riERIS 



moist, well-drained and porous soil, but dislike lime- 

 stone and heavy clay; a partly shaded situation suits 

 them best. Prop, by seeds treated like those of Azalea 

 or Rhododendron; also by layers, and the evergreen 

 ones by cuttings of almost ripened wood in August 

 under glass, kept during the winter in a cool green- 

 house. They root very slowly; cuttings taken from 

 forced plants root more readily. About 10 species in 

 N. Amer. and in Asia from Hinial. to Japan. Caly.x- 

 lobes valvate or distinct; corolla globose or urceolate ; 

 stamens 10 ; anthers obtuse, with a pair of awns near 

 the base or the filaments 2-toothed below the apex : cap- 

 sule with dehiscent valves ; seeds linear-oblong, not 

 winged, with membranaceous testa. Often included 

 under Aiidn.iiMila. Clirsely allied to Lyonia, but dis- 

 tinguishi'.i Ij\ it- iiwnlrss anthers, and to Zenobia, which 

 has thi- aiiihri- I iiwn.il at the apex. The foliage of

PILEA 



Dwarf form with small linear-oblanceolate Ivs. Japanese 

 botanists speak of a variety with the racemes a foot and 

 more long: this form seems to be not yet introduced. 

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

 evergreens.
