 The specimens are very unsatisfactory ; several with the narrowest leaves arc in leaf only, 

 others with rather broader leaves are in flower. None have the fruit attached ; the loose 

 fruits are deposited in F. Mueller's hciharium as belonging to one of the narrow-leaved spe- 

 cimens. The evidence, therefore, which has induced me to refer the flowering specimens 

 with numerous stamens to the oblong rather than to the globular fruits, is far from conclu- 

 sive, and the qucsuon cannot be detei-mined until undoubted flowers of the globular-fruited 

 tree shall have been more fuUv examined. 



OitDER XXIX. SIMAEUBEJE. 



Flowers regular, dicecious or polygamous, more rarely heriuaphrodite. 

 Calyx usually small, 3- to 5-lobed, or divided into as many distinct sepals. 

 Petals 3 to 5, hypogj^nous or slightly perigynous, imbricate or valvate in the 

 bud, rarely wanting. Stamens either equal in number to the petals, and 

 alternating with them, or double the number, anthers usually versatile, with 



2 parallel cells opening longitudinally. Disk annular, cupular or elongated 

 within the stamens, under or round the ovary, or rarely none. Gynoecium pi 



3 to 5, rarely more or fewer carpels, quite distinct, or more or less united mto 

 a single lobcd or rarely entire ovary, with one cell to each carpel. Styles as 

 many as carpels, united from the base or by the stigmas only, or entirely dis- 

 tinct. Ovules solitai-y in each cell, or very rarely 2, tlie uiicropyle superior. 

 Pruit-cai-pels either di.stipct, dry .or. drupaceous, usually indchiscent, or united 

 in a single drupe or capsule. Seeds usually solitary in each carpel or cell, 

 pendulous; testa membranous; albumen abundant, or little, or none. Em- 

 bryo straight or curved; cotyledons flat or convex, rarely twisted; radicle 

 superior. — Shrubs or trees, with a bitter baric. Indumentum of simple not 

 stellate hairs. Leaves alternate or rarely opposite, pinnate or simple, usually 

 without glandular dots. Stipules none, except in CadelUa. Flowers usually 

 small, in axillary or rarely terminal panicles or racemes. 



The Order consists of a considerable number of small genera, chiefly tropical, dispersed 

 over the New as well as the Old Worid. Of the 6 Australian genera, 3 belong to tropical 

 Asia, one of which extends also into Africa, 2 are endemic, and the sixth is on the seacoasts 

 of all tropical countries. The Order as a whole is somewhat heterogeneous, and especially 

 has no peculiar habit 

 it differs chiefly in the 



has no peculiar habit. In technical characters it is closely allied to Euiacea, from which 



e biUcr bark, the waut of pellucid dots to the leaves, and in the soli- 

 tary ovules, but each of these characters has some exceptions.
