New taxa, combinations and typifications in Verticordui (Myrtaceae: Chamelaucieae). Nuytsia 7(3): 231-394 (1991). The history of Verticordia DC. is summarised. The morphology is reviewed, in particular the anthers, many of which are illustrated by scanning electron micrographs. The cytological findings of Rye (1979) are reviewed. The generic status is assessed and maintained in its broad sense. A new infrageneric classification of the genus Verticordia is provided, including 1 new subgenus and 18 new sections, while 3 names are given new status at sectional level. 41 new species, 12 new subspecies and 22 new varieties are described; 3 previously published names are reinstated as accepted species. 7 names previously published at specific rank are reduced to varieties and 1 to subspecies. Darwinia verticordina F. Muell. is transferred to Verticordia. The genus now contains 3 subgcnera, 24 sections, 97 species and 42 infraspecific taxa. Key s to all taxa are provided. Lectotypes and neotypes are chosoi for a number of earlier names. Distribution maps are provided for all new species and infraspecific taxa.

(Myrtaceae: Chamelaucieae). It covers new taxa and combinatifflis, lectotypifications and neotypifications and presents an infrageneric classification. Keys to all infrageneric taxa and species are provided; infraspecific taxa are keyed out under the relevant species. The papier will be followed by a book on the genus by Elizabeth A. George (formerly E. A. Bemdt), in which all taxa will be illustrated in colour, and later a treatment by the author in the “Flora of Australia”. Both these publications will contain descriptions of all taxa. A Verticordia Reference Collection has also been compiled by Elizabeth George, with the assistance of many collectors and observers. This contains representative spiecimens of almost all spiecies and infraspiecific taxa, and is available for consultation in the Reference Collection of the Western Australian Herbarium. As is the case with many genera in the Australian flora, Verticordia has not been revised since the treatment by George Bcntham (1867). Several taxa have been described since then, but it has been obvious to workers in Western Australia that some names have been wrongly applied and that many new taxa awaited description. Compilation of the Verticordia Reference Collection has accentuated the need both for a review and its early publication. Research on the cultivation of these colourful plants is also increasing rapidly. History The first spiecimens of plants later to be named Verticordia were collected at King George Sound in October 1791 by Archibald Menzies, on the Vancouver expiedidon. These spiecimens, of V. plumosa, are now at the Natural History Museum, London. Most subsequent collectors gathered specimens of Verticordia, but it was not until 1826 that the first two spiecies were named by Rene Louiche Desfontaines, and then in the genus Chamelaucium which he had described in 1819. Two years later, Augustin Pyramus de Candolle recognised these as a distinct genus to which he gave the name Verticordia. Although he did not explain the etymology, it has generally been taken as a reference to the ancient goddess Venus as the ‘turner of hearts’ (e.g. Schauer 1840). Discovery of new species became rapid after the Swan River colony was founded in 1829. Many spiecies were described by Europiean botanists (espiecially John Lindley, Stephan Endlicher, Johann Schauer, Nicolas Turezaninow and Carl Meissner) from collections sent from the colony. Lindley published a new generic name, Chrysorhoe, for one spiecies but it was not maintained by other workers. One species described during this period, V. carinata Turez., was known only from the typie (Figure 15) until its rediscovery in March 1990. In 1859 the first spiecies to be described in AusU'alia were published by Ferdinand Mueller (V. wilhelmi F. Muell., published in 1855, is now placed in Homoranthus). By the time Bentham (1867) treated the genus in “Flora Australiensis”, 37 spiecies were known. Four new spxjcies were described in that work, one of which, V. harveyi (Figure 23), has only recently been rediscovered. Between then and the present papier, however, research has been piecemeal. Later in the 19th Century, Mueller described four more spiecies. Spiencer Moore described one in 1898, and Ludwig A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 233 Diels and Ernst Pritzel several in 1904. Subsequently, only six further species have been described, two by Charles Gardner in 1934 and 1943, one by Gardner and Alex George in 1963, one by George in 1966, and two tropical species by Norman Byrnes in 1977. Green (1985) listed 53 species for Western Australia, all except two of which are here maintained at that rank. To these may be added V. decussata Byrnes from the Northern Territory. In the present paper, 97 species are recognised, together with 42 infraspecific taxa. The large increase reflects factors common to a number of Western Australian genera: superficial resemblance of many species; the existence of localised taxa, many discovered within the past 30 years as accessibility improved; and lack of resources to review the genus earlier. Methods This review is based on a study of the gross morphology of herbarium and, in many taxa, fresh material, as well as specimens preserved in formalin-acetic-alcohol. Measurements were taken where possible from fresh, preserved or detergent-softened specimens. Most taxa have been studied in the field to record habit and habitat data, as well as flower colour and perfume. The last was a subjective assessment made at the time of collection - no nocturnal checks were made. Because androecial characters are useful in distinguishing many taxa but the anthers are of small size, many were examined and photographed by means of a scanning electron microscope. Material housed at 20 herbaria was examined. Types of all except two previously named taxa were located; for those two the types are assumed lost and neotypes are nominated below. Photographs were taken of most type sheets and will be lodged in the Western Australian Herbarium (PERTH). Diagnoses are provided for all infrageneric taxa together with a list of included species. In the treatment of species, only new taxa, new combinations and taxa needing lectotypification are covered. For economy, no treatment is given of other previously published taxa. The key to species, however, includes all sf)ecies, while infraspecific taxa are keyed out under the species. For ease of reference species are treated alphabetically. The synopsis of infrageneric classification (pp 282-283) provides a systematic sequence. Maps are provided showing the distribution of all new taxa. Localities were plotted by latitude and longitude. These are taken from all herbarium collections seen, including those in the Verticordia Reference Collection at PERTH. Vague and general localities (e.g. Swan River colony) have not been mapped. Specific details of localities of type collections and rare taxa have been omitted, in order to afford these populations some protection. The conservation status of all species and infraspecific taxa has been assessed and, where appropriate, coded according to the criteria of Leigh et al. (1981). The assessment is based on the number of collections, localities and to a less extent estimates of population size. The last factor is approximate, no accurate counts having been made. Full surveys will be carried out by the Western Australian Department of Conservation and Land Management. 234 Nuylsia Vol. 7, No. 3 (1991) Two infraspecific ranks are recognised here. Subspecies is used for those taxa that are - 1) morphologically distinct but not sufficiently so to be given specific rank, and - 2) geographically disjunct from the other subspecies. Variety is used where the morphological distinction is less clear- cut (there are often intermediates) and the distributions overlap. Latin diagnoses and descriptions were prepared using Steam (1966) as the principal reference. Morphology Habit. Most species are shmbs less than 2 m tall. The tropical species V. cunninghamii and V. verticillata may grow to small trees up to 7 m tall. A few south-western species sometimes exceed 2 m, namely V. cooloomia, V. grandis and V. lepidophylla. The shmbby species have a wide range of form. The most common is a bushy shmb, openly to densely branched, sometimes rounded, sometimes corymb-like, sometimes irregular. The corymb-like habit may be slender, e.g. V. nitens, V. cooloomia, or broad and robust, e.g. V. eriocephala. Several irregular forms have crowded foliage, resulting in an arm-like growth, e.g. V. crebra, V. longistylis. Some species are widely spreading rather than erect, e.g. V. huegelii, V. pulchella, V. penicillaris, V. oculata', the extreme is V. oxylepis which has a main stem usually less than 5 cm tall and a single layer of horizontal branches. Most species have a single basal stem and are fire-sensitive, being killed by fire. Regeneration is from seed. Six species consistently develop a small lignotuber which sprouts after fire; these are V. brevifolia, V. coronata, V. grandis, V. oculata, V. ovalifolia and V. pennigera. In a further seven species a small lignotuber occurs in some variants; these are V. chrysanthella, V. insignis, V. densiflora, V. habrantha, V. huegelii, V. oxylepis and V. plumosa. The three tropical species V. cunninghamii, V. decussata, V. verticillata - sprout from both the larger stems and the base after fire. The lignotuber has evolved in relatively few taxa of Verticordia compared with some other woody genera in the Australian flora, e.g. Banksia, Melaleuca. It is therefore of minor taxonomic significance in the genus. Fire-sensitive forms usually grow rapidly from seed and are often at their most floriferous stage within five years. Indumentum. In most species the vegetative parts are glabrous. A few have hispid stems, e.g. V. staminosa and V. endlicheriana, while several species of sect. Sigalantha, sect. Penicillaris and sect. Verticordella have ciliate or erose leaf margins. Many species have a pubescent, villous or silky hypanthium, and in some the petals, sepals, androecium and style may be variously hairy. The hairs are always simple except those of the style, which may be branched. The style hairs are usually arranged in a beard on which the pollen is deposited and presented at anthesis. Indumentum terminology follows that of Hewson (1988). Leaves. The leaves are simple and small, usually less than 2 cm long, and sessile or shortly petiolate. In some taxa there is a small pulvinus at the base which may persist on the branchlet after leaf fall. The lamina ranges from orbicular to narrowly linear and terete. The arrangement is decussate except in V. verticillata (in whorls of 3 or 4) and a few species in which they are scattered. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 235 Most species of subg. Chrysoma have two leaf forms. Those of the seedlings and the lower, non- flowering branches are linear and terete to semiterete or triquetrous, and those of the flowering branches are broader and concave, e.g. V. subulala, or shorter and thicker, e.g. V. grandiflora. V. cooloomia has three forms, those of the main stem being intermediate between the basal and the floral leaves (Figure 17). In species of sect. Chrysorhoe, subg. Verticordia and subg. Eperephes there is little difference (except sometimes in size) between the lower vegetative and upper floral leaves (e.g. Figures 21 , 23, 25). A few species can be recognised from the gross leaf form and arrangement, e.g. V. serrata, V. crebra, V. oculata, but usually floral characters are needed for determination. Inflorescence. Despite the impression of corymbs, racemes and spikes, all species of Verticordia have solitary, pedunculate axillary flowers. In the terminology of Briggs & Johnson (1979), Verticordia has a uniflorescence consisting of a pedunculate monad with 2 prophylls but lacking an anthopodium. Great variation in the length of the peduncle and in the length of the flower-bearing part of the branchlet gives rise to the appearance of large inflorescences. In those species that are corymb-like, the floral intemodes are short, the lowest flowers have long peduncles and those above are progressively shorter (Figure 17). The branchlets may also be similarly arranged, giving the whole plant a corymb-like appearance with all flowers of each season at the same level, e.g. V. nitens, V. eriocephala, V. roei and V. endlicheriana (especially var. compacta). In others the branching may be less regular, giving rise to scattered corymb-like groups, e.g. V. plumosa, V. vicinella. The peduncles may also be of more even length and the intemodes short, in which case the flower groups are rounded, e.g. V. brachypoda. Where the flowers have peduncles of even length the groups are raceme-like or spike-like depending on peduncle length (e.g. Figure 25). This is the case in much of subg. Eperephes and in V. mitchelliana, V. humilis and V. staminosa. The flowers may be erect, as in most corymb- like forms, turned sideways, as in most raceme- and spike-like forms, and sometimes spreading (F. staminosa) or pendulous (F. mitchelliana, V. humilis). In all species the prophylls are opposite and sessile, immediately below the hypanthium. They may be deciduous before or at anthesis or persistent. In several species they are united, e.g. F. grandiflora, V. nobilis, V. rutilastra, F. chrysantha. They are similar to the cheiridium as defined in Calytrix by Craven (1987) but for convenience are termed bracteoles in the treatment below. Flowers. The Verticordia flower appears inuicate, but much of the intricacy derives from having the sepals deeply divided in various ways. The petals are usually lobed, fimbriate or dentate, there are ten fertile stamens (five in F. picta and F. rennieana) alternating with ten staminodes, a simple but often hairy style, and the hypanthium is often hairy and/or sculptured and, in subg. Eperephes, bearing appendages. In all parts there is a large number of characters and states useful for distinguishing taxa. 236 Nuytsia Vol. 7, No. 3 (1991) Hypanthium. Following Johnson & Briggs (1984), this term is used in preference to perigynium and the less precise floral tube. The hypanthium is variously turbinate or hemispherical and is often 5- or 10-ribbed or -angled. It is sometimes constricted at the apex (e.g. V. grandiflora) or below (V. eriocephala, V. brownii). The surface may be smooth, rugose or honeycombed. In subg. Eperephes the hypanthium bears five reflexed appendages around its upper margin, alternate with the sepals (Figures 9G & D, KKH). They are green and usually are closely appressed to the hypanthium. Although termed herbaceous appendages by Bentham and later workers, they are succulent or firm in texture and are here referred to simply as reflexed appendages. The function of these appendages is unknown. Their size and form are useful in assisting to distinguish some taxa, especially in sect. Verticordella. Sepals. The sepals (in all except one species, V. verticordina) are divided into a number of lobes that are themselves plumose, fimbriate, erose or divaricately divided. In many species they also have recurved or reflexed basal auricles or cilia (Figures 9G, lOE), and in most of sect. Pennuligera there are reflexed basal lobes. There are five of these reflexed lobes, but one sepal has two, three each have one, and the fifth has none. These lobes are usually clawed and have a lamina that is peltate, scale- like and ciliate in some species, deeply fimbriate in others (and the divisions may be upturned at the base of the hypanthium). Verticordia verticordina, previously placed in the genus Darwinia, has undivided erose to shortly lacerate sepals but in most morphological features is similar to the species of sect. Infuscata. In the species treatments, the length of the sepal is measured from the base of the lamina to the apex of the longest fringe or lobe segment. In counting lobes only the well-defined segments are taken into account, not the small lateral cilia present in many species. Petals. These may be free or variously united with the androecium. The lamina may be digitately divided, fimbriate, dentate or erose, or rarely entire (F. picta, V. interioris, V. habrantha, V. Integra). In sect. Pennuligera and in V. rennieana each petal has two basal auricles. The orientation of the petals varies between species. They may be spread horizontally or erect, and in many species they spread widely at anthesis but later close over the centre of the flower. This opening and closing occurs overnight in some species, e.g. V. mitchelliana and V. capillaris, but in others occurs over several days, e.g. V. endlicheriana. The petals are measured from the base to the apex of the longest teeth, lobes or segments. Androecium. All species have 10 stamens and 10 staminodes, except V. picta and V. rennieana which have 5 fertile stamens and 15 staminodes. As in the other floral parts there are many characters here useful for distinguishing taxa - form, size, orientation of filaments, anthers and staminodes. The stamens and staminodes may be free or variously united (into prominently tubular form in V. staminosa and V. monadelphd). A.S. George, Verticordia (Myrtaceae: Chamelaucicae) 237 Figure 1.

