ABCTIUM (from Greek word for bear, probably al- 

 luding to the shaggy bur). Gompbsita. Burdock. A 

 few coarse perennials or biennials of temperate Eu. and 

 Asia, some of them widely distributed as weeds. Invo- 

 lucre globular and large, with hooked scales, becoming 

 a bur : receptacle densely setose : pappus deciduous, of 

 bristles : Ivs. large and soft, whitish beneath: plant not 

 prickly : fls. pinkish, in summer. 



L&ppa, Linn. (Ldppa mdjor, Gsertn.). Common Bur- 

 dock. The Burdock is a common and despised weed in 

 this country, although it is capable of making an excel- 

 lent foliage mass and screen. In Japan it is much cult, 

 for its root, which has been greatly thickened and ame- 

 liorated, affording a popular vegetable. It is there 

 known as Gobo (see Georgeson, A.G. 13, p. 210). 



AECTOSTAPHYLOS (Greek, bear and grape). EricA- 

 cece. Manzanita. Shrubs or small trees ; Ivs. alternate, 

 evergreen, usually entire, rarely deciduous : fls. small, 

 urceolate, mostly white, tinged red, in terminal, often 

 panicled racemes, in spring : fr. usually smooth, a red 

 berry or rather drupe, with 1-10 1-seedcd, separate or co- 

 herent cells. About 30 species inN. and Cent. Amer., 

 2 species also in N. Eu. and N. Asia. Handsome ever- 

 green shrubs, though generally with less conspicuous fls. 

 and frs. than those of the allied genus Arbutus. Some 

 Cent. Amer. species, however, as A . arbutoides , arguta 

 and politolia are beautiful in flower, and well worth a 

 place in the greenhouse or in the garden in temperate 

 regions ; of the American species, A. PringJei, viscida 

 and bicolor are some of the handsomest. Only the trail- 

 ing species are hardy north. For culture, see Arbutus. 

 Includes Comarostaphylis.
