Ericaceae. 



Pieris. Stagger Bush. 

 (Family Ericaceae). 



Shrubs: evergreen or deciduous. 

 Twigs rather slender, 3-sided or 

 finally terete: pith somewhat 3- 

 sided, continuous. Buds small, 

 subglobose to conical, with 2-5 ex- 

 W ^7 posed scales ; the end-bud lack- 



i ^i\'/J^ ing. Leaf-scars alternate, small, 



half-round or triangular, somewhat 

 raised: bundle-trace 1: stipule- 

 scars lacking. Leaves, when pres- 

 ent, simple, entire and revolute or 

 serrulate. The small globose or 

 urn-shaped capsules are often pres- 

 ent in winter. 



As its common name indicates, 

 the stagger bush is poisonous to 

 stock, like Kalmia, etc. The 

 species of Pieris have been placed 

 in the genus Andromeda fre- 

 quently; and they are placed un- 

 der Lyonia by some botanists; as 

 they have been placed by others in Leucothde.