They are usually glabrous, rarely hairy. Usually the staminodes are shorter. They are terete, compressed or flat, occasionally somewhat channelled, and glabrous, ciliate or glandular- warty. In Verticordia the anthers extrude the pollen at anthesis. This is effected by a contraction of the locules, squeezing the pollen through the pores or slits. A slightly gummy substance (pollenkitt. Knoll 1930; Knox 1984) is also produced, holding the pollen grains together in a loose mass. According to species (and usually the absence or presence of a style beard) the pollen then either remains on the anther or is collected by the style, but in each case is presented to the pollinator. The pollenkitt of Verticordia is not highly coloured. It may be involved in one or more functions, e.g. adhesion to the pollinator or stigma, or incompatibility of pollen and stigma (Echlin 197 1 ). A detailed study should be made of anther dehiscence, the formation of pollenkitt and pollen presentation. There are no recorded pollinators for Verticordia but Holm (1988) has published many preliminary observations on floral development and possible pollinators. A wide range of insects has been observed on Verticordia, including flies, wasps, bees, bugs and beetles (personal observations, T. Houston, A. Baines & M.E. Trudgen, pers. comm.). Here is a fascinating subject awaiting investigation. Because the anthers proved to have features usually diagnostic for species but are very small, a study was made using a scanning electron microscope. The material was mostly fixed in formalin- acetic-alcohol, then critical-point dried and gold coated. A selection of species from all sections of the genus except sect. Elachoschista was studied. In subg. Chrysoma, the anther is swollen adaxially, while the connective is broad and produced apically into a usually prominent appendage (Figures 1 , 2, 3 A & B). There are two pores towards the apex of the locules. Between them at the base of the appendage is a small protuberance. Its function is unclear, but it appears to rupture as the pollen is extruded and may be the point through which the pollenkitt that loosely binds the pollen grains is extruded. This substance appears to form within the connective, which is smooth and rounded before anthesis but depressed afterwards. Likewise the anther locules are smooth before anthesis but after extrusion of the pollen are shrunken with a rather ruminate pattern (Figures 1 G & H, 2 B & C, 3 A & B). Initially the pollen remains loosely piled on top of the anther (Figure 1 C), the appendage in a number of species probably acting as a collector until the pollen is removed. The size and form of the appendage varies greatly. A concave, entire or emarginate form is typical (Figure 1). In a few species, e.g. V. citrella, V. subulata, it is greatly reduced. In sect. Sigalantha it is large and infolded (Figure 2 A & B), while in sect. Unguiculata it is extended as two long horns (Figure 2 C). In sect. Chrysorhoe it is expanded to partly cover the apex of the anther, but the apex of the appendage is contracted and infolded like a small proboscis (Figure 2 F & G). The extreme expansion is in sect. Cooloomia, where the appendage forms two wings adnate to the anther to its base and curved across the front so as to almost enclose it within coarsely fimbriate margins (Figure 2 D &E). In some species of subg. Chrysoma the stamens remain in the same position from anthesis, but in others they spread widely at first and later curve over the centre of the flower. 248 Nuytsia Vol. 7, No. 3 (1991) In subg. Verticordia there is considerable variety of form and orientation of the anthers (Figures 3 C to 6 F). The anther is basically globular and basally attached. Usually it is turned adaxially, with the pores on the inner or upper face. The connective is not produced into an appendage or at most forms a small swelling, e.g. sect. Corymbiformis, sect. Intricata. In some species the anther is vertically compressed, e.g. V. gracilis, V. eriocephala. In sect. Intricata the anther is erect on the filament, the pores are adaxial and shortly slit-like before anthesis, with a nose-like swelling of the connective between them (Figure 6 A to C). Extrusion of the pollen in subg. Verticordia is through two pores, but in several species (e.g. in sect. Corymbiformis (Figure 4 D to F) and sect. Micrantha (Figure 3 I)) the pores appear to coalesce or almost so. The pores are sometimes elongated before opening, showing a tendency towards the slits of subg. Eperephes. Shrinkage of the anther occurs in this subgenus also, but not as markedly as in subg. Chrysoma. The surface is then finely rugose or reticulate and the small appendage, where present, also rugose. As in subg. Chrysoma, the stamens in some species of subg. Verticordia are erect or spreading at anthesis and then quickly curved over the centre of the flower. In other species they remain in the erect or spreading position. Subg. Eperephes has far more uniform anthers than the other subgenera (Figures 6 G to 7). The anther is expanded adaxially and opens by two slits along almost its full length. The connective is usually swollen dorsally but not produced into an appendage. There is usually a prominent groove between the locules. In many species the filament is recurved at the apex so that the anther faces upwards or even outwards. In sect. Integripetala the locules are turned downwards such that the slits are almost vertical on the adaxial face (Figure 6 G to I). The filament apex is greatly enlarged. Sect. Tropica (Figure 6 J to L) is perhaps a link between subg. Eperephes and subg. Verticordia, especially sect. Intricata. The connective apex is nose-like in both sections, and the slit-like pores in sect. Intricata are tending towards the long slits of sect. Tropica. After anthesis, however, the openings in sect. Intricata appear as pores, not slits. Style. Although the style is simple, it shows a variety of form. In most species of subg. Chrysoma and subg. Verticordia it is straight and central, included or exserted. Some species have a gently curved style or a geniculate apex. In most species of subg. Eperephes the style is curved in the upper part and in some species it is excentrically inserted on the hypanthium. All species of subg. Chrysoma have a glabrous style, as do some of subg. Verticordia. Most species of subg. Verticordia have aboard either just below the stigma or extending well down the style (Figures 8, 9). The hairs are simple (Figure 8 A to E) though sometimes with swollen apices, except in V. pritzelii and V. gracilis (Figure 8 G & H) which have shortly forked hairs. All species of subg. Eperephes have a beard usually just below the apex, usually of forked hairs (Figure 9). In V . jamiesonii the beard is in the lower half, while in sect. Tropica it forms a narrow ring immediately A.S. George, Verticordia (Myitaceae: Chamclaucieae) 249 below the stigma. The hairs of the style appear to serve as a pollen collector and presenter, receiving pollen extruded by the anthers. The stigma is usually small, but is capitate in several species, notably V. huegelii and V. multiflora. It is formed of prominently convex cells (Figures 8 A, C & H, 9 B & F). In subg. Verticordia and subg. Chrysoma, the style when exserted shows remarkable elongation. Before anthesis it is very short, not exceeding the androecium. When the flower opens it elongates rapidily and reaches its full length within a few hours. This has been observed, for example, in V. mitchelliana and V. capillaris. In these species the flower opens in the evening, with the petals spreading widely and the style short. By early the next morning, the style has elongated and the petals have closed over the centre of the flower. The style in subg. Eperephes is fully elongated or almost so by anthesis. In the bud it is once folded on itself and simply unfolds as the flower opens. There is one exception, V. grandis. In this species the style is tightly rolled in the bud, and uncoils circinnately at anthesis. Ovary. The ovary is unilocular. It may occupy the whole hypanthium or be located towards either the base or the apex. There are 1-13 ovules. In subg. Chrysoma there are 1 or 2 ovules laterally attached at the base of the ovary. In subg. Verticordia there are usually 1-3 ovules but occasionally as many as 5, also laterally attached at the base. Subg. Eperephes has 6-13 ovules on a basal peltate placenta. Eruit. The Verticordia fruit is dry and nut-like, enclosed within the faded perianth. It usually contains a single seed, occasionally 2. Externally a fruit is difficult to distinguish from a faded flower containing no seed. The present review has included no study of fruit. Flower colour and scent. For most taxa, colour is relatively consistent and is a useful diagnostic character, though in some sections such as Chrysoma and Verticordella the differences are subtle. Most species have brightly coloured sepals, petals, androecium and style. The principal colours are yellow, pink, red, orange, cream and white. The brightly-coloured taxa have various forms of sweet scent or none. A few taxa have dull flowers, notably V. oxylepis, V. longistylis and V.fastigiata; these have a pungent, unpleasant scent and may be pollinated by small marsupials. While in some taxa the colour simply fades as the flowers age, in others there is a marked change. Many taxa of sect. Chrysoma, sect. Jugata, sect. Unguiculata, and sect. Pilocosta have yellow flowers that turn deep red; some forms of V. picta and V. chrysostachys also turn deep red. V. serrata changes from golden to grey. These changes apparently occur after removal of pollen and loss of stigma receptivity, whether or not pollination has occurred, and may well be a device to reduce attraction to potential pollinators which will concentrate on still-fresh flowers (Lamont 1985). Phenology. Most south-western taxa flower in spring and summer. A few taxa begin to flower in late August and September but the greatest number is in flower from October to December. Quite a few continue well into summer while some taxa flower only in summer and autumn. Verticordia pityrhops and V. lehmannii continue into winter, at which season V. staminosa is the only species in full flower. The north-western and tropical species flower from July to October. 250 Nuytsia Vol. 7, No. 3 (1991) Figure 1 1. Distribution of Verticordia. Figure 12. Number of species of Verticordia per l°x l°grid in southern Western Australia. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 251 Geographical distribution The geographical distribution of Verticordia is shown in Figure 11. The genus occurs predominantly in the South West Botanical Province of Western Australia, where there are 90 species, several of which extend into the Eremaean Province; one species is confined to the southern Eremaean Province; three further species occur in north-western Australia and a further three occur in the Kimberley and Northern Territory. Figure 12 gives the number of species within the 1° x 1® grid of southern Western Australia. The figures are the number of species recorded. Infraspecific taxa were amalgamated as species for this exercise. Within the South West Botanical Province the figures demonstrate the preference of species for the regions of moderate rainfall between the wetter south-western comer of the continent and the transition to the Eremaean Province. The highest concentration is in the grid centred on Eneabba in the upper south west, where 34 species have been recorded; nineteen species have been recorded within 20 km of Eneabba. Across the heathlands generally there is a relatively even distribution with 16-24 species per grid, but there is some increase in the area south and south-east of Eneabba and in the area north and north-east of the Stirling Range. The increase is less marked than that of some genera in the south-western flora where there are two areas of high species richness, one to the north of Perth and one to the south-east, e.g. Dryandra (Griffin 1985) . The distribution of some infrageneric taxa may be highlighted. Subgenera Chrysoma and Verticordia are entirely south-western . Within this region, sect. Chrysoma, sect. Verticordia and sect. Corymbiformis are widespread, while other sections are restricted to varying degrees, e.g. sect. Chrysorhoe occurs near the lower west coast between B unbury and Eneabba; sect. Cooloomia occurs between the lower Murchison River and Shark Bay; sections Micrantha and Infuscata occur along the south coast between Cape Riche and Israelite Bay. A wider distribution is shown by subg. Eperephes which includes sect. Tropica in the Kimberley and the Northern Territory, sect. Jamiesoniana with one species in the upper Murchison-Gascoyne areas, sect. Integripetala which extends from the South West Province well into the Eremaean, and the very widespread sect. Verticordella. Sect. Pennuligera occurs only to the north of Perth and includes the two species in the north west. No doubt these distribution patterns will be reflected, at least to some extent, in those of the pollinators when known. Cytology The findings reported by Rye (1979) may be re-interpreted in light of the present review. The voucher collections from that study have been checked, necessitating some redeterminations (Table 1 ). In terms of generic and infrageneric classification, chromosome numbers, taken in conjunction with the morphology, do not support a generic split but do, in general, match the proposed infrageneric classification. All taxa of subg. Eperephes counted have n = 1 1 or 22, including V. picta which is here considered a link with subg. Verticordia. While the latter subgenus has four numbers (n = 6, 8, 9, 1 1) the species with 11, V. plumosa, is not closely related to any species of subg. Eperephes. Species of subg. 252 Nuytsia Vol. 7, No. 3 (1991) Verticordia here considered related to subg. Eperephes include V. pritzelii (n = 9) and V. humilis (2n = 16). Subg. Chrysoma has n = 6, 7, 8 and 16, yet taxa of this subgenus are more cohesive morphologically than are those of the other subgenera. From this it would appear that chromosome number in itself is not a strong character at subgeneric level. Rye’s vouchers cover 27 species of the 97 now recognised. In view of the large increase in the number of taxa, a further study of chromosome numbers is warranted. Table 1.

The plants are intermediate in morphology between the probable parents which, in most cases, were recorded at the same locality.

V. densiflora x V. eriocephala - SE of Dowerin, 7 Dec. 1983, M. Smith 113 (PERTH), a single plant; several other collections from Mt Lesueur to Nyabing. 2. V. nobilis x V. laciniata, e.g. Tathra National Park, 17 Oct. 1984, A.S. George 16351 &E. A £erndt (PERTH); also near Brand Highway/Coorow-Green Head Road junction. 3.

K rod subsp. roei xK. fnc/usa - South Bumgup Road, SW of Newdegate, 11 Oct. 19S1, E.Berndt 32 (PERTH), a single plant in a population of V. inclusa, with V. roei in vicinity. Further research While the present work resolves many taxonomic issues in Verticordia, much work remains to be done. Many taxa recognised here are clearly distinct (e.g. subg. Chrysoma, sect. Chrysorhoe, V. cooloomia). Others are somewhat heterogeneous (e.g. subg. Eperephes and sect. Intricata). A number of collections are still unplaced, in most cases due to inadequate material. Some of these are cited below, under the taxonomically nearest species. In particular, several species and species-groups should be studied further in order to clarify taxa and relationships. Particular attention should be given to V. plumosa, V. densiflora, V. acerosa, the chrysantha group, V. monadelpha, sect. Verticordella and the chrysostachys-muelleriana group. Aspects worthy of special study include cytology, pollination, flower ontogeny and seed development. Verticordia Verticordia DC., Prodr. 3: 208 (1828). -Diplachne sect. Verticordia (DC.) Kuntze, Lex.

Shrubs or in 2 species small trees, usually fire-sensitive, sometimes with a small lignotuber. Leaves opposite, rarely whorled or scattered, exstipulate, the floral leaves often somewhat different from the vegetative ones. Inflorescence an axillary pedunculate monad with a pair of free or united prophylls (bracteoles), usually in crowded upper axils and forming corymb-, raceme- or spike-like arrangements. Prophylls scarious, deciduous or persistent. Hypanthium present, turbinate or hemispherical, occasionally vertically compressed, sometimes constricted at apex or near middle, in subg. Eperephes usually with 5 green reflexed appendages at the apex. Sepals 5, imbricate, deeply divided into 5-15 plumose, fimbriate or erose lobes, rarely scarcely divided and lacerate to erose, with or without basal fimbriate auricles and in subg. Eperephes also with 5 reflexed lobes (3 sepals each with 1, 1 with 2 and 1 with 0) bearing a ciliate, fimbriate or comose lamina. Petals 5, imbricate, free or united with androecium, concave, fimbriate to erose, rarely entire, often pubescent to scabrid. Androecium of 10 stamens alternating with 10 staminodes, in 2 species of 5 stamens and 15 staminodes, free or variously united; filaments terete to compressed, of equal length or alternately A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 255 long and short; anthers 2-locular, not versatile, saccate or globular and opening by pores or short slits, or oblong and opening by slits; connective often produced above anther; staminodes terete, compressed or flat, sometimes lobed or divided, often glandular-waried, hairy or fimbriate. Style central, occasionally excentric, included or exserted, straight, curved or geniculate, glabrous or bearded with branched or simple hairs; stigma small, occasionally capitate. Ovary unilocular; ovules 1-13, basally attached either laterally or on a peltate placenta. Fruit dry and nut-like, enclosed within the persistent faded flower, 1- or 2-seeded. The traditional circumscription of the genus Verticordia is maintained here, except that V. wilhelmii is retained in Homoranthus to which it was transferred by Cheel in 1922. Verticordia is characterised especially by the sepals being usually divided into fimbriate or plumose segments, petals usually of similar size to the sepals and usually fimbriate or digitately lobed, and 10 stamens alternating with 10 staminodes, with basifixed or dorsifixed bilocular anthers. The closest generic relatives of Verticordia are Darwinia, Chamelaucium and Homoranthus. In these genera the sepals are small with an opaque lamina and scarious margins that are trifid, ciliate or entire. The petals are of more succulent texture than are those of Verticordia and are usually entire. InDarwinia and Chamelaucium the hypanthium is usually narrowly turbinate to almost cylindrical. All species of Darwinia and some Homoranthus have inflorescences of several flowers, in Darwinia usually with an involucre. It has been suggested, e.g. Rye (1979), Briggs & Johnson (1979), Johnson & Briggs (1984), that Verticordia be divided into 2 genera, namely Verticordia sensu stricto and ‘Catocalypta’ , the latter being the taxon described below as subg. Eperephes. As explained below, the name Catocalypta has been wrongly applied in the sense of all authors from Bentham (1867) onwards. The genus is much more complex than is implied by this suggestion, however, and if it were to be divided it would be into more than 2 genera. The infrageneric classification given below indicates the complexity. Much more research is needed before any formal generic split should be made. A comprehensive cytological study including the many new species here described would be useful. As mentioned in the section Cytology (above), the counts so far made do not support a generic breakup. As explained below, there are links between the subgencra here proposed, and also between several sections.

George A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 269 Infrageneric classification A revised infrageneric classification is presented here. It is based on overall morphology, important characters being the leaves, hypanthium, sepals, petals, anthers, style and ovules. Two ranks are recognised - subgenus and section. Few infrageneric taxa have been described previously. Only Bentham (1867) provided a detailed system but used formal names for two sections leaving the subsidiary groups informal. Schauer ( 1 840) recognised three subgenera on the basis of calyx and anther characters. The name of one of his subgenera, Catocalypta, has been widely misapplied since Bentham. Meissner (1857) divided the genus into four sections based on characters of the calyx. Bentham’s treatment in "Flora Australiensis" recognised two sections using anther and ovule characters. Within each section he grouped species on characters of the calyx, supplemented in some cases by the petals, anther connective, floral arrangement and leaves. Baillon (1877) ignored previous classifications and simply divided the genus into two sections - Euverticordia with no appendages to the calyx, and Calymmatantha (as Calymmatanthus), with comose calyx appendages. For the latter taxon he referred to Schauer’s t. 4B (1840), where the only species figured with comose sepal appendages is V. insignis, the lectotype of sect. Catocalypta. The same species is thus the type of sect. Calymmatantha, making it a superfluous name. Gardner (1930-3 1) followed Bentham’s division into two sections, with the same sectional names as that author. The following synopsis of the infrageneric taxa is in systematic order, with a tabulated summary at the end. The system is based on an assessment of the morphology and begins with the least complex floral form as seen in sect Chrysoma, passing to the most complex in sect. Pennuligera. While the relationship between some taxa at each rank is clear, it is less evident in others. Sections Infuscata and Elachoschista are evidently related to each other but their relationship to other sections is uncertain. Further study should clarify the systematic arrangement in the genus. Verticordia subg. Chrysoma Schauer, Monogr. Myrtac. Xerocarp. 220 (1840). Lectotype (here chosen): V. acerosa Lindley Typification. Schauer included five species with his protologue, namely V. acerosa Lindley, V. serrata (Lindley)Schauer, V. nitens (Lindley) Endl., V. chrysantha Schauer and V. grandiflora Endl. The diagnosis favours no species over another. Schauer misinterpreted the style as included in V. acerosa, V. serrata, V. nitens and V. chrysantha, possibly through examining unopened flowers. V. acerosa is therefore chosen arbitrarily as the lectotype. Bracteoles notapiculate. Hypanthium without appendages, glabrous. Flowers yellow, sometimes ageing red, in one species orange. Anthers saccate, opening by two pores towards apex, with an apical appendage. Style glabrous. Ovules 1 or 2.

The prominent staminodes, exceeding the stamens, are also unusual in the genus. Etymology. Named from the Greek elachys (little, short) and schistos (divided, cleft), in reference to the almost entire sepals. Verticordia sect. Penicillaris A.S. George, sect. nov. Folia linearia-oblonga, semiteretia, marginibus ciliatis-erosis. Flores tuimis parvis, cremei vel luteoli. Bracteolae cuspidatae, caducae. Hypanthium hemisphericum, non costatum, ad basin comosum.

Sectional epithet from the Latin pilus (hair) and costa (rib), in reference to the ribs of the hypanthium. Verticordia sect. Catocalypta (Schauer) Meissner, in W.J. Hooker, J. Bot. Kew Card. Misc. 8: 19 (1856). - V. subg. Catocalypta Schauer, Monogr. Myrtac. Xerocarp. 213 (1840). Lectotype (here chosen): V. insignis Endl. V. sect. Calymmatantha Baillon, Hist. PI. 6: 368 (1877), as Calymmatanthus, nom. superfl. Type: V. insignis Endl. Leaves oblong to linear, triquetrous, entire. Flowers in rounded or corymb-like groups, white or pink. Bracteoles not cuspidate, caducous. Hypanthium turbinate, 10-ribbed. Sepals lobes deeply fimbriate, and with basal auricles reflexed against hypanthium and densely fimbriate upturned apices. Petals spreading, fimbriate or entire. Stamens and staminodes erect to inflexed; anthers ± globular to rounded-trapezoid, sometimes with a swelling between the pores; staminodes broad, fimbriate, sometimes linear and entire or 1-2-lobed. Style included to exserted, glabrous. A section of six species - V. habrantha, V. inclusa, V. insignis, V. lehmannii, V. pritzelii and V. roei. Schauer included four species with the protologue of subg. Catocalypta, namely V. huegelii, V. compta (now = V. insignis subsp. compta), V. insignis and V. roei. In the diagnosis, he emphasised the reflexed auricles of the sepals that have divided apices upturned and forming a dense tuft (‘involucnim’) about the hypanthium. In fact V. huegelii does not have this character but instead has a tuft of hairs at the base of the hypanthium and no auricles to the sepals. This species is here placed in sect. Pilocosta. Schauer illustrated V. insignis, again highlighting the sepal auricles both in a figure and in the caption. This species is here selected as lectotype. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 111 In addition to this feature, other diagnostic characters of the section are the triquetrous leaves, large fimbriate or entire petals, usually fimbriate staminodes and glabrous style. V. pritzelii is somewhat anomalous in the section in its longer leaves but appears closely related to V. lehmannii. The name Catocalypta was correctly used by Turczaninow (1847) and Meissner (1857), but has been widely misapplied since Bentham (1867) excluded from it all taxa included by Schauer. Bentham misunderstood the anther form in particular, using the name for species having ovoid or oblong anthers opening by slits. Authors who have followed Bentham include Mueller (1878), Engler & Prantl (1892), Diels & Pritzel (1904), Gardner (1930-31) and Rye (1979). Verticordia sect. Platandra A.S. George, sect. nov.

