Leaves almost sessile, clustered at the nodes, oblong, silvery-white. 
Bracteoles or calyx-wings much shorter than the fruiting-calyx .... 1. M. Montana.

1. IVI. montana (mountain plant), F. r. M. Fragm. iii. 91 ; Bentli. FI. 
Au&tr. ii. 504. A small tree, with rigid divaricate branclilets, occasionally 
spinescent. Leaves clustered at the nodes, narrow-oblong, obtuse, narrowed into 
a very short petiole, silvery-tomentose on both sides. Flowers only seen loose 
and not perfect. Calyx after flowering attaining nearly lin. but not yet ripe, 
densely silky-pubescent outside, with, short lobes. Petals apparently oblong or 
obovate, about Jin. long. Stamens longer. Bracteoles about two-thirds as long 
as the calyx, nearly orbicular, the broad almost scarious free margins folded back.

2. IVI. Leichhardtii (after L. Leichhardt), F . v , M. Fragm. iii. 91 ; Bentli. 
FI. Austr. ii. 505. Apparently more branched and not so rigid as the other two 
species. Leaves less crowded, all opposite, obovate, very obtuse, mostly J to fin. 
long, narrowed into a petiole of 1 to 2 lines, softly silky-tomentose on both sides, 
but not so white as in the other species, and becoming nearly glabrous above 
with age. Peduncles shorter than the leaves, bearing at the end 2 pedicellate 
flowers, of which I have only seen the calyx, enlarged after flowering to from 4 
to 6 lines, with the adnate bracteoles nearly as long. 
Hab.: Ruined Castle Creek, Leichhardtii. 
3. IVI. Fitzalani (after E. Fitzalan), F . v. M. Fragm. viii. 160. A tree of 
moderate size ; the tips of the branchlets silky. Leaves opposite chartaceous, 
i to ljin. long, obcordate or obovate-orbicular on petioles from 1J to 3 lines long, 
upper side glabrous, the under side sparsely pilose. Peduncles 2 or solitary, J to 
lin. long, puberulous bearing 1 or 2 flowers. Bracts opposite at top of peduncle, 
cordate-orbicular, about 1 line long, deciduous. Pedicels very slender, almost 
glabrous about the length of the calyx. Calyx 4 to 6 lines long, tube almost 
infundibaliform, teeth 5 to 7, throat bearded. Bracteoles or calyx-wings 
orbicular, almost glabrous, as long as the calyx. Petals almost sessile, ovate- 
orbicular pubescent on both sides. Stamens 10 to 13; filaments glabrous, 
setaceous, the longest about 3 lines, inflexed. Anthers dorsifixed, rotund, 
introrse, the cells longitudinally 2-valved. Style glabrous, 3 lines long setaceous. 
Stigma very minute. — F. v. M. l.c. 
Hab.: Port Denison, Gladstone, and Bowen. 
Wood near the bark yellow, the centre dark-grey ; close-grained and hard ; useful in turnery 
and cabinet work. — Bailty’s Cat. Ql. Woods No. 164a. 
4. GYROCARPUS, Jacq. 
(From the wings of fruit causing it to twirl in falling from the tree.) 
Calyx-tube adnate to the ovary, or none in male flowers ; limb 4 to 7-cleft. 
Petals none. Stamens 4 to 6, alternating with as many club-shaped staminodia, 
or fewer or none in the female flowers. Ovary inferior, with 1 pendulous ovule 
and a sessile stigma, abortive in the male flowers. Drupe dry, crowned by 2 
much elongated, erect, spathulate, wing-like calyx-lobes. Seed oblong, 
pendulous, without albumen ; cotyledons petiolate, convulate round tbe radicle. — 
Tall tree. Leaves alternate, broad, entire or lobed. Flowers polygamous, very 
small, crowded in dense corymbose cymes. 
The genus consists of a single species common to the tropical regions of Central America and 
tropical Asia. It forms one of the small group of Gyrocarpece , Dumort., or Illigerece, Blume, 
associated by many botanists with Laurinece, chiefly on account of the dehiscence of the anthers,
