Doro-yanagi, Wata-no-ki ; a deciduous tree of the order Amen-
taceae growing in mountains of cold regions, attaining to a height
of 20-30 fts. It is a diaecious plant, and produces catkins before
the leaves come forth. When the seeds ripen, a kind of fibre like
cotton is exposed. The wood is white, fine grained, soft and
brittle, being principally used for matches.
563. Quercus glandulifera, Bl., Jap. Nara-no-ki 9
Konara ; a deciduous tree of the order Amentaceaa growing wild
to a height of 20-30 fts. It is a monaecious plant. Before
sprouting it produces catkins, with acorns on the cups. The
wood is hard arid strong, and is suited for fuel. The stems and
branches are used to cultivate a kind of mush-room called Shiitake
(140) on them. The kernels are eaten. The shape, quality and
use of these species are almost common to each other.
563. b. Quercus crispula, BL, Jap. Onara, Midsunara
; a species closely allied to the preceding. It is a large tree
found wild in mountains. It has the same uses as before.
563. C. Quercus variabilis, Bl., Jap. Wata-nara> Wata-
kunugi, Abemaki ; a species of Quercus (295) with thick bark
which is used as cork. The new bark, grown after the outer
bark was stripped off, is very suitable for this purpose. It requirse
about 10 years to get good bark.
563. d. Quercus serrata, Th., Jap. Kwmgi; the wood
of this tree (295) is the best as fuel.
564. Quercus acuta, 77*., Jap. Aka-gashi, O-gashi; an
evergreen tree of the order Amentacea3 produced in warm regions,
growing to a height of 20-30 fts. It is a monaecious plant. Its
acorn resembles that of Q. glandulifera (563). The wood is red
and hard, and is used to make wheels aud other articles.
564. b. Quercus gilva, Bl. y Jap. Ichii-gashi ; an ever-
green tree of the order Amentaceas. As it produces edible acorns,
it is described in the chapter of fruits (226. b.). It grows to a
height of 30-60 fts. It is a monaecious plant. The wood is red
