_ the i Befods us, is omental Ais justified in citing “« P [luchea] 
Sdsodash Oliv. Fl. Trop. Afr., iii., 272;” «O. & H.” (Oli ~ heey

that the name is duly published by Mr. Clarke, who is therefore 
the authority for it, in his ‘ Composite Indice.” 
The bulk of the present part is occupied by the Composite, 
which have been elaborated by Sir Joseph Hooker, who has mainly 
followed upon the lines laid down in Mr. Clarke’s ‘ Composite 
Indice,” noticed in this Journal for 1876 (pp. 317, 318). We note 
in passing that our suspicions there ex ressed as to the ete: 
are confirmed by Sir Joseph Hooker, vies states that Mr. Clave

Mr. Hemsley has commenced the second volume of his hand- 
some work on Central American ters and we congratulate him 
upon the steady dieigans which he is making. In last year’s 
‘ Journal of Botany,’ pp. 88-91, we oritivised the beginning of the 
work at some length; and the present instalment of it shows that 
Mr. Hemsley may at ‘hak claim the merit of consistency, inasmuch 
as our criticisms of Parts I. and II. apply with equal force to the 
sn now before us. We notice, however, that the references to 
any herbarium except that of Kew have entirely ceased; so that 
it becomes a question whether the work can claim to be more than 
a catalogue, with descriptions of some of the new species, of the 
Central aren plants in the Kew collection—supplemented indeed 
by references to species described in books from that region, but with 
no attempt at asic raat so far as the examination of other large © 
erbaria is concerne abstain from sty Hee: what we have 
already said at some incgeie oe this point; but we fail to under- 
stand why a large collection of ‘Moxienn plants, so o readily accessible 
as that of Ruiz and Pavon in the National Herbarium at South 
Kensington, should be altogether passed over. Had that Herbarium 
been consulted in the most cursory way, the types of two species 
ba cicero ie Nicaragua—named by Dr. Seemann P. cyano- 
and P. chontalensis, and published by | him in Mr. W. Bull's 
‘ Retail Cuilogn for 1870—would have received some mention ; 
he former appears to be a very distinct afieeteas and was figured in 
the ‘ Floral vf eect (t. 479). J. Bs
