AUTHENTIC CYPERACEE OF LINNEUS. 301 
We have to look down into the synonymy and see what species 
of Kunth or DC. is really meant: it is therefore, I believe, better 
to cite the species in chief as of Kunth or DC. and to place the 
“Linn. emend.” among the synonymy. 
In the reduction of Linneus Sp. Pl., so far as they are repre- 
sented by authenticated specimens, which reductions form the 
substance of the present paper, I have been able to retain all the 
specific names, nearly in their commonly received sense, except 
two, viz. :—(1) Cyperus elegans, Linn., is altogether (i.e. diagnosis, 
picture cited, and specimens) the plant which Rottboell calls 
elegans, and moderns call C. viscosus, Aiton. The plant called 
Cyperus elegans by Swartz and Kunth is a totally different 
species, viz. what we call C. diffusus, Vahl. (2) The name Cyperus 
odoratus, Linn., has been largely employed by botanists: all that 
can be gathered from the diagnosis is that it was a Jarge species ; 
from the figures of Sloane cited, some botanists have imagined it 
to be a species of “ Diclidium” closely allied to Mariscus ferax 
(Cyperus ferax, L. C. Rich.) ; others have supposed it equal to 
Cyperus strigosus, Linn., or one of the species closely allied 
thereto. Linneus has, however, two good specimens on his 
authentically named sheet: one is Pycreus polystachyus, Beauv., 
the other is Cyperus malaccensis, Lam. Upon these data, I call 
Cyperus odoratus, Linn., nomen delendum. 
There has been much dispute of late regarding the citation 
and treatment of the Linnwan genera. The first genus of 
Linneus’s Cyperacee is Schanus, which in the lst edition of the 
Sp. Pl. contains 9 species. These are referred now as follows :— 
2 to Schenus, 1 to Cladium,1 to Cyperus, 1 to Kyllinga, 1 to 
Scirpus, 2 to Rynchospora, 1 to Crypsis (a Grass). 
(In the 2nd edition of the Sp. Pl. three new Scheeni sp. are 
added ; of these 1 is Dulichium, 1 is Tetraria, 1 is Scleria.] 
The modern genus Schenus contains 60 species, mostly 
Australian, and in Benth. et Hook. f. Gen. Pl. vol. ii. p. 1062, 
Bentham cites it as “ Sckenus, Linn., pro parte.” Bentham 
cites it from the 5th edition of the Genera [1767], whereas some 
say he ought to have cited it from the 2nd edition [1742]; that 
makes, no difference whatever. The character of the genus, 
given by Linneus, opens with “ petals 6,” which character cannot, 
in Linneus’s idea of petals, be forced to be true either of any one 
of Linnwus’s 12 species, or any one of the 60 species now in 
Schanus.