Style slightly excentric, shortly exserted, towards the apex curved and bearded with forked hairs. A monotypic section. The species resembles V. pritzelii but differs especially in the non- auriculate sepals, flattened anthers and style beard of forked hairs. In the last character it shows a link with subg. Eperephes. Etymology. Named from the Greek platy- (flattened) and -andros (male), in reference to the compressed anthers. Verticordia sect. Recondita A.S. George, sect. nov. Folia omnia linearia, triquetra. Flores dissiti, nutantes, rubri. Bracteolae non cuspidatae, ad anthesin persistentes, postea deciduae. Hypanthium turbinatum sed ad basin constrictum, pilosum.

Stamens incurved with recurved anthers; staminodes subulate. Style exserted, with a small beard. Ovule 1. A monotypic section. V. humilis appears related to such taxa as V. gracilis and V. pulchella but at a sectional level does not rest easily with either. Etymology. Named from the Latin reconditus (hidden, not easily seen), in reference to the small stature, pendulous sparse flowers and closed petals covering the androecium. Verticordia sect. Intricata A.S. George, sect. nov. Folia linearia, triquetra vel semiteretia. Flores turmis laxis vel corymbiformibus, rubri vel rosei. Bracteolae non cuspidatae, caducae.

It is characterised especially by the divaricately-divided sepals with similar reflexed auricles, the fimbriate petals and erect androecium with small erect anthers and subulate staminodes. Etymology. Named from the Latin intricatus (intricate), in reference to the sepals. Verticordia subg. Eperephes A.S. George, subg. nov. Bracteolae plerumque apiculatae. Hypanthium cum appendiculis 5 apicalibus reflexis crassis viridibus, in taxis aliquot breviter limbatum vel appendiculis nullis, glabrum. Flores rosei, rufi, cremei, lutei vel albidi.

Ovules 6-13, on a peltate basal placenta. A subgenus of six sections containing 41 species. The name sect. Caiocalypta Schauer has often been apphed to this taxon but that name is correcdy used for a section of subg. Verticordia (see above). The subgenus is distinguished from the remainder of the genus especially by the anthers with ± parallel slits and the higher number of ovules. The species included in sect. Integripetala and sect. Tropica show other characters similar to some species of subg. Verticordia, and a generic split is not appropriate. Etymology. The subgenus is named from the Greek eperephes (overhanging, beetling), in reference to the 5 reflexed appendages of the hypanthium of many species. Verticordia sect. Integripetala A.S. George, sect. nov. Folia linearia vel clavata, semiteretia, glabra. Flores turmis corymbiformibus in ramulis lateralibus, rosei vel cremei.

Lectotype (here chosen): V. grandis Drummond Diplachne sect. Schizanthera Kuntze, Lex. Gen. Phan. 177 (1903). Based on Verticordia sect. Catocalypta sensu G. Bentham (1867) non (Schauer) Meissner (1856). Typification. Meissner listed three species with his diagnosis of sect. Pennuligera, viz. V. chrysostachys Meissner, V. oculata Meissner and V. grandis Drummond. Since his brief diagnosis applies well to all three, the first-named species is selected as lectotype. The sectional name has been ignored by subsequent workers except Mueller (1859). 282 Nuytsia Vol. 7, No. 3 (1991) Usually large, openly branched shrubs. Leaves ovate, elliptic, obovate or orbicular, usually similar throughout. Floral groups spike-like or raceme-like. Bracteoles cuspidate, persistent. Hypanthium turbinate, 5-ribbed, glabrous, with 5 reflexed appendages. Sepals with plumose lobes and peltate auricles covering hypanthium. Petals ovate, oblong or orbicular, fimbriate or rarely entire, with basal fimbriate auricles, inserted on base of androecium. Stamens uniform, erect to incurved; anthers extrorse to horizontal; staminodes linear, subulate or occasionally clavate.

Swan R. vi (1839). Lectotype (here chosen): Swan River, Western Australia, 183-,7. Drummond s.n. (CGE; probable isolecto: K). Other syntype: Swan River, Western Australia, 183-,/. Mangles s.n. (CGE). Typification. The two collections on the type sheet at CGE represent the same taxon but that by Drummond is the more complete, bearing lower leaves (which were described by Lindley) as well as upper leaves and flowers. Mangles’ collection lacks lower leaves. Verticordia acerosa is characterised by the caducous bracteoles, turbinate ribbed hypanthium, openly-fringed sepal lobes, deeply lobed petals, alternately long and short stamens, anthers with a short obtuse appendage, and fringed or dentate flat staminodes with an obscure midrib at least in the lower half. The species has two varieties. Staminodes fimbriate; floral leaves lanceolate to ovate var. acerosa Staminodes dentate; floral leaves either lanceolate to elliptic or orbicular var. preissii (Schauer) A.S. George 284 Nuytsia Vol. 7, No. 3 (1991) Verticordia acerosa Lindley var. acerosa Floral leaves lanceolate to ovate. Staminodes fringed. Distribution and habitat. Occurs on and adjacent to the Darling Scarp between Red Hill and Armadale, Western Australia, with a record from Boyanup. Grows close to granitic outcrops and in gravel, in open woodland and heath, and, on the coastal plain, in low-lying heath. Flowering period. September-October. Conservation status. Not rare or endangered. Verticordia acerosa var. preissii (Schauer) A.S. George, comb, et stat. nov. - Verticordia preissii Schauer, in J.G.C. Lehmann, PI. Preiss. 1: 101 (1844). Holotype: below ‘Halfway-house’, Western Australia, September 18—, L. Preiss 175 (LD; iso: FI, G, K, KW, L, P, W). Floral leaves lanceolate to elliptic, or broadly elliptic to orbicular. Staminodes dentate. Distribution and habitat. Occurs mainly on the Darling Plateau east of Perth, extending N to Mogumber, E to Tammin, and S and SE to Arthur River and the Oldfield River, Western AustraUa; a few records on the eastern coastal plain near Perth. Grows in sandy gravel and on clay flats, in heath and low open woodland. Flowering period. September-October. Conservation status. Not rare or endangered. Verticordia acerosa var. preissii is variable. In its typical form it has lanceolate to narrowly elliptic floral leaves and stiff petal lobes, and is of similar size in floral parts to var. acerosa. This form occurs mainly on the Darling Plateau to the E and N of var. acerosa, with some populations within the distribution of var. acerosa, e.g. Cannington, 27 September 1900, A. Morrison s.n. (BM, PERTH). Further inland it usually has broadly elliptic to orbicular thick floral leaves, slightly smaller flowers, shorter stamens, shorter and broader staminodes, and more slender petal lobes. Collections with very broad staminodes include 99 mile peg [c. 158 km]. Great Eastern Highway, 5 September 1966, EM. Scrymgeour [Bennett] 663 (PERTH); Cunderdin, August 1903, W.V. Fitzgerald (PERTH); W of Woodanilling, 25 August 1970, H. Demarz 2539 (PERTH); and N.G. Marchant 71/581 (PERTH). The name V. preissii has been widely misapplied to V. endlicheriana Schauer and the species described below as V. chrysanthella. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 285 Verticordia albida A.S. George, sp. nov. Ad Verticordiam chrysostachydem Meissner affmis, a qua floribus albidis (raro roseis) in centre roseis, petalis brevioribus latioribus, staminibus parce glandulosis, et stylo minus curvato ad apicem undique piloso pilis ± sparsis, differt.

Lullfitz 1934 (hole: PERTH; iso: B). Related to V. chrysostachys from which it differs in the flowers while (rarely pink) with pink centre, petals shorter and broader, stamens sparsely glandular, and style less curved and with ± sparse hairs surrounding the upper style. Petals 4-5 mm long, 3-4 mm wide. Style 6-6.5 mm long with hairs 0.5-0.7 mm long. Distribution and habitat. Recorded from a small area SW of Three Springs, south-western Western Australia (Figure 32). Grows in grey to yellow sand over gravel, in shrubland. Flowering period. Late November-January. Conservation status. 2E. The few records are from road verges in a well-cleared area. Etymology. From the Latin albidus (whitish), in reference to the sepals and petals. This new species of the ‘chrysostachys' group oi Verticordia sect. Pennuligera is distinguished by the whitish flowers with pink centres, the almost orbicular petals and the curved upper part of the style with a surrounding beard of rather sparse hairs 0.6-0.7 mm long. Verticordia amphigia A.S. George, sp. nov. Ad Verticordiam chrysantham Endl. affmis, a qua foliis gracilioribus, bracteolis fimbriatis late naviculiformibus, floribus minoribus (sepala 2-2.5 mm longa et 5-7-lobata, petala 2.5 mm longa), antheris parvis (0.3 mm longa) et staminodiis anguste triangularibus 1.3-1.7 mm longis, differt. Typus: S ofCockleshellGully, Western Australia, 30“ 11' S, 1 15"07'E, IbOctober 1984, A.S. George 16318 & E.A. Berndt (holo: PERTH; iso: CANB, K). Related to V. chrysantha, differing in the more slender leaves, the broadly boat-shaped fimbriate bracteoles, the smaller flowers, small anthers and narrowly triangular staminodes. Sepals 2-2.5 mm long, 5-7-lobed. Petals 2.5 mm long. Anthers 0.3 mm long. Staminodes 1.3-1.7 mm long. Distribution and habitat. Recorded from several localities at and near Cockleshell Gully and near Eneabba, Western Australia (Figure 32). Grows in winter-damp sandy loam, clay and rocky loam in low shrubland. Flowering period. October-early November. 286 Nuytsia Vol. 7, No, 3 (1991) Conservation status. 2RC. Ail populations are in conservation reserves and one numbers several hundred plants. Eytmology. Named from the Greek amphigyos (pointed at both ends), in reference to the boat-shaped pair of bracteoles subtending each flower. In the dried state these sometimes resemble pixie ears. Verticordia argentea A.S. George, sp. nov. Inter species Verticordiae sect. Pennuligerae floribus pallide roseis fimbriis loborum sepalorum albo-argentiis et stylo ± recto, praecipue differt. Folia transverse ovata ad orbicularia, 4-7 mm longa, 3.5-8 mm lata. Pedunculi 1-1.5 mm longi. Sepala4-5 mm longa lobis 7-10. Petala 5-5.5 mm longa, 3- 4 mm lata, fimbriis acutis ad 2 mm longis. Stylus 4.5-5 mm longus pilis c. 0.3 mm longis. Typus: S of Eneabba, Western Australia, 29° 53' S, 1 15° 18' E, 24 January 1979,5. Barnsley 892 (holo: PERTH; iso; CBG). Distinguished within Verticordia sect. Pennuligera especially by the pale pink flowers with silver-white fringe to the sepals and by the ± straight style. Leaves transversely ovate to orbicular, 4- 7 mm long, 3.5-8 mm wide. Peduncles 1-1.5 mm long. Sepals 4-5 mm long with 7-10 lobes. Petals 5- 5.5 mm long, 3-4 mm wide, with acute fimbriae to 2 mm long. Style 4.5-5 mm long with hairs c. 0.3 mm long. Distribution and habitat. Restricted to an area S of Eneabba, Western Australia (Figure 33). Grows in grey and brown sand in shrubland, sometimes with open woodland of Eucalyptus todtiana. Elowering period. Mainly November-March. Conservation status: 2E. The populations are apparently small. Etymology. From the Latin argenteus (silvery) in reference to the prominent fringe of the sepal lobes. Verticordia argentea is closely related to V. muelleriana and is distinguished especially by the pale pink and silver flowers and the straight style with a beard of short hairs over the upper third. The staminodes are shorter than the stamens and have few oil glands. The species has a long flowering period, extending through summer to early autumn. In morphology it is quite uniform, but the pink colouration of the flowers varies somewhat in intensity, and cream flowers have been recorded {Griffin 825, PERTH). Verticordia attenuata A.S. George, sp. nov. Ab speciebus aliis Verticordiae sect. Verticordellae petalis multo angustatis ad apicem fimbriatis, et stylo crasso (ad medium 0.3-0.4 mm lato) praecipue differt. Typus: Ludlow, Western Australia, c. 33°37'S, 1 15°29'E, 8 January 1971,A.5. George 10617 (holo: PERTH; iso: CANB, K). A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 287 Differs from other species of Verticordia sect. Verticordella especially in the petals being markedly narrowed towards the few-fimbriate apex and in the thick style (0.3-0.4 mm wide near mid- point). Distribution and habitat. Occurs from Bunbury S to Ludlow and Ruabon, south-western Western Australia (Figure 32). Grows in winter-wet grey sand in eucalypt woodland and shrubland. Flowering period. December-April. Conservation status. 2E. Known from only a few roadside populations in a relatively well-cleared area. Etymology. Named from the Latin attenuatus (narrowed), in reference to the characteristically narrowed petals. The species is closely related to V. drummondii. The style appears strap-like when dried. Verticordia aurea A.S. George, sp. nov. Ad Verticordiam nitentem (Lindley) Endl. affinis, a qua floribus majoribus aureis (hypanthium 1.5-2 mm longum, sepala 3.5-4 mm longa, petala 4-4.5 mm longa), staminodiis latioribus (anguste ovatis) et florescentia praecociore (October-December praecox), differt. Typus: S of Eneabba, Western Australia, 29°54' S, 115° 16' E, 9 December 1974, A.S. George 12932 (holo: PERTH; iso: AD, CANB, K, MEL. NSW, PERTH). Closely related to V. nitens (Lindley) Endl. from which it differs in the larger golden flowers, broader staminodes and earlier flowering period. Hypanthium 1 .5-2 mm long. Sepals 3.5-4 mm long. Petals 4-4.5 mm long. Staminodes narrowly ovate. Distribution and habitat. Occurs from c.30kmStoc.l0kmN of Eneabba, Western Australia (Figure 34). Grows in deep sand in heath and banksia low open woodland. Flowering period. October-early December. Conservation status. 2RC. The species is locally common but some populations are threatened by clearing. Etymology. From the Latin aureus (golden), in reference to the colour of the flowers. Verticordia aurea is closely related to V. nitens but differs in the larger, golden flowers and the broader staminodes. Usually the leaves are thicker than those of V. nitens. The species flowers earlier, mostly October-November, in contrast to the December-January flowering period of V. nitens. 288 Nuytsia Vol. 7. No. 3 (1991) Verticordia auriculata A.S. George, sp. nov. Ab speciebus Verlicordiae sect. Verticordellae turmis florum parvis, floribus parvis, etauriculis prominentibus sepalorum praecipue differt. Frutex ad 50 cm altus, raro ad 70 cm, ramosissimus.

Verticordella especially in the small groups of small flowers and the prominent auricles of the sepals. A shrub to 50 cm tall, rarely to 70 cm, much- branched. Leaves appressed, 1 .5-2 mm long. Peduncles 1.5-2 mm long. Hypanthium 2-2.5 mm long, ribbed; appendages 1.5 mm long. Sepals 4 mm long, with prominent silvery auricles. Petals 5 mm long with fimbriae to 1.8 mm long. Style 5 mm long, sigmoid towards apex; beard hairs to 0.5 mm long. Distribution and habitat. Occurs in the north-eastern agricultural areas of south-western Western Australia, mainly from Perenjori to Koorda, but also recorded from the Pindar- Yalgoo area (Figure 33). Grows in gravelly loam, sandy loam over gravel and yellow sand, in shrubland. Flowering period. Late October-December. Conservation status. Not rare or endangered. Etymology. Named from the Latin auriculatus (auriculate, with ear-like lobes), in reference to the prominent fimbriate basal lobes of the sepals. The prominent auricles of the sepals are diagnostic for this member of the small-flowered group of sect. Verticordella. Verticordia bifimbriata A.S. George, sp. nov. Ab speciebus Verticordiae sect. Verticordellae fimbria petalorum ipsa fimbriata et appendiculis hypanthii incrassatis apice ± acuto libero praecipue differt. Folia anguste elliptica, 1 .5-4 mm longa. Pedunculi 2-2.5 mm longi.

George, Veriicordia (Myrtaceae: Chamelaucieae) 289 Figure 13. Holotype of Veriicordia bifimbriata. Scale in cm. 290 Nuylsia Vol. 7, No. 3 (1991) Differs from other species of Verticordia sect. Verticordella especially in the fringe segments of the petals being themselves fimbriate and in the thick hypanthium appendages with acute free apex. Leaves narrowly elliptic, 1.5-4 mm long. Peduncles 2-2.5 mm long. Hypanthium 2-2.5 mm long. Sepals 5-6 mm long with 6 or 7 lobes, auriculate. Petals 5. 5-6.5 mm long with fringe to 2.5-3 mm long. Stamens 3 mm long. Staminodes 1.5-1.6 mm long. Style 5-6 mm long. Distribution and habitat. Occurs between Mogumber, New Norcia and Bindoon , with a record W of York and a single plant recorded at Boyagin Nature Reserve, Western Australia (Figure 32). Grows in lateritic gravel, sometimes in sand, in eucalypt open woodland. Flowering period. Late November-January; one record in March and one in early April. Conservation status. 2E. Known from few populations in an area being increasingly cleared. Etymology. From the Latin bi- (two) and fimbriatus (fringed), in reference to the fringe of the petals. The bifimbriate petal fringe distinguishes this species and V. paludosa among the pink-flowered taxa of sect. Verticordella. V. bifimbriata may be distinguished from V. paludosa especially by the presence of auricles to the sepals, by the reflexed appendages of the hypanthium being free from the hypanthium towards their apices and by the slightly larger flowers. The habitats also differ. The collections from W of York and Boyagin are atypical in having the petal fringe only slightly bifimbriate. Verticordia blepharophylla A.S. George, sp. nov.

