6. T, longivalvis (valves of fruit long), F. v. M.; Whu/'s South. Sci. Rec., 
new series, ii., April 1886. Buttercup Tree. A tree of small size, the branchlets 
pendulous. Leaves scattered on very short petioles, obovate, attaining a length 
of 4in. with a breadth of 2in., glabrous, finely penninerved and thinly net-veined, 
somewhat shining above and paler beneath. Cymes axillary or lateral, very 
spreading, the peduncles slender ; pedicels as long as or longer than the flowers, 
thickened upwards. Calyx-lobes semi-orbicular, deltoid, shorter than the tube. 
Petals orbicular, yellow, glabrous, about 4 lines wide, hardly contracted towards 
the base. Stamens shorter than the petals, numerous in each fascicle, the anthers 
terminated by a turgid gland. Ovary half-adnate to calyx-tube ; ovules numerous 
in each cell. Style 3 lines long, subulate, glabrous; stigma scarcely dilated. 
Fruit nearly 6 lines long ; valves 3, deltoid-lanceolate, acute, and hard ; seeds 
rather numerous in each cell and closely packed, broad, much compressed, and 
terminating in a conspicuous membrane, nearly 3 lines long. — F. v. M. l.c. 
Hab.: Prince of Wales Island, R. Brown ; Thursday Island, Rev. B. Scortecliini ; Cape York, 
B. Gulliver. Flowering about June. 
Wood of a straw colour, close-grained, very hard and tough, stands well in drying, and will 
likely prove valuable for building purposes. — Bailey's Cat. Ql. Woods No. 20(ic (there given as 
probably T. macrosperma, F. v. M., a New Guinea species). 
17. SYNCARPIA, Ten. 
(Referring to the carpels being united.) 
(Kamptzia, Nees.) 
Calyx-tube turbinate or campanulate, adnate to the ovary at the base, the free 
part erect or dilated ; lobes 4 or rarely 5, persistent. Petals 4 or rarely 5, 
spreading. Stamens indefinite, free, in 1 or 2 series, sometimes interrupted 
between the petals, filaments filiform ; anthers versatile, cells parallel, opening 
longitudinally. Ovary inferior, flat-topped or convex, scarcely depressed round 
the style, 2 or 3-celled, with 1 or several ovules in each cell, erect on a basal 
placenta ; style filiform with a small stigma. Capsule included in and adnate to 
the calyx-tube, opening loculicidally in 2 or 3 valves. Seeds linear-cuneate, testa 
thin, embryo straight, cotyledons plano-convex, longer than the radicle. — Trees. 
Leaves opposite, penniveined. Flowers in dense globular heads, either solitary 
on axillary peduncles or forming terminal panicles. 
The genus consists of 3 species exclusively Australian, and differing perhaps as much from 
each other as either one does from Metrosideros. — Benth. 
Calyxes hoary, connate. Petals broad. Ovary 3-celled, with several ovules 
in each cell. Flowers in each head 6 to 10 1. S. laurifolia. 
Calyxes connate, glabrous ; the foliage and flowers much larger than in No. I. 
Flowers in each head usually 7 2. S. Hillii. 
Calyxes free. Petals narrow. Ovary 2-celled, with 1 ovule in each cell . . 3. S. leptopetala. 
1. S. laurifolia (Laurel-leaved), Ten. in Mem. Soc. Ital. Sc. Moden. xxii. t. 1 ; 
Tenth. FI. Austr. iii. 265. Turpentine tree. A slender tree, the young shoots 
and under side of the leaves more or less hoary-pubescent or glaucous. Leaves 
appearing sometimes in whorls of 4 from 2 pairs being close together, from 
broadly ovate to elliptical-oblong, obtuse or obtusely acuminate, glabrous above, 
2 to 3in. long, on petioles of \ to ^in. Flowers white, united, 6 to 10 together 
in globular beads, on peduncles of f to lin. at the base of the new shoots, with 
2 to 4 bracts close under the head, either short and scale-like or leaf-like and 
exceeding the flowers. Calyxes connate at the base, the free parts broadly cam- 
panulate, softly hoary-pubescent, 1 to l\ line long, lobes short, broad and obtuse. 
Petals broadly ovate or orbicular, about line long. Stamens 3 to 4 lines 
long, in about 2 rows round a flat disk fully 3 lines diameter. Ovary flat-topped, 
tomentose, 3-celled, with rather numerous ovules in each cell, erect on an oblong 
placenta. Fruiting-heads about -Jin. diameter, the calyxes connate to about the
