Four new obligate seeder taxa of Eucalyptus series Rufispermae (Myrtaceae) from the transitional rainfall zone of south-western Australia
NICOLLE, D.
Three new species are described, viz. E. vittata D.Nicolle, an obligate seeder previously confused with the respouter species E. sheathiana Maiden and also differing from the latter in the narrower adult leaves and smaller buds and fruits_; E. frenchiana _ D.Nicolle_,_ an obligate seeder from between Norseman and Hyden, previously confused with E. corrugata Luehm. but most closely related to E. pterocarpa C.A.Gardner ex P.J.Lang and differing from the latter in the smaller leaves, buds and fruits and the hemispherical opercula; and E. distuberosa D.Nicolle_,_ an obligate seeder previously confused with the respouter species E. pileata Blakely_._ Two subspecies are recognized in E. distuberosa, viz. subsp. distuberosa, of widespread but scattered distribution in the southern goldfields, and subsp. aerata D.Nicolle, restricted to Bronzite Ridge west of Norseman. A key to the obligate seeder taxa of E. ser_._ Rufispermae Maiden is provided.