Differs from V. brevifolia subsp. brevifolia in the larger flowers. Sepals 4-5 mm long. Petals 4-5 mm long. Distribution and habitat. Known from three localities in the Stirling Range National Park, in Chester Pass and N of Mt Trio (Figure 32). Grows in gravelly sandy loam in open woodland of Eucalyptus marginata and in sandy loam with mallee shrubland. Flowering period. October. Conservation status. 2RC. The known records are all within a National Park. Etymology. From the name of the Stirling Range with the Latin suffix -ensis (indicating origin or place). The staminodes are usually narrower than those of subsp. brevifolia. Verticordia brownii (Desf.) DC., Prodr. 3: 209 (1828). Chamelaucium brownii Desf., Mem. Mus. Hist. Nat. 5: 271, t.l9 (1819). Lectotype (here chosen): Lucky Bay (E of Esperance, Western Australia), January 1802, R. Brown s.n. (FI; isolecto: K, NY). 294 Nuytsia Vol. 7, No. 3 (1991) Typification. The lectotype is one of two specimens on a sheet at FI. It matches Desfontaines’ plate. The sheet bears a label ‘ ‘Ex Herb. Desfontaines”, another stating ‘ ‘Chamelaucium brownii mem. du mus.” [sic], possibly in Desfontaines’ hand, and one with collection details in Brown’s hand. The sheet at K has the Iter Australiense number 4568. The name is here restricted to the pink-flowered plants occurring between Hopetoun and Mt Ragged. The widespread inland taxon previously included within V. brownii is described below as V. eriocephala. Verticordia capillaris A.S. George, sp. nov. Ad Verticordiam eriocephalam A.S. George affmis, a qua folds semiteretibus longioribus, hypanthio ad basin densiore hirsuto, et petalis extus dense pubescentibus, differt; etiam ad V. polytricham Benth. affinis, a quapraecipue floribus minoribus, hypanthio supra medium multo constricto, et stylo gracili recto glabro ad apicem purpureo, differt. Typus: along road to The Loop, Kalbarri National Park, Western Australia, c. 27° 37' S, 1 14° 22' E, 18 October 1984, A.S. George 16385 &R. Wemm (holo: PERTH; iso: CANB, K, MEL). Related to V. eriocephala A.S. George, from which it differs in the longer semiterete leaves, the hypanthium more densely hirsute towards the base, and the petals densely pubescent outside. Also related to V. polylricha Benth. , from which it differs especially in the smaller flowers, the hypanthium prominently constricted above the middle and the slender glabrous style that is purple towards the apex. Distribution and habitat. Occurs from the southern part of ‘Cooloomia’ S and SE through Kalbarri National Park and Yuna to S of Mullewa, Western Australia (Figure 32). Grows in sand and sandy loam over laterite, in low and tall shrubland. Flowering period. October-November. Conservation status. Not rare or endangered. Etymology. Named from the Latin capillaris (hair-like) in reference to the very slender style. The most distinctive feature of Verticordia capillaris is its very slender, almost translucent style that is purple-tipped. The plants tend to be flatter-topped than those of V. polytricha and V. eriocephala, and the flowers are whiter. Many collections of the species have been determined previously as V. polytricha. Bob and Betty Wemm, of Geraldton, W.A., were the first to recognise the distinct character of the new species. Verticordia carinata Turcz., Bull. Soc. Imp. Naturalistes Moscou 22, 2: 19 (1849). Type: south- western Western Australia, 184-, J. Drummond 4: 46 (holo: KW; iso: BM, CGE, FI K - 4 sheets, P). Figure 15. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 295 Verticordia carinata is here restored as an accepted species. It resembles V. lindleyihut is an open shrub to 1 m tall with arching branches and long-pedunculate flowers. Until recently the species was unknown apart from the type collected in the 1840s (Figure 1) and was thought to be possibly extinct. On 5 March 1990, however, during a survey in the Stirling Range National Park, Mr Allan Rose collected a Verticordia that proved to be this species. The locality was further studied by Elizabeth George and Margaret Pieroni on 13 May, when the plants were still in flower. There is a single population of c. 1 000 plants, hence the conservation status would be 2RC, although the area is affected by dieback (Phytophthora sp.) and the species could be considered vulnerable. Since James Drummond passed through the Stirling Range in the course of the expedition on which he made his 4th Collection this may well be the same population that he found. The new material matches the type well. A diagnosis is given below. Of particular interest in V. carinata is the flower which proves to be somewhat zygomorphic. The flower is held horizontally. The hypanthium and sepals are regular, but the petals, androecium and style all are irregular in arrangement. Of the petals, the two lower (abaxial) are ± erect relative to the hypathium (somewhat in the manner of the keel petals of a pea flower), while the upper three are widely spreading. Seven stamens, those toward the upper side of the flower, are upturned, one each side of the style curves laterally, and the tenth lies along the lower side of the style. The style itself is curved gently downwards to lie between the tower petals with its bearded apex exserted and upturned. The floral form appears clearly adapted for a particular pollinator. Elsewhere in the genus the only inclination towards zygomorphy is the excentric curvature of the style that occurs in some species, especially in subg. Eperephes. Leaves elliptic, very concave, loosely stem-clasping, 3-4.5 mm long, ciliate. Flowers spreading to pendulous, in long raceme-tike groups, magenta-pink. Peduncles 5-7.5 mm long. Hypanthium broadly turbinate, 2 mm long, ribbed, slightly verrucose; reflexed appendages rounded, 0.7-0.9 mm long. Sepals 3.5-4 mm long, the lamina 0.7-0.8 mm long; primary lobes 6 or 7, fimbriate; auricles absent, but a few reflexed cilia. Petals ovate, entire or erose, 3.3-4 mm long, 1. 8-2.6 mm wide. Stamens 1. 2-1. 8 mm long, outcurved. Staminodes erect, 1 mm long. Style 6.5-7 mm long, exserted, curved below apex; beard surrounding style, of branched hairs c. 0.4-0.5 mm long. Ovules 6. Distribution and habitat. Known only from the Stirling Range National Park, Western Australia. Grows in sandy loam in tall shrubland. Flowering period. March - May. Verticordia centipeda A.S.

Verticordella by the small groups of small flowers, densely but shortly ciliate leaves, the pitted, obscurely ribbed hypanthium, and the slender auricles of the sepals. A shrub to 50 cm, rarely to 1 m, openly branched. Leaves appressed, 1. 5-2.5 mm long, concave. Peduncles 2-2.5 mm long. Hypanthium 1.5 mm long; reflexed appendages 0.5 mm long, obtuse. Sepals 3.5 mm long. Petals 3.5 mm long including fimbriae to 1 mm long. Style 4 mm long; beard hairs to 0.5 mm long. Distribution and habitat. Occurs from Yuna S to Eneabba, Western Australia (Figure 37). Grows in clay-loam, sandy loam and sand over laterite, in heath. Flowering period. October-December. Conservation status. Not rare or endangered. Etymology. The specific epithet refers to the neatly ciliate leaf margins resembling a millipede or small centipede. This species is related closely to V. auriculata but has much less developed sepal auricles. The hypanthium is shorter. Verticordia chrysantha Endl., Stirp. Herb. Huegel 3: 7 [1838] (1839).

Typification. Selection of a lectotype for this synonym of V. chrysantha is necessary because there are two collections on the type sheet at KW, the second being Gilbert 13. From the position of the specimens and labels it is not possible to determine which is no. 1 1 and which no. 13, and the specimens represent two taxa. One is V. chrysantha, the other the species described below as V. chrysanthella. Correlation of specimens and numbers can be ascertained from the isolectotypes, all of which are V. chrysantha (the BM sheet also bears a specimen of V. grandiflora Endl.).

George, Verticordia (Myitaceae: Chamelaucieae) 299 Closely related to V. chrysantha Endl., from which it differs mainly in having a lignotuber and smaller leaves and flowers. Leaves terete or semiterete, uncinate, often warty, 3-8 mm long. Peduncles 6-10 mm long. Sepals 3-3.5 mm long. Petals 3-3.5 mm long, up to 15-lobed. Staminodes oblong, usually entire, 1.4-2.3 mm long. Anthers 0.2-0.4 mm long. Style 3-3.3 mm long. Distribution and habitat. Widespread in south-western Western Australia from the Northampton district S through the agricultural regions to Cranbrook and E to Bonnie Rock, Hyden and the Lort River (Figure 35). Usually grows in granitic soil, in heath and low open woodland. Flowering period. September-November. Conservation status. Not rare or endangered. Etymology. From the name of the species’ close relative, V. chrysantha, with the diminutive suffix -ella. Probable synonym. Ferticordjac/!ryj£jnt/iavar.prei5«iSchauer,in J.G.C.Lehmann,Pl.Preiss 1: 102 (Sept. 1844). Type: south-western W.A., October 18-, L. Preiss 178 (holo: LD). This is a variable species that should be studied in more detail. The typical form is common in the central, eastern and north-eastern wheatbelt, usually around granitic rocks. Here it is readily distinguished from V. chrysantha by its multi-stemmed habit and smaller leaves and flowers. Populations towards the south coast east of Ravensthorpe tend to be smaller plants with short thick leaves. North of Geraldton the plants have slightly larger leaves and flowers, thus showing a tendency towards V. chrysantha. The presence or absence of a lignotuber in these plants also should be investigated. Specimens of this species have previously often been determined as V. preissii Schauer, a name correctly applied to a variety of V. acerosa (see above). The holotype of the probable synonym V. chrysantha var. preissii is a small specimen with a single peduncle bearing persistent bracteoles but the flower is missing. From the hispid stem and slender leaves it appears to be V. chrysanthella. The varietal epithet cannot be used at specific rank since it is preoccupied by V. preissii Schauer.

Drummond 6: 46 (holo: NY; iso: BM, CGE - 2 sheets, E, FI, K - 2 sheets, LD - 2 sheets, NSW, P - 3 sheets, W). The species is characterised by the deep or pale yellow flowers on peduncles 2-4 mm long, prominent reflexed appendages on the hypanthium, sepals 4-6 mm long with 7- 12 lobes, petals 5-7 mm long with an acute or obtuse fringe, staminodes c. as long as the stamens, and an exserted style 5-7 mm long with sigmoid apex and a beard of hairs 0.2-0.5 mm long.

Typus: near Northampton, Western Australia, c. 28° 19' S, 114° 38' E, 13 December 1987, R. & B. Wemm s.n. (holo: PERTH; iso: CANS). Differs from V. chrysostachys var. chrysostachys in the usually recurved leaves, peduncles 2-2.5 mm long, pale yellow flowers, petals 5-6 mm long including acute fimbriae to 1.5-2 mm long, and the style hairs to 0.3-0.5 mm long. Distribution and habitat. Occurs from the Northampton district to Wicherina and E towards Mullewa, Western Australia (Figure 34). Grows in deep yellow sand in heath. Flowering period. Late October-January. Conservation status. 2V. Known from few collections and should be investigated to check rarity. Etymology. From the Latin pallidus (pale) in reference to the flower colour which is paler than that of Verticordia chrysostachys var. chrysostachys. A.S. George, Verticordia (Myrtaceae: Charnel aucieae) 301 The variety shows some variation in most characters. In the Wicherina area there appears to be a hybrid swarm with var. pallida as one original parent and the other V. muelleriana subsp. minor. The plants show great variation in morphology and flower colour and should be studied in detail. They are represented by a number of collections at PERTH. Verticordia citrella A.S. George, sp. nov.

Petals L5-L8 mm long, digitate. Long stamens 1.2 mm long, short 0.8 mm. Staminodes oblong to spathulate, 1.4 mm long, entire to obscurely dentate, obtuse or acute. Style 0.8 mm long. Distribution and habitat. Known from one population, growing in seasonally damp gravel-loam in scrub (Figure 32). Flowering period. October-November. Conservation status. 2EC. The only known population is in a Nature Reserve. Etymology. From the Latin citreus (yellow, lemon-coloured), with the diminutive suffix -ella, in reference to the flowers which are the smallest of the taxa in sect. Chrysoma. This species has much smaller floral leaves and flowers than the closest relative, V. acerosa. The sepals are also reflexed over the hypanthium and the lobes are fimbriate, not plumose as in V. acerosa. Verticordia comosa A.S. George, sp. nov.

Holotype of Verticordia cooloomia. Scale in cm. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 303 Related to V. lepidophylla Meissner, from which it differs in the larger squarrose leaves, larger sepals and petals, prominently fimbriate petals, and shorter style with a comose beard. Leaves 2-4 mm long. Sepals 4 mm long. Petals 4 mm long including fimbriae to 1-1.5 mm long. Style 4.5-5.5 mm long, with beard hairs to 0.8 mm long. Distribution and habitat. Restricted to a small area between Three Springs and Morawa, Western Australia (Figure 34). Grows in yellow sand and in greyish-yellow sand over gravel, in heath. Flowering period. October-December. Conservation status. 2E. The few records are from road verges in a heavily-cleared area. Etymology. From the Latin comosus (having a tuft of hairs) in reference to the hairs of the style. The species is closely related to V. lepidophylla in having channelled, slightly flared staminodes and small lemon-yellow flowers. The petals, however, are prominently fimbriate, the leaves squarrose, the sepals and petals slightly larger but the style shorter with a tufted beard. The two species are geographically disjunct. In one collection (23.5 km NE of Three Springs, 28 October 1981, C. Chapman s.n., (PERTH)), the leaves are almost appressed, 2-4 mm long and white- margined, the flowers are creamy white, and the style hairs are less tufted. This may be a hybrid between V. comosa and V. spicata subsp. squamosa. Verticordia cooloomia A.S. George, sp. nov. Species bene distincta, ad Verticordiam sect.

Two populations are known. Etymology. Cooloomia is the name of the area in which the species occurs. The flowers have a strong unusual perfume that persists in dried specimens. Verticordia coronata A.S. George, sp. nov. Ad Verticordiam chrysantham Endl. affinis, a qua lignotubero, foliis floralibus ellipticis-oblongis concavis crassis, hypanthio non vel parce verrucoso, anthera et appendicula aequilonga, et staminodiis magnis latis integris, differt.

Related to V. chrysantha Endl., differing in the presence of a lignotuber, the floral leaves elliptic- oblong, concave and thick, the hypanthium not or slightly verrucose, the anther locules and appendage of equal length, and especially the large broad entire staminodes. Distribution and habitat. Occurs in the Stirling Range National Park W of Chester Pass and N of the range, extending W to Cranbrook and N to the Katanning area. Western Australia (Figure 33). Grows in clay loam, clay and sandy loam, sometimes gravelly, in open mallee shrubland and heath, sometimes in Wandoo woodland. Elowering period. October-November. Conservation status. 2RC. Etymology. From the Latin coronatus (crowned), in reference to the prominent staminodes that form a crown-like centre to the flower after anthesis. The prominent broad entire staminodes distinguish Verticordia coronata from its close relatives V. chrysantha and V. brevifolia. Like the latter species, it differs from V. chrysantha in having a small lignotuber and short, thick leaves. One collection, A.S. George 16591, has the flowers smaller than in typical plants.

From the Greek dasys (hairy, shaggy), and stylos (style), in reference to the very hairy style. Although closely related to V. penicillaris, this species is readily distinguished by the shorter style bearing white hairs for 2/3-3/A its length. V. penicillaris has a style 15-19 mm long with purple hairs only in the upper third. The divisions of the sepal lobes of V. dasystylis are not divaricate as are those of V. penicillaris. Verticordia dasystylis has three subspecies recorded from widely disjunct areas. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 307 Figure 19.

Conservation status. 1E(?X). Searches in 1987 and 1989 failed to locate this population. Etymology. From the Greek oistos (arrow) and poieo (to make or work), in reference to the name of the Arrowsmith River. The short staminodes readily distinguish this subspecies. Verticordia densiflora Lindley, Sketch Veg. Swan R. vi (1839). Lectotype (here chosen); Swan River, W.A., 183-, J. Drummond s.n. (CGE). Typification. The sheet annotated by Lindley at CGE bears three collections, all of which fit the description in the protologue. Drummond’s specimen is the best and is selected as lectotype. The syntypes, also from the Swan River, are annotated with the collectors’ names Toward and Mangles. Like Verticordia plumosa, V. densiflora is extremely widespread and variable. It is here divided into five varieties based on differences in habit, leaves and flower size. Verticordia stelluligera is here transferred to V. densiflora as a variety. Its floral morphology is similar, and the taxon described below as var. roseostella is a connecting link with the other varieties. 310 Nuytsia Vol. 7, No. 3 (1991) Key to varieties la Longest peduncles 5-9 mm long; sepals 3.8-4 mm long; petals 1.6-2 mm long \ai. pedunculata A.S.

A.S. George Verticordia densiflora Lindley var. densiflora Shrub to 80 cm tall with open main branches but usually dense corymb-like flowering branchlets. Floral leaves linear to ovate, 0.8- 1.3 mm wide. Peduncles 1. 5-2.5 mm long. Style 5-6 mm long. Distribution and habitat. Widespread in south-western Western Australia from near Geraldton to Collie, and inland to Wongan Hills, Tammin and Ongerup. Grows in sand, sandy loam, clay and gravelly soil, often on low-lying flats, in shrubland and woodland. Flowering period. October-January. Conservation status. Not rare or endangered. The typical form of Verticordia densiflora var. densiflora is that occurring on the coastal plain west of the Darling Scarp. This has narrow floral leaves. Inland populations tend to have shorter, broader floral leaves; these and some northern collections show a gradation towards var. cespitosa in the slightly larger flowers, e.g.Northam, 1900, J.H.G re gory (PERTVi). Some northern populations have broader floral leaves, thus tending towards var. roseostella. Verticordia densiflora Lindley var. cespitosa (Turcz.) A.S. George, comb, et stat. nov. Verticordia Turcz., Bull. Soc. Imp. NaturalistesMoscou 20: 157(1847). Type: south-western Western Australia, 1842,7. Gilbert 330 (holo: KW). Shrub with fire-tolerant rootstock and several stems to 70 cm tall, or without rootstock and to 1 m tall. Flowers in corymb-like groups. Floral leaves 1-1.5 mm wide. Peduncles 2-3 mm long, sometimes to 4 mm. Sepals 2.5-3.5 mm long. Petals 1.2- 1.9 mm long. Style 5-6 mm long. Distribution. Widespread in south-western Western Australia from Eneabba to the Kalgan Plains and E to Dowerin and Ravensthorpe (Figure 38). A.S. George, Verticordia (Myrlaceae: Charnel aucieae) 311 Flowering period. October-January. Conservation status. Not rare or endangered. This taxon requires further study to determine whether it should be divided. Typical Verticordia densiflora var. cespitosa has a fire-tolerant rootstock from which it sprouts after fire. It then develops several stems to 70 cm tall. The flowers, in the few specimens seen with such a rootstock, are slightly larger than those of many other collections here placed in the variety. Most southern collections have these larger flowers and possibly are from plants with persistent rootstocks, but there is no indication that this is so either from the specimens or from the collectors’ notes. Collections with recorded persistent rootstocks include (besides the type); Mt Saddleback, 30 January 1981, D. Halford 810191 (PERTH); 7 miles [c. 11 km] ENE of Yanchep Forestry Headquarters, 27 January 1965, Y. Chadwick 2559 (PERTH); near Wadjekanup River, NW of Tambellup (in bud), 5 November 1986, A.S. George 16880 & E.A. George (PERTH). Northern populations have flowers with sepals usually 2.5-3 mm long. The floral leaves are also sometimes broader, indicating a tendency towards var. roseostella, e.g. 19 km WS W of Winchester, C. Chapman (PERTH). Intermediate between Verticordia densiflora var. cespitosa and var. densiflora are: 4.8 km E of Gunyidi, 16 January 1982, P. Armstrong 82/7 (PERTH); Hindmarsh Reserve, 19 November 1983, M. Smith 71 (PERTH). The epithet was spelt cespitosa by Turezaninow both in the protologue and on the holotype sheet. Verticordia densiflora Lindley var. pedunculata A.S. George, var. nov.

