It is hoped a rare Tasmanian heath could provide a solution for a cinnamon fungus which is attacking the state's plants.

Botanists from the Tasmanian Government and Kew Gardens in England have collected seeds from a heath in the Furneaux Islands in Bass Strait.

Principal botanist at the Department of Primary Industries, Stephen Harris, says the heath seems to be resistant to the fungus and it could eventually provide a treatment.
"Because it's rare we don't know a lot about the ecology of the plant, we don't know a lot about its seed," he said.
"We've taken the seed from the stronghold of its distribution in the Furneaux [Islands and] we'll be able to find out more about it and understand what sort of factors are at play in its ecology.
