TEREBINTHACE.33. 231 



Trees or shrubs, natives of America ; leaves compound ; 

 leaflets pellueido-punctate ; flowers panicled, white. Drupe 

 turgid with an aromatic oil. Name, from ftvega myrrh, from 

 the valuable gum or resin, which almost every species of this 

 genus affords. 



1. Amyris sylvatica. Shrubby Torch-wood. 



Leaflets 1 -paired with an odd one subrotundo- 

 ovate acuminate crenulated petiolulated, the odd 

 leaflet the largest. 



Baccifera trifolia racemosa, flosculis albis tetrapetalis, fructu 

 nigro monopyreno fcetido, Sloane, II. 101. Amyris fruticosus 

 minor, foliis orbiculatis pinnato-ternatis, Browne, 209. A. 

 sylvatica, Jacq. Amer. 107. A. maritima, Sicartz, Obs. 148. 



HAB. Common in Port-Royal mountains. Thickets near 

 the Sea-shore. 



FL. May August. 



A shrub, varying from 215 feet in height; branches few, 

 long, terete, verrucose, ash-coloured. Leaves at the extremi- 

 ties of the branches, ternate : leaflets ovate or rhomboideal, 

 rounded or occasionally subattenuated at the base, acuminate at 

 the apex which is blunt, slightly crenated, or, where the soil is 

 rich, duplicato-crenated, glabrous, pellueido-punctate, mem- 

 branaceous, 2 inches or more in length : common petiole com- 

 pressed : petiolules short, terete. Panicle terminal and axil- 

 lary, and alternately branched ; flowers numerous, small, white. 

 Calyx persistent, minute, 4-fid, with the divisions blunt. Drupe 

 globose, black, size of that of a Pimento berry : nut oval. 



This is a common shrub in thickets, and varies in the size 

 and form of the leaves, flowers, &c., from soil and situation. I 

 have no doubt, but that the following species of Jacquin, is pro- 

 perly a variety of the one we are at present considering. 



2. * Amyris maritima. Sea-side Amyris. 



Leaflets 1 -paired sessile with an odd one petiolu- 

 lated, ovate crenated obtuse.

 Candolle.