Known from few collections from road verges in a well-cleared area. Etymolo gy. From the Latin pedunculatus (pedunculate), in reference to the long peduncles which are a distinctive character. The variety in its typical form is known from only two collections. Another collection. Lake View Road, 33 km Eof Manjimup, 29 December 19S3, A.R.Annels 1767 (PERTH), is tentatively included in the variety; it has the same large flowers but the longest peduncles are 5 mm long.

Differs from var. densiflora and var. cespitosa in the openly branched habit and broader floral leaves. A shrub to 1.3 m. Floral leaves narrowly ovate, 1.5-2 mm wide. Peduncles usually 2-4 mm long. Sepals 2.3- 2.6 mm long. Distribution and habitat. Occurs from the Kalbarri area S to the Winchester area (Figure 39). Grows in deep sand and sand over gravel, in tall shrubland. Flowering period. October-December. Conservation status. 3R. Etymology. From the Latin roseus (rose-pink) and Stella (a star), in reference to the flower colour and the similarity of the taxon to Verticordia densiflora var. stelluligera. This variety forms a morphological and geographical link between the yellow-flowered var. stelluligera and the other varieties, all of which are pink-flowered and occur mostly to the south.

Grows in deep sand in shrubland. Flowering period. October-December. Conservation status. Not rare or endangered. This taxon is here reduced to varietal status within V. densiflora. The floral morphology is very similar to that of the other varieties, and only flower colour is a reliable difference from var. roseostella. Some collections have larger flowers (sepals 3-3.2 mm long, petals 2-2.3 mm long), e.g. W of Morawa, 27 October 1981, A. Heitman & A. Lane (PERTH); Kalbarri, 17 October 1979, R. & B. Wemm s.n. (PERTH). A population at Wicherina contains both cream- and pinkish-flowered plants. Verticordia dichroma A.S. George, sp. nov.

Leaves usually 2-3 mm long. Sepals 4 mm long. Petals 5-6 mm long with fringe to 2 mm long. Distribution and habitat. Occurs mainly in the northern part of this species’ range, extending N to W of Billabong Roadhouse, Western Australia (Figure 37). Grows in yellow and red sand in shrubland. Flowering period. October-November. Conservation status. 2RC. Etymology. From the Greek syntomos (shortened), in reference to the smaller groups of flowers and the slightly smaller leaves and flowers.

Lectotype (herechosen); south-western Western Australia, IS4-,J. Drummond 5: 1 12 (KW; isolecto: BM, FI, K - 3 sheets, NSW, W). Typification. The two syntype collections of V. endlicheriana represent the same taxon but are somewhat different in floral morphology. That selected as lectotype agrees more closely with A.S. George, Verlicordia (Myitaceae: Chamelaucieae) 315 Figure 20. Holotype of Verticordia dichroma var. dichroma. Scale in cm. 316 Nuytsia Vol. 7, No. 3 (1991) Schauer’s protologue as follows: petals 7-lobed (8- or 9-lobed in Preiss 179); staminodes tapering though not acuminate (obtuse in Preiss 179). Preiss 181 also has lower lateral branchlets with terete leaves, whereas Preiss 179 has only a single small branchlet with few leaves. A lectotype is selected for V. hirta since the sheet at KW does not bear Turczaninow ’s annotation. It represents the same variety of the species as typical V. endlicheriana. Verticordia endlicheriana is here restored as an accepted species. Lack of recognition of the species has been responsible for some of the problems of identification that have beset the acerosa - chrysanlha group for many years, problems compounded by variation within the species themselves. V. endlicheriana is closely related to V. acerosa in having caducous bracteoles and a ribbed warty hypanthium but is distinguished from that species especially by its broader-based hypanthium and oblong obtuse entire staminodes. The species is widespread in inland south-western Western Australia from Mt Adams and Perenjori S to Mt Barker and E to Narembeen and the Hamersley River. There is considerable variation within the species, here recognised in five varieties. Key to varieties la Petals 3.8-4. 5 mm long, the lamina 1.3-1. 5 mm long; sepals 3.5-4 mm long var. major A.S.

Grows in gravel, gravelly sand and sandy loam, in heath. Flowering period. September -October. Conservation status: 3V. Etymology. Named from the Latin manus (hand) with the diminutive suffix -iculus, in reference to the appearance of the petals. Verticordia endlicheriana var. manicula has the smallest flowers of the varieties of this species. It also flowers earlier than the others, being almost over by the time var. compacta and southern varieties flower. At one locality E of Gunyidi, var. manicula and var. compacta are sympatric.

Type: Mount Barker, Western Australia, 34° 39' S, 1 17° 39' E, 6 December 1964, A.S. George 6457 (holo: PERTH). Differs from all other varieties of V. endlicheriana in the longer, narrower floral leaves (4-8 mm long, 0.5- 1mm wide), and from var. endlicheriana - its nearest relative - in the smaller flowers (sepals 2-2.3 mm long, petals 2-2.5 mm long). Distribution and habitat. Occurs on Mt Barker, growing in loam among granite rocks, in heath (Figure 40). Flowering period. November-December. Conservation status. 2V. Currently known from a single locality. Etymology. From the Latin angustus (narrow) and folium (leaO, in reference to the floral leaves. The collections from Mt Barker are quite consistent morphologically, but one from an unknown locality by Baxter (labelled King George Sound, BM) has larger flowers - sepals 3.5 mm long, petals 4.5 mm long.

DC. affinis, a qua floribus albis vel cremeis, hypanthii dimidio inferiore quam superiore majore et pilis basalibus longioribus, staminibus et staminodiis gracilioribus, et stylo breviore (3 .5-4.5 mm longo) graciliore glabra, differt. Typus: Tomkins Road, S of Mt Adams Road, N of Eneabba, Western Australia, 29“ 26' S, 1 15“ 1 1' E, 30 October 1985, A.S. George 16562 & E.A. George (holo: PERTH; iso: CANB). Closely related to V. brownii, from which it differs in the white or cream flowers, the lower part of the hypanthium larger than the upper and with longer basal hairs, the stamens and staminodes more slender, and the shorter (3.5-4.5 mm long), more slender, glabrous style. Distribution and habitat. Widespread in south-western Western Australia from the Mt Adams area S to Moora, through Wongan Hills to Borden, and E to Boorabbin and Salmon Gums; also recorded near Mt Ragged and Point Culver (Figure 36). Grows in sandy loam in heath, occasionally in low open woodland. Flowering period. Late October-December. Conservation status. Not rare or endangered. Etymology. From the Greek erion (wool) and cephala (head), in reference to the compact massing of flowers over the top of the plant. 320 Nuytsia Vol. 7, No. 3 (1991) This taxon has long been included within Verticordia brownii, but that name is now restricted to the pink-flowered plant that occurs near the south coast from S of Ravensthorpe to Mt Ragged. Verticordia eriocephala differs in having cream or white flowers, the hypanthium wider in the lower half, the stamens and staminodes more slender, and the style glabrous. Mature plants are usually larger than those of V. brownii. East of Salmon Gums the records are scattered: at one locality SE of Mt Ragged the species has been recorded with V. brownii. Verticordia etheliana C. Gardner, J. Roy. Soc. Western Australia 27; 190 (1943). Lectotype (here chosen): between Yaringa and Northampton, Western Australia, 15 September 1940, W.E. Blackall 4714 (PERTH; isolecto: PERTH - 4 sheets). Typification. The five type sheets at PERTH are of the same collection but there is some confusion in the label data, hence a lectotype is selected. This is a sheet with both a label in Gardner’s hand and a typed label; it also bears pencil sketches of floral details by Gardner. A second sheet has similar labels. A third has three small specimens annotated by Gardner but without full collection data; the date with one specimen is wrongly cited as 1938. The fourth sheet has a label in BlackaU’s hand. In the protologue the collector’s number was wrongly given as 4724. According to Blackall’s collecting book at PERTH, the type locality is 30 miles (c. 48 km) N of Galena on the Carnarvon road (now North-West Coastal Highway). The fifth sheet is from Gardner’s private herbarium which was willed to the Benedictine Community in New Norcia and, in June 1970, transferred to the Western Australian Herbarium. This bears a small specimen plus fragments in a packet. It is annotated in Gardner’s hand, with the correct locality and collector’s number but the wrong date of collection. Although this sheet is annotated ‘ ‘Typus” by Gardner, it is not selected as lectotype since he stated in the paper of 1943 that Blackall had donated to the [then] State Herbarium the “specimens which form the type material of many of the species herein described”. Verticordia etheliana can be divided into two varieties on the basis of leaf and flower size. Most northern populations represent var. etheliana, but there is geographical overlap with the smaller variety which extends SSE towards Mullewa. Key to varieties Leaves 3-5 mm long; peduncles 6-10 mm long; sepals 9-10 mm long; petals 6-10 mm long; style 16-20 mm long var. etheliana Leaves 2-3 mm long; peduncles 3-5 mm long; sepals 7-8 mm long; petals 6-7 mm long; style 12-15 mm long \ar.formosa A.S. George Verticordia etheliana C. Gardner var. etheliana Openly branched shrub to 1.5 m. Leaves orbicular, 3-5 mm long. Flowers in small groups below branchlet apices, mostly opening concurrently. Peduncles 6-10 mm long. Sepals 9-10 mm long, red. Petals 6-10 mm long, pink grading to cream at base but all reddening with age. Style 16-20 mm long. Distribution and habitat. Occurs in the eastern part of Kalbarri National Park, Western Australia (Figure 35). Grows in yellow and yellow-brown sand in tall shrubland. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 321 Flowering period. October-November. Conservation status. Not rare or endangered. Verticordia etheliana var. formosa A.S. George, var. nov. Ab Verticordia ethelianaC. Gardner var. etheliana habitu compactiore, foliis, pedunculis, petalis et stylo brevioribus, differt. Folia 2-3 mm longa. Pedunculi 3-5 mm longi. Sepala 7-8 mm longa.

Differs from var. etheliana in the more compact habit, and the smaller leaves, peduncles, petals and style. Leaves 2-3 mm long. Peduncles 3-5 mm long. Sepals 7-8 mm long. Petals 6-7 mm long. Style 12-15 mm long. Distribution and habitat. Extends from the eastern part of Kalbarri National Park (N of the Murchison River) SE to Yuna and almost to Mullewa (Figure 35). Grows in yellow and reddish sand in tall shrubland. Flowering period. September-November. Conservation status. Not rare or endangered. Etymology. Named from the Latin formosus (well formed, handsome) in reference to the more compact, showy habit. Verticordia fastigiata Turcz., Bull. Cl. Phys.-Math. Acad. Saint-Petersbourg 10: 327 (1852).

Other syntype: swampy places near East Mt Barren, no date, G. Maxwell s.n. (K). Typification. The lectotype sheet was annotated by Bentham as V. conferta, while the syntype was labelled by him “V. conferta Benth. var.”, indicating that he considered the latter atypical. Drummond 5: 1 14 is also the type of V. fastigiata Turcz. of which name the specimen at KW is the holotype. Verticordia fimbrilepis Turcz., Bull. Soc. Imp. Nat. Moscou 20: 158 (1847). Type: south-western Western Australia, 184-, /. Drummond 3: 24 (holo: KW; iso: BM, CGE, K - 3 sheets, MEL, NSW, W). The sheet at MEL is unnumbered but matches the other specimens. Drummond collected the species only once. 322 Nuyisia Vol. 7. No. 3 (1991) This species, one of the rarest in the genus and for more than a century known only from the type, was re-discovered in 1983 by Mr Norm Stevens, of Ongerup, Western Australia. In the same year a new subspecies was discovered on the Kent River by Mr Tony Annels, Manjimup. It differs from the typical subspecies in the length of the peduncles and in the petals and staminodes. Key to subspecies Peduncles 2-4 mm long; petal lamina 1.3-1. 5 mm wide; staminodes with a long apical cilium Peduncles 5-15 mm long; petal lamina 0.9-1 mm wide; staminode fringe of ± equal segments Verticordia fimbrilepis Turcz. subsp. fimbrilepis Peduncles 2-4 mm long. Petal lamina 1.3- 1.5 mm wide, fimbriate. Staminodes fimbriate across broad apex, one cilium much longer than the others. Distribution and habitat. Occurs W of Woodanilling, Western Australia (Figure 33). Grows in sandy loam over gravel in heath. Flowering period. November-December. Conservation status. 2E. Three small populations are known, all on road verges. Verticordia fimbrilepis subsp. australis A.S. George, subsp. nov. Ab subspecie typica pedunculis 5-15 mm longis, lamina petalorum 0.9-1 mm lata laciniata, et staminodiis per apicem et margines laterales superos fimbriatis sed sine cilia apicali longa, differt. Typus: Break [forestry] Road crossing, Kent River, Western Australia, c. 34° 50’ S, 117° 03' E, 5 November 1985, A. 5. George 16579 & E.A. George (holo; PERTH; iso: CANB, K, MEL). Differs from the type subspecies in the long peduncles 5-15 mm long, the laciniate petals 0.9-1 mm wide, and the staminodes fimbriate across the apex and lateral margins but without a long apical cilium. Distribution and habitat. Known from two localities, one on the Kent River NW of Denmark, the other on Mt Willyung N of Albany (a single young plant recorded) (Figure 33). Grows in granitic soil in low open heath. Flowering period. Late October-November. Conservation status. 2RC. The type locality is within State forest. suhsp. fimbrilepis subsp. australis A.S. George A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 323 Etymology. The Latin australis (southern) refers to the geographical distribution relative to that of Verticordia fimbrilepis wtosp. fimbrilepis. The longer peduncles give the flowering branchlets a more open aspect than that of Verticordia fimbrilepis subsp. fimbrilepis. In addition the petals are narrower and more deeply and coarsely fringed, while the staminodes are fringed on the upper lateral margins as well as across the apex but lack the long terminal cilium of suhsp. fimbrilepis. The subspecies may occur on other granitic hills in the area. Verticordia fragrans A.S. George, sp. nov. Ab speciebus aliis Verticordiae sect.

Differs from the other species of Verticordia sect. Pennuligera in the pale pink and white fragrant flowers, the broad lobes of the sepals, and the prominent petals entire along the upper margins. A shrub to 2.5 m tall, openly branched. Leaves elliptic to obovate, 1.5-4 mm long, semiamplexicaul. Peduncles 1.5-3 mm long, thickened. Hypanthium 3 mm long, verrucose, glabrous; appendages broad, thick. Sepals 3.5-4 mm long, with 6-9 plumose lobes, the auricles orbicular, fimbriate. Petals orbicular with ciliate auricles, 4-4.5 mm long, erect, entire but towards base ciliate, united with androecium. Stamens 3.5 mm long; staminodes oblong, acute, incurved, 3 mm long, glandular. Style 5 mm long, curved below apex, bearded. Ovules 10. Distribution and habitat. Restricted to a small area near Eneabba, south-western Western Australia (Figure 36). Grows in deep white sand with tall shrubland, occasionally with low open woodland of Eucalyptus todtiana. Flowering period. October-November. Conservation status. TV. Etymology. The Latin fragrans refers to the scented flowers. A distinctive species especially in the prominent, mostly entire petals and the broad sepal lobes. 324 Nuytsia Vol. 7, No. 3 (1991) Figure 2 1 .

