246 OCTANDRIA MONOGYNIA. Amyris, 



ed juice, but unfortunately for my conjecture, it is soon 

 carried off by evaporation, leaving little or nothing be- 

 hind. I have at various times of the year wounded the 

 plant in different places, and placed various contrivances 

 to collect the juice, but all 1 could ever procure, was a

3. A. gileadensis. Willd. 2. 334. 



Shrubby, the branches and branchlets spinous. Leaves 

 short-petioled, ternate ; leaflets from oval to elliptic, ser- 

 rulate, smooth, 



A native of Arabia. It has not yet blossomed in the 

 Botanic garden at Calcutta, though a pretty large plant 

 has been there five years. 



4. A. acuminata. R. 



Arboreous. Leaves ternate, and quinate, rarely of se- 

 ven leaflets, pinnate ; leaflets Y)etio\e6, from ovate to oval, 

 entire, acuminate, smooth. Peduncles diverging, three- 

 flowered, or trichotonious, and many-flowered. Stamens 

 shorter than the pistillum. 



Introduced into the Botanic garden at Calcutta from 

 the Moluccas, in 1798. In 1808 the young trees had ac- 

 quired a short trunk, of eighteen inches in circumference, 

 and not very straight, covered with very smooth greenish 

 ash-coloured, fleshy bark. 



Branches stiff but brittle and spreading in every direc- 

 tions ; bark thereof like that of the trunk. In Bengal they 

 blossom in May, but have not yet produced ripe fruit. 

 Leaves alternate, ternate, and quinate-pinnate, rarely 

 seven, and nine still more so; in Bengal deciduous in 

 November and December, and appearing with the flow-
