fill for coverins arbors and verandas. From a well- 

 established root, viues will grow 40-60 ft. in a single 

 season, producing a profusion of very large Ivs. In the 

 North the plant dies to the ground in the winter, but in 

 the South the top becomes woodj-. The large fleshy root 



being 4-5 ft. long. Georgeson writes of tlie plant in 

 Japan: "The roots are fleshy and yield starch of excel- 

 lent quality; the touyh tiber of the inner bark is manu- 

 factured into a sort of cloth which combines flueness with 

 remarkable .strength; and in certain situations the vine 

 is unparalleled for ornament and shade." The fls. are 

 borne on the old or woody stems, but these stems usually 

 do not persist north of Philadelphia, and even rarely 

 there. With age, the tops are more likely to survive the 

 winter. Prop, by division of the roots, or by seeds when 

 they can be had; also by cuttings. l_ jj 3_

 in open or partially 

 shaded positions. They 

 are readily propagated 

 by division. Divide the

PURSLANE 



PnLTEN.ffiA is one of many genera of Australian 

 shrubs of the legume family with clusters of yellow 

 pea-shaped flowers. Pultenteas are practically unknown 

 in American floriculture. Seventy-five species are dis- 

 tinguished in Flora Australiensis 2:107-140 (1864). For 

 general purposes these plants are presumably inferior 

 to Cyti.us Ca,wric„sis.

 short lobes 5-7 and persistent on the top of the fruit (as

and Baltimore. It is also grown as a conservatory 

 plant, blooming in winter as well as in summer. For 

 ornament, the double-flowering kinds are the most 

 popular (P.S. 13:1.385, as P. Granatum Legrellei). 

 There are many named varieties. The treatment of the 

 fruit-bearing varieties is discussed uuder Pomc3»-a«a(c. 

 Var. nina, Hort. {P. n&na, Linn.). Dwarf Pome- 

 granate, seldom growing higher than a man, and usually 

 treated as a pot-plant in the North. It is the best kind 

 for greenhouse use. The double-fld. form is most com- 

 mon. B.M. 034. It is as hardy as the species, and is 

 suitable for outdoor work where the climate is not too 

 severe. On the Pacific coast it is grown as a hedge 

 plant as far nf)rth as San Francisco. Both this and the 

 species are easily grown by cuttings of dormant wood, 

 as currants are, but the cuttings should be started in- 

 doors with some heat. l^ jj_ g^
