A very distinct species, weU marked by tbe long silky haks on the foHage and sepals, aud dense villous to-
meutum o f the branches.— rigid, erect, stout, 4 - 2 0 inches high. Branches erect, lower parts clothed with
steUate pubescence, upper with long, silky, often compound, haks. lea v e s Unear-oblong, ^ inch long, 1 -4 lines
broad, blimt, generaUy narrow, with the margins revolute to the midrib, at times broad, with the back o f the leaf
exposed, and a stout broad midrib ; under surface, except the midrib, covered with dense appressed tomentum,
upper punctate at the base o f the long haks. Mowei-s large, i ineb broad, conspicuous, sessile amongst the leaves.
PeiaZa lobed to one-tlikd the way down. Stamens about eight. Carpels two (one, according to DC.), densely covered
with appressed down. Ovules fom-. Seeds two, with a deep brown testa and smaU-lobed aril.— Brown’s P . cinerea
appears to be a state of this, according to specimens in the British Museum.

Apparently an extremely variable plant, whose forms I have felt repeatedly incHned to separate into two
species : one, the slender, prostrate, or subscandent twiggy plant, o f the southern parts o f tbe Island ; the other, the
stout erect shrub from Fhnders’ Island and the Tamar River. I however find no difference whatever in the flowers
and fruit o f all these varieties ; the leaves vary similarly in each in form, size, and amount o f scabridity and of
stellate hairs on' both surfaces ; and amongst Australian specimens there appear to be still other states tbat do
n ot accord in habit with any of the Tasmanian ones. This species breaks down the principal character upon
which De Candolle founds his divisions Alyssoidece and Eibbertianee. Sieber’s P . parviflora (from Sydney ?) seems
the same as this, and differs from Brown’s species in the leaves not being tomentose below. The P . scabra (Br.
m DC.) does not seem to differ from ovata except m the subglabrous calyx, and leaves subcanescent below ; for I
find the calj-x to vary much in its hairiness, the leaves (as mentioned above) in the amount of clothing below, '
whilst the third character, founded on the supposed pilose ovaries, appears to me to be a misconception, all the
specimens having densely-vOlous ovaries, which is possibly what Labillardiere meant by the term pilose.
Stems 1 -3 feet long or high ; prostrate, slender and twiggy, with distant leaves, in var. a ; erect, stout, and leafy,
in 0 ; bark red, more or less pubescent, or with a few long haks. Leaves inch long, obovate or linear-obovate
and spathulate, rarely linear-oblong or broadly oblong, blunt, contracted into a very short petiole; upper surface
coveretl with more or less copious white tubercles of various sizes, from wliich white set® spring; margins strongly
revolute, seldom reaching the midrib b elow ; under sui-face studded ivith innumei'able orbicular stomata, giving a
whitish or glaucous hue to the broader leaves, also more or less covered with scattered, simple or stellate, very short
setul®; midi-ib pilose. Peduncles slender, pubescent, as long as the leaves. Sepals pubescent, and more or less
pilose. Flowers inch in diameter. Pe tals broadly ohcordate, two-lobed, ivith a deep sinus. Stamens ten,
often monadelphous at the base. Carpels two, very v illo u s; ovules four in each. Seed half-enveloped in a Large
cup-shaped membranous ark.

An extremely abundant and variable plant, wbich I have in vain endeavom-ed to divide into forms distinguishable
by any constant characters. I believe it to be also very common iu Australia, and probably described under
several names. The monadelphous filaments are certainly no character, all th e forms having all, or some o f them,
more or less combined at the base, or quite fi-ee; and De Candolle’s section Candolleance, founded on this cbaracter
(and which was hence made to include the var. stricta), falls to the gi’ound. The variations o f the foliage o f this
species recall those of Leucopogon ei-icoides. Liudlcy’s P . incana, from the stei-ke interior o f South-eastern Australia,
collected by Major Mitchell, appears to be a very hoary state wbich is also found at Port Phillip (F. iMulIer),
and marked as a variety of P . stricta. Jlr. Gunn M'arns me, that if I can find 110 botanical characters to cbstinguish
the different states of this plant -which he sends, I may consider them the same, for tbat it is one of tbe most
variable plants in the Colony. AR the varieties, he states, may be foimd near Georgetown.— Stems woody at the
base, m th erect 01- decumbent slender branches, 4 inches to 4 feet long. Leaves | inch long, very narrow, linear,
b lu n t; margins recm-ved to the midrib ; above smooth and shining, or more or less scabrid, with minute set® rising
from a conical b a se ; tliese are sometimes so munerous as to render tbe foliage hoary. Flowei-s sessile at the ends
o f the branches, rarely shortly peduucidatc, inch across. Stamens usually sei'en. Ovaries two, as in P . ovata.
