Nuytsia 20: 309–318 (2010). Verticordia mitchelliana subsp. implexior A.S.George & M.D.Barrett and Verticordia setacea A.S.George are described and discussed. Verticordia setacea belongs with V. gracilis A.S.George in section Platandra, previously a monotypic section. Introduction The genus Verticordia DC. (Myrtaceae: tribe Chamelaucieae) is a charismatic group of shrubs found mainly in south-western Australia, with several species in adjacent arid regions and three in tropical Australia (George 1991; George & Pieroni 2002). Verticordia is currently defined solely on the possession of divided calyx lobes, but the limits between Verticordia and the related genera Homoranthus A.Cunn. ex Schauer, Chamelaucium Desf. and Darwinia Rudge are difficult to define conclusively, and other characteristics such as anther morphology suggest conflicting relationships (Bentham 1867; Craven & Jones 1991; George 1991). A recent analysis using a single chloroplast gene, with limited sampling of Verticordia taxa (Ma et al. 2002), suggests that Verticordia may be polyphyletic. -
Variation in Seed Production and Germination in 22 Rare and Threatened Western Australian Verticordia (Myrtaceae)
Journal of the Royal Society of Western Australia, 84:103-110, 2001 Variation in seed production and germination in 22 rare and threatened Western Australian Verticordia (Myrtaceae) A Cochrane1, K Brown2, S Cunneen3 & A Kelly4 1Threatened Flora Seed Centre, Department of Conservation and Land Management, Locked Bag 104, Bentley Delivery Centre, Perth WA 6983 2Environmental Weeds Action Network, 108 Adelaide Terrace, East Perth WA 6000 3CSIRO Centre for Mediterranean Agricultural Research, Floreat WA 6014 424 Carnarvon St, East Victoria Park WA 6100 email: [email protected] Manuscript received August 2000, accepted March 2001 Abstract This study investigates the reproductive potential of 22 rare and threatened Western Australian taxa in the genus Verticordia (Myrtaceae) over a 5-year period. Considerable inter- and intra-specific variation in both seed production and germinability was demonstrated for the majority of taxa. The seed to flower ratio, or “seed set”, ranged from 0% to 68% with an overall mean of 21% in 82 accessions representing seed from 48 populations of the 22 taxa. Percentage germination ranged from 7% to 100% with an average of 49% for 68 accessions. The precariously low annual reproductive capacity of some of the more restricted and critically endangered taxa threatens their survival and unexpected disturbance events may result in population decline or even localised extinction. Mitigation measures such as the reintroduction of plant material into new sites and the enhancement of existing populations through additional plantings may be warranted for many of Western Australia’s rare and threatened Verticordia. Keywords: Verticordia, seed production, germination Introduction prominently displayed feathery flowers are borne singly but appear as heads or spikes and are generally brightly Verticordia (family Myrtaceae, sub-family coloured, ranging from yellow to red to purple. -

Conservation Advice: Homoranthus Bebo L.M. Copel (Myrtaceae)
Homoranthus bebo L.M. Copel (Myrtaceae) Distribution: Endemic to NSW Current EPBC Act Status: Under consideration for listing as Critically Endangered Current NSW TSC Act Status: Not Listed Proposed change for alignment: List as Critically Endangered on EPBC Act Conservation Advice: Homoranthus bebo Summary of Conservation Assessment Homoranthus bebo was found to be eligible for listing as Critically Endangered under Criterion B1ab(iii, v) + 2ab(iii, v). The main reasons for this species being eligible are i) that it has a highly restricted geographic distribution with both an extent of occurrence (EOO), estimated by calculating the area within the smallest possible polygon containing all known records as per IUCN Guidelines (2016), and an area of occupancy (AOO), estimated using 2 x 2 km grids as per IUCN Guidelines (2016), of 4 km2; ii) the species is known from a single location in Dthinna Dthinnawan Nature Reserve in the far North of NSW; iii) there is a projected continuing decline inferred in area, extent and/or quality of habitat and number of mature individuals as the species appears extremely sensitive to fire and observations suggest very slow rates of recruitment and recolonization of burnt patches, hampering the species ability to recover following disturbance events. The size and extent of the population is such that the entire species could be lost during a single fire event of moderate severity if it is assumed that all adult plants are killed by fire and there is no seedling recovery post- fire (as has been observed in response to a recent fire). Description and Taxonomy Homoranthus bebo was first described by L. -

