upright, very fmooth, round, without knots. Leaves 
of a bright green, with the middle part of a more glau¬ 
cous appearance than the reft. Flowers pale red, (lightly 
tinged with blueifti, and fometimes yellowifli. The 
Angular motion with which the lateral leaflets or ap- 
pendicles of this plant are endued is thus defcribed in 
Linnaeus’s Supplement. “ This, is a wonderful plant on 
account of its voluntary motion, which is not occafioned 
by any touch, irritation, or movement in the air, as in 
Mimofa, Oxalis, and Dionaea ; nor is it fo evanefcent as 
in Amorpha. No fooner had the plants raifed from feed 
acquired their ternate leaves, than they began to be in 
motion this way and that; this movement did not ceafe 
during the whole courfe of their vegetation, nor were 
they obfervant of any time, order, or direction ; one 
leaflet frequently revolved, whiilft the other on the fame 
petiole was quiefcent; fometimes a few leaflets only 
were in motion, then almoft all of them would be in 
movement at once ; the whole plant was very feldoih 
agitated, and that 'only during,the firft year. It con¬ 
tinued to move in the ftove during the lecond year of 
its growth, and was not at reft even in winter.” Swartz 
obferves that the motion is irregular, and that it fome- 
times ceafes entirely; that in a very hot day it is im¬ 
movable, being agitated only in the evening, and that 
(lowly. In our climate the leaves in general only make 
a faint and feeble attempt towards the middle of the day 
at exerting their extraordinary faculty. We are at a 
lofs to account for this motion, which does not depend 
upon any external caufe that we can trace, and which 
we are not able to excite by any art'that we poffefs. It 
is not the adtion of;the fun’s rays, for this plant is fond 
of (hade, and the leaves revolve well on rainy days, and 
during the night; expofed to too much wind or fun, it 
is quiet. Perhaps fays Linnaeus, ■ there may be fome 
part in vegetables, as in animals,- where the caufe of 
motion refides. It is-a native of Bengal near the Ganges: 
and is called there buram chadali or burram chandali. It 
grows luxuriantly, and flowers, in the gardens at Ja¬ 
maica. It was introduced here in 1775 by Patrick 
Ruffell, M.D. and flowers in July and Auguft. 
37. Hedyfarum canefcens, or rough-leaved hedyfarum: 
leaves fcabrous underneath; ftem hifpid ; flowers ra- 
cemed, conjugate. This refembles H. Canadenfe very 
much. It is an upright hairy plant, with white flowers. 
Native of Virginia,. 
38. Hedyfarum repandum : leaves'ternate, repand- 
crenate ; racemes terminating, elongated. Stem woody, 
round, purplifh pubefcent at top. Flowers very remote, 
purple, before they open, drooping. Native of Arabia. 
39. Hedyfarum adhaerens: leaves ternate, oblong; 
racemes axillary; legumes cylindric, jointed, villofe. 
Stems weak, Ample, three-fided, fomewhat hairy. It 
may be doubted whether it be different from H. trigonum, 
No. 28. Native of the Weft Indies. 
40. Hedyfarum Marilandicum, or Maryland hedy¬ 
farum : leavesroundifti; ftem frutefcent, branched very 
much ; legumes jointed, even. Root perennial. Stems 
(everal, as thick as a fmall quill, eighteen inches or two 
(feet and upwards in height, round, (inooth, (lift, upright, 
with alternate leaves from top to bottom, like thole of 
Trifplium bituminofum, but blunter, pale underneath, 
and covered with foft hairs, efpecially on the upper and 
young leaves, which are hoary with a' Alky down. 
Flower-ftems fquarifti and roughifti, with fmall flowers 
diftant from each other in two long rows on (hort (lender 
peduncles; corolla purple fading to blue. Native of 
Virginia, Carolina, Maryland. Cultivated in Dr. She- 
rard’s garden at Eltham in Kent, in 1725 ; it flowered 
there the beginning of Oftober, 1729. 
41. Hedyfarum tortuofum, or twifted-podded hedy¬ 
farum: leaves oval-oblong, obtufe, fmoothifh ; racemes 
eredt, axillary; legumes twifted, compreffed, pubefcent. 
