This is a very' remarkable plant, differing in several points from Phebalium ; hut not being iu fruit, I am unwilling
to establish a neiv genus o f it.— A small bush. Stems, and especially branches, covered with reddish bark,
minutely puberulous towards the tips with simple o t stellate hairs. Leaves scattered, 4 - 3- inch long, coriaceous,
oblong, but rounded at the base and truncate or emarginate at the apex, coarsely toothed, coriaceous, paler and
dotted beneath. Flowers small, whitish, in small terminal erect cymes, hidden amongst the leaves. ' Peduncles and
pedicels with silky pubescence.. Calyx minute, four-toothed. Petals lanceolate, concave, valvate, with incurved
tips, one-nerved. Stamens four, alternate ones shorter ; filaments glabrous, filiform, rather thickened about the
middle, apex subulate. Anthers shortly-oblong, with an ari^hed protuberance over the apex o f the filaments.
Pollen globose. Ovary deeply two-lobed ; lobes ereet, with a few bans at the tips, two-ceUed ; cells with two collateral
ovules adnate a little above the middle by broad bases. Style straight, erect, subidate. Stiyma simple,
minute. Carpels immature, one only ripening, oblong, with a rather narrowed recurved tip.— P l a t e IX. Fig. 1,

This, so far as its diagnostic characters are concerned, appears to be quite an artificial genus, the three points
by which it is distinguished from Phebalium being trifling, and none o f them absolute. These are— the stamens
being generally shorter than the petals, the filaments being pilose, bearded, or villous, and the anthers having the
connective produced beyond the cells into a small point. Wben taken together, however, these group a large
number of plants, aU, different-looking from Phebalium, and they may therefore serve to establish the genus. About
thirty species are known, all but one natives of extratropical Australia, chiefly of the West Coast. (Name from

A small, heathy shrub, 2 feet high, covered with granular tubercles, each fidl of essential od, and with a depression
at the summit.— Stems and branches greeu. Leaves 4 - 4 inch long, very thick and somewhat fleshy, obcordate,
glandular on both surfaces. Flowers numerous, solitary, axillary, 4 inch across, pink, rarely white. Fedieels
much shorter than the leaves. Calyx-lobes very small, rounded. Pe tals five, obovate-oblong. Stamens alternately
shorter; filaments dilated, flat, ciliated or pilose, subulate at the tips. Anthers ovate, subcordate, with short apiculi.

A slender species.— Branches tuberculated with prominent glands. Leaves obcuneate-lanceolate or linear-
obovate, blmit or apiculate, 4 - 4 inch long, coriaceous, smooth above, whitish below, there dotted ivith prominent
glands. Flowers tetramerous, 4 - 4 inch across, pink. Stamens with curved filaments, thickened and woolly above
the middle, thence contracted into subulate glabrous apices. Anthers versatile, hardly pointed. Carpels (unripe)
rather narrow, with recurved tips.— I have (Joum. Bot.) erroneously called this plant a native of Australia.

An Australian genus, o f which rather more than a dozen speeies are known, chiefly natives of the east coast,
one or two entering the Tropics. The only Tasmanian species is also a New South Wales one, and extremely
variable in foliage.— Shrubs with opposite, simple, or trifoliolate leaves. Calyx smaU, four-lobed. Petals four.
Stamens fom- ; filaments glabrous, inserted iu a deeply lobed disc ; anthers cordate, versatile. Ovaries four ; ovules
two in each. Style short, simple, with a capitate stigma. Capsule of four cocci. (Named in honom- of M. Zier,

There are certainly thi-ee nearly allied species of Zieria, all fouud in Eastern Australia-, one has small flowers,
and is found to the north o f Sydney at Brisbane River and Sti-adbrooke Island, it is the Z. macrophylla o f D elessert’s
leones ; the second, from Sydney itself, has tuberculated branches, and is the Z. Smithii, Sims, Bot. Mag. t. 1395 ;
and the third, from South-eastern Australia, which I assume is the same as the Tasmanian plant, has smooth branches,
and is figm-ed hy Andrews (Bot. Rep. 1. c. sub nom. Z. Smithii). This latter differs from the description of Z. ar-
borescms in Sims, Bot. Mag. (appended to that of Z. Smithii), in the leaves being punctate below.— A shrub, 4 -9
feet long. Branches smooth, the ultimate ones pubescent. Petioles I - I 4 inch long. Leaflets 1 - 4 mches long, lanceolate,
acute or acuminate, nan-owed at both ends, glabrous above, paler and dotted below, sometimes pubescent.
Panicles almost as long as the leaves, ternately branched, pubescent, many-flowered. Flowers white, 4 inch diameter.
Carpels two or three only ripening, strongly nerved.
