ROSACEAE. 103 
CHAENOMELES. Japanese Quince. 
(Family Rosaceae). 
Rather closely branched and 
small shrubs with slender termi- 
nal and axillary twig spines: de- 
ciduous. Twigs very _ slender, 
round or somewhat angled from 
the nodes: pith small, pale, 
rounded, continuous. Buds soli- 
tary, small, sessile, round-ovoid, 
with few exposed scales, collater- 
ally branching in spine-formation, 
the end-bud lacking. Leaf-scars 
alternate, small, linear or cres- 
cent-shaped or narrowly triangu- 
lar, strongly raised: bundle-traces 
3, minute: stipule-scars somewhat 
elongated. (Cydonia). 
The Asiatic or “flowering” 
quinces, which differ from the 
true quince in having a consider- 
able number of seeds in each of 
the rather large core-cavities of 
their fruit, have been placed in the genus Cydonia very com- 
monly. Their winter-characters are discussed by Bésemann, 
49; and Schneider, f. 128. 
In an article on the winter-storage of food in the tissues 
of woody plants, published in the second volume of the Me- 
moirs of the Torrey Botanical Club, Halsted discusses the 
spines of (C. japonica as such food-reservoirs. 
Twigs glabrous: leaf-scars narrow. (1). C. japonica. 
Twigs soméwhat-hairy: leaf-scars broader. C. chinensis.
