355 SYNOPSIS OF THE BUCHNERE.E, 
vulis integris bifidisve, rarissime carnosa 
indehiscens. To this might be added, 
Stylus apice integer, stigmate simplici ; 
which appears to be universal in the 
tribe. 
With this character the genera Erinus, 
(as confined to E. alpinus,) Sutera, and 
Sophronanthe, which I have en 
Lindley's Natural System as belonging to 
Buchneree, would be removed to Gratio- 
lee on account of their bilocular parallel- 
celled anthers, and Escobedia, which Don 
includes in his list, would remain in Gerar- 
diee, where I placed it in my Synopsis of 
that tribe, p. 202 of this ** Companion." 
The Buchneree thus circumscribed are 
readily divisible into two very distinct 
groups: the Hubuchneree, in which the 
valves of the capsule are entire, with a 
loculicidal dehiscence, and the Manulee, 
in which they are more or less bifid and 
septicidal. The former contain a set of 
_ plants which are usually rigid, more or less 
scabrous, and almost always dry black; 
the Manulee, if hairy, are generally glu- 
tinous, seldom scabrous, and comparatively 
few of them dry black. 
The Eubuchneree consist chiefly of the 
genus Buchnera as limited by Brown, 
but whose sections I should propose to 
adopt as genera, the difference in the struc- 
ture of the corolla being connected with a 
considerable difference in habit. It is for 
the first of these sections, containing the 
species with straight-tubed hypocrateriform 
corollas, that I should propose to retain 
the Linnean name in preference to that of 
Piripea, given by Aublet to one of the 
species, as the plants of this section are 
perhaps the most universally known, and 
being the most numerous, there would thus 
be the fewest published names to change. 
Amongst the species contained in Mr. 
Brown’s second section, having anincurved 
tube with a bilabiate limb, is the plant 
published by Dupetit-Thouars, under the 
name of Campuleia, and Mr. Brown has 
ascertained that another species (probably 
B. hirsuta, Wall.) is the Striga of Lou- 
reiro, which that author erronecusly de- 
scribed as diandrous, with an unilocular 
nmeratecd in

capsule. The latter name being the oldest, 
is the one I have adopted. 
Buchnera, thus limited, would contain, ; 
besides the several Australian species of 
Brown's first section, and the East Indian 
ones of the section Pirzpea enumerated in 
ndicæ allthe American 
aily t 
Buchneras and five species now first de- 
scribed. Striga would include Brown's 
two Australian species, the East Indian 
species of the section Campuleia of my 
Scrophularinez Indice, the two species of 
Thonning’s described by Schumacher, and 
three new ones. 
To these genera I have to add two new 
ones, Rhamphicarpa, distinguished chiefly 
by the oblique capsule, containing the Ge- 
rardia tubulosa, Linn., and two unpublish- . 
ed species ; and Cycnium, a MSS. name of | 
Mr. E. Meyer’s, under which I have joined —— — 
two South African plants intermediate in 
some respects between the Buchnere@ and 
the Gerardieg. In the one, C. adonense, 
the capsule appears to be fleshy and inde- 
hiscent, the flower is that of an Escobedia, 
but unfortunately in all the specimens I 
ossess, the stamina are eaten away by m- 
sects; the other, C. racemosum, has a much 
shorter-tubed corolla, and the capsule is 
not yet formed in the specimens before 
me, but the stamina are perfect and pre- 
cisely those of the Buchneree; and the 
remarkable calyx in both species has m- 
duced me to join them, taking the generic 
character from the one or the other accord- 
ing as I have been able to examine them. 
If I am wrong, it will be for future Bo- 
tanists to correct my error from more per- 
fect specimens. 
The group of Manulee, which are all 
South African, has been usually considered 
as containing two genera: the Cape Erim 
or Nycterinia, with bifid lobes to the 0 
rolla, and Manulea, with entire lobes, & — 
distinction which however is not practically a 
followed up, for the Erinus fragrans, Ait, 
and Æ. tristis, Thunb., have the lobes e€— 
tire, or nearly so, nor is it at all conform- 
able to habit; besides, there are so many 
species in which the lobes are so slightly 
emarginate as to render it impossible
