 dndreee, F. Muell.). Trunk 70-80 ft.: Ivs. several ft. 

 long ; rachis very broad and thick, glabrous or slightly 

 scurfy; segments numerous, the longer ones 1% ft. 

 long, /^-l in. hroad, acuminate and entire or slightly 

 notched. grtM-n ahove, ashy glaucous beneath. Queens- 

 land. F.S. 18:1910.

 Cunnhii/lHtnu'i, H. Wendl.). Trunk and general habit 

 like the preceding, but the segments acuminate and 

 entire or scarcely notched. Queensland and N. S. W. 

 B.M. 4961 as Seaforthia elegans. 



AKCTIUM (from Greek word for bear, probably al- 

 luding to the shaggy bur). Compbsitce. 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. 



Lappa, Linn. (Ldppa major, Gaertn.). 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). 



ARCTOSTAPHYLOS (Greek, bear and grape). Erica- 

 fete. 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 -seeded, separate or co- 

 herent cells. About 30 species in N. 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 polifolia are beautiful in flower, and well worth a 

 place in the greenhouse or in the garden in temperate 

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

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

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

 Includes Comarostaphylis.
