LXXXVI. CUPULIFEEiE.

Cory l us. ~\ 
Woods in the S. and S.W. of England. k ■ 5 — 7. — This noble 
tree is much cultivated in plantations on account of its timber. Usually 
the sterile flower has the perianth G-cleft; the fertile 12 rudimentary 
stamens, 6 styles, and a 6 -celled ovary. 
3. Quebcus Linn. Oak. 
Barren jl. in a lax catkin or spiltc , without scales. Perianth 
single, 5 — 7-cleft. Stamens 5 — 10. Anthers 2-celled. — Fertile 
jl. aggregate or in a lax spike. Involucre 1 -flowered, of many 
little scales united into a cup. Perianth single, closely investing 
the ovary, 6-toothed. Ovary usually 3-celled. Style short. 
Stigmas usually 3, oblong, compressed. Nut (or acorn ) solitary, 
surrounded at the base by the enlarged cup-shaped indurated 
involucre. — Named, according to Lepelletier, from the Celtic 
quer, beautiful, and cuez, a tree; a term perhaps given to those 
few oaks on which the mistletoe was found : but the proper 
Celtic name was derw ; hence clarach, Gaelic ; Spvg, in Greek, 
and dryades, as well as druids. 
1. Q. Bobur L. (common British O .) ; leaves deciduous oblong- 
obovate deeply sinuate, their lobes obtuse, fruits aggregate in 
the axils of the uppermost leaves or along an axillary stalk, 
involucre 3 — 4 times shorter than the mature nut its scales 
oblong obtuse closely imbricate. — «. fruits 2 — 6 in a long- 
stalked spike. E. B. t. 1342. Q. pedunculata Willd. — id- 
fruits aggregate or on a rather shortly stalked spike. Q. ses- 
siliflora Salisb.: E. B. t. 1845. Q. Robur Willd. Q. inter- 
media D. Don. 
Woods and hedges, not uncommon, particularly in the Highlands 
of Scotland, h • 4, 5. — Dr. Greville ( Trans. Dot. Soc. Erl. i. p. 65, 
t. 4, 5) has shown that there is no connexion whatever between the 
relative length of the fruit-stalk and the petiole. The flowers are 
sessile upon the peduncle in both varieties ; but in /3. the peduncle is 
mostly very short, or almost wanting, in a. much elongated : between 
these there is every gradation. Q. intermedia is said to have the lobes 
of the leaves separated by obtuse angles, and the Q. Robur and Q. 
sessitiflora by acute angles ; but both kinds may be observed on the 
same branch, and sometimes on the same leaf. The word Robur is 
derived from rove, another Celtic word for the oak ; whence arises 
robur, strength, in Latin. 
4. Cobylus Linn. Hazel-nut. 
Barren flowers in a cylindrical catkin; its scales 3-cleft, 
middle lobe covering the two lateral ones. Perianth 0, except 
the two inner collateral scales of the catkin which cohere at their 
base to the outer one (or true scale). Siam. 8. Anthers 1 -celled. 
— Fertile jl. 1 — 2 together within a minute involucre of 2 — 3 
cohering laciniate hairy scales, the whole collected into a short 
gemmaceous bracteate catkin. Perianth closely investing the
