Name derivation:
Cassytha from  the Greek 'kasytas' or 'kadytas', a name for a parasite which this genus bears a strong resemblance, and thought to have been dodder (genus Cuscuta). Pubescens from Latin meaning downy, short hairs; referring to its pubescent stems and leaves.

Found in the southern part of South Australia, growing in open forest. Also found in Queensland, New South Wales, Victoria and Tasmnia (and New Zealand).
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Weak to robust parasitic twiner with terete stems to 1.5 mm think, striate, pubescent to glabrescent, yellow-green to reddish, younger parts pubescent or woolly, hairs white or red. Leaves reduced, triangular-ovate, to 4 mm long and 2 mm wide, woolly to glabrescent. Inflorescence a single, or often paired spike with 2–10 white flowered, sepals triangular to ovate, pubescent to glabrescent, honey-yellow to brown, black in fruit, petals ovate to obovate, pubescent, hairs mostly grey but sometimes black, yellow or red. Flowering between December and April.

Seed collecting:
Collecting mature fruits, those that are soft, grey, green-grey to green-red and have a hard woody seed inside.
Seed cleaning:
Place the fruits in a bucket of water and rub with your hands to remove the soft flesh. Remove any seeds that are floating. These will be empty seeds. Drain the water and keep only the hard seeds at the bottom. Place the seeds on paper towel and leave to dry. 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.
