Very near Cotoneaster disticha LANGE (ScmsrEroer Handb. Laubholzk. I. p. 

 745, fig. 418 c-f u. 419, a-b, = Cotoneaster rotundifolia BAKER in Bot. -Mag. t. 

 8010), but easily distinguishable from it by the much smaller fruits. Also 

 near C. Zabeli (SCHNEIDER I.e. I. p. 749, fig. 420 f-h), but separable from it 

 also by the much smaller fruits. Most closely allied to Cotoneaster morriso- 

 nensis HAYATA, but different from it in having three carpels and not lenticel- 

 late branches and in the leaves which are a little larger and much darker above 

 in dried specimens. In C. mowisonensis, the carpels are usually two, and the 

 branches are more or less lenticellate.
