(Harrisonia, Brunellia), or 2-foliolate (Balanites), or simple (Cneorum, Castela, 

 Soulamea, &c.), not dotted, very rarely stipulate (Brunellia, Irvingia, Cadellia). 

 FLOWERS diclinous or polygamous, regular, usually axillary, panicled or racemed, or 

 rarely the $ in a spike, the ? solitary (Picrodendron}. CALYX 3-5-lobed or -partite, 

 regular, very rarely sub-bilabiate (Hannoa), aestivation imbricate or valvate. PETALS 

 3-5, very rarely (Brunellia, Amaroria), free, or very rarely connivent into a tube 

 (Quassia), hypogynous ; aestivation imbricate, valvate or contorted. DISK annular, 

 cupuliform or tumid, entire or lobed, sometimes elongated into a column (Quassia, 

 Cneorum), rarely inconspicuous (Suriana, Picrolemma), or (Spathelia, Eurycoma, 

 Cadellia). STAMENS inserted at the base of the disk, double the number of the 

 petals, or equal and alternate, very rarely opposite to the petals (Picrolemma, 

 Picramnia), very rarely more than 10 (Mannia) ; filaments free, naked or more often 

 hairy, or furnished with a scale at the base ; anthers oblong, usually introrse, 2- 

 celled, dehiscence longitudinal. CARPELS 2-5, rarely solitary (Cneoridium, Amaroria), 

 completely free (Brunellia, Suriana), or connate at the base only, or cohering by the 

 styles only, or completely united into a 2-5-celled ovary ; styles 2-5, free at the base 

 and top ; stigmas free or cohering in a head ; ovules usually solitary in each cell, 

 sometimes geminate, very rarely 4-5 (Dictyoloma), or oo (Kceberlinia), fixed to the 

 inner angle of the cell, anatropous, raphe ventral and micropyle superior, very rarely 

 ascending with a dorsal raphe and inferior micropyle (Cneoridium). FRUIT usually 

 of fleshy or dry drupes, rarely of 2-valved capsules (Dictyoloma, Brunellia), or inde- 

 hiscent (Soulamea), very rarely of samaras (Ailantus). SEEDS pendulous, usually 

 solitary; testa membranous ; albumen usually or scanty, rarely copious (Cneorum, 

 Brucea, Brunellia, Spathelia). EMBRYO straight or rarely curved (Cneorum, Suriana,

The family of Simarubeee, as reconstituted by Bentham and Hooker fil. and Planchon, only dilfers 

 from Rutacea, Diosmete, Zanthoxylea, and Hesperideee in its eglandular leaves, often bitter bark, and 

 filaments usually furnished with a scale ; characters which, although not of a high intrinsic value,
