LABIATE. 13 



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

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

 (.illasters beneath it. Bracts of the head lanceolate ; of the lower 

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

 subulate, shorter than the flowers. Pedicels glabrous. Cal)-x glabrous, 

 campauulate-cylindrieal ; teeth triangular, abruptly acuminated iiitu 

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

 Corolla twice as long as the calyx, glabi'ous without and within. 

 Nucules " smooth." (Balcer.) 



In wet places very rare. In a wet ditch at B;u-ton-under-Necdwood, 

 Staffordshire, Rev. Kirby Trimmer. In a ditch near Bedford, IJev. 

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

 between Llanrwst and Lhmberis, North Wales, and says that it was 

 found b)' Mrs. Walmsley by river-sides and brooks in Cheshire, particu- 

 larly in the neighbourhood of Aston House. 



England. Perennial. Autumn. 



Rootstock extensively creeping, and generally producmg numerous 

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

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

 2 inches long, longer than the petiole. Flowers m a roundish terminal 

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

 tinguishable from the leaves. Calyx of a purple coloin-, 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 }-ellow glands, dark 

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

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

 didynia). 



No doubt this is merely sub-specifically distinct from M. hirsuta ; 

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

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

 not m others.
