month ; but they grow stronger where this is 

 avouled, by placing them at first in larger pots, 

 and thinner in the bed, so as to have full room 

 to rise to a proper size. The frames should be 

 raised as the plants advance in growth. 



About the beginning of June they should be 

 gradually exposed to the influenee of the full 

 air, in order to harden them, that they may be 

 set out towards the end of it ; when they should 

 have sticks placed for their support, to which 

 they should be neatly tied. The potted plants 

 should likewise be often refreshed with water, 

 once or more in the day, when the season is 

 hot. Those in the open ground should also be 

 occasionally watered in dry weather. See An- 

 nual Plants. 



All these plants may be raised with ^rcat fa- 

 -cility in the stove, in the same manner as above. 



In the second species the seed may be sown 

 either early in the spring, or in the autumn. In 

 both the species those in the natmal ground 

 should be sown later than in the hot-bed me- 

 thod. 



In order to save seed, a few of the best 

 plants, of the diflerent finest varieties, should be 

 placed, when in full blow, in some airy situation, 

 60 as to be exposed to the sun, and at the same 

 time protected from wet by glasses. 



The fine potted species and varieties of these 

 plants are highly ornamental among other 

 potted plants, in the most conspicuous places 

 about the houses ; and the less valuable kinds 

 in the fronts of the borders, clumps, and other 

 parts of pleasure-grounds, in mixture with other 

 flowery plants.

The species cultivated are : 1 . /. tiuctoria. 

 Dyer's Indigo; 2. /. argoilea, Silvery-leaved 

 Indigo; 3. I. candicans, \y\-ii\.& Indigo; 4. /. 

 amocna, Scarlet-flowered Indigo. 



Tlie first has the stem filiform, subflexuose, 

 angular, smooth, upright, a foot and half high, 

 a little branched at top : the branches like the 

 stem, alternate, upright: the leaflets in fowr 

 pairs or more, very blunt with a point, smooth, 

 very finely villose underneath, almost equal : 

 the racemes from the axils of the leaves, when 

 they begin to flower, nmch shorter than the leaf, 

 but becoming longer as they advance : the le- 

 gumes drooping, subcolumnar, sharp, straight, 

 very finely villose. It is a native of the East 

 Indies. 



The second species has the whole plant silky 

 and glaucous : the stem sufTruticose, upright, 

 branched, round, from half a yard to three 

 quarters of a yard in height, and gray: branches 

 alternate, stiff, round, finely silky, and hoary : 

 the leaves alternate, petioled, two-paired (seldom 

 ternate), spreading, three inches long : leaflets 

 opposite, subsessile (the end one larger and pe- 

 tioledj, quite entire, bluntish, the older ones 

 subemarginate, the midrib raised only under- 

 neath, finely silky, glaucous, spreading, flat,
