Wales, in Sion Gardens, belonging to his grace the duke 
of Northumberland; and it flowered there in 1790. it 
produced ripe pods and perfect feeds in the dove of Chel- 
l'ea-garden, in May 1795; but in the greenhoufe the 
• flowers go off without any tendency to produce fruit. It 
is a fnrub of quick growth, and a ready blower. 
84. Mimofa fuaveolens, or fw'eet-feented mimofa : leaves 
linear, acuminate, ftraight, cartilaginous at the edge, the 
primordial ones pinnate; branches triquetrous. The 
branches of this are molt acutely triangular, and much 
compreifed; their edges bright red. Leaves alternate, 
four or five inches long, with a rib and margin like the 
laft. Flowers in axillary racemes, yellowifh-white, fra¬ 
grant. This fpecies and the preceding belong to the firlt 
divifion of this genus, for the knowledge of which we 
are indebted to the fouthern hemifphere. In their adult 
date they have leaves totally different from thole which 
they produce at their firlt Springing out of the ground, 
as defcribed in the preceding fpecies. This allb flowered 
in Sion Gardens under the care of Mr. Hoy, in the year 
1790, from feeds brought from New South Wales. 
85. Mimofa hilpidula, or little harfh mimofa: leaves 
elliptical, oblique, rugged on each fide and at the mar¬ 
gin ; branches hifpid-pubefcent; heads folitary. This 
forms a thick rigid bufh. Branches numerous, alternate, 
lpreading, round, very rough with a fhort denfe rigid 
pubefcence, elpecially when young. Mowers pale yellow, 
many together, in little round heads. It is an inhabi¬ 
tant of Port Jackfon in New South Wales, and the living 
plant has not yet been introduced. 
86 . Mimofa microphylla, or prickly red mimofa: prickly 
all over ; leaves bipinnate eight-paired ; leaflets fixteen- 
paired ; heads axillary, peduncled, folitary, or in pairs. 
Native of Georgia and Carolina. 
IX. From Vahl’s fecond part of Symbols: Botanicae. 
87. Mimofa mellifera, or honeyed mimofa: thorny; leaves 
bigeminate, blunt; prickles recurved. In the fhape of 
the leaves this refembles M. unguis cati, but they are 
only one-fifth of the fize. Native of Egypt. 
88. Mimofa nit id a, or fliining mimofa: thorny; leaves 
bipinnate, two-paired, a gland between each ; leaflets 
five-paired ; fpikes globular, peduncled. Branches round, 
purple, flexuofe, pubefccnt. Leaves remote, on very fhort 
petioles, very fmooth, an inch and a half long. Flowers 
eight or ten in each head. Found by Koenig in the 
Ea$ Indies. 
89. Mimofa umbellata, or umbelled mimofa: thorny; 
leaves conjugate and bipinnate, two-paired; flowers um¬ 
belled ; legumes fpiral. This is a tree, with round fmooth 
dotted branches, and fhort flexuofe remote tubercled 
wrinkled branchlets. Leaves on the branches remote, 
alternate; on the branchlets approximating, luboppofite 
or terminating. Found in Ceylon by Koenig. 
90. Mimofa afak, or purple mimola: fpines in threes, 
ftraight; leaves bipinnate, three-paired, proper five-paired, 
a giand between the lowed pair of the partial ones. 
Branches purple, fmooth, flexuofe. It differs from M. 
Senegal by its purple branches, llraight fpines, and few- 
nefs of pairs to the leaves: in that, the leaves are many- 
paired and wider, and the petiole is terminated by a re¬ 
curved prickle. Native of Arabia. 
