I have very few Tasmanian specimens, but they are absolutely identical witb the New Zealand plant, which I
have gathered abundantly.— A small, erect shrub, 2 - 3 feet high, with erect, fastigiate, broom-like branches, densely
vülous with spreadmg hairs. Leaves | inch long, abundant, linear or linear-oblong, blunt, scabrid above, villous
on both sm-faces, most so below, margins revolute generaUy to the co sta ; petiole vei-y short. Stipules subulate,
almost filiform. Flowers in small, axillary, few-flowered cjnnes, which are scarcely longer than the leaves, and very
abimdantly produced along the branchlets. Calyx villous. P eta ls none. Stamens exserted. Antliei-s shortly
oblong. Style three-cleft. Fruit unknown.— In New Zealand specimens the leaves become more expanded, tbeir
margins only recurved, and exposing the woolly under surface of the leaf. Fenzl (Plant, Hiigel. p. 23) says of
this that it is too nearly allied to P . phy lice folia, Lodd. (Bot. Cab. 120).

Tb e affinities o f tb is curious Order are considered to b e w ith FkphorUaceoe on the one hand and
Celastrineæ on th e other ; differing from Fupkorbiaceoe in th e erect seeds, hermaphrodite flowers, and in d e hisc
en t carpels. From Celastrineæ th ey differ in having stipule s, in th e claws o f th e pe tals b e in g united,
and in th e want o f a disc : th ese characters seem to me o f le ss importance than th o se separating Stach-
housieee from Euphorhiaceoe, as they are aU found in th e Order Rhamneæ, except th e absence o f a disc,
which is often present in Euphorbiaceæ. A b o u t fifteen or twenty Australian species are known (Ijut these
are so variable th a t they w ill probably be r educed), chiefly natives o f th e south-we st coast, where th e curious
g en u s Tiipterococcus (of wh ich there are four species) occurs, along w ith six or seven StacJchousieæ. A
few o f th e latter g en u s are trop ica l; one species o f Stackhousia is found in N ew Zealand, and there is
perhaps also a Ph ilip p in e Isla n d one, o f which however I have seen very indifferent specimens.

Of this genus there are four Tasmanian species, some of whicb are far from well marked, and one of
them is very common in open, dry places. AU form erect herbs, with stems branching from the root only.— Zeare«
rather fleshy, alternate, sessile, stipulate, entire, linear or spathulate. Flowers sessile, forming dense or lax spikes
at the ends o f the branches, bracteolate. Calyx smaU, short, broadly campanulate, five-lobed. Petals five, seated
on tbe throat of the calyx, with long, erect, free or connate claws, and small spreading limbs. Stamens five, two
alternate filaments longer than tlie others. Ovary three- to five-lobed, with as many cells, and a style divided
above into as many stigmatiferous lobes. Ovules solitaiy in the cells, erect, anatropous. Fruit of three to five
crustaceous, indehiscent cocci, separating from a central axis. Cocci one-seeded. Seed erect ; testa membranous.
Albumen fleshy. Fhnhyo straight, with the radicle towards the hilum. (Named in honour of J . Stackhouse, an
English botanist.)

Much the tallest Tasmanian species, 6 inches to 2 4 feet high, often much branched from the very base.—
Boots fibrous or creeping. Branches erect, slender, sometimes divided. Leaves 1 -3 inches long, Unear or lanceolate
or Unear-spathulate, very variable in breadth, acute or acuminate, fleshy, one-neiwed or nerveless. Spikes 1 -6
inches long, 1 inch in diameter, much narrowed at the apex before the flowers are fuUy expanded. Flowers spreading,
sweet-scented, white or cream-colour, i - r inch long, variable in breadth; bracts generally longer than the calyx.
Immature cocci (in dried specimens) have the surface wrinkled.
2 . Stackkousia Gunnii (Hook, fil.) ; humilis, robusta, radice repente, caulibus plerumque solitariis,
foliis carnosis linearibus lanceolatis lineari-spathulatisve enerviis, floribus fiavidis, spicis apice obtusis
conicisve. {Gunn, 1 0 4 8 .)

I have retained this species in deference to Mi-. Gunn’s opinion, who has repeatedly studied it, aud assures
me that though so sunUar to S. monogyna, it is always truly distinct. The differences he indicates are, the smaller
size, more robust habit, more creeping root, generally solitary stem, blunter spike, and deeper cream-coloui-ed or
yellowish flowers. He adds that it is also a perennial, None o f the above characters are at aU satisfactoiy to me,
and much diminished in value from the plant affecting only certain soils, that tend to produce creeping roots and
short stems and fleshy habit. The roots of S. monogyna appear to me to be perennial, and Gimn remarks that they
creep sometimes ; the flowers too o f that plant vary much in shade o f white and cream-colour. Mr. Adamson,
wlio sends S. Gunnii from Melbom-ne, says that the flowers have a disagi-eeable odour.

This is a remarkably fine species, and well distinguished by the habit, foUage, flowers, aud curious fruit ; the
latter however I have only seen in Australian specimens, aud in these it never varies, whereas in diflereut iniUviduals
from various parts of that continent (Port Stephens, Moreton Island, Port Jackson, and South Australia) the leaves
differ in breadth, the spikes in length and breadth, the flowers iu size and colour, aud the calj'x-lobes in breadth
and size.— A diffuse species, branching from the base and spamigly iqjwards. Boot perennial. Stems ascending,
stout. Leaves rather fleshy, more or less spathidate, generally broadly so, acute, apiculate, ot blunt, 4 - I 4 inch
long. Spikes short and broad, 1 4 -2 inches long, 1 broad. Flowers cream-coloured, witb orange and red spots,
