3802 - MR. C. B. CLARKE ON CERTAIN 
It is frequently said that Linneus’s genera are our Suborders 
or Tribes, and that when we make a Tribe of 6 or 8 genera out 
of one of Linneus’s genera it is well to apply the Linnean name 
to the largest or most characteristic genus, pro parte. But 
nothing of the kind can be said here; Linneus’s eleven Schent 
sp. are taken at haphazard throughout the Order (the grass being 
thrown in) from the most remote and unlike genera. To call the 
present genus “ Schaenus, Linn.,” in any sense, or even “ pro 
parva parte,” is wholly complimentary. 
When I have brought these things to the notice of some 
experienced botanists, they have attempted to evade any general 
conclusions thence as to how the genera and species of Linneus 
are to be treated by observing that the Cyperacee are unlike 
other orders, and that Linneus’s treatment of other orders will 
be found different. I have tried several other orders, and it 
appears to me that Linneus worked in just the same way through- 
out: he took the diagnoses of his predecessors, he identified the 
pictures very boldly, he made his diagnosis include somehow his 
type specimens. 
Here follows a reduction of all the Cyperacez (except Carex) 
now in the Linnean Herbarium, which have their names written 
on the sheets in the hand of Linneus. 
Where we still keep the species (whole or part) in the same 
genus in which Linneus placed it, I have further considered in 
what form the citation of it should be made. Where the species 
is now to be placed under some genus later than Linneus, it is 
not requisite to expend thought or time on the citation of 
Linneus under the synonymy.

There are two sheets marked, the first ‘“‘Mariscus 1” in 
Linneus’s hand, the second “Schcenus Mariscus” in Linneus’s 
hand; they are both 
= CLADIUM JAMAICENSE, Crantz. 
The diagnosis and citations of Linnexus agree.

The plant marked in Linneus’s hand Schenus Mariscus has 
been ticketed as subsequently Sch. aculeatus of the Sp. Pl.—quite
