A shrub about 6, or a tree 15 feet in height : branches 

 erect, of an ash colour, rough with small whitish asperities, 

 glabrous. Leaves sub-opposite, impari-pinnate : leaflets 2- 

 paired with an odd one, petiolulated, ovate, more or less 

 rounded at the base, acuminate with the apex acute, subentire, 

 very glabrous, of a bright green, somewhat shining and obscurely 

 nerved above, pale and reticulato-venose beneath, pellucido- 

 punctate : common petiole terete : petiolules short, terete. 

 Panicle terminal, sessile (i. e. no common stalk) : peduncles 

 several, arising from the end of the branch, compressed, pu- 

 berulous, subdivided : branchlets short, compressed, puberu- 

 lous, with a small ovate bractea at the base of each. Flowers 

 numerous, white, slightly fragrant, very shortly pedicelled, in 

 threes, with a pair of minute bracteoles below each flower. 

 Calyx minute, 4-fid ; divisions ovate, ciliated, glanduloso-punc- 

 tulate. Petals 4, cuneato-unguiculated, concave, patenti-reflex, 

 glanduloso-punctate. Stamens 8, of nearly the same length as 

 the petals, patent : anthers white. Ovary seated on an amber- 

 coloured disk, ovoid, minutely puberulous : stigma subsessile, 

 capitate. 



The branches of this shrubby tree, when broken or bruised, 

 exhale a strong smell. Swartz mentions that he had not an 

 opportunity of examining it. 



There are two additional species, A. PHILIPP^EA, and A. 

 ROBINSONII, noticed by Mr. Anthony Robinson, in Long's His- 

 tory of the Island. In both, the leaves are 3-foliate, and the 

 petioles margined. 



IX. EXOTHEA. 



Calyx 3-partite. Petals 5, shortly clawed, alter- 

 nating with the divisions of the calyx. Stamens 7-8. 

 Ovary supported on an annular fleshy disk. Drupe 

 with the nut chartaceous, 1- rarely 2-seeded: radicle 

 superior. 



Name, from s%udtu to expel; the plant about to be de- 

 scribed, being allied to the AMYRJDE^E, but separated from them 

 by certain characters.
