crustaceous or scarious. Seeds 1 rarely 2 in each cell. Testa bony or crustaceous. Albumen copious. 
Cotyledons compressed. 
Shrubs and trees, noticed throughout Eastern Australia, in the warmer parts of Asia, in Norfolk 
Island and in New Caledonia. Leaves opposite , rarely alternate, consisting of a single leaflet, rarely 
trifoliolate. Cymes axillary and terminal. Petals white or yellowish-green.— Schott Rutac. 3, t. 2 & 3 ;

This genus stands on the verge of Aurantiaceae; in the structure of its seeds it agrees fully with 
Xanthoxylese.

Leaves opposite or some few alternate, consisting of a single rarely of three ekartaceous or at length 
coriaceous ovate-oblong or obovate pellucidly dotted leaflets; cymes nearly glabrous; lobes of calyx almost 
round, very small; petals deciduous, narrow-oblong, blunt, inflexed at and towards the apex; filaments 
tomentose at the lower margins and inward above the base; anthers didymous-ovate; style downy below 
the middle; stigma veiy minute, undivided; ovary smooth; disk glabrous , repand; fruit four-seeded; 
endocarp scarious , separating from the thin pericarp ; cells much wider than the seeds; seeds small; testa 
crustaceous; embryo nearly of the length of the albumen. 
Rare in forest-ravines at Lake King and Lake Tyers, in about 38° S. latitude; this being the most 
southern locality attained by any aurantiaceous plant; not rare in humid forest-valleys of Eastern Australia; 
known northward as far as Keppel Bay. 
A noble tree, reaching the height of 60 feet. Bark almost smooth, sordidly grey. Alburnum brown- 
red. Wood pale, rather soft. Branchlets terete, as well as the petioles smooth or very slightly downy. 
Petioles J-l inch long, channelled-cylindrical or semiterete, jointed at the summit. Leaflets 1J-6 inches 
long, f-2 inches broad, in exceptional instances fully 9 inches long and 3J inches broad, glabrous, rather 
acute at the base, blunt and often slightly emarginate at the apex, spreacling-nerved, net-veined, not much 
paler beneath, more or less shining particularly above, generally with a glassy lustre in age, copiously dotted 
with very transparent aromatic somewhat lemon-scented oil-glands. Cymes chiefly axillary, occasionally 
terminal, few- or many-flowered, simple or repeatedly branched. Primary peduncles often shorter than 1 
inch, almost terete; secondary one generally more slender, a few lines sometimes many lines long, occa¬ 
sionally reduced to extreme shortness. Pedicels filiform, from 1 to a few lines in length. Bracts and 
bracteoles at the base of the peduncles and pedicels, very minute, semilanceolate or nearly so, slightly downy, 
early dropping. Flower-buds lagenar-ovate. Lobes of the calyx § line long, glabrous, persistent. Petals 
white, deciduous, about J inch long, valvate in aestivation, on account of their marginal inflexion narrower 
towards the apex than towards the base, sessile. Stamens 8 ; those opposite to the sepals somewhat longer 
than those in front of the petals. Filaments inserted outside the disk, linear-subulate, coherent at their 
velvety margin. Anthers yellow, dorsifixed, about J line long*, with introrse longitudinal dehiscence. Disk 
narrow, annular. Style 1-1 \ line long, subulate, deciduous, silky-tomentose or laxly pubescent beneath the 
middle. Stigma not broader than the style, blunt, slightly four-furrowed. Ovules 2 in each cell, affixed 
near the middle of its internal angle, descendent. Young fruit yellowish-brown, globose-ovate, with four 
rather acute longitudinal ridges; ripe one about \ inch long*, of aromatic scent, tetragonous-globose, tinged 
with red. Dissepiments thin. Endocarp scarious, brittle, nerveless, separable into two valves. Seeds 1 or 2 
in each cell, both descendent, the one placed obliquely above the other, immediately attached to the angle of 
the cell, oblique reniform-ovate, sordid grey-brown or black, 1-1 \ line long. Raphe separable. Chalaza 
inferior, large, protruding, shining-black. Testa smooth or but slightly tubercled. Albumen rather copious. 
Cotyledons elliptical, compressed, twice as long as the cylindrical superior radicle.
