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 Bosemann, 

 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 somewhat-hairy: leaf -scars broader. C. chinensis.
