96 ROSACEAE. 
CHAMAEBATIARIA. 
(Family Rosaceae). 
Small shrubs, stellate and var- 
nished: evergreen. Twigs terete, 
rather slender: pith small, round- 
ish, continuous. Buds small, 
promptly developing into short 
leafy spurs. Leaf-scars alternate, 
small, half-round or somewhat 3- 
angled, low, concave: bundle-traces 
3, impressed: stipule-scars_ re- 
latively large, concave, confluent 
with the leaf-scar, each with a 
distinct impressed bundle-trace. 
Leaves petioled, elliptical, twice 
pinnatifid or almost  bipinnate, 
with minute somewhat separated 
blunt segments. 
Though they are not very 
closely related in the family Re- 
saceae, Chamaebatiaria and 
Chamaebatia are rather similar in 
their very finely divided fern-like 
foliage. They are readily distinguished by the leaves of the 
former being not quite twice pinnate, while those of the lat- 
ter are essentially thrice pinnate. No other plant among 
these here considered has a leaf-scar nearly divided into three 
equal parts, as that of Chamaebataria is. 
Twigs reddish-brown: leaf- and stipule-scars white. 
C. Millefolium.
