of E. erythrococca beautifully blue, a note of the rarest occurrence in any tribe of the vegetable 
empire. 
Sect. I. Zieria. 
Sepaline stamens fertile, opposite to the turgid lobes of the deeply divided disk ; petaline stamens 
wanting.

Shrubby; branchlets angular; leaves sliort-petiolate, trifoliolate or a few simple; leaflets lanceolate or 
lanceolate-linear or narrow-linear, acute, revolute at the margin, paler beneath, coriaceous, glabrous or 
generally very short velvety below; flowers axillary and terminal, ternate or cymose, rarely solitary; pedicels 
as long as or shorter rarely longer than the flowers; bracteoles lanceolate or lanceolate-subulate, persistent; 
sepals ovate- or lanceolate-deltoid, generally about three times shorter than the whitish thin-velvety obovate 
short-unguiculate petals and about as long as the stamens, outside glabrous rarely downy; petaline stamens 
none; sepaline ones smooth; anthers minutely apiculate; style extremely short, as well as the ovaiy glabrous ; 
stigma minute, depressed, four-lobed; disk deeply four-cleft; carpels rhomboid-ovate; valves of the endocaip 
protracted at the junction into a deltoid tooth; seeds opaque. 
On baiTen ridges near the Goulburn River. Known besides from the southern parts of New South 
Wales. 
A shrub of variable height, in habit quite similar to the generality of Boroniae. Branchlets opposite, 
quite glabrous or much less commonly grey-downy. Petioles stout, J-3 rarely 6 lines long, somewhat 
channelled. Leaflets \-1 \ inch long, 1-3 lines broad, without special petioles. Simple leaves, if present, 
corresponding in form to single leaflets. Peduncles in various degrees shorter than the leaves, occasionally 
also longer. Bracts at the division of the peduncles opposite, either of the shape of the bracteoles or more 
alike in form to the leaves. Bracteoles placed near the middle of the pedicels, f-1 \ line long, subcoriaceous, 
semilanceolate-cymbiform, rarely lobed, or even showing in exceptional cases the metamorphosis into leaves. 
Calyx deeply cleft, seldom longer than 1 line, often tinged with black. Petals deciduous, indistinctly imbricate 
in praffiorescence, 2-2J lines long, in a small-flowered variety only about 1 \ line long, terminated by a minute 
point. Filaments filiform, affixed to the back of a half-round lobe of the disk. Anthers generally less than 
\ line long, occasionally much smaller. Pollen orange. Style with few exceptions of extreme shortness. 
Stig'ma tetragonous-capitate, four-furrowed, about ^ line broad. Carpels 1|-2J lines long, smooth, oblique 
broad-ovate, veiy blunt, with a minute apiculum. Epicarp with inside prominent net-veins. Endocarp 
shining, pale-yellowish, nerveless; its valves coherent at the concave base. Placental membrane half as long 
as the seed, semilanceolate-cymbiform, whitish. Seeds scarcely longer than 1 line, slightly tubercled. 
Chalaza thin. Embryo thin-filiform, nearly as long as the albumen. Cotyledons semiterete, half as long as 
the radicle. 
Z. microphylla (Bonpl. Nav. 64), Z. pauciflora (Sm. in Rees’ Cycl. 3) and Z. revolute (A. Cunn. in Field’s 
New South Wales, i. 330) are, as far as can be judged from the brief respective diagnosis, referable to Z. 
laevigata.
