to me, as far as I can ascertain, to approach very near to the rijj;ht 

 thing, if not the right thing actually."— J. L. Warren, 1874. '* This 

 is what I suppose to be the plant so named by the French botanists. 

 I suspect it to be * trigranulate ' R. nemorosm. I have sown seeds of 

 this, but they have not yet germinated." — John T. Boswell, 1875. 



Rumex^ hybrid between ^;;</c7i^;- and nemorosus ? *' Pasture, Tothill, 

 Plymouth, 8. Devon, July 31, 1873." ''Also waste ground, Torpoint, 

 East Cornwall, August, 1873." — T. R. Archer Briggs. " Both of these 

 docks appear to me intermediate between R. imlcher and R. conglome- 

 ratus, the one from Torpoint, East Cornwall, approaching most 

 closely to pulclier in its divaricate branches, while that from Tothill, 

 Plymouth, has the branches ascending or spreading, ascending as in 

 R. conglomeratios. None of the specimens have root-leaves, and the 

 leaves at the base of the branches on both are oblong, or oblong-strap- 

 shaped, both forms having minute leaves at the base of the whorls 

 of the lower branches. Very few fruits appear to have been matured, 

 though I was able to get a few apparently perfect seeds which are 

 sown but have not yet come up. The enlarged petals are about the 

 size of those of R. conglomeratiis, and consequently considerably 

 smaller than those of R. pidcher. Some of them are entire, while 

 others have one or two teeth on the margins towards the base. The 

 basal portion of the petal is strongly reticulated, with very prominent 

 veins, as in R. pulclier. The petals of the fruits which contain mature 

 seeds are each furnished with a large red grain similar to that on the 

 petals of R. conglomeratus. Sometimes the grains are of equal size, 

 sometimes one larger than the other two, and sometimes two of them 

 larger than the third. Had I seen the Torpoint plant only, I should 

 have thought it might be depauperized pulcher'^ — John T. Boswell, 

 June, 1875. 



Rumex ohtustfolms, L., var. 3. agrestis, Eries, Nov, El. Suec, 

 ed, ii,, 99? "Cultivated fields, Invertiel, Kirkcaldy, Eife, and at 

 Cowdenbeath, Eife, August, 1873. This plant differs from R. 

 obtiisifolius, var. Friesii, which is apparently the commonest form of 

 obtusifoliiis in Britain, in having the branches of the panicle curved 

 and ascending-erect, so that the panicle is much narrower and less 

 straggling than that of Friesii. The enlarged petals are considerably 

 smaller, and the teeth often shorter. Erom the var. sylvestris 

 it differs in having the spines at the edge of the petals always 

 present and long." — John T. Boswell, June, 1872. 



Rumex pratensis, M. & K. " Near Brodick, Arran, September, 

 1872, and Swanbister and Gear, etc., Orphir, Orkney, August and 

 September, 1873. These few specimens have been sent out, as it 

 increases the range of this doubtful plant in Britain. The British 

 specimens I have seen do not agree well with the Scandinavian 

 specimens I possess of R. cristatus, with the exception of a speci- 

 men shown me by the Hon. J. L. Warren from Sussex. This 

 has deltoid petals, and distinctly spiny margins, with strong veins 

 running out into the centre of the spine, as in R. ohfiisifolius, but 

 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. ohtusifolius, var. Friesii, exce])t that
