ERICACEAE.

LYONIA. 

 (Family Ericaceae). 



Shrubs or sometimes subar- 

 borescent: evergreen or decidu- 

 ous. Twigs slender, somewhat 3- 

 sided, becoming terete. Buds soli- 

 tary, sessile, small, oblong, more 

 or less flattened against the stem, 

 with 2 exposed scales. Leaf-scars 

 alternate, minute, low, half-round 

 or crescent-shaped : bundle-trace 1 : 

 stipule-scars lacking. Leaves, when 

 persistent, simple, entire or ob- 

 scurely serrulate, and scurfy be- 

 neath. 



As with Pieris, Lyonia was for- 

 merly merged in Andromeda, and 

 the generic name Xolisma has 

 been used for its species, which 

 occur in a number of variants 

 which have been thought by some 

 botanists to represent distinct 

 species.
