ROSACEAE. 
CoTONEASTER. 
(Family Rosaceae). 
Shrubs: deciduous or evergreen. 
Twigs slender, subterete: pith 
small, rounded, continuous. Buds 
solitary, sessile, ovoid or oblong, 
the 2 outer scales mostly parted 
and exposing the hairy interior. 
Leaf-scars alternate, minute, ellip- 
tical, raised: bundle-trace 1, in- 
distinct: stipules rather persistent 
on the leaf-cushion, leaving nar- 
row indistinct scars when fallen. 
Legves when present simple, en- 
tire. Fruit, often present, small 
drupe-like pomes with often in- 
curved sepals. 
Cotoneasters are among the 
favorite shrubs of Great Britain, 
but the species that prove so ef- 
fective in an insular climate are 
rarely capable of successful cul- 
tivation under continental con- 
ditions even though not subjected to excessively low winter 
temperatures. 
A considerable number of those most success- 
fully grown in the United States are native to countries of 
relatively dry climate, and some of the best of them are of 
recent introduction. 
The few winter-character references are:—C. integerri- 
mus (or vulgaris). Bosemann, 78; Fant, 19; Ward, 1:231, 
f. 118; Willkomm, 6, 7, 32, f. 42—C. nigra and C. tomentosa. 
Schneider, f. 151. 
1. Evergreen: low and spreading. 2. 
Deciduous: larger and mostly erect. 3.