Typus: The Loop, Murchison River, Kalbarri National Park, Western Australia, 27“ 34' S, 1 14“ 27' E, 18 October 1984, A.S. George 16389 & R. Wemm (holo: PERTH); same locality, collectors and number (syn: CANS, K). Closely related to V. chrysantha, from which it differs in the longer peduncles (12-20 mm long), the larger hooded inflated anther appendage (0.5-0.8 mm long), and the narrowly triangular staminodes. Distribution and habitat. Recorded only from the Murchison River gorge at The Loop, Kalbarri National Park (Figure 34). Grows in red sand among sandstone rocks, in open shrubland. Flowering period. October. Conservation status. 2RC. Etymology. From the Latin galeatus (hooded), in reference to the large cucullate appendage of the anther. The species is closely related to V. chrysantha but is easily distinguished by the large inflated appendage of the anther. The peduncles are long and slender, and the leaves also are longer than those of most collections of V. chrysantha. The acute staminodes are a further difference, those of V. chrysantha typically being obtuse and slightly lobed. Verticordia gracilis A.S. George, sp. nov. Ad Verticordiam pritzelii Diels affinis, a qua ramis et pedunculis gracilioribus; hypanthio pilosiore; sepalis brevioribus, plus divisis sed lobis reflexis nullis; petalis orbicularibus eroso-dentatis; antheris compressis; et ovario magis profunde inserto, praecipue differt. Typus: Nof Mt Holland Western Australia, c. 32" 05' S, 1 19“ 40' E, 8 November 1984, Af. Smith 130 (holo: PERTH; iso: CANB, K). Figure 22. A distinctive species, probably related to V. pritzelii, but differing in the more slender branchlets and peduncles, the more pilose hypanthium , the shorter more divided sepals but lacking auricles, the orbicular erose-dentate petals, the compressed anthers, and the deeply inserted ovary. Distribution and habitat. Occurs between Bruce Rock and Hyden and east to the Mt Holland area (Figure 32). Grows in yellow sand and gravelly sand in heath. 326 Nuytsia Vol. 7, No. 3 (1991) Figure 22. Holotype of Verticordia gracilis. Scale in cm. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 327 Flowering period. Late October-November. Conservation status. 2R. Etymology. The Latin gracilis (slender) refers to the slender stems and peduncles. The species is related to Verticordia pritzelii, having a similar habit, leaves and style. It is more slender, however, and is easily distinguished by the lack of reflexed lobes to the sepals. The sepals are more finely divided, and the petals are shortly dentate to erose. Although the androecium is similar, the anthers of V. gracilis differ in being vertically compressed. The flowers are cerise, fading to pink. The species is considered distinct enough to warrant a new section (see above). Verticordia grandis J.L. Drumm., Hooker’s J. Bot. Kew Card. Misc. 5: 119 (1853) Lectototype (here chosen) : south-western Western Australia, 1849-50, J. Drummond 6: 44, (K; isolecto: BM, CGE - 2 sheets, E, K - 2 sheets, W). Typification. There is no specimen annotated by Drummond who described the species in a letter to W. Hooker. He made only one collection, the specimens of which mostly have long stems with many flowers, as described by him. Because there is some variation, especially in leaf size, a lectotype is chosen, being the specimen with Drummond’s number tag 44 attached, on the sheet at K presented by W.W. Saunders. Verticordia habrantha Schauer, in J.G.C. Lehmann, PI. Preiss. 1: 1(X)(1844). Type: near Gordon River, Hay District, Western Australia, November 18-, L. Preiss 169 (holo; LD; iso: MEL). Verticordia umbellata Turcz., Bull. Soc. Imp. Naturalistes Moscou 20, 1: 159 (1847). Lectotype (here chosen): south-western Western Australia, 1S4-,J. Drummond3: 25 (KW; isolecto: BM,CGE, FI, K - 3 sheets, MEL, NY, W). Typification. A lectotype is selected for V. umbellata since the sheet at KW, although probably seen by Turczaninow, is not annotated by him. Verticordia habrantha is variable but further study is needed to determine if it should be formally divided. Some plants have a small lignotuber, several erect stems, and flowers with petals up to 5 mm long. Others have no lignotuber, a single basal stem, widely but openly branched above, and flowers with petals down to 2.8 mm long. In flower size there is a range from one extreme to the other. Verticordia halophila A.S. George, sp. nov. Ad Verticordiam pennigeramEndl. arete affinis, aqua habitu erecto magis ramoso, foliis crassis, pedunculis brevioribus, petalis minus connatis, staminodiis brevioribus, stylo longioribus et ovulis minus numerosis, differt; etiam ad V. lindleyi Schauer affinis, a qua foliis crassis, pedunculis brevioribus, petalis grosse fimbriatis, staminis staminodiis que longioribus, stylo longiore, et ovulis minus numerosis, differt. Pedunculi 0.5-1 mm longi. Sepala4-5 mm longa. Petala 3.5-4 mm longa. 328 Nuytsia Vol. 7, No. 3 (1991) breviter et grosse fimbriata. Stamina 1.5-1. 6 mm longa; staminodia 1.4-1. 5 mm longa. Stylus 5-5.6 mm longus. Ovuli 6. Typus: S of Coorow, Midlands Hwy, Western Australia, 29“ 58’S, 116“ 05’E, 31 October 1985, AS. George 16570 & E.A. George (holo: PERTH; iso: AD, CANB, K, MEL, NSW). Closely related to Verticordia pennigera Endl., from which it differs in the erect, more bushy habit, the thick leaves, shorter peduncles, less connate petals, shorter staminodes, longer style and fewer ovules; also related to V. lindleyi Schauer, from which it differs in the thick leaves, shorter peduncles, coarsely fimbriate petals, longer stamens and staminodes, longer style and fewer ovules. Peduncles 0.5-1 mm long. Sepals 4-5 mm long. Petals 3.5-4 mm long, shortly and coarsely fimbriate. Stamens 1.5-1.6 mm long; staminodes 1.4-1.5 mm long. Style 5-5.6 mm long. Ovules 6. Distribution and habitat. Occurs in the Coorow area (Figure 37). Grows on subsaline flats in open woodland and shrubland. Flowering period. Mid-October-November. Conservation status. 2E. Only two populations are known, both of which could be threatened by clearing or an increase in soil salinity. Etymology. Named from the Greek hals (salt) and -philus (loving), in reference to the habitat which is unusual in the genus. Plants of this species have a twiggy habit and a distinct red tinge to the leaves. The flowers are mostly pale pink with the sepals grading to dark red on the lamina. The species was discovered by the late Charles Chapman. Verticordia harveyi Benth., FI. Austral. 3: 22 (1867). Lectotype (here chosen): near Cape Riche, Western Australia, March 1854, W.//. //arvey s.n. (K) (Figure 23). Ot/ier sy/ifype: ?same locality, 18-, G. Maxwell s.n. (BM). Typification. The lectotype sheet (Figure 23) is annotated in Bentham’s hand and the collector is commemorated in the specific epithet. Only two collections (besides the types) had been made of this species, one in the 1950s near Manypeaks (S.P. Pfeiffer, PERTH), the other without locality or collector (NSW), until its rediscovery in March 1991 by Mr Norm Stevens. Verticordia helichrysantha F. Muell. exBenth.,Fl. Austral. 3: 21 (1867). Lcctorype (here chosen): Phillips Range, Western Australia, 18-, G. Maxwell s.n. (MEL; isolecto; K, MEL). Other syntype: Cape Riche and South West Bay, Western Australia, 18—, G. Maxwell s.n. (K, MEL). Typification. The specimen selected as lectotype is accompanied by Mueller’s epithet in his hand (“inedit”), and fits the protologue better than the syntype in having larger flowers (10 mm wide) agreeing with the protologue (‘ ‘nearly 1/2 in. diameter’ ’ ). It also bears a dissected flower which may have been examined by Bentham. The syntype has flowers 8-9 mm diam. A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 329 Figure 23.

Neotype (here nominated): between Yellowdine and Bronti, Western Australia, Jan. 1927, C.A. Gardner 164 (PERTH). Typification. A lectotype is chosen for V. helmsii because both sheets seen have labels in Moore’s hand. Although he described the style as glabrous his specimens do have the short beard below the stigma that is typical of the species. No specimen of Diels’ collection has been found in material of Verticordia in some 20 herbaria including the Botanisches Museum Berlin-Dahlem (B). The type is therefore presumed lost and a neotype from the same area nominated. Verticordia huegelii Endl., Enum. 46 (1837) Verticordia huegelii is a variable species. Four varieties are here recognised, one under the epithet stylosa first published at specific rank by Turczaninow. This subdivision is based on variations in the form of the staminodes, flower colour, habit and to some extent size. Key to varieties la Staminodes linear-subulate with 1 (rarely 2) teeth each side var. tridens A.S.

The staminodes are usually ovate and finely fringed, but sometimes are narrower with a few slender teeth each side. The hairs of the style are usually white and the stigma is golden yellow, but in populations in the Mt Lesueur area the hairs and stigma are reddish purple. A.S. George. Verticordia (Myrtaceae: Chamelaucieae) 331 Distribution and habitat. Frequent from Mingenew S to Dwellingup and at scattered localities farther inland, including one from ME of Ravensthorpe. Grows in clay and clay-loam, often with laterite or granite, in open heath. Flowering period. September - October. Conservation status. Not rare. Verticordia huegelii var. stylosa (Turcz.) A.S. George, stat. et comb. nov. - Verticordia .ityiosa Turcz.,Bull. Soc.Imp. NaturalistesMoscou20; 160(1847). Lectoty/jc (here chosen): south-western Western Australia, J. Gilbert 'i'll (KW). Typification. The type sheet at KW is not annotated by Turczaninow but the single specimen - a whole young plant - agrees with the protologue. The staminodes are typically ovate but vary to lanceolate, e.g. Darkin Swamp, 12 November 1981, A. Selkirks.n. (PERTH); 7 km S of Pingelly, 4 November 1983, M. Hamilton s.n. (PERTH). Similar to var. huegelii but has yellow flowers and tends to flower later. Distribution and habitat. Occurs in scattered localities from Wongan Hills S to Kojonup (Figure 41). Grows in clay-loam and sandy loam, sometimes rocky, in low heath and open woodland. Flowering period. October - November. Conservation status. Not rare. Verticordia huegelii Endl. var. decumbens A.S. George, var. nov. Ab varietatibus aliis Verticordiae huegelii caudice ignis tolerabili, habitu graciliore, ramulis decumbentibus, et floribus parce minoribus, differt. Frutex ad 10 cm altus et 30 cm latus. Folia 3- 6 mm longa, 0.4-0.6 mm crassa. Hypanthium 2-2.2 mm tonga. Sepala 7-8 mm longa; lamina 1 mm longa, 1.5 mm lata. Petalorum lamina 1.7-1. 8 mm longa, 1.6- 1.9 mm lata. Stylus 5 mm longus. Typus: Eof Kelmscott, Brookton Highway, Western Australia, c. 32“ 1 T S, 1 16° 15'E, 18 November 1985, D.B. Foreman 1057 (holo: PERTH; iso: AD, CANB, MEL). Differs from the other varieties of V. huegelii in the fire-tolerant rootstock, the more slender habit, the decumbent branchlets and the slightly smaller flowers. A shrub to 10 cm high and 30 cm wide. Leaves 3-6 mm long, 0.4-0.6 mm thick. Hypanthium 2-2.2 mm long. Sepals 7-8 mm long; lamina 1 mm long, 1.5 mm wide. Petal lamina 1. 7-1.8 mm long, 1.6-1.9 mm wide. Style 5 mm long. Distribution and habitat. Recorded from several granitic outcrops from Mundaring to Mt Saddleback on the Darling Plateau E of Perth, Western Australia (Figure 34). Grows in open shrubland. Flowering period. Late October-November. 332 Nuytsia Vol. 7, No. 3 (1991) Conservation status. 2?E. Known from few populations at well-frequented localities, but possibly occurs on a number of granitic outcrops in State forest areas. Etymology. The Latin decumbens refers to the branches. In floral morphology this is similar to Verticordia huegelii var. huegelii but is slightly smaller. The typical variety is, however, an erect or spreading shrub to 40 cm tall and is killed by fire. It also flowers earlier, being almost finished by the time var. decumbens is in full flower. The style hairs are ascending, not spreading. A collection from the Coorow-Green Head Road E of the Brand Highway is probably this taxon. Verticordia huegelii Endl. var. tridens A.S. George, var. nov. Ab varietatibus aliis Verticordiae huegelii Endl. staminodiis plerumque tridentatis differt. Flores citrini, rubescentes. Staminodia subulata sed utrinque l-(raro 2-) dentata. Typus: W of Kamballup, Western Australia, 34“ 32' S, 1 17° 55' E, 26 October 1984, A.S. George 16515 & E. Berndt (holo: PERTH; iso: CANB, K). Differs from the other varieties of V. huegelii in having usually tridentate staminodes. Flowers lemon-yellow turning red. Staminodes subulate but with 1 (rarely 2) teeth on each margin. Distribution and habitat. Occurs from the Wongan Hills district S almost to the Porongurup Range, Western Australia (Figure 34). Grows in gravelly loam and sandy loam, in Eucalyptus wandoo and E. occidentalis low open woodland and shrubland. Flowering period. October-November. Conservation status. 2E. Four small populations are known, all on road verges. Etymology. From the Latin tri- (three) and dens (tooth), in reference to the staminodes. Superficially, this taxon resembles Verticordia huegelii var. stylosa in having initially yellow flowers that turn red. The 3-lobed staminodes easily distinguish it from that variety. Occasionally the staminodes are 4- or 5-lobed. The anthers are smaller than those of var. stylosa and var. huegelii. In one collection from near Wongan Hills the hairs of the style are purple.

George, Verticordia (Myrtaceae: Chamelaucieae) 333 Typus: N of turnoff to East Mt Barren, on Hopetoun - Ravensthorpe road, Western Australia, 24 October 1984, A.5. George 16479 & E.A. Berndt (holo; PERTH; iso: CANB, K, MEL, NSW). Closely related to V. insignis from which it differs in the usually smaller leaves and flowers, the included stamens, the staminodes fimbriate only on the margins, and the short style. Floral leaves 1.5- 3 mm long. Sepals 4-5 mm long. Petals 3-4 mm long. Stamens 0.6-0.7 mm long. Style 0.2-0.3 mm long. Distribution and habitat. Occurs between Fitzgerald and Esperance and inland to Boorabbin National Park, Western Australia (Figure 41). Grows in sandy loam and sand, sometimes over laterite, in heath and open mallee heath. Flowering period. August-November. Conservation status. Not rare or endangered. Etymology. From the Latin inclusus (included), in reference to the stamens and style. Closely related to V. insignis, this species may be distinguished especially by the short included stamens and style. Usually the leaves and flowers are smaller than those of V. insignis; some northern collections (e.g. 51 km SE of Moorine Rock, 22 October 1984, A.S. George 16449, PERTH) have flowers approaching those of V. insignis in size. This species was figured as V. roei by W. Boding Hemsley, Icon. PI. 28: t. 2779 (1905). Verticordia insignis Endl., Enum. PI. 47 (1837). Holotype: Swan River, Western Australia, November-December 1833, K. von Huegel (W; iso: BM). The holotype bears the number 9, but this appears not to be the collector’s number. There is also a dissected flower (late bud stage) and drawings. Verticordia insignis comprises 3 subspecies, distinguished by flower size and colour.

A.S. George 334 Nuytsia Vol. 7, No. 3 (1991) Verticordia insignis Endl. subsp. insignis Shrub to 70 cm, the main stems ascending or widely spreading. Leaves linear, triquetrous, obtuse; upper leaves 3-9 mm long. Peduncles usually 12-25 mm long. Sepals 5-6 mm long, deeply fimbriate, with basal reflexed lobes having upturned densely fimbriate apices that form a comose ring about the hypanthium. Petals 3-4 mm long, the fringe 0.5-1 mm long. Stamens 3.5-4 mm long; anthers 0.2- 0.4 mm long; staminodes 2-3 mm long, fringed. Style 5-6 mm long. Distribution and habitat. Occurs along the Darling Scarp E of Perth, extending inland towards Northam and Brookton, Western Australia (Figure 42). Grows in gravelly and granitic soil, in open woodland. Flowering period. October-November. Conservation status. Not rare or endangered. Verticordia insignis Endl. subsp. eomagis A.S. George, subsp. nov.

George (holo: PERTH; iso: CANB). Differs from the other subspecies of V. insignis in the larger flowers. Sepals 7-9 mm long. Petals 3.5-5 mm long, with fimbriae 1-1.5 mm long. Stamens 5-6 mm long with anthers 0.7 -0.8 mm long. Staminodes 4-4.5 mm long, 0.8-1 mm wide. Style 6-7 mm long. Distribution and habitat. Occurs from an area between Eneabba and Coorow S to the Badgingarra area. Western Australia, with one collection “north of New Norcia” (Figure42). Grows in sand over laterite, occasionally on lateritic rises, in heath. Flowering period. September-early November. Conservation status. 2R. Etymology. From the Latin eo magis (so much the more), in reference to both the larger size and the very attractive appearance of the flowers. The northern populations of Verticordia insignis, here named subsp. eomagis, have consistently larger flowers than those of both typical Verticordia insignis and subsp. compta. Further, the petals are much more concave, and the staminodes are usually pale, in contrast to the red staminodes of the other two subspecies. The hairs on the inner face of the staminodes are very long, almost reaching the style. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 335 Verticordia insignis subsp. compta (Endl.) A.S.

Grows in sand in open woodland and heath. Flowering period. October-November. Conservation status. Not rare or endangered. This taxon clearly belongs with Verticordia insignis. It is similar in size to typical insignis but has smaller upper leaves, shorter stamens and style, and the sepals as well as the petals are bright pink. Verticordia integra A.S. George, sp. nov. Ab Verticordia serrata (Lindley) Schauer foliis oblongis ad obovatis crassis integris, hypanthio minus vemicoso, etpetalis majoribus orbicularibus (3-3.5 mm diam.) integris, praecipue differt. Typus: S of Lake Grace - Newdegate road along Bumgup South Road, Western Australia, 33° 08' S, 118° 48' E, 7 November 1985, A.S. George 16601 & EA. George (holo: PERTH; iso: CANB, K, MEL, NSW, PERTH). Closely related to V. serrata, from which it differs especially in the oblong to obovate thick entire leaves, the less verrucose hypanthium, and the larger, orbicular entire petals (3-3.5 mm diam.). Distribution and habitat. Occurs in the Newdegate area, with one record E of Ravensthorpe, W estem Australia (Figure 35). Grows in sand over laterite, in malice heath. Flowering period. Late October-November. Conservation status. 2R. Etymology. From the Latin integer (whole, entire), in reference to the leaves and petals. Although closely related to V. serrata, this taxon is easily distinguished by its entire leaves and large entire petals. It is relatively consistent morphologically. The flowers have a typical Verticordia scent. 336 Nuytsia Vol. 7, No. 3 (1991) Verticordia interioris C. Gardner ex A.S. George, sp. nov.

