2. G. ladanum (Red Hemp-nettle). Stem and leaves downy 

 with soft hair ; stem not swollen below the joints. Resembling 

 the last, but only about 8 or 9 inches high. The flowers are purple, 

 mottled with crimson. Gravelly and sandy fields ; not uncommon. 

 Fl. August, September. Annual. 



3. G. ochroleuca (Downy Hemp-nettle). Resembles G. Ladanum, 

 but more downy. The flowers are larger and pale yellow. Culti- 

 vated fields ; rare. Fl. July, August. Annual. 



11. Lamium (Dead-nettle) 



I. L. album (White Dead-nettle). Leaves heart-shaped, taper- 

 ing to a point, serrated, stalked. A common, but not inelegant 

 weed, well marked by its large pure white flowers and black stamens. 

 So closely does the foliage of this plant resemble that of the Stinging 

 Nettle that many persons are afraid to handle it, supposing it to 

 be a Nettle in flower. The flowers of the latter, however, are green, 

 and so small that they would be passed unnoticed but for their 

 growing in spiked panicles near the summit of the stem. The 

 square stem of the Dead-nettle is enough to distinguish it at any 

 stage of its growth. Hedges and waste ground ; abundant. 

 Fl. all the summer. Perennial. 



2. L. purpureum (Red Dead-nettle). Leaves 

 \ heart- or kidney- shaped, blunt, crenate, the lower 

 ones on long, the upper on short stalks. A com- 

 mon weed of spreading habit, distinguished by 

 the purple tinge of its foliage, crowded upper 

 leaves, and small purple flowers. A variety with 

 deeply cut leaves is occasionally found, and is 

 known as L. incisum (Cut-leaved Dead-nettle). 

 Cultivated ground and by waysides ; common. 

 Fl. all the summer. Annual. 



Lamidm Pupureum 3- L. maculatum (Spotted Dead-nettle). Very 

 [Purple Dead-nettle) nearly allied to L. Album, but distinguished by 



its leaves each having a white blotch, and by 



its large purple flowers. A somewhat uncommon garden escape. 



Fl. summer. Perennial. 



4. L. ampiexicaule (Henbit-nettle). From a few inches to a foot 

 high, and of low, branching habit. Leaves round and deeply cut, 

 lower ones on long stalks, floral ones sessile. The flowers, which are 

 of a purplish red, are borne in from 1-3 whorls. A common weed. 

 Fl. almost all the year round. Perennial. 



5. L. Galeobdolon (Yellow Dead-nettle, Archangel, Weasel-snout). 

 y\ . Resembling in habit the common White Dead-nettle, but rather 



teller ; the leaves are narrow and more pointed, and the flowers,
