APPENDIX. No. V. 441 
Five species belonging to this section of Violeae occur in Aublet’s History 
of the Plants of Guiana, where each of them is considered as forming a sepa- 
rate genus. Of three of these genera, namely, Conohoria, Rinorea, and 
Riana, the flowers alone are described; the two others, Passwa and Piparea, 
were seen in fruit only. 
From the examination of flowers of Aublet’s original specimens of the 
three former genera, in Sir Joseph Banks’s herbarium, and of the fruit of 
Conohoria, which entirely agrees with that of Passwra, and essentially with 
that of Piparea, I have hardly a doubt of these five plants, notwithstanding 
some differences in the disposition of their leaves, actually belonging to one 
and the same genus: and as they agree with Physiphora im every respect, 
except in the texture and form of the capsule, and with the Passalia of Sierra 
Leone and Congo, except in haying their stamina nearly or entirely distinct, 
it appears that all these genera may be referred to Alsodeia. 
T have also examined, in Sir Joseph Banks’s herbarium, a specimen of Pen- 
taloba sessilis of the Flora Cochinchinensis, which was sent so named, by 
Loureiro himself, and have found it to agree in every important point with 
Alsodeia, even as to the number of parietal placentae. Loureiro, however, 
describes the fruit of Pentaloba as a five-lobed, five-seeded berry, and if 
this account be correct, the genus ought to be considered as distinct ; but if, 
which is not very improbable, the fruit be really capsular, it is evidently 
referable to Alsodeia; with the species of which, from Madagascar and the 
west coast of equinoctial Africa, 1t agrees in the manifest union of ifs filaments. 
It appears therefore that the ten genera now enumerated, and perhaps also 
Lauradia of Vandelli, may very properly be reduced to one; and they all at 
least manifestly belong to the same section of Violes, though at present they 
are to be found in various, and some rather distant, natural orders. 
M. de Jussieu, in adopting Aublet’s erroneous description of the stamina of 
Rinorea and Conohoria, has referred both these genera to Berberides,* to which 
* The genera belonging to Berseripem are Berberis (to which Ilex Japonica of 
Thunberg belongs); ZLeontice (including Caulophyllum, respecting which see Linn. Soc, 
Transac. 12, p. 145) Epimedium; and Diphylleia of Michaux. Jeffersonia may perhaps 
differ in the internal structure of its seeds, as its does in their arillus, from true Berberi- 
dew, but it agrees with them in the three principal characters of their flower, namely, in 
their stamina being equal in number and opposite to the petals; in the remarkable 
dehiscence of anthere; and in the structure of the ovarium. Podophyilum agrees with