Peduncles 4-8 mm long. Hypanthium hemispherical, glabrous, 1.5-2 mm long. Sepals 4-5 mm long, 5-lobed, the lobes deeply fimbriate. Petals united with androecium, elliptic, entire, 5-7 mm long. Stamens 2-3 mm long, the filaments broad, the anthers clavate with a globose connective. Staminodes terete, obtuse, glandular. Style 3-4 mm long, bearded below apex with forked hairs. Ovules 8 or 9. Distribution and habitat. Occurs in scattered localities from Byro Station S to Pindar and Mellenbye Sm near Yalgoo, E to Sandstone and Leonora and S towards Wialki, Western Australia (Figure 35). Grows in open rocky areas on granitic and lateritic hills . Flowering period. Late August-October. Conservation status. 3R. Etymology. From the Latin interior (inner, interior), chosen by the late Charles Gardner to indicate the inland occurrence relative to most other species of the genus. This distinctive species, first collected at Wurarga in 1909 by J.H. Maiden, resembles V. picta Endl. but has 10 fertile stamens. In habit it is sprawling or straggling, the leaves are verrucose, the petals are prominently clawed, the anthers dehisce by large openings, the staminodes are obtuse and the style is unilaterally bearded. There is variation especially in the width of the petals, most north- western specimens having wider petals about 3 mm wide. Verticordia laciniata A.S. George, sp. nov. Ad Verticordiam chrysantham Endl. affmis, a qua foliis canaliculatis breviter ciliatis, staminibus longioribus (3-3.5 mm longis), antherae appendicula majore plicata, et staminodiis subulatis lacini'dtis, differ!. Typus: SE ofWalkaway on Burma Road, Western Australia, 29° 04' S, 1 15° 08' E, 4 September 1966, A.S. George 7856 (holo: PERTH; iso: CANB, K). A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 337 Related to V. chrysantha, from which it differs in the canaliculate shortly ciliate leaves, the longer stamens (3-3.5 mm long), the larger plicate anther appendage, and the subulate laciniate staminodes. Distribution and habitat. Widespread from the Eradu area S to the Green Head-Coorow road. Western Australia (Figure 40). Grows in sand, sometimes over laterite, in low heath. Flowering period. September-October, Conservation status. Not rare or endangered. Etymology. From the Latin laciniatus (divided into narrow, pointed divisions), in reference to the staminodes. This species is related to Verticordia chrysantha Endl. but is easily distinguished by the channelled shortly ciliate leaves and the laciniate staminodes. Occasionally the leaves have few cilia. The stamens are larger than those of V. chrysantha and the anther appendage is also larger, and infolded. The species also resembles V. nobilis Meissner which is common in the same area but which may be distinguished especially by the large bifid anther appendage. Presumed hybrids between V. laciniata and V. nobilis have been recorded (see introductory section on Hybrids, above). Verticordia lehmannii Schauer, in J.G.C. Lehmann, PI. Preiss. 1: 99 (1844). Lectotype (here chosen): ‘Molloy’splain’,south-westem Western Australia, IVDecember 1^39, L.Preiss 166 (LD; isolecto: BM, FI, G). Typification. In the protologue, Schauer cited two localities (“Molloy’s plain districti Sussex, etcirca Sinum Regis Georgii”). both under the Preiss number 166. The collection selected as lectotype agrees better with Schauer’s description. The other collection is the large-flowered variant of Verticordia habrantha Schauer and is probably from the Albany district since this variant of the species does not extend further west than Cranbrook. The lectotype is thus the collection from “Molloy’s plain” which is not a current place name but is probably near the Vasse River where the Molloy family settled in the winter of 1839 (Hasluck 1955). Verticordia lepidophylla F. Muell., Fragm. 1: 228 (1859). Type: Murchison River, Western Australia, 18-, A. Oldfield s.n. (holo: MEL; iso: K - 2 sheets). In its typical form this species is relatively consistent morphologically, varying slightly in the petal margin being more evidently fringed in southern populations (though not as deeply as in V. comosa, described above). Plants near the coast, e.g. Kalbarri, 28 October 1985, A.S. George 16560 & E.A. George (PERTH), are more densely branched and have slightly smaller leaves. North of the Murchison River, there are several populations that have smaller, less fimbriate sepals and entire petals. They are here described as Verticordia lepidophylla var. quantula. 338 Nuytsia Vol. 7, No. 3 (1991) Key to varieties Sepals 3.5-4.5 mm long, divided for c. 2/3 their length into fimbriate lobes; petals dentate to erose at least on lateral margins var. lepidophylla Sepals 2-2.5 mm long, divided less than halfway into shortly fimbriate lobes, or simple with dentate margin; petals entire var. quantula A.S. George Verticordia lepidophylla var. quantula A.S. George, var. nov. Ab Verticordia lepidophylla F. Muell. var. lepidophylla sepalis minoribus (2-2.5 mm longis) minus lobatis (non ad dimidium) et minus fimbriatis, et petalis integris, differ!. Typus: Vermin-proof Fence near Nedge of Murchison House Station, Western Australia, c. 27° 15' S, 1 14° 16' E, 29 October 1986, A.S. George 16844 & E.A. George (holo: PERTH; iso: C ANB, K, MEL, NSW, PERTH). Differs from V. lepidophylla var. lepidophylla in the smaller (2-2.5 mm long) less deeply lobed and less fimbriate sepals and the entire petals. Distribution and habitat. Recorded from two close localities N of Murchison House Station, upper south-western Western Australia (Figure 35). Grows in red sand over limestone in tall shrubland, and in yellow sand in heath. Locally common. Flowering period. October-November. Conservation status. 2V. Etymology. Named from the Latin quantulus (how little), in reference to the shortly lobed and fimbriate sepals. Because the sepals of this variety are short and little-fimbriate, its petals assume a dominant aspect in the flower. In a collection 16 km E of the type locality (29 October 1986, A.S. George 16851, PERTH), the sepals are simple or almost so and shortly fimbriate or dentate. This collection was just beginning to flower; the type is in full flower. It is likely that populations morphologically intermediate between the subspecies will be found between this area and those of typical V. lepidophylla. Verticordia lindleyi Schauer, Nov. Act. Nat. Cur. 19,suppl. 2: 210(1841). - V.drummondiiSchdMex var. lindleyi (Schauer) Benth., FI. Austral. 3: 31 (1867). Typical Verticordia lindleyi is characterised, within Verticordia sect. Verticordella, by the slightly concave shordy ciliate leaves, peduncles 2-4 mm long, a rounded ribbed hypanthium c. 2 mm long with sliort, rounded reflexed appendages, pale pink flowers, sepals 3-6 mm long, petals 3-4.5 mm long and entire to shortly dentate, and a style 3-4 mm long, markedly sigmoid below the apex. The species is common in south-western Western Australia from Gillingarra to Perth, with one collection from the Murray River. There is variation in the leaves from loosely appressed to widely A.S. George, Verticordia (Myitaceae: Chamelaucieae) 339 spreading, in flower size and in the petal apex. Typical plants have sepals 3-4 mm long and petals 3-3.5 mm long. Several collections, from localities over the species’ range, have sepals up to 6 mm long and petals to 4.5 mm long, e.g. V. Mann 19 & A.S. George, Forrestdale (K, PERTH). A new subspecies occurs inland, mainly from Brookton to Cranbrook.

Differs from V. lindleyi subsp. lindleyi in having purple or deep pink flowers, the petals towards the apex broader and coarsely dentate, and the staminodes longer than the stamens. Distribution and habitat. Widespread but scattered from the Brookton area to Cranbrook with outliers W to Darkin Swamp, Hillman, Collie and Tonebridge, Western Australia (Figure 35). Grows in sand, sandy loam and sand over gravel, in heathland and low open woodland, sometimes in low- lying areas. Flowering period. Mainly November-December, but a few later records, including May. Conservation status. 3R. Known populations are mostly on road verges in cleared agricultural areas. Etymology. The Latin epithet refers to the typical flower colour. Verticordia longistylis A.S.

Hypanthium hemispherical, 5 mm long, verrucose, densely hirsute. Sepals 6-7 mm long, much-divided, yellow and purple. Petals ovate, concave, 2.5-3 mm long, usually glabrous except densely fimbriate margins, yellow. Stamens uniform, 3 mm long, glabrous; anthers globular, 0.7 mm long with an inconspicuous appendage. Staminodes linear, 2 mm long, glandular. Style straight, bearded below apex with simple hairs. Ovules 2. Distribution and habitat. Recorded only near the Fitzgerald River E of Roe Rock, Fitzgerald River National Park, Western Australia (Figure 34). Grows on rocky spongolite platform above river valley, in open areas. Flowering period. December- June. Conservation status. 2RC. Etymology. From the Latin longus (long) and stylus (style); the style is the longest in the genus. This distinctive species is related to Verticordia oxylepis which occurs in the same region but more widely. Verticordia longistylis differs especially in the more upright habit, larger leaves and flowers, the petals fimbriate on the margin but otherwise almost glabrous, and the long style. The flowering period is probably long - the type is in early flower, while A.S. George 10001 (collected at the type locality on 13 July 1970), has a few late flowers. Verticordia luteola A.S.

Related to V. bifimbriata, from which it differs especially in the yellow and white flowers, the sepals with more numerous (7-9) lobes but lacking auricles, and the shorter stamens (1.5 mm long). Distribution and habitat. Restricted to an area SW and W of Three Springs, Western Australia, with a collection from near Mt Adams (Figure 41). Grows in sand over gravel, in heath. Flowering period. November-December. 342 Nuytsia Vol. 7, No. 3 (1991) Figure 25. Holotype of Verticordia luteola. Scale in cm. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 343 Conservation status. 2E. Only six collections seen, all from road verges in heavily cleared areas. Etymology. Named from the Latin luteolus (pale yellow) in reference to the dominant flower colour. This is the only species of Verticordia sect. Verticordella with yellow or yellow and white flowers, although V. pholidophylla may be creamish. Morphologically V. luteola closely resembles V. bifimbriala in having moderately large flowers and bi-fringed petals. The reflexed appendages of the hypanthium are more swollen, the sepals have 7-9 lobes and very few reflexed cilia, and the stamens and staminodes are shorter. The collection from near Mt Adams was said to have ‘greenish white’ flowers. Verticordia minutiflora F. Muell., Fragm. 4: 58 (1864). Verticordia fontanesii var. parviflora Benth., FI. Ausu-al. 3: 21 (1867). Lectotype (here chosen): Lucky Bay, [Western Australia] , Jan. 1802, R. Brown Iter Australiense 4572 (K; probable isolecto: MEL). Typification. Besides the lectotype, the type sheet of V. fontanesii var. parviflora bears a collection of V. sieberi Diesing ex Schauer, which has flowers about as large as those of typical V. plumosa (of which V. fontanesii is a synonym). This has the Iter Australiense number 4567. Neither collection has been annotated by Bentham as V. fontanesii var. parviflora, nor has this name been found on any other sheet named by him as V. fontanesii. Since no. 4572 has much smaller flowers it is selected as lectotype. The name is a synonym of V. minutiflora F. Muell. Verticordia mitodes A.S. George, sp. nov.

Sepala 3-4 mm longa, lamina quadrata, auriculis basalibus gracilibus. Petala 4-5 mm longa fimbriis ad 3 mm longis. Stylus 5-6 mm longus; barba pilis 0.2-0.4 mm longis. Typus: Bronti, E of Southern Cross, Western Australia, 7 December 1936, C.A. Gardner s.n. (holo: PERTH; iso: K, MEL). Differs from the small-flowered species of Verticordia sect. Verticordella (e.g. V. auriculata, V. centipeda) especially in the smaller leaves and the petals with the terminal fringe longer than the lamina but no lateral fringe. A shrub to 50 cm tall. Leaves 1-2 mm long, 0.5-1 mm wide, usually greyish. Peduncles 2-3.5 mm long. Hypanthium 2.2 mm long, ribbed; appendages 1-1.5 mm long. Sepals 3-4 mm long, the lamina quadrate, the basal auricles slender. Petals 4-5 mm long, including fimbriae to 3 mm long. Style 5-6 mm long, the beard hairs 0.2-0.4 mm long. Distribution and habitat. Occurs in inland areas of south-western Western Australia from Nungarin to Bungalbin, NE of Koolyanobbing, S to near the Parker Range and W towards Narembeen (Figure 34). Grows in yellow sand in shrubland. 344 Nuytsia Vol. 7, No. 3 (1991) Flowering period. November-December. Conservation status. 3R. Etymology. The specific epithet mitodes (Greek, threadlike), refers to the long fringe of the petals. Verticordia mitodes is closely related to V. auriculata and V. centipeda. It may be distinguished from those species especially by the small, usually spreading, grey-green leaves, the slender basal auricles of the sepals, and the petal fringe which is longer than the lamina. The plant usually has many erect to spreading branches forming a ± rounded shrub with pale pink flowers. The petal lamina is ± rectangular and has no lateral fringe. In two collections (GJ. Keighery 4410 and M.E. Trudgen 5524, both at PERTH), the leaves are brighter green and the flowers deep pink. Verticordia monadelpha Turcz., Bull. Soc. Imp. Naturalistes Moscou 20: 158 (1847). Holotype: south-western Western Australia, 184-, J. Drummond 3: 27 (KW; iso: BM, CGE, FI, K, MEL, NY, W). Verticordia monadelpha is widespread between Kalbarri, Eneabba and Koorda, Western Australia. Within this range it is quite variable in habit, size of floral parts, and to some extent flower colour. This variation is here formally recognised as two varieties. Key to varieties Petals 3.5-5 mm long; stamens 3-3.5 (rarely 4) mm long, the staminodes usually at least half as long; anthers 0.3 mm wide var. monadelpha Petals 3-3.5 (rarely 4) mm long; stamens 4-5 mm long, the staminodes less than half as long; anthers 0.2 mm wide., var. callitricha (Meissner) A.S. George Verticordia monadelpha Turcz. var. monadelpha Shrub to 1.5 m, somewhat openly branched or corymbose. Sepals 5-8 mm long. Petals 3.5-4 mm long, rarely to 5 mm. Stamens 3-3.5 mm long, rarely to 4 mm; anthers 0.3 mm wide. Staminodes 1/2-3/4 length of stamens. Distribution and habitat. Occurs from the Moresby Range S to Eneabba and SE through Perenjori almost to Koorda, Western Australia. Grows in deep sand and gravelly loam, in heath. Flowering period. Late October-December. Conservation status. Not rare or endangered. Typical Verticordia monadelpha var. monadelpha has bright pink flowers, sepals 7-8 mm long and petals c. 4 mm long. It occurs mainly in the eastern and south-eastern parts of the variety’s range. Western populations are more openly branched plants with pale pink flowers, sepals 5-7 mm long and petals 3.5-4 mm long. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 345 Verticordia monadelpha var. callitricha (Meissner) A.S. George, comb, et staL nov. - Verticordia callitricha Meissner, J. Proc. Linn. Soc., Bot. 1: 39 (1857). Lectotype (here chosen): south-western Western Australia, 1 850/5 1,7. Drummond 6: 48 (NY; isolecto: BM, CGE, H, K - 2 sheets, MEL, NY, W). Typification. The sheet selected as lectotype does not have Meissner’s determination but has a blue label with the collection details probably in his hand and is from his herbarium. Shrub to 70 cm, occasionally to 1.3 m, usually rounded and dense. Sepals 5-6 mm long. Petals 3-3.5 mm long, rarely to 4 mm. Stamens 4-5 mm long; anthers 0.2 mm wide. Staminodes less than half length of stamens. Distribution and habitat. Occurs from Kalbarri SE to Yuna and S almost to Morawa, Western Australia. Grows in deep sand and gravelly sand in heath and tall shrubland. Flowering period. November-January. Conservation status. Not rare or endangered. This variety is typically distinguished by the character states given above. The slightly shorter petals but longer stamens result in the latter being shortly exserted. Verticordia mueileriana E. Pritzel, Bot. Jahrb. 35: 407, fig. 48 N-S (1904). Type: between Watheroo and Coorow, Western Australia, November 1901, E. Pritzel (not found). Neotypus (here nominated): N of Marchagee, Western Australia, 5 December 1978, D. Butcher 1192 (PERTH; isoneo: B, MEL). Typification. No specimen of Pritzel’ s type collection (or indeed of the paratype Diels 519 1 , also cited by Pritzel in the protologue) has been found in the many herbaria consulted, including B. Tantalisingly, there is a label at B of the Diels collection but it is on a sheet of V. grandis, a species collected by Diels and Pritzel {Pritzel 614) and illustrated by them (op. cit. 408, fig. 48 K-M). The label must have been wrongly transposed. A neotype is therefore nominated for V. mueileriana. It agrees well with the protologue and is from a locality between Watheroo and Coorow. Within the ' chrysoslachys’ group of Verticordia sect Pennuligera, V. mueileriana is characterised by the large orbicular leaves with narrow white margin, maroon to blood red flowers, very glandular staminodes, and style with curved apex and beard of crowded long hairs (to 1 .2 mm long) surrounding the style. In its main area of distribution - between Coorow and Watheroo and a short distance westward - it is relatively consistent morphologically. In the Wicherina area, east of Geraldton, there is a variant here formally described as subsp. minor. Key to subspecies Sepals 5 mm long; petals 5 mm long including fringe to 1.5 mm long; style hairs to 1.2 mm long, crowded subsp. mueileriana Sepals 3.5 mm long; petals 4 mm long including fringe to 0.5 mm long; style hairs to 0.6 mm long, ± open subsp. minor A.S. George 346 Nuytsia Vol. 7, No. 3 (1991) Verticordia muelleriana E. Pritzel subsp. muelleriana Distribution and habitat. Occurs between Coorow and Watheroo and a short distance westward. Grows in deep sand in tall shrubland. Flowering period. Late October-December. Conservation status. 2V. Verticordia muelleriana E. Pritzel subsp. minor A.S. George Ab Verticordia muelleriana subsp. muelleriana floribus minoribus et styli barbae pilis brevior- ibus minus confertis differt Typus: Wicherina South Rd, S of Geraldton - Mullewa road, Western Australia, 10 December 1988, P. & N. Moyle 25 A & E.A. George (holo: PERTH; iso: CANS). Differs from V. muelleriana subsp. muelleriana in the smaller flowers and shorter, less crowded hairs of the beard of the style. Distribution and habitat. Known only from a small area around the type locality, where there are many plants over a distance of c. 1 km (Figure 42). Flowering period. November- December. Conservation status. 2E. Etymology. The Latin epithet minor refers to the smaller size of the flowers. The subspecies appears to hybridise frequendy with V. chrysostachys var. pallida which occurs at the same locality. Verticordia multiflora Turcz., Bull. Soc. Imp. Naturalistes Moscou 20; 159 (1847). Type: south- western Western Australia, 184-, J. Drummond 3: 26 (holo: KW; iso: BM, CGE, E, FI, K - 3 sheets, MEL, P, W). This species, at one time confused with Verticordia brachypoda Turcz. (and its synonym V. stylotricha Diels), may be distinguished from that species by its bright yellow flowers and subulate staminodes. It also resembles the yellow-flowered varieties of V. huegelii Endl. (var. stylosa and var. tridens) but is readily distinguished from them by its scarcely enlarged stigma and entire staminodes. V. multiflora has two subspecies. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 347 Key to subspecies Sepals 4-4.5 mm long; petals 2.5-3 mm long; style 3-3.5 mm long subsp. multiflora Sepals 5-6 mm long; petals 3.5-5 mm long; style 4-5.3 mm long subsp. solox A.S. George Verticordia multiOora Turcz. subsp. multiflora Shrub to 50 cm with ± straggly spreading stems. Leaves linear, semiterete, obtuse, 2-7 mm long, sessile. Hypanthium turbinate, 1.8-2 mm long, densely comose at base, the 10 ribs also hirsute. Sepals 4-4.5 mm long, deeply fimbriate. Petals 2.5-3 mm long, fimbriate. Stamens 0.6-0.8 mm long; staminodes subulate, 1 .8-2.5 mm long. Style 3-3.5 mm long, long-hirsute; stigma capitate, c. 0.5 mm diam. Distribution and habitat. Occurs in scattered localities from Darkin Swamp, NW of Brookton, S almost to the Porongurup Range, Western Australia, with an outlier SE of Lake Grace (Figure 39). Grows in clay-loam over laterite in low open woodland and heath. Flowering period. October-November. Conservation status. 3R. Verticordia multiflora Turcz. subsp. solox A.S. George, subsp. nov. Ab Verticordia multiflora subsp. multiflora floribus majoribus, et sepalorum divisionibus plus grossis, differt. Sepala 5-6 mm longa. Petala 3.5-5 mm longa. Stamina 0.8- 1.1 mm longa. Stylus 4.5-5.3 mm longus. Typus: SE of Moorine Rock, Western Australia, c. 31° 35' S, 119° 30' E, 22 October 1984, A.S. George 16447 & E.A. Berndt (holo: PERTH; iso: AD, CANB, K, MEL, NSW). Differs from V. multiflora subsp. multiflora in the larger flowers and coarser divisions of the sepals. Sepals 5-6 mm long. Petals 3.5-5 mm long. Stamens 0.8- 1.1 mm long. Style 4.5-5.3 mm long. Distribution and habitat. Occurs from SE of Merredin to Marvel Loch, Western Australia (Figure 39). Grows in pale yellow sand, gravelly sand, and sand over granite, in tall open shrubland. Flowering period. October-November. Conservation status. 2R. Etymology. From the Latin solox (shaggy, rough); the much-divided sepals give the flowers a more shaggy aspect than those of subsp. multiflora. Besides the differences in size, Verticordia multiflora subsp. solox has sepals that are divided into more numerous and coarse fimbriae. 348 Nuytsia Vol. 7, No. 3 (1991) Verticordia nitens (Lindley) Endl., Stirp. Herb. Huegel. 7 [1838] (1839) (as V. nitida) - Chrysorhoe ndeniLindley, Comp. Bot. Mag. 2: 357 (1836). Holotype: Swan River, Western Australia, 183-, - Toward s.n. (CGE). Typification. The holotype is the only collection of the species at CGE, where most of Lindley ’s types are housed. It is annotated in his hand. This is the correct author citation for this species whose combination has often been wrongly attributed to Schauer, who made the same combination in 1841. Verticordia nobilis Meissner, J. Linn. Soc., Bot. 1; 39 (1856). Type: near Smith R., Western Australia, 1850-51, J. Drummond 6: 47 (holo: NY; iso: BM, CGE, FI, K-2 sheets, LD, NSW, P-3 sheets, W). This species is here reinstated, the name having been placed in synonymy under V. grandiflora Endl. since Bentham (1867). It may be distinguished from that species especially by the larger flowers on longer peduncles, by the larger, erect stamens and the longer exserted style. The leaves are usually longer and the upper ones usually not on short lateral branchlets as are those of V. grandiflora. Verticordia nobilis grows to the north of Perth from Gingin to Kalbarri, whereas V. grandiflora is to the east and south east. Verticordia oculata Meissner, J. Linn. Soc., Bot. 1: 41 (1856). Lectotype (here chosen): between Hutt River and Murchison River, Western Australia, 1850/51, J. Drummond 6: 43 (NY; isolecto: BM, CGE - 2 sheets, FI, K - 3 sheets, LD, NSW, W). Typification. For most of Meissner’s species of Verticordia there are types at NY, annotated by him, that can be taken as holotypes. This is not the case with V. oculata, for which the NY sheet bears a label in his hand but without determination. Since he saw the specimen, however, it is here selected as lectotype. Verticordia ovalifolia Meissner, J. Linn. Soc., Bot. 1: 40 (1856). Lectotype (here chosen): south- western Western Australia, 19,50151, J. Drummond 6: 45 (NY; isolecto: CGE, K-2 sheets, LD,W). Typification. As with V. oculata, the sheet at NY bears a label with the details in Meissner’s hand but not determined by him. Verticordia oxylepis Turcz., Bull. Cl. Phys.-Math. Acad. Imp. Sci.

