base, subacute, sharply serrate, glabrous above and beneath. Flowers 

 in a Bubglobular terminal head, with or without one or two verti- 

 cUlasters beneath it. Bracts of the head lanceolate ; of the lower 

 whorls, when present, similar to the leaves ; bracteoles strapshaped- 

 subulate, shorter than the flowers. Pedicels glabrous. Calyx glabrous, 

 campanulate-cylindrical ; teetli triangular, abruptly acuminated into 

 long subulate points, two-thirds the length of the tube, glabrous. 

 Corolla twice as long as the calyx, glabrous without and within. 

 Nucules "smooth." {Baker.) 



In wet places very rare. In a wet ditch at Barton-under-Needwood, 

 StafFordshu-e, Rev. Kirby Trimmer. In a ditch near Bedford, Rev. 

 Dr. Abbot. Sole found it in a small brook or ditch near Capel-Carey, 

 between Llam'wst and Llanberis, North Wales, and says that it was 

 found by Mrs. Walmsley by liver-sides and brooks in Cheshire, particu- 

 larly in the neighbourhood of Aston House. 



England. Perennial. Autumn. 



Rootstock extensively creeping, and generally producing numerous 

 stolons above ground, with small leaves. Stems about 2 feet high, 

 muck branched, the branches spreading. Lamina of the leaves 1 to 

 2 inches long, longer than the petiole. Flowers in a romidish terminal 

 head, with 1 or 2 verticillasters beneath it in the axils of bracts undis- 

 tinguishable from the leaves. Calyx of a purple colour, on which lines 

 of yellow dots (glands) are very conspicuous. Corolla \ inch long, 

 reddish-lilac, with the stamens apparently always included, and the 

 style protruded. Plant glabrous, dotted with yellow glands, dai'k 

 green, generally tinged with purple. Odour very aromatic, resembling 

 that of the Bergamot Orange or that of the Oswego Tea (Monarda 

 didyma). 



No doubt this is merely sub-specifically distmct from M. liirsvita ; 

 but, as I have been unable to follow out the grouping of the mints 

 into super-species, it would be undesirable to do so in some cases and 

 not in others.
