Reboulia
Reboulia
Genus of liverworts
Reboulia hemisphaerica, the hemisphaeric liverwort[2] or small mushroom-headed liverwort,[2] is the only species of liverwort in the genus Reboulia.
A possible second species Reboulia queenslandica (Stephani) M. Hicks was published in 1992,[3] but it was later determined to be a polyploid cross between two varieties of R. hemisphaerica, so not a distinct species.[4] Subsequent lists and publications do not recognize it as distinct.[5]
Riccardin C is a phenolic cyclic bibenzyl secondary metabolite isolated from R. hemisphaerica,[6] as is marchantinquinone.[7]
