LAMIUM (Greek for throat, referring to the shape of 

 the corolla). Labiates. DEAD NETTLE. About 40 annual 

 and perennial herbs of the Old World, of which several 

 run wild in this country as weeds and others are cult, as 

 hardy border plants. Botanically, they are distinguished 

 by a 2-lipped corolla, of which the tube is somewhat 

 longer than the calyx, the upper lip ascending and con- 

 cave, and the lower one 3 lobed: stamens 4, in 2 pairs, 

 ascending under the upper lip: fls. in axillary or termi- 

 nal whorls, often rather showy: Ivs. opposite, mostly 

 crenate-dentate and petiolate: calyx awl-toothed. Not 

 to be confounded with Nepeta. 



Lamiums are diffuse mostly pubescent or hairy herbs, 

 commonly decumbent at the base and often almost trail- 

 ing. They are of the easiest culture in any open soil. 

 Useful for rockwork. The cult, kinds are perennial, 

 and are commonly propagated by division. 



maculatum, Linn.(Z/. dlbum and L. purpiireum, Hort., 

 not Linn. L. variegatum, Hort.). Straggling or half- 

 trailing herb, the tips ascending, slightly hairy: ivs. 

 long-petioled (except the uppermost), cord ate -ovate, 

 blunt, round-toothed: fls. 1 in. long, ascending in the 

 clusters, the upper lip strongly arched or hooded, the 

 tube 2-3 times longer than the calyx, hairy within. Eu. 

 Flowers usually purple-red, but sometimes varying to 

 white (when it is known as L. album, but the L. album 

 of botanists is a different plant, having pointed and 

 sharp-toothed Ivs. ) . The Ivs. are usually whitish blotched 

 along the midrib (var. variegatum), and in this form 

 it is common about old gardens, trailing in the waste 

 places. The plant is also run wild. L. purpiireum of 

 the botanists is annual. 



eriocephalum, Benth. Stem much branched, glabrous : 

 lower Ivs. long-stalked, puberulent, small, orbicular, 

 somewhat incise-crenate : floral Ivs. larger, deeply 

 toothed, sessile or nearly so: calyx villous; corolla 3-4 

 times longer than the calyx, straight, purple. Taurus. 

 Said by some to be annual. 



Gale6bdolon, Crantz, of Europe, with yellow fls. and 

 sometimes with yellowish foliage, is cult, in the Old 

 World, but it has not appeared in the Amer. trade.

LANDRETH, DAVID, founder of the oldest seed- 

 house in America,was born in 1752 at Haggerston, North- 

 umberland county, England. He came to America late 

 in the eighteenth century, making Philadelphia his home, 

 and establishing there, in 1784, a nursery and seed busi- 

 ness. Its location, on what was then known as High 

 street, is now covered by the building 1210 and 1212 

 Market street. The raising of trees and production of 

 seeds were conducted on land near by, particularly on a 

 tract at Twelfth and Filbert streets. This locality prov- 

 ing too contracted for the purpose, the nursery and seed 

 grounds were removed in 1789 to the "Neck," then con- 

 sidered far out of town, the place chosen being not far 

 distant from the site of the present arsenal. 



The subject of the present sketch, the younger David 

 Landreth '(Plate X), was born in Philadelphia in 1802. 

 When of suitable age he entered actively into his father's 

 business, which had considerably extended in Philadel- 

 phia, while a branch house had been opened in Charles- 

 ton, S. C. The young man's early duty was that of 

 manager of this Charleston branch. Of the Charleston 

 business, it will suffice here to say that it continued till 

 the era of the civil war, when it came to a sudden end 

 by the act of the Confederate States District Court,which 

 confiscated the real estate and merchandise alike, on 

 April 22, 1862. 



The younger David Landreth, in 1828, succeeded his 

 father as proprietor of the well-established and thriv- 

 ing business in Philadelphia, a business which was to 

 remain highly prosperous for half a century afterwards 

 under his fostering care. His time, however, was not 

 wholly occupied with the details of business, but was 

 turned at an early age towards the literature of hus- 

 bandry and to enterprises of public interest. Among 

 the latter may be mentioned the Philadelphia Horticul- 

 tural Society, of which, in 1827, he was one of the 

 founders and a vice-president, and in 1828 was elected 

 corresponding secretary, which office he held for seven