Propagation and Culture. Thefe plants are all capable 
of being increafed by feed, and fome of the fenfitive kinds 
by layers and cuttings; but the firft is by much the beft 
method. The feed procured from the nurferies or feed- 
fhops fhould be fown in pots of light rich mould early in 
the fpring, covering it with fine earth, a quarter of an inch 
deep, and plunging the pots in the hot-bed ; if in a com¬ 
mon hot-bed under frames dnd,glaffes, managing them 
nearly in the manner of tender annuals; and, when in a 
bark-bed in the ftove, little trouble is required. But mo¬ 
derate fprinklings of water fhould be given ; and, when 
the plants are two or three inches high, they fhould be 
planted out fingiy into fniall pots, prelerving tire earth 
6 S A. 
to their roots, replunging them in the hot-bed, See. giving 
water and occafional (hade till they are well rooted, re¬ 
peating the waterings frequently. The plants fhould af¬ 
terwards be continued in the hot-bed under glaffes, or 
plunged in the bark-bed of the ftove, to facilitate their 
growth, preferve them in vigour, and increafe the fenlir 
bility of the fenfitive kinds; admitting frefh air pretty 
freely. It is proper that the perennial forte, both flirubby 
and herbaceous, fhould be kept in the ftove all winter, 
and principally the year round. And they muft be fre¬ 
quently removed into larger pots to prevent the roots 
from getting through the pots, which they are apt to do, 
and by that means are often deftroyed. 
The acacia kinds are the moft tender, requiring the 
ftove almoft conftantly, except a little in the heat of fum- 
mer, when they muft be placed in a warm fituation. They 
fhould always have a bark hot-bed, and v be put in very 
fmall pots filled with fandy mould, the heat of the ftove 
being kept up to above temperate : as the leaves of fome 
of them are filed, they have the appearance of being dried 
when that is not the cafe. 
Where there is not the convenience of a ftove, thole 
who are curious to have the plants, may have them in 
fummer, by, the aid of a common dung or tan-bark hot¬ 
bed, under frames and glaffes, though not in winter; by 
railing fome of the annual or any of the other kinds, by 
feed in fpring, in a hot-bed under a frame, Sec. keeping 
up the heat of the bed until the middle of June, and con¬ 
tinuing the plants always under the frame, raifing one 
end of the lights a little, occafionally, in warm days, to 
admit frefh air; and, as they rife in height, raife the fram* 
at the bottom, to allow them full room to grow. About 
midfummer, or foon after, lome of the low fpreading kinds 
may likewife be turned out with balls, or plunged in 
their pots into a w'arm funny border, and covered with 
large hand-glafles, which may be lifted off occafionally 
juft to view the plants. By thefe methods, the plants 
may be prelerved through the fummer in their fenfitive 
quality, though not in equal perfedlion to thofe in 
ftoves ; nor can they be preferved alive in winter out of 
the ftove. 
The fenfitive forts often branch out profufely, fo as to 
furnilli plenty of young flioots for cuttings, which fhould 
be planted in pots in the fummer feafon, plunging them 
in the bark-bed, whereby they often readily take root, 
and form good plants. Thefe modes fhould, however, 
only be p radii fed when feed cannot be procured. 
The horned acacias are very often deftitute of leaves 
for two or three months, appearing to have no life ; but 
they will put out frefh leaves towards autumn, which is 
commonly the feafon when they are moft vigorous. Thefe 
fhould be expofed in the fummer-feafon for about two 
months, to clear them from infedts, which greatly infeit 
them, in a place defended from ftrong winds; and in the 
winter they require a moderate degree of warmth. All 
the other forts here mentioned are propagated by feeds, 
which, feldom ripening in this country, muft be procured 
from America, particularly at Campeachy, where there is 
great variety of this tree, many lortsxof which have been 
hitherto unknown to botanical writers. In bringing over 
the feeds of thefe trees, they fhould be taken out of the 
pods when gathered, and put up in papers, and ought 
to have tobacco, or fome other noxious herb, put between 
the papers, to keep off infedts, othenvife the feeds will 
be eaten and deftroyed before they arrive in England. 
For the infedts depoiit their eggs in fmall punctures 
which they make in the pods ; and, as thefe are foon 
hatched, fo they immediately attack the feeds for food, 
and eat holes through them, by which they are hindered 
from growing. 
The general culture of all the fpecies is afterwards to 
keep them always in pots placed in the ftove, being 
plunged occafionally in the bark-bed, elpecially the 
fpreading fenfitive kinds, frequent waterings being given 
in fummer and winter, but confiderably the moft in the 
fummer
