Lysiana subfalcata

Lysiana subfalcata is a smooth mistletoe with no hairs on its branches, leaves or flowers.[8] The leaves are oblanceolate, mostly grey-green, 20–120 mm long and 4–20 mm wide, and do not always have a midvein.[8] The paired flowers have an unlobed or weakly lobed calyx and a corolla which is 25–50 mm long.[8] The mature corolla is red, rarely yellow, and sometimes green or black tipped.[5] The fruits are indehiscent, succulent, yellowish and 8–14 mm long,[8] usually pale and somewhat translucent.[5]

Lysiana subfalcata is distinguished from other local (Northern Territory) species of Lysiana by the combination of its oblanceolate leaves, its non-winged pedicels, the paired flowers on a common peduncle, its non-septate anthers, the largely red corolla tube with green or yellow lobes, and the yellowish fruit that are longer than wide.[8]

Lysiana subfalcata can be confused with Lysiana spathulata, but L. spathulata has broader leaves, septate anthers, and a slightly different host and habitat range.[8]

It is found in open forests and woodland.[5][6] However, the Northern Territory flora website describes it as occurring on rocky or gravelly ranges, on hills or rises, on sandplains, and on intermittent watercourses and run-on areas.[8]

Major hosts for Lysiana subfalcata in Western Australia are species in the genera Lysiphyllum, Eucalyptus, and Acacia,[7] while in South Australia, and New South Wales (and for Australia) they are listed as species in the genera Atalaya, Heterodendrum, Bauhinia, Santalum and the family Casuarinaceae.[4][6][5] Hosts in the Northern Territory are listed as including species of Acacia, Alectryon, Atalaya, Capparis, Eucalyptus, Grevillea, Pittosporum, Senna and Vachellia.[8]
