[ Pimelca . 
S. P. glauca (grey), R. Br. Prod. 360; Bent/i. FI. Austr. vi. 15. An 
erect much-branched shrub, from A to l^ft. high, glabrous except the inflores- 
cence. Leaves opposite, from ovate to oblong-lanceolate or almost linear, 
sometimes all under Ain., sometimes f to fin. long, or even longer, flat or 
concave, with the midrib prominent underneath. Flower-heads globular ; 
involncral bracts usually 4, ovate or ovate-lanceolate, shorter than the perianth, 
sometimes not much, sometimes considerably broader than the stem-leaves, the 
inner ones ciliate on the margin and more or less silky-hairy inside. Receptacle 
densely covered with long hairs. Perianth-tube 4 to 5 lines long, circumsciss 
after flowering considerably above the ovary, the persistent portion rarely 
glabrous or sprinkled only with hairs, the deciduous portion silky-villous, the 
lobes about 1A lines long. Filaments usually half the length of the lobes ; 
anthers oblong, with a narrow connective. Fruit sessile or nearly so within the 
perianth, the epicarp membranous. Seed not seen perfectly ripe, but the 
cotyledons appear to be rather broad. — Meissn. in DC. Prod. xiv. 501 ; Rudge in

This species is sometimes confounded with the P. linifolia, the most ready distinction is in the 
persistent base of the perianth being nearly glabrous but half concealed by the long hairs of the 
receptacle. The leaves are also usually concave when dry, but this distinction cannot always be 
safely relied on. — Benth. 
4. IE*, collina (of hills), R. Br. Prod. 359 ; Benth. FI. Austr. vi. 16. 
An erect shrub, glabrous except the inflorescence, closely resembling P. linifolia, 
but the leaves are slightly concave with the lateral veins more prominent 
underneath, running into a marginal nerve when the leaves are narrow, more 
pinnate when the leaves are broader, the involucral bracts are also usually more 
rigid and prominently veined. It differs from the narrow leaved forms of /'. 
ala ut-a, in the involucral bracts being glabrous inside as well as out, the short 
hairs to the receptacle, and the perianth usually villous from the base. — Meissn.

5. 3P. linifolia (Flax-leaved), Sm. Bot. N. Holl. 31, t. 11 ; Benth. FI. Austr. 
vi. 17. An erect shrub, from under 1ft. to 2 or 3ft. high, glabrous except the 
inflorescence, the branches usually slender and virgate. Leaves opposite, on 
very short petioles, linear or oblong, passing also into linear spathulate or linear- 
lanceolate, from under Ain. to about lin. long, nearly flat, the margins in the 
dry state usually slightly recurved and rather convex than concave. Flower- 
heads terminal, globular, erect ; involucral bracts 4, ovate or ovate-lanceolate, 
often nearly as long as the flowers, glabrous inside as well as out, rather thin, 
the midrib not very prominent. Receptacle shortly villous. Perianth-tube 4 to 
6 lines long, silky-villous from the base, circumsciss rather above the ovary, the 
lobes 1 to 1 A line long. Filaments usually about half the length of the lobes; 
anthers oblong, with a narrow connective, the cells when opened placed back to
