PIERIS 



PIGAFETTA 



inside decoration with its slender racemes of pure 

 white flowers hanging over the glossy bright green foli- 

 age. The species of Pieris, like other Ericaceae, grow 

 well in a moderately moist well-drained and porous 

 soil, but dislike limestone and heavy clay; a partly 

 shaded situation suits them best. Propagation is by 

 seeds treated like those of 

 azalea or rhododendron ; 

 also by layers, and the ever- 

 green kinds by cuttings of 

 almost ripened wood in 

 August under glass, kept 

 during the winter in a cool 

 greenhouse. They root very 

 slowly; cuttings taken from 

 forced plants root more 

 readily.

 panicles formed 

 the previous year

 naked during the 

 winter: Ivs. ser- 

 rulate.

 Mn. 5, p. 132. M.D.G. 1898 : 333. Very desirable ever- 

 green shrub for its hardiness and earliness of the fls.

 Fig. 2946. Shrub, with spreading branches or some- 

 tunes small tree to 30 ft.: branches glabrous: Ivs. 

 crowded at the ends of branches, obovate-lanceolate or 

 oblanceolate, crenately serrulate, narrowly cuneate at 

 the base, glabrous, l>^-2^ in. long: fls. in pendulous

 S.I.F. 1:78. Var. albo-marginata, Rehd. Lvs. with 

 whitish margin and smaller. Var. pygmaea, Maxim. 

 Dwarf form with small linear-oblanceolate Ivs. Japa- 

 nese botanists speak of a variety with the racemes a 

 foot and more long; this form seems to be not yet intro. 

 P. japonica is one of the most graceful early-blooming 

 evergreens. 



formSsa, D. Don (Andrdmedaformdsa, Walt.). Shrub 

 or small tree, to 20 ft. : branchlets glabrous: Ivs. crowded 

 at the end of the branchlets, elliptic-oblong to lanceo- 

 late, acuminate, broadly cuneate at the base, finely 

 serrulate, glabrous, lustrous above, 2-5 in. long: fls. in 

 terminal drooping or spreading panicles, to 6 in. long; 

 corolla urceolate, white or tinged with pink, %\n. long.

5:162. Very similar to the preceding species, but 

 larger in every part; less hardy. 



BB. Fls. in axillary clusters, forming terminal leafy 



racemes: Ivs. entire.
