4o8 LAMIACEAE 



Native. Agrestal. Septal. Cultivated and waste ground, hedges. 



borders of and open places in veoods, &c. Common and generally 



distributed. Often abundant in cleared woodland. A. June-Oct. 



First record. Sonning, Mr. S. Ruclge, i8oo, in Herb, Brit. Mus. Published 



as G. tetrahit, Dr. Noehden in Mavor's Agr. Berks, 1809. 



G. Tetrahit is a variable species. It exists under two important 

 modifications which are sub-specifically distinct. The first of these, 

 which I call the type, is the sylvan plant, which is sometimes as much 

 as four feet high. This has a corolla twice the length of the calyx 

 tube. The flowers, usually dull rose, are sometimes w?iite, /. alba, 

 occasionally pale yellow. Under this I place the following variety. 



Var. NIGRICANS, Brebisson, Fl. de la Normandie, 246, with almost 

 black calyces ; it is the Lamium cannabinum Jloribus albis, veriicilUs pur- 

 jyurasceniibus of Doody, in Ray, Syn. ii. App. 342 (1696). Doody says he 

 noticed it for many years, and ' toto habitu a vulgari differre videtur.' 

 Ill its extreme form it is a striking plant from the contrast of the pale 

 flowers with the purplish-black verticillasters. It has been noticed at 

 Wytham, Catmore, Mortimer, Finchampstead, Risely, Blackwater, 

 Windsor Park, &c. 



The second modification, which at least deserves sub-specific rank, 

 is the var. bifida Boenn. Prod. Fl. Monast. 178, as a species), Syme, 

 1. c, t. 1079. This is a much smaller plant, about 6-9 inches, with a 

 much smaller and shorter corolla occurring among the corn rather 

 frequently. It was fir.st noticed in Berkshire, near Sunningdale, by 

 Mr. H. C. Watson. I have seen it in all the districts, as at Cumnor, 

 Frilford, Boar's Hill, Bourton, Wallingford, Yattendon, Lambourn, 

 Bx-impton, Reading, Twyford, Winkfield, Shurlock Row, &c. 



Galeopsis Tetrahit is found plentifully in all the bordering counties.
