PLANTS INDIGENOUS TO 
[Eutacea. 
Hutt River, and thence known to exist eastward as far as East Mount Barren; but most probably also 
scattered over the country inland along* the Great Australian Bight. 
A singular species, like all those of wide distribution, subject to multifarious variations, producing 
flowers already in the first and second year of growth, and thus assuming the appearance of an herbaceous 
plant, resembling more an Eriostemon than any of its congeners. Root livid, perpendicxdar, after some 
years’ growth stout, flexuose, in seedling specimens filiform and generally undivided. Stems erect or 
ascending, from a few inches to a few feet long, generally slender and towards the base quickly denuded of 
leaves, opposite-branched, unless simple in smaller specimens, not less frequently, together with the leaves 
pedicels and calyces, velvet-downy than glabrous. Leaves of thick more herbaceous than coriaceous consis¬ 
tence, from 1J-8 lines long*, generally from |-1 line broad, occasionally more dilated, often erect, never very 
much spreading; the lobes, when produced, similar to diminutive leaves. Pedicels 1-3 lines long, with two 
bracteoles, which resemble small leaves, and are generally oblong or oval and 2 lines long. Sepals 1-2 
lines in length, oftener blunt than acute, appressed as in most species. Petals membranous, long persistent, 
convolute-imbricate in aestivation, not so much spreading as those of many other species, downy alon°* the 
outside prominent midrib or perfectly smooth, broad- or rhomboid- or orbicular-ovate, 2-4J lines lon°*, blunt 
and generally apiculate, throughout or partially tinged with blue of a dark or pale shade, often gTeenish 
towards the midnd, slightly attenuated yet hardly ung-uiculate at the base. Filaments f-li line long, more 
or less glandulous at the apex; the sepaline ones a little longer than the rest. Anthers pale, fine long, 
ovate-cordate, fixed above the base; their white appendage somewhat turgid, blunt and rather variable in 
size. Pollen yellow. Ovary glabrous. Style J-l line long, glabrous or towards the base downy, split into 
its four component parts after anthesis. Stigma somewhat broader than the style, depressed. Carpels 2-3 
lines long, oblique-ovate, blunt. Endocarp yellowish, nerveless, with a small basal tooth. Placental mem¬ 
brane cordate-deltoid. Seeds i-H line long, black, opaque, subreticulate-asperous, as in most species more 
turgid towards the base. Testa crustaceous. Embryo cylindrical, generally nearly as long as the albumen, 
m rare instances only half as long. 
Cyanothamnus ramosus (Ldl. Swan Riv. Bot. 78), from which C. anetliifolius and C. tridactylites 
appear not to be specifically distinct, seems according to its brief diagnostic note only to be a state of B. 
ccerulescens with biternate leaves, analogous to the corresponding variety of B. polygalifolia. 
ERIOSTEMON. 
Smith, in Transact. Linn. Soc. viii. 285. 
Calyx five-toothed or five-cleft or consisting of five sepals, very rarely four- or six-cleft, imbricate 
in aestivation, persistent, rarely obliterated. Petals 5, rarely 6 or 4, sessile or short-unguiculate, imbri¬ 
cate or valvate in praeflorescence, persistent or deciduous. Stamens 10 , very rarely 12 or more, all 
fertile, those opposite the petals shorter. Filaments free or seldom coherent, linear- or lanceolate- 
subulate or filiform, very rarely subclavate, generally straight at the apex. Anthers dorsifixed or 
basifixed, with longitudinal dehiscence. Ovaries 5, rarely 3 or 2, inserted on an undivided disk. 
Ovules affixed to the interior angle of the ovary; the upper one ascendent, the lower one descendent. 
Styles united into one. Stigmas entirely or partially connate, rarely free. Carpels 5 or seldom 
noimally - oi 3, biusting along the internal edge, 1- or 2-seeded. Endocarp cartilaginous, bivalved, 
operculate towards the base by the placental membrane. Seeds oblique-ellipsoid or subovate. Testa 
crustaceous. Embryo cylindrical, placed in the axis of the copious albumen. Radicle longer than the 
plane-convex cotyledons or nearly as long. 
Strong-scented shrubby rarely suffruticose or arborescent plants, rather numerous in extratropical 
Australia, not rare in Tasmania, scarce in tropical Australia and New Zealand, glabrous or lepidate or
