e|)ariii;,'ly ciliated, spreading, loiigrr tliaii the tiihc ; tube nearly 

 straight, searoely oblicjue at the mouth. Corolla tul)e longer than the 

 calyx-teeth, with a. very conspicuous oblicjue ring of hairs within, 

 curved upwards, with a projecting sac immediately above the base on 

 the lower side, gradually enlarged upwards to the apex; upper lip 

 greatly vaulted, obtuse, densely hairy; lower lip with the lateral 

 lobes subulate (rarely enlarged and subquadrate-oblong), the middle 

 lobe obcordate. ^Jucules about twice as long as broad, destitute of 

 white scales. 



By roadsides, borders of fields, in waste places, and on ditch banks, &c., 

 &c. Very common, and generally distributed in England and the south 

 of Scotland. Rare north of the Forth and Clyde, though extending 

 to Stirling and Forfarshire; in Moray it occurs only as an introduced 

 j)lant. Local and rare in Ireland, where it has not been oliserved west 

 of the Shannon, luid is considered to be probal)ly introduced in the south. 



England, Scotland, Ireland. Perennial. Spring to Autumn. 



Kootstock generally subterranean, producing numerous stolons. 

 Stems 6 inches to 2 feet high, succulent. Leaves much resembling 

 those of the comnum nettle; the lamina 1 to 3 inches long. Bracts 

 imdistinguishable from the leaves, except from their having much 

 shorter stalks. Verticillasters 6 to 18-ilowered. Cal3'x tube gene- 

 rally spotted or stained with dark purple; teeth very long, weak, 

 widely spreading. Corolla ^ to 1 inch long, cream white. Nucules 

 1 inch long, olive, destitute of the white scaly specks which occur on 

 the nvicules of the annual species. Plant more or less pubescent 

 with long hairs, those on the stem reflexcd. 



Mr. Buckman found a curious variety near Cirencester Agricultural 

 College : in this plant the lateral lobes of the under lip are greatlv en- 

 larged, instead of being minute and subulate, as in the ordinary form. 



L. album bears considerable resemblance to L. maculatum, but the 

 creeping j)art of the stem is more subterranean, the ilowering portion 

 more erect ; the leaves longer, more deeply and sharply tootlied, less 

 rugose; verticillasters with more numerous flowers; corolla tube 

 abruptlv saccate innnediati.'ly above the base (which is not the case in 

 L. maculatum), and gradually enlarged upwards, the upper lip more 

 pubescent; calyx not curved or oblique at the mouth, the teeth much 

 longer.
