INDIGOF'ER A, J [Lat. bearing or yielding the blue 
dye called indigo, or indicum; from its native country 
India.] Indigo ; in botany, a genus of the clafs diadel- 
phia, order decandria, natural order of papilionaceas or le- 
„ guminofte. The generic characters are—Calyx: perian- 
thium one-leafed, fpreading, nearly flat, five-toothed. 
Corolla: papilionaceous; ftandard rounded, reflex, emar- 
ginate, fpreading ; wings oblong, obtufe, fpreading at the 
inferior margin, of the fhape of the ftandard; keel obtufe, 
fpreading, deflex, marked -on each fide by an awl-fhaped 
hollow dagger or point. Stamina: filaments diadelphous, 
difpofed in a cylinder, afeending at their tips ; anthers 
roundifh. Piftillum : germ cylindric ; ftyle Ihort, afeend¬ 
ing ; ftigma obtufe. Pericarpium : legume roundifli, 
lone; (linear-oblong, commonly four-cornered. Gartner.) 
Seeds: fomekidney-fhaped; (kidney-retufe or cuboid. G.) 
—EJential CharaEler. Calyx fpreading ; keel of the co¬ 
rolla with an awl-fliaped fpreading fpur on each fide; le¬ 
gume linear. 
At the end of the laft century it was not known in Eu¬ 
rope with certainty what plant produced the dye which 
was known to the Romans by the name of indicum, and 
Was fo much ufed as a dye, &c. under the name of indigo. 
It was cultivated, however, by Mr. Miller fo early as the 
year 1731- Only five fpecies were imperfectly known to 
Linnreus in 1763 ; and Mr. Miller has only the fame 
number in the laft edition of his Dictionary. Twenty- 
three fpecies are enumerated in the fourteenth edition of 
the Syftema Vegetabilium, by chevalier Murray; and pro- 
fefl’or Martyn has increafed the catalogue to thirty-five. 
The indigos are ftirubs, underflirubs, or herbs. The 
leaves are in fome few cafes Ample, in more ternate, in 
molt unequally pinnate, the leaflets in fome jointed and 
awned at the bafe, as in Phafeolus. The herb in moft of 
the fpecies yields a blue dye ; which, however, is not pe¬ 
culiar to this genus 5 for many plants of this natural clafs 
abound with the fame blue-colouring matter.

Species, 1. Indigofera fericea, or filky-leaved indigo: 
leaves Ample, lanceolate, Alky ; fpikes feflile; ftem fhrub- 
by. Stems determinately branched or proliferous, fili¬ 
form, rugged with fears, with leafy branchlets. Leaves 
cluftered, lhort, acute,, pubefeent; varying, with edge 
naked and coloured. See Botany Plate VI. fig. 16. vol. iii. 
Spike terminating, ovate, villofe, with braCtes the length 
of the calyxes between the flowers. Keel of the corolla 
fhorter than the other petals, dark purple, with a long 
claw, and on each Ade a fpur. Native of the Cape of 
Good Hope. 
2. Indigofera oblongifolia, or oblong-leaved indigo: 
leaves Ample, oblong, Alky; racemes axillary; ftem 
fhrubby. This is a fhrub, with tomentofe-filky branches, 
and numerous flowers. 
3. Indigofera linifolia, or flax-leaved indigo: leaves 
Ample, linear, hoary; legumes globular. Stem thort, up¬ 
right ; branches elongated, (lender, rod-like, decumbent, 
angular, finely villole. Flowers three or four, on ftiort 
pedicels in the axils of the leaves, red. Fruit globular, 
crowned with the ftyle, fnow-white, one-feeded. Native 
of the Eaft Indies, where it was obferved by Koenig, who 
fent it to Europe together with the feeds under this name, 
though it is deferibed as a Hedyfarum by the younger 
Linnaeus in his Supplement. It has, however, the fpur on 
each fide of the keel, which determines it to be an Indi¬ 
gofera; nor has it the habit of the Hedyfarums, according 
to the remark of Vahl, who cultivated it at Copenhagen. 
4. Indigofera ovata, or ovate-leaved indigo : leaves fim- 
ple, ovate ; ftem herbaceous. This was found at the Cape 
of Good Hope by Thunberg. 
5. Indigofera fpinofa, or thorny indigo: leaves ternate, 
obovate, peduncles fpinefeent; Item fhrubby. This is'st 
fhrub with an afli-coloured bark, and very much branched. 
Native of the Eaft Indies and Arabia. 
6. Indigofera trifoliata, or trifoliate indigo: leaves ter¬ 
nate, flowers feflile, lateral, Native of the Eaft Indies. 
7. Indigofera pl'oraloides, or long-fpiked indigo : leaves 
ternate, lanceolate; racemes very long, legumes droop¬ 
ing. Stem perennial, angular, with three ribs occafioned 
by the petioles running down it, and fomewhat rugged. 
Native of the Cape of Good Hope; flowers from July to 
September. Perhaps this may be the glabra of Miller; 
which, as far as we can judge, is not the glabra of Lin¬ 
naeus. In the Amoenitates Academicae it is deferibed 
under the name of Cytifus pforaloides, as a fhrub a foot 
high, with awl-fhaped ltipules ; the leaves petioled, the 
leaflets all feflile, lanceolate, almoft naked ; fpikes pedun- 
cled, upright, calyxes pubefeent; flowers clofely reflex, 
See. &c. 
8. Indigofera candicans, or white indigo : leaves ter¬ 
nate, lanceolate-linear, Alky underneath; fpikes pedun- 
cled, few-flowered; legumes cylindric, ftraight. This 
fpecies is diftinguifhed by the whitenefs of the ftem and 
the under-fide of the leaves. The flowers are red, five to 
eight or nine in a fpike. Native of the Cape of Good 
Hope, whence it was introduced by Mr. Francis Maffon 
in 1774. It flowers from July to September; but its 
principal time of flowering, according to Mr. Curtis, is 
from the beginning of May to the middle of June. 
9. Indigofera amcena, or fcarlet-flowered indigo: leaves 
ternate, oval, fomewhat hairy; branches round,fpikes pe- 
duncled, ftipules briftle-fhaped ; calyxes loofe, ftem fru- 
tefeent. This alfo is a native of the Cape, and was intro¬ 
duced by the fame perfon at the fame time. It flowers in 
March and April. 
10. Indigofera procumbens, or proftrate indigo: leaves 
ternate, obovate; ftem herbaceous, proftrate; fpikes pe- 
duncled. Stem a foot long, fomewhat angular, almoft 
naked. Flowers dark purple. Native of the Cape of 
Good Hope. 
11. Indigofera farmentofa, or dwarf indigo : leaves ter¬ 
nate, ovate, fubfeflile; peduncles axillary, two-flowered 
or thereabouts; ftem proftrate, filiform. This was found 
at the Cape by Thunberg; and alfo by Maffon, who in¬ 
troduced it at Kew in 1786, It flowers in June.
