name of reptans as having priority, and refers to Weber and 
Mohr, who speak of it as a manuscript name, and assert, that 
having compared Wahlenberg’s specimens of E. reptans with 
Michaux’s specimens of the North- American species, E, scir- 
poides, they find them identical, and consider them distinct from 
their own E. variegatum.^ Beck, however, gives the name of 
E. variegatum to the North American species, E. scirpoides, 
and unhesitatingly pronounces them to be identical ; f and 
Wahlenberg, in his comparatively modern work, the ‘ Flora 
Suecica,’ does not maintain the two varieties which he proposes 
in the ‘ Flora Lapponica,’ but, without expressing a doubt on 
the subject, gives his E. reptans as the species, and quotes the 
E. variegatum of Willdenow and of Smith as synonymous. It 
should, however, be observed that the normal form of E. reptans, 
as originally described by Wahlenberg, is a very small moun- 
tain form, with a quadrangular stem, and having black setiform 
teeth to the sheaths : there are European specimens in the her- 
barium of the late Mr. Winch, now in possession of the Linnean 
Society of London, but I have never seen similar examples from 
any part of Great Britain.
