Gen. Char. Sterile and fertile Flowers on the same plant. 
Sterile Ploivers (figs. 1 & 2.) in a long, slender, lax, pendulous 
catkin, deciduous. Calyx fbractea, Loud.,/ (see fig. 2.) a scale of 
1 leaf, in 4, 5, or more, deep, often divided, segments. Corolla 
none. Filaments (see fig. 2.) from 5 to 10, short, awl-shaped. 
Anthers roundish, of 2 channelled lobes. Fertile Flowers (see figs. 
3 & 4.) on upright, axillary peduncles ; a few upon a peduncle. 
Calyx double, both permanent, outer one hemespherical, coriaceous, 
single flowered (see figs. 4 & 6.), intire, much enlarged in the 
fruit (see fig. 7, b), and externally scaly, or tuberculated ; inner of 
one leaf, in 6 minute, deep, sharp, downy, segments, closely sur- 
rounding the germen and base of the style. Corolla none. Germen 
(fig. 5,) 1, globose, of 3 cells, with the rudiments of 2 seeds in each, 
that at first are erect, but soon after pendulous. Style (see fig. 5.) 
short. Stigma 3-lobed, rather fleshy. Fruit (see fig. 7, a.) an 
acorn, mostly oblong, or egg-shaped ; its lower part invested with 
an imbricated cup pouter calyx,/ (fig. 7, 6) ; its base scared; the 
rest of its surface invested with the adherent, coriaceous, smooth, 
inner calyx, which is separable by art ; cell 1, seed 1, very rarely 2. 
Cotyledons large, half-egg-shaped ; without any separate albumen ; 
embryo at the top. 
The loose, pendulous catkins of sterile flowers, with a calyx of 1 leaf in several 
deep segments ; the fertile flowers with a scaly cup-shaped, entire, outer calyx ; 
a germen with 3 cell3, 2 of which are abortive, and a 3-lobcd stigma ; and the 
fruit a 1-celled, 1-seeded acorn, seated in the cup-shaped, enlarged, outer calyx 
or involucrum ; will distinguish this from other genera, in the same class and order. 
Two species British. 
QUB'RCUS ROBURJ. Common British Oak. Peduncled 
British Oak. English Oak. Naval Oak. Longlived Oak. 
Spec. Char. Leaves deciduous, oblong, wider towards the ex- 
tremity ; sinuses rather acute ; lobes blunt. Fruits 2 or 3 upon a 
long peduncle. Acorn oblong.

* From the Celtic quer, beautiful ; and cues, a tree. It produced the Misseltoe 
of the Druids, and was thence called also derw ; hence drus, in Greek, and 
Dryades. Hooker. + See folio 93, note t. 
i Kubur, strength ; in allusion to the quality of the wood.
