olivaceous-black ; 1-2 lines long; shining; smooth or partially tubercled; usually twice as long as the suboyate 
colorless placental membrane. Cotyledons hardly thinner than the radicle. 
C. Lawrenciana forms the smooth-leaved variety of this species; C. ferruginea the variety with tomentose 
leaves. In the u Flora Tasmanica” C. glabra and C. Sclilechtendalii are referred to C. Lawrenciana; while 
undoubtedly they represent glabrous-leaved varieties of C. speciosa; nor can C. leucoclada; which we possess 
from the locality indicated by Sir Th. Mitchell; be drawn to any other species than C. speciosa. C. Lawren¬ 
ciana is; like numerous other plants common to this colony and Tasmania, not indigenous to South Australia; 
hence it is more likely that also the South-Western Australian species, indicated by Dr. Hooker (conf. FI. 
Tasm. i. 62) as probably belonging to C. Lawrenciana, should be referred to C. speciosa, which indeed we 
possess from Major Warburton's collection as far west as Streaky Bay and Venus Bay. Nevertheless it must 
be admitted that the differences between C. alba, C. semula and C. speciosa are greater and more positive 
than between C. speciosa, C. decumbens and C. Lawrenciana; but whilst amongst extensive sets of specimens 
of the latter three plants all middle forms are wanting, we have to regard them as really specifically distinct.

Leaves herbaceous, cordate or orbicular- or lanceolate- or cordate-ovate; pedicels solitary, geminate 
or ternate, slender-filiform, elongated, scantily hairy, jointed, much thickened towards the apex; flowers 
pendulous; calyx lax, herbaceous, scantily hairy, cleft beyond the middle into 4 deltoid or semilanceolate 
long-acuminated lobes ; petals long-persistent, membranous, during anthesis only free at the apex, finally 
separating from each other; tube of the corolla greenish or purplish; filaments short-exserted; those opposite 
the petals broadly dilated towards the base; anthers yellow, nearly thrice as long as broad; style smooth; 
stigmas coherent or slightly divergent; carpels as long as the calyx, oblique-ovate. 
On stony shady and irrigated declivities of the Serra and Victoria Ranges; beyond this colony known 
only from deep rocky well-watered glens of the Barossa Ranges and from the mountains near Encounter Bay. 
A remarkable shrub, several feet sometimes up to 10 feet high, with usually patent branches, which are 
thickly hispidulous-tomentose. Leaves provided with short or moderately long petioles, conspersed on both 
pages with scattered stellate hair, usually from 1-1^ inch long, occasionally fully 2J inches in length, often 
rather acute, undulated and frequently denticulated at the margin, somewhat paler beneath. Pedicels J-l 
inch long, terminating short axillary peduncles, which are provided at the apex with a pair of opposite 
lanceolate, ovate or cordate, always acuminate, foliaceous bracts of 2-4 lines length. Bracteoles placed 
variedly more towards the apex or middle or base of the pedicels, lanceolate- or linear-subulate, 1-2 lines 
long, scattered-hairy. Calyx dark-green, about 4 lines long, scantily clothed with dispersed star-hair; its 
lobes alternate with the petals, divergent. Corolla always of a more or less sordid color, bluish- or purplish- 
grey or pale yellowish-green, more tender in substance than that of its congeners, 1-1J inch long, outside 
covered with minute downs, inside glabrous, partially or often totally separating from each other in age and 
involving a pair of filaments. Filaments greenish-white, finally yellowish, smooth. Anthers yellow, little 
longer than 1 line, almost ellipsoid, with bilobed base. Pollen-grains golden-yellow, ellipsoid, bursting with 
longitudinal slits. Style white-green. Stigmas very minute. Disk short, pale green-yellow, smooth, with 
8 prominent ridg'es. Carpels livid, about 3 lines long, rounded-blunt, bearded at the summit. Endocarp 
pale-yellowish. Seeds and placental membrane similar to those of its cong’eners. Embryo as yet unknown. 
This plant is in flower almost throughout the whole year, and may be readily multiplied by cuttings.
