Muelleria 34:3-9 ROYAL Published online in advance of the print edition, 4 August 2015. BOTANIC GARDENS VICTORIA A new species of Podolepis (Asteraceae: Gnaphalieae) from New South Wales Jeffrey A. Jeanes Royal Botanic Gardens Victoria, Birdwood Avenue, Melbourne 3004, Victoria, Australia; e-mail: [email protected] Introduction Abstract The genus Podolepis Labill. is generally regarded as polyphyletic (e.g. Podolepis omissa Jeanes, a new species endemic to north-eastern New South Short et al. 1989; Anderberg 1991; Konishi et al. 2000; Jeanes 2015) and Wales and closely related to P. neglecta in need of revision.The results of molecular work by Konishi et al. (2000) G.LDavis, is described and illustrated. support the reinstatement of both Panaetia Cass, and Siemssenia Steetz Its distribution, habitat and ecology are at some level and the removal of Podolepis kendallii (F.Muell.) F.Muell. and discussed. Podolepis georgei Diels (the latter to Schoenia ayersii (F.Muell.) J.M.BIack; Key words; taxonomy, morphology, see Wilson 1992). Although a few species are not represented in the data diagnostic features, Asteraceae set used by Konishi et al. (2000), it is clear that Podolepis s. str. (the clade that includes the type species, P. rugata Labill.) includes those species in which the limbs of the ray florets greatly exceed the involucre, and the individual involucral bracts have the claw and lamina discreet (i.e. attached only at the apex of the claw). Also included in this clade are P. arachnoidea (Flook.) Druce and P. neglecta G.LDavis. Podolepis s. str, consists currently of 18 species (Jeanes 2015) confined to Australia and found in all States as well as the Northern Territory and the Australian Capital Territory. For a detailed taxonomic and nomenclatural history of Podolepis and for an evaluation of the characters used to distinguish taxa, see Davis (1957). It is dear from the work of Davis (1957) and subsequent taxonomic treatments (e.g. Flenderson 1969; Beadle 1980; Cooke 1986; Stanley 1986; Everett 1992; Jeanes 1999, 2015), that the morphology of the intermediate involucral bracts is of importance in the delineation of species in Podo/ep/s. This remains true in the present ® Royal Botanic Gardens Victoria 2015 ISSN: 0077-1813 (print) • ISSN: 2204-2032 (online) Jeanes study, but other characters such as indumentum, leaf long and 2-10(-18) mm wide, apex acuminate. morphology and capitulum size and shape often also Capitulescences simple or paniculiform. Peduncles 1-10 prove useful. Furthermore, some species are apparently cm long, with several scarious scale leaves below the habitat specific. involucre passing into the leafy stem. Capitula 1 -several, In a recent paper (Jeanes 2015) I redefined Podolepis s. hemispherical, mostly 10-20 mm diam., 10-12 mm str. using a combination of morphological and molecular long. Involucral bracts multiseriate, with slender linear data. While researching this paper the name Podolepis claws, unequal (outermost shortest, intermediate sp. Warrabah, J.R. Hosking 1862, NSW Herbarium (APNI longest); claw stiff, glandular, shiny, straw-coloured, 2014), came to my attention. After an initial consultation with an elongate central depressed green section on with my colleague J.R. Hosking and the subsequent the stereome, most prominent towards the apex; lamina examination ofherbarium specimens, it became obvious scarious; intermediate bracts 5-8 mm long, claw c. 1 mm that this was a discrete taxon previously confused wide at the narrowest point, lamina ovate to triangular, with P. neglecta (Fig. 1). Some herbarium specimens to c. 3 mm wide, extending to c. 4 mm beyond apex were already segregated as P. sp.

Until recently this species has Eucalyptus/CallltrisVent species. (Fig. 5) been overlooked and included in Podolepis neglecta, Conservation status: Reasonably common, itself a species overlooked for many years until its first widespread and represented in conservation reserves description in 1957. and thus neither endangered nor threatened. Flowering period: Most months of the year, but most flowering herbarium specimens were collected in summer and autumn. Flowering is probably rain dependent. Diagnostic notes: Podolepis omissa is readily distinguished from P. neglecta by its intermediate involucral bracts which are shorter and have laminas with acuminate rather than acute to obtuse apices. These distinctions were consistent and unambiguous in the many herbarium specimens examined during this study. The two species are apparently never sympatric and inhabit discrete biogeographical regions. The generally broader lower cauline leaves and slightly larger capitula of P. neglecta are also useful features for Figure 4. Intermediate involucral bracts x5 a.
