PLANTS INDIGENOUS TO 
[Dilleniocece. 
In sandy rocky or heathy localities of the lowlands and hills not rare. It extends also all over 
Tasmania and to Spencer’s Gulf, and through New South Wales, as far as the tropic of Capricorn, and 
seemingly also to the west coast of Australia. 
A bush of variable habit, from a half to several feet high. Blanches angular, glabrous or short-downy. 
Leaves g*enerally spreading, coriaceous or herbaceous, short-stalked, rarely acute, never mucionate, g 1 inch 
long-, i_l line broad; the edges closely revolute into a narrow margin, the interstice between the margin 
forming a broad flat keel, rendering thereby the lower side of the leaves apparently bistriated; surface 
nerveless. Cicatrix bearded. Blowers mostly terminal, when sessile bracteate by a few diminutive leaves, 
when stalked furnished at the summit of the peduncle with a solitary bracteole of the form but not folly of 
the size of the leaves. Peduncles reflexed in age. Flowei*s inodorous. Sepals about £ inch long, generally 
acute, at last spreading; the outer ones lanceolate, the inner ones ovate, often bearded at the apex, smooth or 
powdery downy, or less frequently silky. Petals surpassing* but little or half the length of the calyx. Stamens 
free or connected at the base. Anthers oval or oblong, blunt, broader towards the base, §-l line long, with 
decidedly introrse dehiscence. Pollen-grains ellipsoid, with very blunt extremities, bursting by a longitu¬ 
dinal slit. Styles about 2 lines long, in age inflexed-uncinate. Carpels varying in length according to their 
number of seeds. The latter ovate-globose, somewhat compressed, dark-brown, shining, hardly 1 line long. 
Arillus closely oppressed. 
Although I enjoyed not the advantage of comparing authentic specimens of those plants which I 
quoted as synonyms of H. stricta, I can hardly entertain any doubt about their invalidity as species. 
P. liypericoides, DC., according to a Preissian specimen, appears hardly specifically distinct. On the 
sterile ranges of the Avon in Gipps Land occurs a variety well responding to the definition of P. calyeina, 
which deserves special notice on account of tall and strict growth, acute leaves and silky calyx; this variety 
resembles strongly certain Pultenseas in habit. 
Hibbertia humifusa.—Pleurandra humifusa, F. 31. Second Gen. Deport, p. 9. 
Stems much branched, procumbent; leaves linear, rather acute, glaucous, with revolute margins, as 
well as the branclilets hirsute; peduncles not much longer than the ebracteolate jlomer; sepals large, broad- 
ovate, hirsute-pubescent, at last connivent.; petals obovate-cuneate, slightly emarginate , hardly as long as 
the calyx; stamens 6-9; ovaries 2, velutinous, with about 6 ovules ; carpels 4—6 -seeded; arillus membranous, 
truncate or toothed, of less than half the length of the seed. 
In barren scrubby plains near Mount Zero. 
Stems numerous, spreading in all directions, about 1 foot long. Leaves crowded, 3-5 lines long, 
tapering into the base and summit, with narrow closely re volute margin, which, however, is not so evidently 
repressed as in H. stricta, although fully or nearly touching* the narrow midrib. Peduncles curved, hirsute- 
pubescent, often below the middle provided with a solitary bract, which is 1J-2 lines long, but deprived of a 
terminal bracteole. Sepals 4—5 lines long, rather acute, inward somewhat velutinous, the outer ones remarkably 
broad. Petals about 3 lines long, not, as in the generality of the species, cleft by a deep or acute terminal 
sinus, nor considerabty upwards dilated. Filaments free, scarcely longer than the linear-oblong anthers. 
Dehiscence of the latter nearly marginal. Ovaries in coalition, with velutinous cavity. Carpels concealed in 
the connivent calyx, with which they form an almost globular fruit. Seeds barely § line long, shining-brown, 
renate-globose. Arillus closely appressed, generally sevei’al times shorter than the seed. 
Allied to H. stricta and H. hirsuta. 
Flowers early in the spring.
