have also adopted as distinct such genera as Disemma (potius Distemma *), Murucuia t, 
Tetrapathæa*, not to mention smaller subdivisions proposed by Bory de St. Vincent or 
Remer. It is not necessary to go into details on these points, the synonymy and refer- 
ences given in the subjoined lists being sufficient for the purpose. 
I retain Astrophea as proposed by De Candolle, but raise it to the rank of a sub- 
genus, and in it I include a small number of species mostly of erect habit (some even 
being trees), destitute of tendrils for the most part, with a many-flowered inflorescence, 
minute bracts, peculiar dilated coronal filaments, an oblong ovary somewhat flattened 
at the top, and from the angles of which proceed the three awl-shaped styles. To the 
species enumerated under this head by De Candolle I have added several which are more 
nearly allied to this group than to any others, though in some instances they differ some- 
what in habit. 
My second subgenus, Plectostemma, is so named from the circumstance that the 
membranous corona, instead of being flat, is almost universally folded into sharp folds, 
and frilled at the edge. Under this subgenus are included, as sections, Tetrapathea, 
Cieca, Dysosmia, Decaloba, Polyanthea, Distemma, to all of which, with the exception of 
Distemma, the same limits, though a lower rank, are assigned as by previous writers. I 
can find no valid reason for keeping up Distemma as distinct, inasmuch as in some cases 
the number of rings is more than two, while in those in which it is confined to that 
number it is not possible to separate the species from those included in Decaloba and 
Polyanthea. One or two of the Australasian species, indeed, have the corona flat, asin _ 
Murucuia ; but these are exceptional cases. | 
The subgenus Murucuia, which was regarded as a genus by Toxpnefort, De Candolle, 
and others, I prefer to retain in Passiflora, and to strengthen it by the transfer of the 
species included by De Candolle under Zacsonia, section Psilanthus. x 
Granadilla forms in every way a well-marked subdivision, whi^ I retain under the E 
same limitations as De Candolle, Bentham and Hooker, and oshe. with the exceptio Je 
that I include in it the species forming the section Tacsonividez of 'e Candolle.

A genus founded by Harvey upon a single species, a native of Nul. I have ada. 
a second species, from Zanzibar, and am inclined to include Peyritsch’s genus Basan- 
anthe under the same heading; but it is perhaps better to wait for further eviüczce t 
before so doing, especially as the validity of Basananthe has been strengthened by the | | 
publication of Dr. Welwitsch, who further calls attention to the likeness of one of the | 
species described by him to a Viola, and of the other to a Sauvagesias. i
