them may be increafed not only from feeds, but freely 
from cuttings. See Anacyclus, Anthemis, Chry¬

CO'TULA, or Cotyla , f. A liquid meafure in ufe 
among the ancients. Fannins fays, the cotyla was the 
fame thing with the hemina, which was half a fextary : 
At cotylas, quasJt placeat, dixijfe liccbit 
Hcminas recepit geminas extarias anus. 
Chorierobferves, that the cotyla was ufed as a dry mea¬ 
fure as well as a liquid one ; from the authority of Thu¬ 
cydides, who in one place mentions two cotylse of wine, 
and in another two cotylie of bread. 
COTU'Y, a canto^r and town in the Spanifh part of 
the illand of St. Domingo, bounded eaft by the bay of 
Santana, north by the chain of mountains .called Monte- 
Chrifti, weft by the territory of La Vega, and fouth by 
the chain of mountains called Sevico. In 1505, the gold¬ 
mines were worked here. In the mountain of Meymon, 
whence comes the river of the lame name, there is a cop¬ 
per-mine, fo rich, that when refined, it produce's eight per 
cent.'of gold. Here are alfo found excellent lapis-lazuli, 
a (freaked chalk, which forne painters prefer to bole for 
gilding; loadftcne, emeralds, and iron. The iron is of 
the belt quality, and might be conveyed from the chain 
of Sevico by means of the river Yuna. The foil here is 
excellent, and the plantains produced here are of Inch 
fuperior quality, that this manna of the Antilles is called 
at St. Domingo Sunday plantains. The people cultivate 
tobacco, but are chiefly employed in breeding twine. 
The inhabitants are of an unfociable character. The 
town is fituated half a league from the fouth-weft bank 
of the Yuna, which becomes unnavigable near this place, 
about thirteen leagues from its mouth in the bay of Sa- 
mana. It contains one hundred and fixty (pattered houfes, 
in the middle of a little favanna, and (unrounded, with 
woods : thirty leagues Northerly of St. Domingo, and 
fifteen fouth-eaft of St. Y.go. Lat. 19. 12. N. Ion. 72.

CO'TYLA, [from kotvA'^, a cavity. ] In anatomy, 
a cavity of a bone, in which the head of another is re¬ 
ceived. In furgery, it means a deep linus (unrounded 
with large lips. 
COTYLL'DON, f [from xorvty,' a cavity.] In bo¬ 
tany, the lobe, or placenta of the feed, deftined to nou- 
riHi the heart, and then to perilh. Corpus later ale femiiis, 
bibulum, cmucum ; the lateral body of tiie feed, bibulous 
or imbibing moifture, and caducous or falling off quick¬ 
ly. Gileke defines it to be r folium prinium germinantis fc- 
minis, but this is properly the feed-leaf. In Englifli we 
commonly call this part the cotyledon, ox feed-lobe, when 
we fpeak of it as a portion of the feed, in a quiefeent 
ftate ; and the feed-leaf, when the feed is in a growing 
(late. The greater part of feeds have two lobes ; fome 
however have more, others only one, and others have 
none. Hence a diftindtion of all plants into acotyledones, 
monocotyledones, dicotyledones, polycotyledon.es, which 
forms the bafts of Ju(lieu’s Natural Arrangement. In 
comparative anatomy, it means a glandular lubftanCe ad¬ 
hering to the chorion of many animals. 
COTYLE'DON, f [from xorvXvi, achollow.] Tn bo¬ 
tany, the herb Navel-wort ; a genus of the clafs de- 
candria, order pentagynia, natural order fucculentae. 
The generic characters are—Calyx : perianthium one- 
leafed, five-cleft, acute, very fmall. Corolla: petal 
bell-fhaped, five-cleft; nectary confifting of a concave 
fcale, leated at the exterior bafe of each germ. Sta¬ 
mina: filaments ten, fubulate, ftraight, the length of 
the corolla ; Anthene eredt, four-furrowed. Piftillum : 
germs five, oblong, thickilh, ending in fubulate (tyles, 
which are longer than the ftamens ; ftigmas (irnple. Pe- 
ricarpium: capfules five, oblong, bellied, acuminate, 
one-valved; gaping longitudinally inwards. Seeds: very 
C O T 
many, fmall.— Ejfential Char abler. Calyx ; five-cleft; co¬ 
rolla one-petalled, with five nectareous feales at the bale

