1 line. Calyx-tube narrow-turbinate, attaining 1J line ; lobes orbicular, scarious, 
about half as long as the petals. Stamens 5, opposite the petals. Ovary 1-celled 
with a cluster of 6 to 8 ovules suspended from the top of the cavity on a filiform 
placenta arising from the base as in .V. tnicrophylla. — Backed leptocalyx, F. v. M.

Calyx-tube turbinate or hemispherical, adnate to the ovary at the base, the free 
part broad and open ; lobes 5, imbricate, continuous with the tube or more or 
less scarious, usually persistent. Petals 5, broadly obovate or orbicular, longer 
than the calyx-lobes, spreading. Stamens rarely exceeding 20 and often under 10, 
free, in a single row round the margin of the disk, and usually horizontally 
inflected in the bud. Filaments filiform or flat ; anther-cells united or distinct, 
opening in longitudinal slits or in small pores. Ovary adnate to the lower part 
of the calyx-tube or enclosed in it, and rather more or less convex at the top or 
semiadnate or free except the broad base, 2 or 3-celled, with 2 collateral or several 
ovules in each cell, in 2 rows or in a ring round a more or less peltate placenta ; 
style filiform, glabrous, inserted in a deep tubular or rarely shallow depression in 
the centre of the ovary ; stigma capitate or peltate. Capsule partially or wholly 
superior, enclosed in the scarcely enlarged calyx-tube, opening at the top locu- 
licidally in 2 or 3 valves. Seeds either 1 or 2 in each cell and reniform, or 
several and more or less angular; testa thin or slightly crustaceous; embryo 
filling the seed, the radicular portion thick and clavate, with a slender short neck 
folded against the side and shortly divided into 2 ovate or oblong cotyledons. — 
Heath-like "glabrous shrubs. Leaves small, opposite, entire. Flowers small, 
white or pink, either solitary in the axils on a peduncle articulate at, above, or 
rarely below the middle, with 2 small bracteoles at the articulation, or several 
together on a short common peduncle with a small bract at the base of each 
pedicel. 
The genus is chiefly Australian, but one of the common East Australian species extends into 
New Caledonia, and 2 or 3 others not Australian are found in New Caledonia or in the Indian 
Archipelago and S. China. — Benth. 
Much as several of the species differ from each other in the stamens as well as in the ovary, 
it is exceedingly difficult to distribute the whole into good sections, for the different forms 
appear either to pass into each other by almost insensible gradations, or to be strictly monotypic, 
and none have appeared to me to be sufficiently accompanied by differences in habit or by any 
combination of characters to justify the adoption of any of the long list of separate genera 
proposed by Schauer and others. The presence or absence of the five stamens opposed to the 
petals is perhaps the most marked, but even that appears to be uncertain in the few cases where 
the stamens exceed 20. — Benth. 
Stamens few or numerous, hut none opposite the centre of the petals, excepting very rarely, when 
there are more than 20. Ovules several in each cell.
