A426 APPENDIX. No. V. 
One of these is Banisteria Leona, first described, from Smeathman’s speci- 
mens, by Cavanilles,* who has added the fruit of a very different plant to his 
figure, and quotes the herbarium of M. de Jussieu as authority for this species 
being likewise a native of America, which is, I believe, equally a mistake. 
The two remaining plants of Malpighiacez, in the collection, with some 
additional species from different parts of the coast, form a new genus, having 
the fruit of Banisteria, but with sufficient distinguishing characters in the 
parts of the flower, and remarkable in having alternate leaves. From this 
disposition of leaves, in which the genus here noticed differs from all others 
decidedly belonging to the order, an additional argument is afforded, for 
referring Vitmannia to Malpighiacez; as proposed by M. du Petit Thouars ;+ 
and the approximation, though perhaps not the absolute union of Erythroxylon 
to the same family is confirmed. 
It may not be improper here to notice a very remarkable deviation from the 
usual structure of leaves m Malpighiacez, which is supposed to occur in a 
plant of equinoctial Africa, namely Flabellaria pinnata of Cavanilles (the 
Hiraa pinnata of Willdenow.) It is certain, however, that the figure given by 
Cavanilles of this species is made up from two very different genera; the pin- 
nated leaf belonging to an unpublished Péerocarpus ; the fructification to a 
species of Hiraa, having simple opposite leaves. ‘The evidence respecting 
this blunder, which was detected by Mr. Dryander, is to be found in the 
herbarium of Sir Joseph Banks. 
In Malpighiaceze the insertion of the ovulum is towards its apex, or consi- 
derably above its middle ; and the radicle of the embryo is uniformly superior. 
In these points Banisteria presents no exception to the general structure, 
though Gertner has described its radicle as inferior, and M. de Jussieu does 
not appear to have satisfied himself respecting the fact.; It appears, how- 
ever, that M. Richard is aware of the constancy in the direction of the embryo 
in this order.§ 
HIPPOCRATICE. M. de Jussieu has lately proposed this as a distinct 
family,|| of which there are two plants in the collection. The first is a species 
of Hippocratea ; the second is referable to Salacia.