Species. 1. Cotyledon Orbiculata, or round-leaved na¬ 
vel-wort : leaves ovate-fpatulate, obtufe with a point, 
even; flowers panicled. Its varieties are, a. Ov;d-leaved 
navel-wort; leaves ovate-fpatulate, Item ereCt. /?. Oblong¬ 
leaved navel-wort; leaves oblong-fpatulate, item erect. 
y. Branchingnavel-wort; leaves ovate-fpatulate, Item very 
much branched and divaricated. A Ronnd-leaveu navel- 
wort ; leaves orbiculate-fpatulate, ftem ereCt. 
This and molt of the other fpeoies are natives of the 
Cape of Good Hope. The firft fort varies much in the 
form of the leaves, &c. Some of thefe varieties are 
made diftindt fpecies, and are thus deferibed by Miller. 
y. This has a fhort thick fucculent ftalk, which rarely 
riles more than a foot high, branching out on every fide, 
fo as to fpread over the pots in which it is planted. The 
branches become woody by age, and are clofely befet by 
thick round leaves of a greyifh colour, with purple bor¬ 
ders, plane on their upper fide, but convex on their un¬ 
der, and very flefhy, of an herbaceous colour within, and 
full of moifture. A This alfo has a thick fucculent ftalk, 
which by age becomes woody, and rifes three or four 
feet high, (ending out crooked branches,- which grow ir¬ 
regular, with thick flefhy fucculent leaves about two 
inches long, and near as wide towards the top ; they are 
narrow at the bafe, and rounded at the top, of a fea-green 
colour, with a purple edge, which is frequently irregu¬ 
lar y indented ; flowers on thick fucculent peduncles, 
from the ends of the branches, near a foot long, naked, 
and fupporting eight or ten flowers, hanging down, tube 
long, brims' turning back ; ftamen and ftyles longer than 
the tube, and hanging down. They flower from July to 
September. 
2. Cotyledon fpuria, or narrow-leaved navel-wort : 
leaves fpatolate, obtufe with a point, naked. This has 
a fhort greenifh fucculent ftalk, feldom more-,than a fpan 
high, dividing into feveral irregular branches; leaves 
thick, fucculent, four inches long, half an inch broad, 
and as much in thicknefs, having a broad concave furrow 
on their upper fide, andconvex on the under bright green, 
with a purple tip ; flowers on fhort pedicels, yellow ; 
tubes long, brims reflex, tipped with purple ; (lamina 
longer than the tube. 
3. Cotyledon lpinofa, or prickly navel-wort: leaves 
oblong, fpiny-mucronate ; ftem (piked. This is a pe¬ 
rennial plant, a long (pan in height; ftem, for one-third 
part at the bottom, where it is covere'd with leaves, per- 
pe'ndicular ; the other two-thirds, which are clothed with 
flowers, bent in form of an S, thick, angular, fluff. Na¬ 
tive of Siberia, .whence it was brought to the imperial 
garden at Peterfburgh ; Mr. Miller received it from Dr. 
Anmann. It flowers in April, and fometimes bears fped 
in England. 
4. Cotyledon hemifphaerica, or thick-leaved navel- 
wort : leaves fuborbiculate dotted with feurf, convex 
underneath ; flowers fubfeilile. This has a thick fuccu¬ 
lent ftalk, rarely more than a fpan high, dividing into 
many branches ; leaves, fhort, thick, fucculent, not more 
than half an inch long, and a quarter of an inch broad, 
greyifh with green fpots. 
5. Cotyledon ferrata, or notch-leaved navel-wort : 
leaves oval, crenate ; ftem (piked. Stalk upright, fuc¬ 
culent ; flowers purplifh, in a loofe fpike. It is a bien¬ 
nial plant, and the feeds ripen in autumn. Native of 
Candia and Siberia. 
6. Cotyledon umbilicus, or common navel-wort, kid¬ 
ney-wort, or wall-pennywort : leaves peltate-crenate ; 
ftem almoft Ample ; flowers pendulous ; bracles entire. 
Of this there are two varieties:— a. Cotyledon repens, 
or yellow navel-wort: leaves peltate-crenate; ftem al¬ 
moft Ample; flowers ereft ; bracles toothed, j?. Cotyledon 
tuberofa, or common navel-wort. Mr. Hudfon has dift- 
tinguilhed the yellow from the common navel wort, by
