PLANTS INDIGENOUS TO 
[Rutacece. 
petals white or partially pink, downy; stamens nearly as long as the corolla; filaments woolly; anthers 
minutely appendiculate; style cylindrical, glabrous; stigma minute, five-lobed; ovaries downy at the 
summit-, carpels ovate-rhomboid, rostrate; endocarp saccate at the base, with almost renate or cuneate 
valves; placental membrane cordate-orbicular; seeds grey-black, not or slightly shining. 
As well in arid rocky ranges as in barren scrub land; thus in the Murray desert and in the Grampians; 
in South Australia, near Lake Torrens, towards the Gawler River, and on the cataracts near Mount Lofty; in 
Western Australia near the Fitzgerald River; in New South Wales on the Macleay, Hastings, Darling 
and Lachlan River, on Mount Murchison, on Peel’s Range; in Queensland, near Warwick, according to 
Dr. Beckler, near the Burnett and Dawson River; further, according to Sir Th. Mitchell, close to the 
Mantua Downs; found also by Mr. W. Hill near Wide Bay. 
A numerously almost dichotomously branched shrub, singular for its copious granular exudations, a 
few seldom many feet high. Branchlets almost cylindrical, slender. Petioles generally less than § line 
long, narrow, usually accompanied at the base with two very minute either more scarious or more glandular 
stipular organs of black-brown color. Leaves, when fully grown, from 1J-8 lines long, of a vivid green, 
often shining-, excessively variable in form, either somewhat club-shaped and concave above and convex below 
or subovate or oblong and perfectly flat, or by reduced width merely cylindrical with a slight furrow below, or 
when small assuming by great glandular turgescence a somewhat rhomboid form, not rarely by having the 
margin tumid becoming concave beneath, the glandular protuberances at the edge forming blunt teeth the 
midiib only faintly visible in the fiat-leaved variety. Peduncles none. Pedicels rather slender, upwards not 
much thickened, 1-6 lines long, usually short-downy. Sepals measuring about 1 line, not so much concrete 
at the base as in many other species. Petals ovate-lanceolate, somewhat keeled, acute, almost velvet-downy 
with exception of the dorsal part, not much spreading, imbricate in aestivation, white, often with rose-colored 
back and margin, 2-3 lines long, sometimes outside entirely glabrous, sessile. Filaments linear-subulate, 
white, clothed densely at the margin with crisp downs, which are longer in its upper than lower part. 
Anthers J-J fine long, subcordate, with a white blunt turgid glabrous apex, oscillating in age. Pollen 
orange-colored. Style about 1 line long, five-furrowed, concealed by the wool and within the apex of the 
connected ovaries. Stigma five-lobed by the imperfect coherence of its constituent parts, free in age, glabrous, 
spreading, line long. Disk narrow, depressed, smooth, crenulated. Ovaries always bearded at the top. 
Carpels 1J-2J lines long and not much less broad, rather turgid, somewhat dotted, faintly ribbed, terminated 
suddenly into a subulate more or less erect or divergent rostrum, which is nearly 1 line in length or in various 
degrees shorter. Endocarp livid or pale greenish-yellow, toothless at the concave base. Placental membrane 
about half as long as the seed; of the latter one or two contained in each cell; if solitary of renate-ovate 
shape, if two assuming an oblique-truncate form by mutual pressure, one placed above the other. Testa 
fragile, crustaceous. Endopleura livid, membranous. Embryo very slender. Cotyledons shorter than the 
radicle. 
Authentically named specimens of E. rhombeus have been compared in Sir Th. Mitchell’s collection; 
the E. brevifolius, found by All. Cunningham at the base of Peel’s Range, seems, according to Endlicher’s 
short phrase of this species (in Hueg. Enum. 16), only another form of this singularly inconstant plant, 
remarkable for having* the leaves downy beneath. 
The narrow-leaved variety of E. diftormis bears great resemblance to Philotheca Australis, a plant 
which has, as pointed well out by A. Cunningham already (conf. Field’s New South Wales, p. 330), but 
slight claims to generic distinctions on account of its stamens being downward permanently connate, and 
which indeed has been described by Graham (in the New Edinb. Phil. Jour. xvi. 175) as Eriostemon 
° ci is. Contiasting the latter as a species, it will be found, that its leaves are always semicylindrical and 
very slightly scabrous-downy, that the flowers are constantly very short-stalked and oftener a few arising 
-om one point, that the petals are purplish-pink, short unguiculate and frequently larger, that the filaments 
e ow the middle glabrous and concrete into an liyalinous turgid tube, that the style attains a greater
