ftalk ; they are of a flefti colour, and fpread open 
like thofe of the Auricula. It flowers in April, but doth' 
not produce feeds in the gardens, for this plant is 
with great difficulty kept in a garden. The only 
method by which I could ever preferve it, has been 
by planting the plants in pots, and placing them in 
a fhady fituation, where they were duly watered in 
dry weather ; in this place they conftantly remained 
both fummer and winter, for the cold will not deftfoy 
them •, the earth for this plant fhould be light, and 
not too rich, for dung is very injurious, to it. As 
this very rarely produces any feeds in England, the 
only method to propagate it is, by parting the roots 
in the fame manner as is practifed for Auriculas ; the 
beft time for this is about Michaelmas, foon after 
which the leaves decay. 
The fecond fort is very like the firft, but the flowers 
are much lefs, and their empalements are larger •, this 
grows naturally in Siberia, but is with great difficulty 
kept in a garden. 
CORYLUS. Lin. Gen. Plant. 953. Tourn. Inft. R. 
H. 581. [fo called from Gr. a Hazel, or 
Filbert-tree. It is alfo called Avellana, from Avella, 
a town in Campania, wffere it grew in great plenty.] 
The Hazel, or Nut-tree. 
The Characters are, 
It hath male and female flowers growing at remote dif- 
iances on the fame tree. The male flowers are produced 
in long fcaly katkins , each fcale including a Jingle flower , 
having no petals , hut eight fhort ftamina faflened to the 
fide of the fcale? and terminated by oblong erect fummits. 
‘The female flowers are included in the future bud , fitting 
clofe to the branches ; thefe have a thick two-leaved peri- 
anthium , torn on the border , fitting under the flower 
when it is fmall, but afterward is enlarged to the fize of 
the fruit ; it hath no petal but a fmall round germen 
occupies the center , fupporting two briftly coloured flyles, 
which are longer than the empalements crowned by two 
fingle ftigmas. The germen afterward becomes an oval 
■nuts paved at the bafe , and comprejfed at the tops ending 
in a point. 
This genus of plants is ranged in the eighth febtion 
of Linnaeus’s twenty-firft dais, intitled Monoecia Po- 
lyandria, from there being male and female flowers 
• on the fame plant, and the male flowers having many 
ftamina. 
The Species are, 
1. Corylus ( Avellana ) ftipulis ovatis obtufis. Llort. 
Cliff. 44.8. Hazel Nut with oval blunt ft ip nice. Cory- 
lus Sylveftris. C. B. P. 418. Wild Hazel Nut. 
2. Corylus ( Maxima ) flipulis oblongis, obtufis, ramis 
erebrioribus. Hazel with oblong blunt ftipulte, and the 
branches growing more erebl. Corylus fativa frubtu ob- 
longo. C. B. P. 418. The Filbert. 
j. Corylus ( Column ) flipulis linearibus acutis. Hort. 
Cliff. 448. Hazel with narrow acute ftipula. Corylus 
Bvzantina. H. L. 19 1. Byzantine Nut. 
The firft of thefe trees is common in many woods in 
England, from whence the, fruit is gathered in plenty, 
and brought to the London, markets by the country 
people. This tree is feldom planted in gardens (ex- 
cept by perfons curious in collebtions of trees and 
fhrubs -,) it delights to grow on a moift ftrong foil, 
and may be plentifully increafed by fuckers from the 
old plants, or by laying down their branches, which, 
in one year’s time, will take fufficient root for tranf- 
planting; and thefe will be much handfoiner and better 
rooted plants than fuckers, and will greatly outgrow 
them, efpeciaily while young. 
There is a variety of this with fruit growing in great 
clufters at the end of the branches, which is diftin- 
guifhed by the title of Clufler Nut-, but as this is 
iuppofed to be only a variety, which accidentally 
came from the other, I have not diftinguifhed it ; 
however, this may be continued by layers, fo the kind 
may always be preferved. 
