ERICACEAE. 279 
PHYLLODOCE. Mountain Heath. 
(Family Ericaceae). 
Low matted shrubs: evergreen. 
Twigs slender, ridged below the 
leaf-scars: pith minute, continu- 
ous. Buds minute, solitary, ses- 
sile, of scarcely evident structure. 
Leaf-scars alternate, minute, cres- 
cent-shaped, raised: bundle-trace 
1, searcely distinguishable:  sti- 
pule-scars lacking. Leaves small, 
oblong, minutely serrulate. The 
small ellipsoid capsules, erect on 
long slender glandular staiks, are 
evident in winter. Sometimes 
placed in Bryanthus. 
Winter-characters of Phyllodoce 
caerulea are given by Fant, 51. 
The phyllodoces afford another 
example of the occurrence of iden- 
tical or equivalent species in high 
latitudes on both continents, with 
extension away from the pole at 
increased altitudes. 
Midrib glabrous: fruit-stalks not bristly. (1). P. Breweri. 
Midrib puberulent beneath: pedicels bristly. (2). P. caerulea.
