Lysiosepalum abollatum is an erect, dense shrub that typically grows up to 1.5 m (4 ft 11 in) high and wide, and has most parts covered with white, woolly, star-shaped hairs.

[4][6] The specific epithet (abollatum) means "a robe of thick, woolen stuff, worn by soldiers and philosopheers", referring to the woolly appearance of this species.

[4] Woolly lysiosepalum has a very restricted natural range; they are found only in the Wongan Hills area of the Avon Wheatbelt IBRA bioregion, some 180 km north-east of Perth, in south-west Western Australia.

[1] The species has been listed as Critically Endangered under Australia's EPBC Act and as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is in danger of extinction.
