70 Prunella Pe?msylva?iica, 0. lanceolata. 



Root perennial, fibrous. Plant from ten to fourteen inches high. 

 Stems square, hairy. Leaves opposite, lanceolate, and broad-lanceo- 

 late, irregularly toothed, on short petioles. Nerves and costa conspi- 

 cuous. Upper pair of leaves sessile, embracing the spike which is long 

 and narrow after the plant has continued some time in flower. Bracteas 

 membranaceous, reticulated, ciliated, and reniform. Flowers hand- 

 some, labiated, of a lilac-purple colour, and expanding successively for 

 a considerable time. Calix consists of two lips, the upper one of which 

 is furnished with three short setaceous awns, the lower terminating in 

 two sharp teeth. Grows in grassy way sides, near the fences of grassy 

 fields, preferring moist soils. Flowers in August and September. 



The table represents the plant, in flower, of its natural size— the 

 spike being represented short and ovate, as in the first days of flores- 

 cence. It afterwards becomes elongated to three times the length of 

 the figure.
