acuminate, sometimes linear-subulate, finely ciliolated, pale at the margin. Petals cyan-blue, very rarely 
pink or white, glabrous, oblong- or elliptical-obovate, tapering into a cuneate base, minutely cuspidate at the 
apex, three-nerved along the middle, veined, J—1 inch long. Filaments 1-1J line long, subulate, considerably 
thickened towards the hase, glabrous, often blue. Anthers not oscillating, affixed at their basal sinus to Hie 
filament, 1J-2J lines long, oblong with cordate base, bending to that side of the flower opposite to the pistil. 
Style thin-filiform, at first about 1 line, finally nearly 2 lines long, slightly curved or uncinate. Ovary 
glabrous, tapering into an extremely short stipes. Capsule subsessile, j-f inch long, grey-fulvous, opaque 
outside, polished inside, bursting- in age half downward along the middle nerve of the valves and separating 
also finally along the septum almost completely into its carpellar portions. Funicles very short. Seeds 
brown, shining. 
In flower during the spring.

Sepals free. Petals more or less coherent into a tube, unguiculate. Filaments elongate, sur¬ 
rounding the pistil Anthers free, bursting longitudinally. Style generally long, setaceous. Stigma 
minute, bilobed. Capsule parchmentous, two-celled, slightly compressed, with loculicidal and some¬ 
times also septicidal dehiscence. Seeds several or many in each cell, dry, turgid or somewhat com¬ 
pressed, wingless. 
Elegant climbers, all, with exception of M. bignoniaceus, natives of Western and South-Western 
Australia. Leaves alternate, herbaceous or subcoriaceofis, entire, sometimes partially toothed, never 
very narrow; flowers terminal and axillary, cymose, less frequently solitary, twin or ternate. Petals 
white, yellowish, orange or red, sometimes beautifully streaked or dotted.— Putt. Syn. Pitt. 22 ; Calo-

Marianthus is brought through the analogous structure of its fruit into close relationship ivith 
Cheiranthera, from which in general the habit and more especially the corolla and stamens render it 
distinct. Homalosporum may either he regarded as a subgenus of Marianthus, or, chiefly on account 
of its perfectly flat seeds, as generically distinct. Billardiera agrees with Marianthus in the flowers, 
but differs widely in*'its baccate fruit.

Branches downy, at first silky, at last smooth; petioles rather short; leaves herbaceous, ovate, oblong 
or lanceolate, with cordate base, above glabrescent, beneath somewhat hairy; pedicels axillary, solitary, 
twin or ternate, about as long as the calyx or twice as long; flowers pendulous; sepals downy, lanceolate, 
acuminate, several times shorter than the corolla; petals orange-yellow, coherent to near the apex into a 
straight cylindrical slightly hell-shaped corolla, rather blunt, somewhat downy; filaments setaceous; anthers 
cordate-ovate; ovary silky; capsules narrow-elliptical, downy, many-seeded; seeds glohose-ovate, turgid. 
On umbrageous rivulets, spring-s and cataracts, and also in fissures of irrigated rocks in the Serra and 
Victoria Ranges and the Grampians. Further only known from the shady hanks of the Onkaparinga and 
from the Mount Lofty Ranges in South Australia; nowhere frequent; ascending to elevations of 5000 feet- 
Root filiform, tortuous', with distant fibres. Stems often several feet long, slender, covered with a 
brown membranous periphlaeum. Petioles 2-6 lines long, downy. Well-developed leaves f-3 inches long, 
one-nerved, finely veined, somewhat paler and opaque beneath, more densely downy at the margin, which in 
age is often revolute; the lower one sometimes quite cordate. Bracts several at the base of the pedicels, 
about 1 line long, ovate- or linear-lanceolate, acuminate, silky-downy at the back. Bracteoles wanting or a
