INDIGOFERA 655 



I. GERARDIANA, Wallich. 



(I. Dosua, Lindley, in Bot. Reg. 28, t. 57 not Hamilton?, 



A deciduous shrub with downy, slightly-ribbed branches. At Kew, where 

 it is almost invariably cut back to the ground each winter, it sends up a dense 

 thicket of erect, scarcely branched shoots 2 to 4 ft. high, clothed from top to 

 bottom with leaves. Where the climate is milder the shoots survive, and it 

 then becomes a much-branched shrub, perhaps 6 or 8 ft. high. On a wall at 

 Kew it is 10 ft. high. Leaves pinnate, 2 to 4 ins. long, composed of six to 

 ten pairs of leaflets and an odd one ; leaflets to f in. long, obovate or oval, 

 clothed with grey appressed hairs on both sides, the apex notched or rounded 

 and having a short bristle-like tip. Racemes produced from the leaf-axils in 

 succession from below upwards, on the terminal part of the shoot. They are 

 3 to 5 ins. long, bearing short-stalked, pea-shaped flowers \ in. long, rosy 

 purple, two dozen or more on each raceme. Calyx downy, with lance-shaped 

 lobes. Pod deflexed when ripe, i to 2 ins. long, in. wide, cylindric, six- to 

 ten-seeded. 



Native of the north-western Himalaya. Commencing to blossom about 

 the end of June, and continuing until the end of September, having also 

 foliage of great beauty and luxuriance, this is one of the most ornamental of 

 late-flowering shrubs. It has the disadvantage of starting late into growth, and 

 it is not until June that the stools become well furnished. For this reason 

 it is not suitable for planting alone in masses. It likes abundant sunshine, 

 and does not flower so freely in dull seasons. 



I. HEBEPETALA, Bentham. 



(Bot. Mag., t. 8208.) 



A deciduous shrub, growing about 4 ft. high at Kew, but considerably 

 taller where it is not cut back during winter ; stems smooth, except when 

 quite young. Leaves pinnate, 7 to 9 ins. fong, with usually seven to nine 

 (occasionally eleven) leaflets, which are oblong, broadly oval or slightly 

 ovate, short-stalked ; I to 2^ ins. long, half as much wide ; rounded or notched 

 at the apex, smooth above, the appressed hairs beneath attached by their 

 middle. Racemes 3 to 9 ins. long, produced from the leaf-axils of the 

 terminal part of the shoot, and developing in succession as it lengthens: 

 Flowers closely set, twenty to sixty on one raceme, each \ to $ in. long, 

 the standard petal crimson, wing and keel petals rose-cofoured. Pod \\ 

 to 2 ins. long, cylindric, smooth, carrying eight to ten seeds. 



Native of the north-western Himalaya, where it is widely spread at 

 altitudes of 6000 to 8000 ft. It is strange that so handsome a shrub should 

 be so little known in gardens. The date of its introduction is not recorded, 

 but it has been cultivated at Kew since 1881, when it came with a collection 

 of plants bequeathed by Mr J. C. Joad, a well-known amateur of his time. 

 It produces its richly coloured racemes during August and September. In 

 the open ground its stems rarely survive the winter, and are generally cut 

 back to the old woody stool, a new crop springing up in early summer. 



I. KIRILOWI, Maximowicz. 



A shrub or sub-shrub, with erect stems, which are slightly hairy when very 

 young, soon smooth and somewhat angular. Leaves pinnate, 4 to 6 ins. long, 

 composed of usually seven to eleven leaflets which vary in shape from 

 roundish to broadly oval, obovate, or rhomboidal, \ to \\ ins. long, wedge- 

 shaped or rounded at the base, tapered at the apex, and terminated by a
