deep terminal sinus. Stamens 3-25, with filaments either almost free, or beyond the middle united. Anthers 
oblong, equal to or exceeding the length of the filaments with evidently introrse dehiscence. Styles compa¬ 
ratively short. Carpels 1-2, outward somewhat downy, inward glabrous, nearly as long as the calyx. Seeds 
oblique ovate-globose, slightly compressed, 1 line long, nearly black, shining, often for the greater part 
enclosed in the arillus. 
P. nitida, R. Br ., which extends perhaps to the eastern part of Gipps Land, differs chiefly from P. 
ovata in sessile flowers and in the form and smoothness of the sepals. 
Some marked forms of P. ovata may be distinguished as varieties; for instance, a small flowering one, 
growing in swamps, producing but few stamens and small generally velvety leaves; a rough-leaved more 
glabrous trailing variety, occurring’ in the underwoods of forests; and a large-leaved form, more frequently 
to be found on or near the coast, remarkable for its conspicuous flowers with monadelphous numerous stamens. 
A copious set of specimens in our collection shows, however, the above notes as of no avail for specific 
discrimination. Dr. Hooker’s researches in this genus have realized similar results. 
Hibbertia densiflora. —Pleurandra sericea, R. Br. in Cand. Syst. i. 416; P. cinerea, R. Br. 1. c .; 
P. densiflora, Hook. Journ. of Bot. i. 245. 
A low strictly erect or ascending shrub; leaves linear - or cuneate - or lanceolate-oblong , with recurved 
or revolute margin, and a strong midrib, hirsute, pubescent, velvety or scantily downy, or above glabrous, 
floral ones crowded; flowers hardly as long as the leaves, sessile or on very short peduncles, several at the 
summit of the branchlets, rarely solitary; sepals liirsute-silky; ovaries 2, velutinous; carpels 2-3-seeded; 
arillus feshy, less than half as long* as the seed, hardly sinuate. 
In sandy heathy plains, on barren scrubby ridges, and occasionally on rocky ranges; from the Glenelg 
to the Murray River and its tributaries, and thence to Port Phillip; on Putter’s Range, on granite ranges on 
the Broken River, &c. Pound also in the south-eastern part of the colony of South Australia and in Tasmania. 
Height from a few inches to 2 feet. Branches rather robust, tomentose- or villose-pubescent, towards 
the summit more silky or hirsute. Leaves coriaceous, rarely ovate, subsessile, J-l inch long, 1-2 lines broad, 
scarcely acute, the floral ones often increased in breadth; their nerve above impressed, beneath strongly 
prominent and rarely touched by the recurved margin of the leaf. Peduncles stout, 1 line long or obliterated. 
Flowers several or solitary, terminal, without scent. Sepals 3-4 lines long; outer ones lanceolate, inner ones 
ovate with petaloid margin, the former outside densely, the latter only along the middle part silky-hirsute. 
Petals obcordate-cuneate, about twice as long as the calyx. Stamens 7-20. Pilaments shorter than the 
anthers, connate at the base. Anthers oblong, nearly 1 line long, with distinctly introrse dehiscence. Styles 
1| line long, incurved. Carpels about 3 lines long. Seeds brown, oblique ovate-globose, 1 line long. 
Arillus livid, cupular, subsinuate or repand, not or only towards the margin membranous. 
The description of the fruit is furnished from a specimen g-rown on granite rocks at the Broken River. 
This species is generally well recognized, but there exist certain forms of it which render its discrimi¬ 
nation from Hibbertia stricta somewhat difficult. 
Neither of the specific names adopted by R. Brown for this species applies well to its normal form.

An erect, spreading or prostrate shrub; leaves linear , rather blunt , scabrous, smooth or velvety or 
clothed with scattered starry hair; their margin repressed; flowers sessile or short-stalked rarely long- 
stalked bracteate; sepals lanceolate or inner ones ovate; petals obcordate; stamens-5-20; ovaries 2-3, velvet- 
tomentose; carpels 1-2-seeded; arillus membranous, about half as long as the seed, lobate or truncate.
