; Cybistax (Yangua Spruce, Spathodea? fraxinifolia H.B.K.) 
must share the same fate. Tabebuia I would not wish to keep 
up; most species enumerated under it by DeCandolle belong 
to Tecoma (which I restrict to the arboreous, digitate-leaved, 
monostictideous species), and the others to Callichlamys, Bigno- 
nia, and Anemopegma*.,  Dipterosperma, Hassk., I class with 
Stereospermum (D. personatum= St. Hasskarli, Zoll.). Several 
foreign elements I expel from the order altogether, viz. :— 
Bignonia? obovata, Hook. et Arn. = Stemmadenia pubescens, 
Benth., aun Apocynea. 
B. Peruviana, Linn. = Vitis bipinnata, Torr. et Gray, an Apeli- 
dea, according to an authentic specimen in the British Museum. 
B. comosa, Roxb., may prove identical with Paulownia impe- 
rialis, or rather P. tomentosa, Ascherson (B. tomentosa, Thunb.), 
a Scrophularinea. 
Bravasia floribunda, DC. = Onychacanthus Cumingianus, Nees, 
an Acanthacea. 
Spathodea ilicifolia, Scem.= Digitalis dracecephaloides, Arvab. 
FI. Flum. vi. t. 101, an Acanthacea, but quite a new genus. 
Tourretia lappacea, Willd., I would place amongst Sesamez, 
near Sesamopteris, as Mr. Miers has already suggested. 
For the present I shall content myself with these observations, 
necessarily forced upon me by what had been written after the 
publication of my ‘Synopsis Crescentiacearum.’ But as the 
public would not be in a fair position to judge of the merits of 
the case unless Mr. Miers’s objections to the above were made 
known, I submitted the whole of the preceding matter to Mr. 
Miers; and the letter which he wrote to me after receiving it, 
and has kindly permitted to appear in these pages, will conclude 
all I have to offer :— 
* Tabebuia uliginosa, T.? leucoryla, T. cassinoides, T, hemantha, T. 
triphylla, T. fluviatilis, and T. rosea, belong to Tecoma.  T. ilicifolia is 
identical with Bignonia anastomasans, and probably the type of a new 
genus peculiar to Madagascar; T. latifolia and T.? rufinervis belong to 
Callichlamys; T. citrifolia seems to be a species of Anemopegma; T. py- 
ramidata is = Zeyhera surinamensis, Miq. (Bignonia pyramidata, Rich., 
B. rupestris, Gardn., B. Sinclairi, Bth., and a host of others).