Notes on Myrtace (Continued)
MR. 0. DENTIIhM 05 M\PPRTILCEIE. 129 HOMORANTHUS,A. Cixnn., is a single species which has scarcely even the claims of Actinodium to be excluded from Darwinia, dif- fering from the latter genus only in the subulate calyx-lobes. Its retention may, however, be justified as facilitating the distinction between Darwinia and Perticordia. VERTICORDTA,DC., contains at present 37 species, showing considerable diversity in the structure of the anthers as well as in the ovule?, and connected together by the single character of the dissected or plumose calyx-lobesj but this character gives so peculiar an aspect that it is justly allowed to supersede all others, and the genus is universally acknowledged in its integrity. The only separation proposed was Lindley's CltrysorrhoC, in the original species of. which a very singular form of anther was observed to be connected with the bright-yellow flower. Subsequent researches, however, have shown in other species a gradual passage from these singular-shaped anthers to one of the two normal types of the genus, and that they do not correspond at all with the colour of the flower; and Chrysorrhol was very soon given up even as a section. The division of Verticordia into two artificial sections, by the same characters which mpply the more natural separa- tion of Darwinia from Chamcelaucium, has been already alluded to; and further details on the arrangement of the species are now superseded by the ' Flora Aushraliensis.' PILEANTHUS,Labill., is an old genus of two or three species, characterized, again, chiefly by the calyx, in which accessory lobes are produced from the sinus precisely resembling the primary ones, the whole ten being broad, petal-like, and spreading, giving the calyx a shuttlecock-aspect, accompanied alao by a conversion of the staminodia into stamens, thus doubling the number of perfect stamens as well as of calyx-lobes. -
Darwinia Hortiorum (Myrtaceae: Chamelaucieae), a New Species from the Darling Range, Western Australia
K.R.Nuytsia Thiele, 20: 277–281 Darwinia (2010) hortiorum (Myrtaceae: Chamelaucieae), a new species 277 Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia Kevin R. Thiele Western Australian Herbarium, Department of Environment and Conservation, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Email: [email protected] Abstract Thiele, K.R. Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia. Nuytsia 20: 277–281 (2010). The distinctive, new, rare species Darwinia hortiorum is described, illustrated and discussed. Uniquely in the genus it has strongly curved- zygomorphic flowers with the sigmoid styles arranged so that they group towards the centre of the head-like inflorescences. Introduction Darwinia Rudge comprises c. 90 species, mostly from the south-west of Western Australia with c. 15 species in New South Wales, Victoria and South Australia. Phylogenetic analyses (M. Barrett, unpublished) have shown that the genus is polyphyletic, with distinct eastern and western Australian clades. Along with the related genera Actinodium Schauer, Chamelaucium Desf., Homoranthus A.Cunn. ex Schauer and Pileanthus Labill., the Darwinia clades are nested in a paraphyletic Verticordia DC. Many undescribed species of Darwinia are known in Western Australia, and these are being progressively described (Rye 1983; Marchant & Keighery 1980; Marchant 1984; Keighery & Marchant 2002; Keighery 2009). A significant number of taxa in the genus are narrowly endemic or rare and are of high conservation significance. Although taxonomic reassignment of the Western Australian species of Darwinia may be required in the future, resolving the status of these undescribed species and describing them under their current genus helps provide information for conservation assessments and survey. -

Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud-bearing structures, are used inconsistently in the literature. Key words: bud bank, fire-prone ecosystems, Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground lignotuber, resprouting, rhizome, xylopodium. provides fitness benefits in fire-prone ecosystems. Thus, in these ecosystems, there is a remarkable diversity of bud-bearing structures. There are at least six locations where belowground buds are stored: roots, root crown, rhizomes, woody burls, fleshy
