Six new infraspecific taxa in Eucalyptus (Myrtaceae) for Victoria

Abstract

The six new taxa described here are some of several recently discovered, unnamed eucalypts occurring in Victoria. Others will be treated in future papers. All six are markedly restricted and are described as subspecies within three existing species. Two subspecies occur in the Wimmera region; Eucalyptus viminalis Labill. subsp. siliceana Rule is from the Wail State Forest, and £ goniocalyx F. Muell. ex Miq. subsp. viridissima Rule is from Mt. Arapiles and in parts of the northern Grampians. Three subspecies occur near Bacchus Marsh; £ goniocalyx F. Muell. ex Miq. subsp. laxa Rule, is from the Brisbane Ranges to the south-west of Bacchus Marsh, £ goniocalyx F. Muell. ex Miq. subsp. falfax Rule in the Blackwood Range to the north-west of Bacchus Marsh, and £ baueriano Schauer subsp. thalassina Rule is from the Werribee River catchment area. Eucalyptus baueriana Schauer subsp. deddickensis Rule is from the Deddick River in East Gippsland.The affinities, ecology, distribution and conservation status of each taxon are discussed.

Eucalyptus wimmerensis revisited and notes on the morphologies and taxonomies of five Victorian mallee-boxes

“…Although £ silvestris appears to be related to £ microcarpa on the basis of leaf morphology, it is regarded as being different, not only in its inflorescence structure but in its smaller, sometimes mallee-like habit, its narrower juvenile leaves (1.5-3 cm wide compared with 3-6 cm wide) and its narrower, greener, more lustrous adult leaves (to 2 cm wide compared with to 3 cm wide). Nicolle (1997Nicolle ( ), (2006Nicolle ( ) (2013Nicolle ( ) and (2015 regarded £ silvestris as conspecific with £ odorata without addressing any of the differences between the two given in the original description by Rule (1994 and2012), particularly with regard to adult leaves and fruits.…”

“…However, Brooker (2000), in his revision of the genus, discarded the series and assigned the mallee-boxes to the Supraspecies Moluccanae within the Series Buxeales. Rule (2012) noted that Brooker's construct was an aggregation of morphologically diverse taxa and opted to define a narrower, informal complex of species which possess specific, shared features.This informal collective, here referred to as the Eucalyptus odorata Complex, is further used to accommodate the new taxa described below.…”

A box on the river: The phylogenetics and phylogeography of Eucalyptus baueriana (Eucalyptus sect. Adnataria ser. Heterophloiae)

“…In 2011, Rule [ 19 ] described two new subspecies of E . baueriana , both restricted to isolated populations in Victoria.…”

“…Eucalyptus baueriana subsp. thalassina includes all populations in the Werribee River catchment west of Melbourne and was considered to be morphologically distinct based upon its “smaller habit, smaller buds with shorter pedicels and smaller fruits” [ 19 ]. Populations on the Deddick River in eastern Victoria were classified as E .…”

Five new endemic eucalypts for Victoria

“…Comparisons between E carolaniae and related species. Included in the key are references to various subspecies of E. goniocalyx, three of which were described byRule (2011).…”
