of the fruit, and the number of rows of seeds on each side of 
the dissepiment. . 
Among the more special observations which have occurred 
to us are the following: from Bignonia (which is still a recep- 
tacle for every species that will suit no other genus, and 
consequently remains yet to be defined) it is probable that all 
simple-leaved species will have to be excluded. B. castanee- 
folia is most likely the Tecoma Gaudichaudi, so common 
about Guayaquil. B. obovata is an apocyneous plant. Pa- 
chyptera can scarcely be yet considered as a genus,. being 
established upon two fruits without flower, to which are 
added four species of which the fruits are unknown, no 
generic character being given which can show any reason for 
their being so included. The Delastoma latifolium, described 
by Splitgerber, appears to us to be the same species as 
Tabebuia rufinervis. If the glands on the calyx and general 
habit of Adenocalymna indicate a real genus, it will not be 
confined to South America, an unpublished species having 
been sent from Port Essington, in tropical Australia. The 
digitate-leaved Tecome and Tabebuie are probably congeners, 
and very different from the simple and pinnate-leaved tree 
Tecome. Spathodea is at present an equally heterogeneous an 
assemblage with Bignonia itself. Platycarpum, only known 
from Bonpland’s figure and description, (from which the struc- 
ture of the ovary and seeds is omitted), is evidently no 
Bignoniaceous plant, but must remain a puzzle till it s 
have been examined by a botanist. 
The Sesamee are not at present in a very satisfactory state, 
although so large a portion of the few species enumera 
(twenty-five species in twelve genera) have been the subject 
of detailed descriptions, figures, dissertations or observations 
from botanists of great authority. The true Sesame, in- 
cluding De Candolle's six first genera, and probably also the 
three last, are all bicarpellary, with pluriovulate placentæ, 
and are closely allied to Bignoniacee and Cyrtandreæ, whilst 
Pedalium and Josephinie have long since been shown by 
Brown to bear that analogy only to Sesamum which Myopo-
