1. L. amplexicaule, Linn. (fig. 810). ffenbit. — A low, decumbent, 

 much branched annual, a few inches, or, when very luxuriant, near a 

 foot long. Lower leaves small, orbicular, on long stalks ; the floral 

 ones closely sessile, broadly orbicular, and deeply crenate or cut. The 

 flowers form 1, 2, or 3 compact whorls. Calyx softly hairy, with short 

 teeth. Corolla about half an inch long, of a purplish red, with a slender 

 tube ; the lateral teeth of the lower lip scarcely perceptible. 



In cultivated and waste places, throughout Europe and central and 

 Russian Asia, except the extreme north. Extending all over Britain. 

 FL the whole season. A variety, L. intermedium, Fries, with rather longer 

 teeth to the calyx, and more distinct lateral teeth to the lower lip of 

 the corolla, is occasionally found mixed with the common one, especially 

 in the more northern localities. 



2. L. purpureuni, Linn. (fig. 811). Red D, — A spreading annual, 

 like L. amplexicaule, and the lower leaves are likewise small and 

 orbicular, on long stalks ; but the upper leaves, even the floral ones, 

 are all shortly stalked, and ovate, heart-shaped, or triangular, often 

 pointed, and, in the common variety, less deeply toothed. Calyx-teeth 

 fine, and spreading. Corolla of a purplish red, shorter than in L, 

 amplexicaule, with a broader, more open tube, and a more hairy upper 

 lip ; the lower lip with a short fine tooth on each side. 



In cultivated and waste places, throughout Europe and western Asia, 

 except the extreme north. In Britain more common than L. amplexicaule, 

 especially as a garden weed. Fl. the whole season. A variety with the 

 upper leaves deeply cut, which occurs in western Europe, and has been 

 found in England and Scotland, is the L. incisum, Willd. (hybridum, 

 Vill.). 



3. L. album, Linn. (fig. 812). White D. — A rather coarse, hairy 

 perennial, with a shortly creeping stock, and decumbent or ascending, 

 branching stems, seldom above a foot high. Leaves stalked, coarsely 

 crenate. Flowers pure white, in close axillary whorls of 6 to 10 or 

 more. Calyx-teeth long, fine, and spreading. Tube of the corolla 

 curved upwards, and longer than the calyx, with an oblique contrac- 

 tion near the base, corresponding with a ring of hairs inside ; the 

 upper lip long and arched ; the lateral lobes of the lower one slightly 

 prominent, with a long, fine tooth. 



Under hedges, on banks, and waste places throughout Europe and 

 Russian Asia, except the extreme north. Extends all over Britain, 

 although becoming rare in the Scotch Highlands. Fl. the whole season. 

 The leaves are occasionally marked by a white line or spot in the centre, 

 but less frequently so than in the following species. 



4. L. maculatum, Linn. (fig. 813). Spotted D. — Closely resembles 

 L. album in every respect except in the colour of the flower, which is 

 purple-red instead of white, and in the ring of hairs in the tube of the 

 corolla, which is transverse instead of oblique. The leaves are also 

 more frequently marked in the centre with a broad white line or spot. 

 It is still very doubtful whether it may not be a mere variety of L, 

 album, with which I had formerly united it. 



With nearly the same geographical range as L. album, it is, however,
