Distribution:
Found in the north-eastern part of South Australia, parasitic on various herbaceous species such as Tribulus, Calotis, Sida, Boerhavia and other forbs in open woodlands and shrublands in arid to semi-arid regions, often along waterways and in swampy areas and gibber plains. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Uncommon in New South Wales. Common in the other states.

Parasitic twining herb with slender, pale brown stems. Inflorescent in dense clusters with 4 yellow flowers. Flowering between March and May.
Fruit type:
Golden depressed-globular capsule to 4 mm diameter.
Seed type:
Orange globular seed to 2 mm diameter.
Embryo type:
Folded.
Seed collecting:
Collect capsules that are maturing, turning brown and contain hard seeds inside. 
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
