''Eucalyptus cyclostoma'' is part of the subgenus ''Symphyomyrtus'' section ''Dumaria'' in a sub-group of nine closely related species in the series ''Ovulares''. The other members of this series include the smooth barked '' E. cylindrocarpa'', '' E. exigua'' and '' E. oraria'', and the rough barked '' E. ovularis'', '' E. aequioperta'', '' E. brachycorys'', '' E. myriadena'' and '' E. baudiniana''.
Distribution
This eucalypt is found on limestone plains on the south western Goldfields-Esperance region of Western Australia growing in sandy loam or red sand soils. It has a limited range around Balladonia and Zanthus where it forms part of low woodland communities.See also
