¥ Q. p. 5 heterophilla. Q. salicifolia Hort., Q. laciniita Lod. Cat., Q. fili- 
cifdlia Hort., Q. Fennéssi Hort. (Our jig. 1544.) — In this variety 
the leaves vary exceedingly in magnitude, in shape, and in being lan« 
ceolate and entire, cut at the edges, or deeply laciniated. 
% Q. p. 6 folits variegatis Lodd. Cat. — Leaves variegated with white, with 
some streaks of red. When finely grown, a very ornamental tree. 
¥ Q. p. TV purpurea, Q. purptirea Lodd. Cat.— Young shoots, and the foot- 
stalks of the leaves, tinged with purple. Young leaves, when they first 
come out, almost entirely purple, and very striking. A tree, which is 
among the oaks what the purple beech is among the beeches. There 
is a specimen 30 ft. high at Arno’s Grove, Southgate. 
Other Varieties. Q. p. Hodgins, Q. p. cinérea, and Q. p. dilcis are 
described in our first edition. The varieties of British oaks which might 
be selected from extensive woods of that tree are without end. 
Quércus pedunculata, both in Britain and on the Continent, is generally 
found on better soil than Q. sessiliflora ; and its wood splits more easily, and 
is lighter, than the wood of that species. In France, the chéne-a-grappes is 
always planted in preference to the chéne-rouvre, where the soil is sufficiently 
good, When both oaks are planted together in good soil, the red oak (Q. 
sessiliflora) outgrows the white oak (Q. pedunculata) ; and, when either oak 
grows on particular descriptions of soils, with bad subsoils, the wood assumes 
a brown or dark colour, and is found, when worked up, to be of comparatively 
short duration. Hence, a good deal of confusion has arisen as to the com- 
parative value of the wood of these two species. For splitting, the white oak 
is to be preferred ; and, with respect to durability, we believe that depends 
more on the soil, and on the rapidity or slowness of growth, than on the 
species. (See Ard. Brit., 1st edit., p. 1731. to p. 1842.; and Gard. Chron., 
vol. i. p. 70.)

Derivation. ‘The name of Chestnut Oak is given to this species, because its wood is supposed by 
some to resemble that of the sweet chestnut, as do the leaves in a slight degree, of some of the 
varieties. The French names imply the male oak, the red oak, and the hard oak, The German