The fecond fort is by many fuppofed to be only a fe- 
minal variety from the firft, which hath been im- 
proved by culture -, but this is very doubtful, for I 
'Lave feveral times propagated both from the nuts, 
but never have found them vary from cnb to tk§ 
other, though they have altered in the fize and co- 
lour of their fruit, from the forts which were fowti % 
but as the fhrubs of this grow more erebt than thofe 
of the other, and the ftipulm are different in their 
fliape, fo I have enumerated it as a diftinbt fort \ of 
this tiiere are the red and white Filberts, both which, 
are fo well known, as to need no defcription. 
The third fort grows naturally near Conftantinopie * 
the nuts of this are large; roundilli, and in fhape like 
thofe of the common Hazel, but are more than twice 
their fize. The cups in which the nuts grow are 
very large, fo as almoft to cover the nut, and is deeply 
cut at the brim. This fort is not common in England, 
but I take thofe large nuts which are annually im- 
ported from Barcelona in Spain, to be of the fame 
kind, the nuts being fo alike, as not to be diftin- 
guifhed when out of their cupT; and thofe of the 
Spaniflh fort come over naked, fo I cannot with cer- 
tainty fay how they eftentially differ. 
All thefe forts may be propagated by fowing their 
nuts in February; which, in order to preferve them 
good, lhould be kept in land in a moift cellar, where 
the vermin cannot come at them to cleftroy them 
nor fhould the external air be excluded from them* 
which would occafion their growing mouldy. 
The manner of fowing the feeds being well kndwri 
to every one, I need not here mention it, efpeciaily 
fince it is not the fureft -way to obtain the forts de- 
fired ; for they feldom prove fo good as the nuts 
which were fown, or at leaft not one in four of them 
will ; and the method of propagating them by layers 
being not only the fureft, but alfo moft expeditious, 
is what I would recommend to every one who 
would cultivate thefe trees for the fake of their fruits. 
CORYMBIFEROUS PLANTS are fuch as 
have a compound difcous flower, but their feeds 
have no down adhering to them. The name is taker! 
from the manner of bearing its flowers in ciufters, 
and fpreading round in the form of an umbrella, Of 
this kind is the Corn Marigold, common Ox Eye, 
the Daify, Camomile, Mugwort, Feverfew, &c. 
Mr. Ray diftinguiflies them into fuch as have a ra- 
diated flower, as the Sun Flower, Marigold, &c. and 
fuch as have a naked flower, as the Lavender Cotton 
and T anfey, and alfo thofe that are akin to them, as 
Scabious, Teafel, Carduus, &c. 
CORYMBIUM. 
The Characters are, 
It hath an empalement of two leaves, having fix angles §' 
the fmall leaves are ere dl and clofe together their whole 
length, and are triangidar on their outfides cut into three 
fegments, and are permanent. The flower has one petal, \ 
which is equal, having a very port tubes cut into five 
fegments at the brims which fpread open-, it hath five 
creel ftamina fitting within the tube , crowned with oblong 
creel fummits, porter than the petal, joining in a cylin- 
der : the germen is fituated within the empalement , at 
the bottom of the petal, fupporting a fingle erect ftyle the 
length of the petal, terminated by a bifid oblong ftigma % 
the germen afterward becomes an oblong feed , having a 
fort of doivn adhering to it. 
This genus of plants is ranged in the fixth febtion of 
Linnaeus’s nineteenth clafs, intitled Syngenefia Mo- 
nogamia, the flower having five ftamina which join 
by their fummits, and is fucceeded by one feed. 
We know but one Species of this genus, viz. 
CoPvYmbium ( Africanum ), Hort. Cliff. 494. African Co - 
rymbium. Bupleurifolia femine pappofo, valerianoides 
umbellata, cauliculi fcabro. Pluk. Aim. 79. 
This plant grows naturally at the Cape of Good 
Hope ; it rifes with an erebt rough ftalk about a 
foot high, with a fingle leaf at each joint, which half 
embrace the ftalk with their bafe. The leaves ar® 
long, narrow, and triangular, and have a downy fub- 
ftance intermixed with them at their bafe ; the upper 
part of the ftalk divides into feveral foot-ftalks, 
which are terminated by purple flowers of one petal, 
cut into five parts at the brim, each being fucceeded 
by an oblong feed.
