and Central Europe. It has produced a number of well-marked varieties, of 
which the Park has—bullata, Zewdon ; apparently a garden form, with blis- 
tered or rough leaves. laciniata, London; with narrow almost pinnately- 
divided leaves, the lobes of which are acuminate. pendula, ANe///; is a 
garden form with conspicuously drooping branches. subperennis, 4/p/. De 
Candolle ; has long been cultivated in British gardens under the name of Q. 
dentata, Watson. To this same variety Alph. De Candolle refers both Q. Cerris 
Futhamensis, Loudon, and Q. Cerris Lucombeana, Loudon; which has also 
produced a form (c77sfa) with curled-edged leaves. May not asplenifolia and 
Comptonifolia of the gardens be the same ? 
Quercus cinerea, Michaux. UPLAND WILLOW OAK. From Virginia 
southward. A small, biennial-fruited tree; leaves oblong, hairy beneath ; acorn 
with a saucer-shaped cup. @Q. Phellos, Spach, is a synonyme. ‘The variety 
pumila, Ye Candolle, or Q. sericea, Willdenow, is placed under Q. pumila, 
Walter, of this list. 
Quercus coccinea, Wangenheim. SCARLET OAK. Large, biennial-fruited, 
native tree of the Black Oak group; the smooth, deeply-cleft leaves turning 
red in autumn. Wood open-pored, making bad staves, poor fuel, and is seldom 
used in the arts. Bark, however, used in tanning. It is sometimes wrongly 
called SPANISH OAK, which is Q. falcata, Michaux. 
Variety tinctoria, Gray. QUERCITRON, YELLOW- BARKED, or BLACK OAK; 
is now generally regarded as a variety of the above, “ with more pointed and 
longer buds, broader less lobed leaves, and more pointed acorns.’’ It is 
Q. Americana, Plukenet, according to Loudon. The bark is used in tanning, 
and the cellular tissue furnishes the quercitron dye. Wood is open-pored, but 
made into staves for barrels to hold the less penetrating liquids. Wood fair 
in quality, but by no means equal to that of the White Oak. There are other 
less important varieties. 
Quercus dentata, 7hunberg? Native of Japan. Acorn matures in a 
single year; young branches densely brownish hairy; obovate leaves wavy 
margined or lobed, lobes obtuse, but with short projecting veins. (From 
want of proper material, and from having no authority for the name, it is not 
certain that this may not be the form of Q. Cerris cultivated in British gardens 
as Q. dentata.) 
Quercus falcata, Michaux. SPANISH OAK. A _ good-sized, biennial- 
fruited tree, ranging from New Jersey to Illinois and southward; acorn 
roundish ; leaves deeply and sharply lobed, lobes somewhat scythe-shaped, 
except the straight terminal one. Wood poor, but bark may be used in 
tanning. 
Quercus Georgiana, J/. A. Curtiss. GEORGIAN Oak. A biennial-fruited 
shrub of the Black Oak group; leaves smooth, narrowly oval or obovate, entire 
or wavy-toothed, or even lobed. ‘ Acorn-cup shallow, with its scales nearly 
glabrous, obtuse, and appressed.”” Regarded by Engelmann as coming very 
near Q. palustris. Confined, so far as now known, to Stone Mountain, in 
Georgia. 
Quercus heterophylla, Afichaux the younger. BArTRAM’s Oak. A 
biennial-fruited, good-sized tree, with oblong or somewhat wedge-shaped more 
or less lobed leaves. Considered by Alph. De Candolle as a mere variety 
of Q. aguatica, and by Engelmann regarded as a hybrid between Q. Phellos
