I P O M CE A, 
a very great length, covering fometimes many trees, or 
the banks of rivers for many paces, having a round and 
reddifh (talk, armed with blunt, herbaceous, fliort, vari- 
oufly-fhaped, prickles; and winding itfelf about any thing 
it comes near, or creeping along the furface of the ground. 
At unequal diftances come out, on petioles fix inches 
long, fmooth petioled leaves, four inches long, and as 
broad from ear to ear at the bafe, there being a finus or 
hollow from the ears to the point. The flowers are axil¬ 
lary, many, on peduncles an inch long; the tube of the 
corolla is feldom lei's than from three to four inches in 
length; the border is white, five inches in diameter, a lit¬ 
tle flnuated, and has five green ftreaks on the outfide. 
Browne obferves that the leaves of this plant, and indeed 
of all the fpecies both of convolvulus and ipomcea, are 
very variable, being fometimes in the form of a heart, and 
fometimes lobed, or panduriform ; fometimes alfo the ftem 
only is prickly, fometimes both ftem and petioles. Gsert- 
ner defcribes the fruit not as a capfule, but as a juicelefs 
berry, globular, one-celled, rufefcent or black, fmooth ; 
rind leathery, when ripe feparating from the pulp, within 
covered by a very fine white membrane, and marked with 
fix longitudinal lfreaks; pulp fungofe, fnowy-white, thin, 
perforated by filiform nutritious veflels, fo clofelj' adher¬ 
ing to the feeds, that it may be feparated along with them 
into four parts. He refers the other fpecies of Ipomcea 
(except his Zeylanica) to the genus Convolvulus, becaufe 
they have a genuine capfule, feparable into valves. Na¬ 
tive of the Weft Indies; introduced in 1773, by John earl 
of Bute ; flowers here in July and Auguft. 
11. Ipomoea campanulata, or bell-flowered ipomcea: 
leaves cordate, peduncles many-flowered ; outer perianth, 
orbicular 3 corollas bell-fhaped, lobed. Native of the Eali 
Indies.. 
12. Ipomcea violacea, or purple-flowered, ipomoea : 
leaves cordate, quite entire; flowers crowded, corollas un¬ 
divided. The round green farments or ftalks of this plant 
mount about any tree, flmtb, or hedge, to the height of 
ten or twelve feet, clothing them green with their many 
branches and leaves; thefe are two inches and a half long, 
and two inches broad, at the round bafe from one ear to 
the other, fmooth, yellowifli green, on petioles an inch 
and a quarter in length. Flowers pale purple, (blue, with 
their brims not angular, but entire, Miller-,') very large, 
bell-fhaped. Capfule brown, having above five valves, 
four round protuberances, and in each of them a large 
triangular fmooth folid whitifh-brown feed. Thefe divi- 
fions of the capfule are probably not natural, but the ef- 
fefl of luxuriance. Native of the Weft Indies. 
13. Ipomcea verticillata, or whorl-flowered ipomcea: 
leaves cordate, peduncles axillary in threes, reflex; calyxes 
hifpid. Stem feeming to be decumbent, fiexuofe, half a 
foot high, branched at the bafe, having hairs fcattered 
over it, few in number below, but more abundant above. 
Leaves petioled, an inch long, bluntifli, with a fliort dag¬ 
ger point, veined, with a few hairs on the veins under¬ 
neath; when more advanced, fmoother. 
14. Ipomcea carnea, or flefh-coloured-flowered ipomcea : 
leaves cordate, fmooth, peduncles many-flowered; corol¬ 
las margined. Stem fhrubby, in open places aimoft up¬ 
right, and fupporting itfelf to the height of a man, but in 
woods climbing twenty feet high ; the whole plant, ex¬ 
cept the feeds, very fmooth. Bark afti-coloured. The 
younger green branches are adorned with leaves, which are 
roundifh-cordate, acuminate or blunt, with a fmali point, 
quite entire, veined, alternate, fometimes eight inches in 
length and breadth, on petioles three inches long. Flowers 
elegant, but void of fmell, three inches in diameter, flefh- 
coloured, opening in fucceflion. Capfules brown and 
fliining, containing blackifh feeds wrapped up in abun¬ 
dance of brown-afh-coloured wool. This plant, having 
many things in common with Convolvulus, might not 
■unaptly be referred to that genus ; but in truth there are 
110 conftant limits between them. Found by Jacquin 
about Carthagena in America, in fandy coppices near the 
coaft; flovyering in February and March. It grew from 
feed to a confiderable height in the ftove of the imperial 
garden at Vienna, but periflied without bearing feed. 
