3329 Mr. Roscor’s New Arrangement of the Plants of the 
plants; a discovery which, however, he has not sufficiently pro- 
secuted, either in the work before referred to, or in his subse- 
quent attempt, in his sixth fasciculus, to establish ti new Ls of 
these plants. l ECAN Bn ! e 
Since the publications of Retzius, some additions and correc- 
tions of the genera and species have been made by Swartz, in 
his Observationes Botanice; but without any attempt at a syste- 
matic order. He concludes. his remarks with asserting that 
* the genera of the Scitaminean plants are so — that 
they can scarcely be distinguished by characters *." — : 
If we turn from Linneus and his followers to those ilio; pro- 
fess to have arranged the individuals of the vegetable kingdom 
by their natural affinities, | we shall discover little further light 
thrown on the subject. "The Scitaminean plants form, indeed, a 
natural order; and Bernard de J ussieu, in his Ordines Naturales, 
has implicitly adopted the arrangement, "without adding to the 
number of the | genera of Linnzus 4. In the Genera Plantarum | 
of A. I 1. de Jussieu, « a few additions : are made to tios: — t 
but the more essential parts o 
generic distinctions chiefly desek nd, aré often arn 'oniitted- in 
bits descriptions. Like the rest who have attempted to charac- 
terize these plants, he remarks—* that the construction of the 
various parts of the flower, has wes a variety of opinions 
as 3 to their denomination and use ; = " and, “that SE observa- 
ee eee genera adeo aia, ut characteribus vix distingui queant,” 2^
