being projected from the lower edge ; keel rather longer than the alie, 

 rose-coloured in its edges, everywhere else pale lilac, its jietals united 

 except at the claws, which are callous, at first straight, and afterwards 

 bent down elastically, separating very widely the keel and alae from the 

 vexillum, somewhat hairy towards its edge and hack, toothed on the up- 

 per edge ot its claws, and having a distinct papilla on each side. Sta- 

 mens diadelphous, included within the keel; filaments purple, glabrous, a 

 very short ascending portion only being free ; anthers green, muo'onate, 

 pollen-granules extremely minute. Pistil little longer than the stamens ; 

 stigma minute; style pubescent; germen linear, glabrous; ovules about 10. 

 This very handsome shrub has stood for several years in the open air in the 

 Botanic Garden, Eilinburgh, and flowered for the first time in July 1834. 

 We received it from Mr Thomas Hogg, Clapton, in 18-20, marked with a 

 query as a species of Indigofera. It differs from Roxburgh's description of 

 /. violacea in having the raceme rather longer than the leaf. I should have 

 considered it his /. arborea, had it not been that the branches are erect, 

 not " spreading in every direction," and had it not been reasonable to 

 expect that /. arborea would have attained a larger size in a shorter 

 time. There is a very near affinity between /. cassioides, Rottl., /. vio- 

 lacea, Roxb., I. arborea, Roxb., /. Jirahulia, Hamilton, and the specimens 

 which I named /. verrucosa in Wallich's List of Plants in the East India 

 Company's Museum. If they shall prove to be specifically the same, 

 the name of /. cassioides should be adopted, as published by DeCandolle 

 in his Prodromus in 1825. I have no specimen of /. violacea from the 

 Botanic Garden, Calcutta, with which to compare our plant, and the 

 specimens of /. arborea from thence have the branches much diffused.

 Herb. No. 735. 

 Description. — Stem elongated, slightly branched, hoarj'-pubescent, some- 

 what flexuose, nearly round. Leaves (3 inches long) divaricated, leafets 

 (9 lines long, 2i broad) in 10-12 pairs, oblongo-linear, hoary.pubescent on 

 both sides, concave above, nearly pointless. Stipules acuminato-subulate, 

 adhering for a little way round the stem at the base. Racemes axillary, on 

 peduncles, gradually elongating, and when in fruit as long as the leaves. 

 Flowers scattered loosely upon a rachis as long as the peduncles, spread- 

 ing upon very short pedicels. Calyx, like the peduncle, pedicel, and 

 every part of the plant, except the corolla, stamens, and style, hoarv, the 

 lower teeth the longest. Corolla pale rose-coloured ; vexillum, wliich is 

 the darkest petal, and slightly striated, elliptical, erect, reflexed in the 

 sides, and keeled, slightly notched ; alse rather shorter than the vexil- 

 lum, hatchet-shaped toothed at the base, claw linear, thrice as long as 

 the tooth ; keel half as long as the alse, blunt, flattened on its lower side, 

 tijjped with greenish-yellow, its petals free only for a little way above 

 the insertion of its linear claws, its teeth short and blunt. Stamens dia- 

 delphous, filaments glabrous, anthers orange-coloured, polleu-granules 

 small, round, glistening. Germen covered with white silky hairs. Legume 

 (unripe) turgid, ovate, somewhat compressed, pubescent, about 5-seeded. 

 This plant, found by Mr Cuming at Valparaiso, we received in the Bota- 

 nic Garden, Edinburgh, from that of Birmingham in spring 1834. It 

 flowered in the greenhouse in June and July.
