shorter than those in that species, while in R. pratensis of this 
country the margins are rather denticulate than spinous- dentate. 
From the seeds of the Scandinavian R. cristatus I raised a plant 
which was almost identical with R. obtusifolius, Fries, except that 
the entire portion of the sepal was short, so that the whole was den- 
tate instead of triangular or oblong-triangular.” — John T. Boswell, 
June, 1875. 
Rumex conspersus, Hartm. “ Cowdenbeath, Fife, and Inverteel, 
Fife, 1873 and 1874. This plant appears widely spread wherever 
R. crispus and R. domesticus grow in company. If, however, it be a 
hybrid it is a perfectly fertile one, and like pratensis comes true from 
seed.” — J. Bosavell. 
Rumex crispus, L., var. subcordatus , Warren. “ Teffont, Wilts, 
October, 1872. Also seen at Lewes, Sussex, July, 1872. I have ven- 
tured for sake of reference to name this odd plant so provisionally. It 
differs from ordinary crispus by its great size (five or six feet) and by 
the shape of its enlarged sepals, most of which are more or less toothed. 
It approaches the R. propinquus of Prof. Areschoug paper, but is 
not that plant according to the Professor himself, to whom I for- 
warded a specimen.” — J. L. Warren. “ Of this form of R. crispus 
I have sent specimens from various places in Fife and Kinross, under 
the name of R. crispus , var. dentatus, Warren. In a letter received 
a few days ago from that gentleman he proposes to apply to the variety 
the name ‘ dentatus ’ or ‘ serratus,’ and, as will be seen, the new name 
is more appropriate than either of the older ones, which I believe have 
not been published. This variety has rather a lax panicle, having the 
branches frequently elongate, and not adpressed, by which it may . 
be always distinguished from R. domesticus. The enlarged petals 
are larger and broader than in the common form, being deltoid or 
subrotund-deltoid, very frequently denticulate or at least erose 
towards the base. Only one of the three bears a tubercle, which is 
variable in size and shape. The denticulation at the base of the 
petals is not a constant character, though their form appears to be 
hereditary. From the seeds of a plant of this variety found at Bal- 
muto, which had the petals quite entire, I raised plants which had 
them conspicuously dentate at the base, though still maintaining 
their subrotund-deltoid shape.” — J. T. Boswell, June, 1875. 
Rumex (sp. ). “ Single specimen sent from the side of a 
tidal inlet from the river Erne, a little below Efford, Holbeton, 
South Devon. Without tubercles, and considerably like R. domesticus , 
but possibly a variety of R. crispus. Only one root was found.” — T. 
B,. Archer Briggs, 1874. This Rumex is evidently a form of crispus , 
somewhat intermediate between vars. subcordatus and elongatus. It
