The same kind of diversity of structure also t)])tains in 
PedalinaB as proposed to be limited at fol. 934. In that 
order, at least in Martynia Zanquebarica, which is either 
a species of Josephiiiia, or a nearly related genus, the two 
opposite placentas meet in the centre, where they form a 
cohesion, but being 2-lobed, and their lobes rerolute, a 
cohesion is again formed with the sides of the cnd()car])ium, 
where the edges of the lobes touch it ; whence the cap- 
sule is 6-celled, the two anterior and posterior empty cells 
being- formed by the space occasioned l)y tlie diveriifence 
in opposite directions of the lobes of the placenta, and the 
4 lateral seminiferous cells owing their existence to the 
accretion of the lobes of the placenta to the sides of the 
ovarium. Now, in Martynia, there^being no folding back 
of the lobes of the placenta, which, on the contrary, are at 
right angles with their centre, and no cohesion taking place 
between the placentas themselves or their edges and the 
sides of the ovarium, the necessary consequence is, that 
the pericarpium is unilocular, with spurious cells ; whence 
it rqay be predicated that Martynia bears the isame rela- 
iioA Fedalipa? ai^ Eccremocarpus to Big^pniaceaB. 
Perhaps Eccremocarpus may most properly be con- 
sidered the connecting link between Bignoniaceae and 
Gesnerieae, agreeing with the latter in their unilocular 
ovarium, glandular pubescence, and some other peculiari- 
ties of appearance, and with the former in their moi e 
essential attributes. Cyrtandraceae of Dr. Jack, which 
certainly have a 2-celled capsule as described by that 
lamented Botanist, and not a 4 -celled one as erroneously 
stated by the author of some remarks upon Didymocarpeae 
(which are the same order under another denomination), 
difl'er from Bignoniaceae only in their apterous seeds and 
simple stigma, and from Gesnerieae in their bilocular cap- 
sule, and the absence of albumen, agreeing with the latter 
altogether in habit ; they may therefore be considered to 
have on the part of Gesnerieae nearly the same relation 
to Bignoniaceae, as Eccremocarpus on the part of the 
latter bears to Gesnerieae.
