3. T. lactiflua (sap milky), F. v. M. Fraym. i. 82 ; Benth. FI. Austr. in. 
263. A tree attaining 30ft., glabrous or the young shoots, under side of the 
leaves, and inflorescence glaucous-pubescent. Leaves alternate, often almost 
verticillate at the ends of the branches, ovate or broadly ovate-lanoeolate, obtuse 
or acute, penniveined, 3 to 6in. long, on a petiole often of lin. Flowers white, 
small and very numerous, in axillary cymes, the common peduncle often 1 to 2in. 
long. Calyx-tube broad, scarcely 1 line long, with very short rounded lobes as in 
T. sudveolens. Petals about li line diameter. Staminal bundles about as long as 
the petals, inflexed, the claws short and broad, each with 15 to 20 filaments. 
Ovary wholly adnate, concave at the top witnout any central depression. Ovules 
reflexed, not so numerous as in T. suaveolens. Fruit not seen. 
Hab.: Gulf country, E. Palmer. 
4. T. exiliflora (flowers small), F. r. M. Fraym. v. 11 ; Benth. FI. Austr. 
iii. 264. Glabrous or the inflorescence minutely hoary-pubescent. Leaves 
alternate, lanceolate or elliptical, almost acute, much narrowed into the petiole, 
penniveined, 2 to 4in. long. Flowers yellow, small, rather numerous, in small 
axillary shortly pedunculate cymes, the pedicels at length longer than the calyx. 
Calyx-tube turbinate or almost hemispherical, rather above ^ line long, lobes 
ovate, rather shorter. Petals about f line diameter. Staminal bundles inflexed, 
not exceeding the petals, the claws short, each with 2 to 4 filaments, often hairy 
at the base. Ovary half-adnate, the summit very convex, pubescent, not depressed 
round the style, with 3 to 6 pendulous ovules in each cell. Fruit obovoid- 
globular, about 2 lines diameter, adnate at the base only, filling the calyx-tube 
and protruding considerably beyond it. Seeds obovoid, not much flattened, the 
testa sometimes with a short appendage or quite wingless, often lined with a 
granular substance. Cotyledons broad, deeply lobed and closely folded over the 
radicle. 
Hab.: Rockingham Bay, Dallachy , and many other tropical localities. 
The species is very closely allied to T. laurina, with the same foliage, floral characters, and 
fruit, but with the flowers as small as in T. lactiflua , and the seeds, as far as known, not winged.

5. T. laurina (Laurel-like), li. Br. in Ait. Hort. Kew ed. 2 iv. 417 ; Benth. 
FI. Austr. iii. 264. Water Gum. A somewhat scrubby shrub in exposed locali- 
ties, becoming in moist situations a tree, often of great height, the young shoots 
more or less glaucous or silky-pubescent, especially the under side of the leaves, 
the older foliage glabrous. Leaves alternate, lanceolate, elliptical or obovate- 
lanceolate, acuminate, penniveined, 2 to 4in. long, narrowed into a petiole. 
Flowers yellow, in short axillary cymes, on a very short common peduncle, the 
pedicels rarely longer than the calyx. Calyx-tube broadly campauulate, 1^ to 21 
lines diameter, lobes small, triangular, distant at the time of flowering although 
imbricate in the young bud. Petals 1J to 2 lines long, usually undulate. 
Staminal bundles inflexed, scarcely exceeding the petals, the claws very short, 
each with 15 to 20 filaments. Ovary half-adnate, the summit very convex, 
hirsute, not depressed round the style, with several (about 10) reflexed ovules in 
each cell. Capsule obovoid or almost globular, 3 to 5 lines diameter, adnate at 
the base only, filling the calyx-tube and protruding considerably beyond it. Seeds 
oblong, flat, laterally attached near the top, the upper part thin and wing-like, 
embryo in the lower thickened portion ; cotyledons deeply cordate and folded over 
each other; radicle superior, rather long. — DC. Prod. iii. 210; F. v. M. Fragm.

Hab.: Along creeks, southern localities. Flowering in December and January. 
Wood of a dark colour, close-grained, very tough and strong ; useful for tool-handles —
