whilst in a specimen gathered near Lake Torrens the leaves are semi terete. If the very 
characteristic black berry of L. Exocarpi is identical with that of L. Casuarina?, we cannot 
hesitate ^ to combine both. L. subfalcatus, according to Sir Will. Hooker’s diagnosis in 
Mitchell s Trop. Austr. p. 224, seems not to differ from L. Exocarpi. A variety with spathulate 
leaves I observed in Arnhem s Land and on the Gilbert River. The species extends with 
several others to the southern shores of Australia Felix, but has not been met with in Tasmania, 
where, singularly enough, no Loranthaceae exist. The flowers are extremely variable in size, 
offering a collateral proof that L. Gaudicliaudii cannot be discriminated from L. pendulus, on 
account of smallness of flowers. The petals are sometimes deep red, sometimes brilliantly 
yellow. It grows on Melaleucas, Acacias, Casuarinas, Exocarpi, Myopora, less commonly on 
Eucalypti, occasionally on other trees, sometimes upon other Loranthi, the same tendency to 
a double parasitism having been noticed in Viscum incanum. The filaments are black, 
occasionally red. 
Loranthus insularum (Asa Gray, in Unit. States Explor. Exped. Botan. 738, t. 98) has 
been found by the author of this memoir on the Gilbert River, and by Mr. Flood on Quail 
Island. The difference of this Loranthus from the preceding one rests chiefly in the ready 
mutual separation of the petals, in the disposition of the flowers, which affords one of the best 
characteristics for discriminating amongst allied species, and perhaps in the color of the fruit. 
The flowers are ternately, seldom more or less in number, sessile on the summit of very short 
racemosely disposed secondary peduncles. The petals are often, if not always, white at the 
summit, and the lobes are marked above the point where the filaments separate with a small black 
spot. The berries are green-brown, variegated with pale streaks. The leaves occur broad- or 
falcate- or oblong-linear, or, as expressed in the quoted plate, ovate, or elliptical- or cordate-ovate, 
and are not rarely sessile. The filaments seem of yellow, at least not of a black color. 
LORANTHUS MAYTENIFOLIIS. 
Asa Gray , in Wilk. Unit. Stat. Explor. Exped. p. 739, pi. 99. 
Of this and two seemingly undescribed species I insert the diagnosis. 
Leaves opposite, broad- or orbicular-ovate, tapering into a very short petiole, faintly or 
indistinctly nerved and veined, very shining above; peduncles solitary or geminate, usually 
2-3-flowered, as well as the pedicels very short or obliterated, and together with the bracteoles 
and calyces thinly covered with brown velvet-downs; calyx twice as long as the roundish brac- 
teole; its limb minutely denticulated; petals 5, red, coherent into a long slender unilaterally 
dehiscent tube ; limb in (estivation broader than the tube and blunt; its lobes narrow-lanceolate, 
short, inside yellow, outside slightly velutinous ; free part of the filaments short ; anthers linear, 
basifixed ; style capillar-filiform ; stigma minute, capitellate ; berry urceolate-ovate. 
On the Rivers Richmond, Hastings and Clarence, Dr. Beckler ; at Moreton Bay, W. 
Hill ; Wollongong, Wilkes’s Expedition. 
Branchlets terete, not unfrequently verticillate. Leaves 1-2 inches long, above dark- 
green, beneath less shining, in age at the margin somewhat recurved. Flowers terminal and 
axillary, crowded into irregular whorls. Corolla about 1| inch long, more or less curved, outside 
slightly silky-downy, especially its limb, lobes hardly 3 lines long. Anthers measuring 1-1 A 
lines in length. Style short-exserted. Ripe fruit unknown. 
LORANTHUS DICTYOPHLEBUS. 
Glabrous ; leaves opposite, ovate, ot oblong- or ovate-lanceolate, narrowed into a short 
petiole, strongly penninerved and net-veined , shining above , paler beneath ; secondary peduncles 
few, lateral, usually three-flowered, forming a cymose corymb; lateral flowers short pedicelled ; 
calyx obconical-cylindrical, with a repand margin, three or four times longer than the orbicular 
bracteole ; petals 6, vitellinous, connate into a club-shaped-cylindrical unilaterally somewhat 
dehiscent tube ; limb in (estivation much narrower than the tube; anthers narrow-linear, basi- 
fixed ; style capillary ; stigma minute, capitellate. 
Illawarra, Shepherd ; Hastings River, Beckler ; Moreton Bay, F. M. 
B.anchlets terete. Leaves thin-coriaceous, flexible and not, as usually the case, brittle 
in exsiccation, 2-5 inches long, |-2J inches broad. Corolla 1£ inch long. Anthers at first 
coherent. Style short-exserted. Fruit as yet unknown. 
The leaves resemble greatly those of L. loniceroides. The contracted apex of the 
alabaster and the inflorescence seem mainly to distinguish our plant. 
LORANTHUS GRANDIBRACTEUS. 
Glabrous ; leaves opposite, narrow- or ovate-oblong, stalked, opaque, slightly 3-5 nerved, 
inconspicuously veined ; peduncles hardly surpassing the length of the petiole, towards the 
summit compressed and dilated ; bracts two , opposite , leajlike , very large , ovate , 5-7-nerved, 
connate at the base, forming a long involucre to the sessile flowers ; berries yellowish, globose- 
ovate. 
Pendent from the branches of Eucalyptus melanopliloia, on several places between the 
Albert and Flinders River. 
Branches cylindrical, compressed at the summit. Leaves 2-4 inches long, 4-8 lines 
broad. Peduncles 6-9 lines long. Bracts opaque, generally \\ inch long, slightly cordate at 
the base, finally indexed at the margin. Flowers unknown. Berry about J inch long.