This fpecies grows eredt, and rifes generally to the 
height of two feet and a half or more. The leaves are 
A R U M. SO 3 
moderately large, and the ftipules are roundifti and 
broad. Flowers in fpikes thinly placed, on pedicels half 
an inch long ; corolla of a pale purple colour. It is fre¬ 
quent in the mere remote hills and inland parts of Ja¬ 
maica and Santa Cruz, alfo in Vera Cruz ; whence it 
was lent by Dr. Houftoun. It flowers here in July and 
Auguft. Vahl, who defcribes this, has another fpecies 
fent by Pflug from the fame ifland of Santa Cruz, which 
he calls II. molle. It refembles the tortuofum, but has 
a (Longer ftem, with larger leaves, foftly villofe under¬ 
neath, the younger ones on both fides, not at all fpotted. 
42. Hedyfarum fpirale, or fpiral-podded hedyfarum : 
leaves ovate, obtufe, fmooth ; ftem very much branched, 
with diffufed branches ; racemes loofe, divaricate ; le¬ 
gumes fpirally twifted. Stems woody, trailing, a foot 
and half long; fending out feveral branches on each (ide. 
Leaflets fmall, pale green ; flowers fmall, of a pale pur- 
pli(h colour. Annual. Native of Jamaica. 
43. Hedyfarum frutefcens .- leaves fubovate, villofe 
underneath; ftem frutefcent. Root perennial. Stems 
two or three, (hrubby, hairy, near two feet high, branch¬ 
ing on every fide near the top. Flowers at the ends of 
the branches in (hort fpikes, purplifh-yellow and fmall. 
It was fent by Dr. Dale from South Carolina. Jac- 
quin’s H. frutefcens is probably a different plant. 
44. Hedyfarum axillare : leaves rhombed-roundifit ; 
ftem creeping, rooting; petioles upright; fcapes axil¬ 
lary longer than the leaves. This runs many feet from 
the main roots, commonly cafting a few fibres from all 
the joints that touch the ground, which greatly forwards 
its luxuriant growth. The leaves are marked with fome 
prominent veins on the under fide, -and are feldom lefs 
than an inch and half in length. Common in the (liady 
hills of Jamaica and St. Domingo. 
45. Hedyfarum viridiflorum, or gi%en-flowered hedy¬ 
farum: leaves (harpifti; ftem upright; racemes very 
long, upright. Native of North America ; introduced 
in 1787, by Thomas Walter, efq. Perenpial. 
46. Hedyfarum hirtum: leaves oval ; ftem (hrubby;. 
fpikes oblong ; calyxes and fruits hirfute, one-feeded. 
In gardens, the firft year it bears mutilated flowers, and 
yet is fruitful; the fecond year the corollas are white. 
Native of Virginia. 
47. Hedyfarum junceum, or (lender-branched hedy¬ 
farum: leaves lanceolate ; legumes one-jointed, rhornb- 
(haped ; peduncles fubumbelled, lateral. Root peren¬ 
nial. Stem herbaceous, two feet high, ruftiy, wand¬ 
like, round, fomewhat furrowed, fmooth, fomewhat pu¬ 
befcent towards the end ; branches of the fame length 
and ftrudture with the ftem ; alternate, few. When the 
plant firft grows up in the fpring, the ftems are more pu¬ 
befcent, in greater number, more Ample, purple and al¬ 
moft blood-red; in the fummer they are green ; the 
lower leaves are fimple, not ternate, and purplilh. Na¬ 
tive of India. Linnseus received the feeds from David 
van Roydn in 1761; it was introduced here in 1776, by 
Monf. Thouin; and flowers in July and Auguft. 
48. Hedyfarum violaceum, or violet-flowered hedy¬ 
farum : leaves ovate; flowers in pairs ; legumes naked, 
veined, jointed, rhomb-fhaped. Flowers violet-colour¬ 
ed, in pairs, ufually conriedted by their proper pedicels, 
in fome glomerate from the axils of the leaves, in others 
fixed here and there'on filiform peduncles. Legumes 
three times as long as the calyx, (harp, fmooth, netted, 
containing one feed. Native of North America ; intro¬ 
duced in 1787, by Thomas Walter, efq.

leaves linear-lanceolate; flowers pamcled; legumes 
rhomb-fhaped. 50. Hedyfarum nudiflorum, or naked- 
flowered hedyfarum : flowering ftem naked ; leafy ftem 
angular. Flowers purple. Native of Virginia. 
51, Hedyfarum repens, or creeping hedyiarum : leaves 
obcordate ; ftems procumbent; racemes lateral. Clay¬ 
ton defcribes the American plant to have procumbent 
woody Items ; fmooth leaves; flowers, variegated red
