 taste of liquorice. Native of Dauria. See t le sixth species.

 ple, subsolitary; leaves abruptly pinnate, two-paired ; petioles 

 and stipules spinescent ; branches decumbent. A hardy 

 shrub, flowering in May and June. Flowers large, pendu- 

 lous, yellow; the disk of their standard first green, afterwards 

 deep red. Native of China. See the sixth species. 



10. Robinia Squamata. Racemes with pedicels, one- 

 flowered ; leaves unequally pinnate ; leaflets oval, spiny, 

 muoronate ; petioles unarmed. Native of the island of St. 

 Thomas in America. See the second species. 



11. Robinia Florida. Peduncles simple, one-flowered; 

 leaves abruptly pinnate ; petioles and stipules unarmed. 

 This very handsome shrub is leafless in the time of flowering, 

 when it is quite covered with flowers. Native of Krabben 

 island in America. See the second species. 



12. Robinia Halodendron ; Salt- Tree Robinia. Peduncles 

 three- flo wered ; leaves abruptly pinnate, two-paired; petioles 

 and stipules spinescent; legumes inflated. This is a small 

 irregular tree or shrub, commonly of the height of a man ; it 

 is very much branched, and rigid, but silky all over. Native 

 of Siberia, in dry salt-fields, growing by the river Irtis, and 

 flowering in June. It flourishes in gardens, but has never 

 produced flowers in them, probably for want of the saline 

 principle in the soil. See the sixth species. 



13. Robinia Frutescens; Shrubby Robinia. Peduncles 

 simple ; leaves in fours, subpetioled, terminated by an un- 

 armed spine. It grows with a shrubby stalk eight or ten 

 feet high, sending out several branches which grow erect, 

 covered with a smooth yellowish bark. Flowers yellow. 

 Native of Siberia, See the sixth species. 



14. Robinia Pygmsea; Dwarf Robiria. Peduncles quite 

 simple; leaves in fours, sessile. Trunk covered with a 

 shining yellowish bark; wood of a very deep bay, almost 

 as hard as horn. Native of Siberia, where this elegant 

 species begins by the Irtis, in the southern rocky open parts; 

 becomes more frequent by the Jenisca ; and most common 

 in the regions beyond the lake Baikal. It rises commonly 

 with twigs an ell in height; these twigs are very tough, and 

 fit for withes; and the flowers are of an elegant golden 

 colour. See the sixth species. 



15. Robinia Subdecandria. Racemes simple; filamenta 

 almost distinct; leaves unequally pinnate; stem unarmed. 

 Root branched, having the smell and taste of Liquorice.
