herbarium of the Flora Virginica. The fruit of it is not well developed, 
but the slender pedicels and the foliage show that it is the R. orbiculatus 
of the later edition of my * Manual.’ But the specimen retained in Clay- 
ton's herbarium to represent the species, and the only Rumex in that 
is, as I believe, R. obtusifolius. The difference in the plants accounts 
for the remark of Linnzus : “ Plantam Gron. in Fl. Virginica habui a 
Authore, que non rubra erat caule aut costis." For Clayton's character, 
rinted 
as ronovius in the first edition of Flora Virginica, was :— 
* Lapathum foliis longis latis vix acuminatis, costis caulibusque rubentibu 
Gronovius. And the specimen sent was perhaps Clayton's other species, 
viz. —“ Lapathum aquaticum foliis longis," etc., which Linneus referred 
to R. verticillatus. As to the R. Britannica of Michaux, Pursh, and even 
: : 'e is nothing in his cha- 
racter to certify it. A considerable difficulty in identifying the Linnean 
species by the description grew out of the comparison in the ‘ Species
