downy on both surfaces; branches tomentose ; male peduncles 
usually 3-flowered ; male flowers with about 20 stamens, and 
female 8; flowers quadrifid ; style 4-cleft; stigmas bifid. 
h.G. Native of China, Cochinchina, and Japan; and is also 
cultivated in those countries, as also in Bengal. D. Chinénsis, 
Blum. cat. hort. buit. p. 110. and act. soc. batav. 9. p. 167. 
Kouis or Kaki, Kempf. amen. t. 106. Fruit globose, 8- 
celled, size of a small orange, yellow when ripe, abounding in 
yellow, fleshy, edible pulp; it is tolerably pleasant, but by no 
means equal to a good apple; eaten plentifully occasions diar- 
rhoea. They are preserved in the same manner as the fig, by 
sprinkling meal or sugar over them. There is a variety of this 
species with an ovate fruit.
