126 ROSACEAE. 
MADDENIA. 
(Family Rosaceae). 
Shrubs or small trees: decidu- 
ous. Twigs moderate, rounded: 
pith rather small, rounded, con- 
tinuous, ‘pale. Buds solitary or 
collaterally multiple, sessile, elon- 
gated-ovoid, with half-a-dozen 
more or less pointed scales, the 
end-bud lacking. Leaf-scars al- 
ternate, somewhat raised, broadly 
crescent-shaped, rather small: 
bundle-traces 3: stipule-scars lack- 
ing. 
On its general winter-characters, 
Maddenia hypoxantha would be 
taken for a species of Prunus 
lacking the terminal bud as the 
plums do, but with the peculiar 
pitted marking of its bud-scales 
shown by the common _ choke- 
cherry of the Eastern States. Sev- 
eral Asiatic species are known, of 
which one has been introduced to a small extent in this 
country. 
Glabrescent: bud-scales brown, pitted. M. hypoxantha.