15. Ipomoea repanda, or repand-leaved ipomcea: leaves 
cordate, oblong, repand ; peduncles branched in cymes. 
Native of Martinico, in coppices on the hills near the town 
of St. Frangois ; flowering in December and January. 
16. Ipomoea filiforrnis, or filiform ipomoea: leaves cor* 
date, blunt, with a point quite entire ; peduncles in ra¬ 
cemes filiform. The whole plant is very fmooth, with 
round twining ftems climbing up flirubs to the height of 
ten feet. Native of woods in Martinico, efpecially on the 
borders of the fait marlhes 5 flowering from November to 
January. 
17. Ipomcea haftata, or halbert-leaved ipomcea : leaves 
fagittate-haftate; peduncles two-flowered. Native of Java. 
18. Ipomcea fanguinea, or bloody-flowered ipomcea: 
leaves cordate, three-lobed ; fide-lobes angular and fub- 
lobed behind ; peduncles three-flowered, calyxes fmooth. 
Obferved in the ifland of Santa Cruz by Weft. 
19. Ipomoea glaucifolia, or glaucous ipomcea: leaves 
fagittate, truncated behind ; peduncles tvvo-fiowered. Root 
perennial. The wriiole plant is fomewhat glaucous and 
fmooth; it grows half a yard and upwards in height, with 
a (lender twining ftem. The firft leaves are oblong-cor¬ 
date, and fcarcely angular, like thofe of the fmaller field- 
convolvulus ; next they become more angular; and finally 
larger, more concave, and ftill more angular, fagittate, and 
even hnftate, fometimes cut off in a ftraight line, or trun¬ 
cate at the bafe, but generally irregular at lead on one 
fide; refembling thofe of the great wild convolvulus, or 
bind-weed. Flowers fmali, flefli-coloured or very pale 
purple, of the figure and fize of Venus’s looking-glafs, 
Convolvulus fpeculum. Native of Mexico. Cultivated 
in the Eitham garden about 1731 ; but flnce loft to the 
European ftoves. 
20. Ipomcea triloba, or three-lobed ipomoea : leaves 
three-lobed, cordate; peduncles three-flowered. Root 
annual. Stem twining, angular, ten or twelve feet high. 
Leaves three-lobed, or rather deeply trifid, aimoft equal. 
It is allied to Convolvulus edulis ; but that has the firft 
leaves undivided, the next trifid, then quinquifid, and 
fometimes even feptemfid or feven-cleft, but with the fide- 
lobes very fmali. It varies with one, two, and three, 
flowers on a peduncle ; with violet, red, and white, co¬ 
rollas, and with black and white tubers to the root. Na¬ 
tive of the Weft Indies and Japan; where it flowers from 
Auguft to October. Here it flowers in June and July. 
21. Ipomcea parviflora, or fmali-flowered ipomcea: 
leaves cordate, five-lobed, palmate ; umbels axillary, pe¬ 
riuncled ; calyxes and capfules hairy. This fpecies is al¬ 
lied to I. triloba, but feems to differ in having a fmooth 
even ftem, whereas in that it is hirfute and rugged ; five- 
lobed leaves, and peduncles commonly lix-flowered. Ac¬ 
cording to Sloane, it has a fmali ftringy root, a round 
purple (talk, two feet high, purplifh-green leaves, divided 
aimoft to the petiole, and fomewhat like thofe of the pa- 
paw ; the flowers are purple. Native of Jamaica and Santa 
Cruz. 
22. Ipomoea hederifolia, or ivy-leaved ipomcea: leaves 
three-lobed, cordate; peduncles many-flowered in racemes. 
The corolla in this is four times as long as in I. tribola, 
and the peduncles bear many flowers in racemes. It is 
an annual plant, a native of South America; introduced 
here in 1773, by Jofeph Nicholas de Jacquin, M. D. 
II. Flowers aggregate. 23. Ipomoea hepaticifolia, or 
hepatica-leaved ipomcea : leaves three-lobed, flowers ag¬ 
gregate. This rifes with a twining hairy ftalk four or 
five feet high. Native of Ceylon and Cochin-china. 
24. Ipomcea tamnifolia, or black-bryony-leaved ipo¬ 
mcea : leaves cordate, acuminate, hairy ; flowers aggre¬ 
gate. Flowers clofely heaped together in heads, and fur- 
rounded with many hairy leaves; capfules depreffed, 
rounded-four-corqered, two-celled, containing two feeds 
in each cell 5 but the principal diftinftion conflfts in the
