I D i s t r i b . S outh-eastern Australia.
A vei}' variable shnib, according to Gunn ; forming a small scrubby bush near the sea and on poor sandy soil,
and a fine hushy shrub, 6 feet high, on richer soil in the interior.— Everywhere perfectly glabrons. Branches slender,
often spreading. Leaves opposite, rai-ely ternate, small, verj' variable in size, breadth, and araoimt Of concavity,
generally 3 ^ lines long, sessile, obovate, blunt, appressed to the branch, which they partly embrace, at other times
flatter, three-nerved on the back, shorter aud spreading. Flowers in small heads, teiminal or lateral, o f a fine
piirple colour.
Obs. Melaleuca fascicularis, Lab. Nov. Holl. ü. 29, 170 (Astartea fascicularis, DC. Prodr. iii. 210), stated
by LabiUardiere to have been found in Tasmama, is uot so, but a native o f South-western Australia.

A small Australian geuus, containing about fifteen species.— Shrubs with alternate, exstipulate leaves. Flowers
pedieelled, axiUary or terminal, often panicled or subcapitate. Cfeíyí-tube beU-shaped, with a five-lobed Hmb.
Stamens placed on a lin g in the mouth o f the caljx:, very numerous ; filaments free. Ovary attached by its lower
part only to the calyx, two- or three-ceUed; cells many-ovuled. Capsule enclosed within the coriaceous tube of the
calyx, with a loeuHcidal dehiscence. (Name in honour o f Gustav Kunze, a Germau cryptogamic botanist.)

A shrub 9 -1 2 feet high.— Branches glabrous, the ultimate often pubescent. Leaves imbricate or fascicled, on
short, lateral branches, Hnear or Hnear-lanceolate, sharp or blunt, nerveless, 4 - 4 inch long. Flowers numerous in
the fiTilq o f the upper leaves along the lateral branches, hence often appearing to form elongated, interrupted spikes.
FUncers shortly pedieelled. Calyx somewhat pilose, its lohes spreading, lanceolate. Fetals sraaU, white or yellowish.

The species o f this genus are confined to Australia and Tasmania ; about fifteen are known. I t is nearly
allied to Melaleuca in the adnate ovary and sessile calyx, which becomes indurated and connate with the branch,
but differs in the free filaments. The inflorescence forms spikes in the middle o f the branches, and in young
branches of some species the flowers may be detected immersed in the wood of the branch for many months before
they burst through. (Name from k oA X wto s, most beautiful, and cm)¡JAov, a stamen.)

A very variable plant according to Gunn, inhabiting many situations wet and dry, at times even gi'owing in
water six feet deep iu Lake St. Claft, as Calycothrix does. A shrub varying from 1 -6 feet high.— Leaves very close

At first sight this does not appear to differ much from C. viridiflonm, but it is quite a distinct species, having
much lai-ger and less rigid leaves, ivith shorter stamens. Planchón (Herb. Hook.) doubts if the Tasmanian plant
be the same as Smith’s and Sims’ Australian one, but I find no difference between them, except that the calyces ol'
the former are sometimes but not always hairy, and the leaves are hardly so long.

The Gum-trees form one of the largest and most important genera o f plants in Austraha, and that wliicli
contains by far tbe gi-eater nmnber o f forest-trees. They abound in all parts of the continent and in Tasmania,
ñiHy 130 speeies being known, of wliich 50 are confined to South-western Austraha, 60 to South-eastern Australia,
and 20 are tropical species. I t is most remarkable that, with the exception o f a Timor and a few Molucca Island
species, none have been foimd elsewhere but in Australia.
The species are extremely difficult of discrimination, nor can they be properly determined from dried specimens,
important eharacters residing in habit, the bai-k, etc. I attempted when in Tasmania to fix upon tlie characters
o f the species that I met with growing there, but I am indebted to Air. Gmm’s valuable notes and information
for far better materials than I could collect myself. Notwithstanding all these advantages, I am iiiucli
puzzled as to the Hmits o f several of tlie species, and can only offer the following monograph o f the Tasmanian
ones as an attempt. I think I have kept separate, as species, quite as many forms as are really so, perhaps more,
and it is very possible that if they were properly studied they would prove much less numerous; but for this purpose
it is requisite that the uaturaHst should have no preconceived ideas o f what is to form a species, and especially
that lie study the individuals in aU soils aud situations, cultivate long, aud propagate them in cultivation.
It is quite certain that all or most of the species have very different aspects at different periods of growth; and as
each aspect is liable to be modified by soil and climate, the limits of variation must be veiy wide. Local cftcum-
stauccs may further favour the prolongation or retardation of that period dming which au individual or aronp of
individuals retains a certain form or aspect, and thus occasion two or more contemporaneous fonns o f one species to
