Leaves flat or concave, with flne or pungent points. Bracteoles on the 
calyx-tube. Flowers pedicellate. Glabrous or pubescent. Leaves broad, 
flat or slightly concave, all in threes 0. P. ternata. 
(A very few species of the following section have the leaves occasionally irregularly whorled, 
but with the calyx-lobes much less dissimilar. A few species again have the calyx of Euchilus, 
but with the leaves all alternate.) — Bentli. 
Sect. III. Coelophyllum . — Leaves all alternate, either flattened hut more or less concave, 
or ivith incurved margins, or darker-coloured underneath than above, or, if linear-terete or 
trigonous, channelled above, 1 or 3 -nerved or quite nerveless, without transverse veins or reticula- 
tions . — Benth. 
Leaves terete or trigonous, not pungent, channelled above. Stipules united at the base within 
the leaf, at least on the young shoots. Flowers in dense terminal heads . — Benth. 
Bracteoles close under the calyx, but free from it. Leaves crowded, in- 
curved, with fine points 10. P. ecliinula. 
Leaves concave or nearly flat, rarely terete and then rigid, but not pungent. Flowers axillary, 
or, if terminal, solitary or in small leafy heads growing out into leafy shoots. Bracteoles inserted 
on or adnate to the calyx-tube . — Benth. 
Flowers sessile or nearly so, all axillary. 
Calyx 2 upper lobes much longer than the others, broad, falcate and 
united to the middle. Leaves linear-terete or trigonous, channelled 
above 12. P. setulosa. 
Calyx 2 upper lobes but little longer than the others. Leaves small, 
oblong-cuneate, obtuse 11. P. parviflora. 
Flowers all axillary, pedicellate. Stipules small. 
Plant more or less villous. Pedicels short. Leaves small, mostly 
obtuse, 2 to 4 lines long or rather more, broad or narrow 13. P. villosa. 
Plant glabrous. Leaves J to lin. long 14. P. flexilis. 
Leaves concave or nearly flat, not pungent. Floivers axillary, or, if terminal, solitary. 
Bracteoles inserted close under the calyx, but free from it. — Benth. 
Plant quite glabrous. Flowers all axillary. Leaves Jin. long or more. 
Flowers pedicellate. Calyx upper lobes large 15. P. euchila. 
Plant pubescent. Flowers axillary. Leaves 4 to 7 lines long. Flowers 
on very short pedicels. Calyx rosy-white 16. P. Millari. 
1. P. retusa (obtuse), Sin. in Ann. Bot. i. 502, and in Tram. Linn. 
Soc. ix. 247 ; Benth. FI. Austr. ii. 113. A shrub with slender virgate branches, 
often angular and usually silky-pubescent. Leaves linear or linear-cuneate, 
very obtuse or more frequently emarginate, and sometimes dilated at the 
end, 2 to 4 lines or rarely Jin. long in the normal form, flat, pale underneath, 
but usually glabrous on both sides. Stipules very small. Flowers few, in small 
terminal heads sessile within the last leaves. Bracts imbricate, the inner ones 
often 1J line long, but very deciduous, the outer ones smaller. Bracteoles 
broadly linear, inserted on the calyx-tube. Calyx about 2 lines long, silky-hairy, 
the 2 upper lobes broader, but scarcely more united. Standard not twice as long 
as the calyx. Ovary villous ; style filiform almost from the base. Pod broadly 
ovate, almost triangular, about 3 lines long, rather flat. — DC. Prod. ii. 112 ; 
Bot. Mag. t. 2081 ; Bot. Reg. t. 378. 
Hab.: Shoal water Bay, R. Brown; Glasshouse Mountains and Brisbane Kiver, F.v. Mueller; 
and other localities in southern Queensland. Flowering in July and August. 
Some specimens without flowers, from Burnett River, Queensland, F. v. Mueller, appear to be 
nearly allied to P. retusa, but with very narrow leaves, almost terete, with closely revolute 
margins. — Benth. 
2. P. pycnocephala (dense flower-heads), F. v. M. Herb.; Benth. FI. 
Austr. ii. 114. Branches and under side of the leaves silvery-white with a soft 
dense silky pubescence. Leaves broadly obovate, obtuse or with a short recurved 
point, 3 to 4 lines long, coriaceous, glabrous smooth and shining above, the 
margins slightly recurved. Stipules appressed, nearly 1 line long. Flowers in 
dense globular heads, sessile above the last leaves. Bracts imbricate, broad, 
densely covered with silky hairs, except a narrow margin. Calyx sessile, nearly 
4 lines long, very silky, the lobes narrow, acute. Bracteoles narrow-cuneate,