The type sheet of V. oxylepis at K W, annotated by T urczaninow , bears three specimens, all of the same taxon but from different plants and possibly localities. That selected as lectotype is the most mature plant and has Drummond ’s number tag attached. A second has two burnt stem bases with a regrowth shoot in flower, while the third is similar to this but without the burnt stems. The sheets at K have specimens of each collection. The specimen selected as lectotype for V. demissa corresponds morphologically with the lectotype of V. oxylepis. Verticordia paludosa A.S. George, sp. nov. Inter species Verticordiae sect. Verticordellae ad V. bifimbriatam arete affmis, a qua foliis floralibus latioribus ciliatis, bracteolis ciliatis, floribus pallide roseis, appendicibus reflexis in hypanthium transientibus, sepalis 6-7-lobatis non auriculatis, petalis parce brevioribus, staminibus staminodiisque brevioribus et breviter unitis, stylo parce breviore, et florescentia serotina, differt. Typus: Red Gully Road, adjacent to Moore River National Park, Western Australia, c. 3 1° 05' S, 1 15° 45' E, 11 January 1973, MT. Burbidge 8061 (holo: PERTH; iso: CANB, K, MEL). Figure 26. Closely related to V. bifimbriata from which it differs in the broader ciliate floral leaves, ciliate bracteoles, pale pink flowers, the reflexed appendages of the hypanthium merging into the hypanthium, the 6-7-lobed non-auriculate sepals, the slightly shorter petals, the shorter stamens and staminodes, the slightly shorter style, and the later flowering period. Distribution and habitat. Restricted to an area between Mogumber, Gillingarra, Regans Ford and the S end of Moore River National Park, Western Australia (Figure 37). Grows in sandin shrubland and low open woodland, usually on winter- wet flats. Flowering period. January-May. Conservation status. 2V. The few collections are from an area being increasingly cleared. Etymology. The specific epithet {Lalin, paludosus), refers to the habitat. A distinctive feature of this species is the reflexed appendages which merge into the hypanthium, in contrast to the semi-detached form in other taxa of Verticordia sect. Verticordella. The shortly ciliate bracteoles are also unique in the section. The petals are usually bifimbriate. One collection (Gillingarra, A. Popplewell, PERTH) has the leaves more crowded and narrower than typical plants. Another (Boonanarring Brook, 20 March 1986, J.J. Alford 399 (PERTH) has the petal fringe mostly simple.

The three collections on the type sheet of V. setigera all represent the same taxon as V. pennigera. Drummond’s specimen is the best of the three. Verticordia picta Endl., Stirp. Herb. Huegel 3: 6 [1838] (1839). Lectotype (here chosen): south- western Western Australia, 183-, J.S. Roe (W). Syntype: same locality and collector (BM, W). Verticordia pentandra Turcz., Bull. Soc. Imp. Naturalistes Moscou 20, 1: 157 (1847). Type: south- western Western Australia, J. Gilbert 329 (holo: KW). Typification. The type sheet of V. picta at W is annotated ‘N. H. a. O. (Roe n. 3.)’, i.e. Novae Hollandiae australis Occidentalis, and has two specimens labelled 5 and 23 , although Roe apparently did not use collection numbers. Because the specimens appear to be from different plants (and possibly localities), one is selected as lectotype, being that associated with the number 23 . The flower has 5 fertile stamens, Endlicher having erred in implying in the protologue that there were 10. Turczaninow, in the protologue of V. pentandra, described the staminal filaments as ciliolate, but they are in fact glabrous. He may have mistaken the style beard as staminal hairs. Verticordia pityrhops A.S. George, sp. nov. Ad Verticordiam harveyi Benth. affinis, a qua habitu piniformi, foliis confertis, et floribus minoribus, differt.

Typus: East Mt Barren, [Fitzgerald River National Park], Western Australia, 33° 55' S, 120° 02' E, 17 March 1972, A.5. George 11296 (holo: PERTH; iso: CANB, K, MEL, NSW). Figure 27. Related to V. harveyi, from which it differs in the pine-like habit, crowded leaves and smaller flowers. Leaves 7-14 mm long. Hypanthium 2 mm long. Sepals and petals 2 mm long. Stamens 1 mm long. Style 5 mm long. Distribution and habitat. Known only from East Mt Barren, Fitzgerald River National Park, Western Australia, where it occurs on the platform c. 100 m above sea level (Figure 34). Grows in white sand among quartzite rocks, in open heath. Flowering period. February- June. Conservation status. 2VC. Although in a National Park, the only known population is small and is divided by a recently-built road. Etymology. From the Greek pitys (a pine) and rhops (a shrub), in reference to the small pine-like habit. Related to V. harveyi but distinct especially in the small dense habit, long crowded leaves and small flowers. 352 Nuytsia Vol. 7, No. 3 (1991) Figure 27. Holotype of Verticordia pityrhops.

Leschenault (FI; isolecto; BM, FI, P). Typification. The lectotype specimen is one of four on a sheet at FI. The sheet is labelled ‘ ‘Camelaucium [sic] plumosum Mem. du mus. ” in a shaky hand, probably that of Desfontaines. The lectotype strongly resembles Desfontaines’ plate of Chamelaucium plumosum. The isolectotype sheet at FI is from Labillardiere’s herbarium and bears the locality ‘ ‘Port du Roi Georges” , i.e. King George Sound. The specimens at BM and P have the same locality, the BM sheet also having the date 1803. As here circumscribed, V. plumosa is the most variable species of the genus. Seven varieties are recognised, but there are intermediate specimens linking most of these. The complex would be an excellent subject for a post-graduate study. The varieties are distinguished by combinations of character-states in respect of habit, leaf form, peduncle form, flower size and colour, indumentum of hypanthium, sepal lobes and habitat. Leaf width and thickness are measured at the widest point. Key to varieties la Sepals 4-5 mm long; petals 3. 5-4.5 mm long; sepals and petals white, rarely mauve var. grandiflora (Benth.) A.S.

Sepals 3-3.5 mm long; lobes broad, shortly fimbriate in upper part. Petals 3.5-3.8 mm long. Distribution and habitat. Occurs in south-western Western Australia near the S coast from Windy Harbour to Albany, along and E of the Darling Scarp between Red Hill and Jarrahdale, and at scattered localities between these areas, e.g. Mt William, Boyanup. Grows on granitic slopes, in heath. Flowering period. August-December. In typical Verticordia plumosa var. plumosa the groups of flowers are small and borne on many of the short lateral branchlets. Darling Range populations have larger, more rounded groups of flowers mostly at the main branch apices. Collections intermediate in form include Helena River, October 1919, C.S. Bardwell-Clarke (PERTH); Mt Chudalup, 30 October 1972, GJ. Keighery 1369 (PERTH); and The Gap, Albany, 15 August 195 1,^.D. Royce 3738a (PERTH). Several collections, from widely dispersed localities, have narrow sepal lobes, e.g. Mt Chudalup,19 January 1966, F. Lullfitz 4709 (PERTH); Mundaring, 10 July 1979, R. Cranfield 878 (PERTH).

Disdnguished among the other variedes of Verticordia plumosa especially by the small flowers, narrow lobes of the sepals and narrow petals. Closely related to var. vassensis but differs in the more numerous groups of flowers on short lateral branchlets, the narrower sepal lobes and the narrow petals A.S.

Sepals 23-2.5 mm long. Petals 2-2.4 mm long. Distribution and habitat. Restricted to a small area to the west and south west of Mundijong, south east of Perth, Western Australia (Figure 43). Grows on clay and sandy-loam flats in low shrubland. Flowering period. October-November. Conservation status. 2E. Known from only a few small populations on road verges in a heavily cleared area. Etymology. Varietal name from the Greek pleio- (more than usual) and botrys (a bunch), in reference to the many small lateral groups of flowers. Verticordia plumosa var. ananeotes A.S. George, var. nov. Inter varietates alias Verticordiae plumosae turma characterorum sequenti distinguitur: frutex lignotubere caulibus pluribus ad 40 cm aids; foliis 6-14 mm longis, 0.4-0.7 mm latis; pedunculis 4- 7 mm longis; hypanthio 1.5 mm longo; sepalis 3-3.5 mm longis, lobis 3 vel 4 breviter dentatis. Typus: Molloy’s Plains, Sussex District, Western Australia, 17 December 1839, L. Preiss 174 (holo: LD; iso: BM, NY, W). Shrub with small lignotuber and several to many simple or sparsely branched stems to 40 cm. Leaves sparsely arranged on main stems but crowded on short axillary branchlets, 6- 14 mm long, 0.4- 0.7 mm wide, abruptly acute. Flowers in small groups. Peduncles 4-7 mm long. Hypanthium 1.5 mm long, stiffly hirsute. Sepals 3-3.5 mm long; main lobes 3 or 4, very shortly and irregularly lobed towards apex. Distribution and habitat. Recorded at Serpentine, “Murray District” (i.e. between Mundijong and Waroona), Blackwood River, and Vasse River and “Molloy’s Plains, Sussex District”, i.e. near Busselton, Western Australia (Figure 39). Grows in sandy soil in open Jarrah woodland (Murray District) and on a sandy plain (Molloy’s Plains). Flowering period. November-December. Conservation status. Unknown. Collected six times between 1839 and 1900, but not since. Etymology. Named from the Greek ana- (again) and neos (new, recent), in reference to the plant’s ability to resprout after fire from its small woody stock. This variety is easily recognised by its distinctive habit. The specimens appear to be parts of plants, hence the habit is probably densely tufted. The simple stems, long intemodes and long slender leaves are also distinctive. 356 Nuytsia Vol. 7. No. 3 (1991) Verticordia plumosa var. vassensis A.S. George, var. nov.

Occurs in far south-western Western Australia from Ambergate to Ruabon and Tutunup (Figure 37). Grows on winter-wet sandy flats. Flowering period. October- January. Conservation status. 2E. Endangered since all known plants are on road and railway verges in a well- cleared area. Etymology. Named for the Vasse district in which the variety occurs, with the suffix -ensis (relating to). Differs from other varieties in the short peduncles and small flowers. Several collections are intermediate morphologically between Verticordia plumosa var. vassensis and var. brachyphylla. These include Darkin Swamp, 12 November 1981 , A. Selkirk 1 1 (PERTH), and S of Bowelling, 29 September 1 985, V. Crowley 1 (PERTH), which have pedicels 3-6 mm long and sepals c. 2 mm long. A collection from Corbalup Road near Manjimup, December 1985, A.Annels 1, (PERTH), appears intermediate between var. vassensis and var. plumosa. It contains 2 specimens, one with sepals c. 2 mm long, the other 3 mm. The leaves are mostly 3-5 mm long, only slightly thickened, and the peduncles are up to 12 mm long. A similar collection is from Three Chain Road, Scott River, October 1980, E. Russell (PERTH); it has long peduncles but sepals 2 mm long. Verticordia plumosa var. brachyphylla (Diels) A.S.

George, Verticordia (Myrtaceae: Chamelaucieae) 357 Domin cited in synonymy V.fontanesii var. brevifolia F. Muell., Fragm. 10: 28 (1876). The phrase ‘ ‘ varietatem brevifoliam ’ ’ there used by Mueller appears, however, to be a mention of a short- leaved variety rather than a formally proposed name. On the same page he used a similar form of expression under V. brownii, V. chrysantha and V. chrysostachys. Shrub to 70 cm, sometimes taller, without lignotuber, openly branched. Leaves 2-6 mm long, 0.5- 0.6 mm wide, slightly thickened upwards. Peduncles 7-11 mm long. Sepals and petals pink. Hypanthium 2 mm long. Sepals 2. 5-3. 5 mm long; lobes narrow to moderately broad, plumose ± to apex. Petals 2.2-3 mm long. Distribution and habitat. Widespread from Badgingarra S to Pinjarra, inland to Tammin and S through the Great Southern to Mt Barker, Western Australia (Figure 44). Grows in sand in low-lying, often seasonally damp, heath and open woodland. Flowering period. October-December. Conservation status. Not rare or endangered. Plants of the coastal plain generally have longer, more slender leaves and peduncles than those of northern and inland localities. Verticordia plumosa var. incrassata A.S. George, var. nov.

George 10473 (holo: PERTH; iso: CANB). Shrub without lignotuber, with several irregular spreading stems, to 80 cm tall; intemodes of main stems short; lateral branchlets many. Leaves crowded, thickened upwards, obtuse, 1.5-5 mm long, 0.5-1 mm thick, deep green. Peduncles usually 3-8 mm long, thickened upwards. Hypanthium 1.4- 1.5 mm long, long-hirsute. Sepals 3-4 mm long; main lobes 5-7,erose to almost entire towards apex. Petals 2.5-3 mm long. Distribution and habitat. Occurs in the Fitzgerald River National Park from Point Charles and Mt Bland E almost to the Hamersley River, N toward Newdegate and NE to Forrestania and Scaddan, Western Australia (Figure 37). Grows in gravelly clay and sandy loam, in low heath. Flowering period. Mainly August-November. Conservation status. Not rare or endangered. Etymology. Named from the Latin incrassatus (thickened), in reference to the leaves and pedicels. 358 Nuytsia Vol. 7, No. 3 (1991) A variable taxon that should be studied further. Plants in the Fitzgerald River National Park are more straggling and spreading than those to the NE. The latter have short, very thick leaves. Differs from Verticordia plumosa var. grandiflora in the straggling habit, thicker leaves, smaller hypanthium and smaller pink flowers. From Scaddan southwards the variety grades into var. grandiflora, the leaves becoming more slender, the peduncles longer, e.g. Truslove, October 1944, G.E. Brockway 12 (PERTH). Some collections from the Fitzgerald River National Park show a tendency towards var. brachyphylla, e.g. 31 October 1985, A.S. George 7089 (PERTH) which has peduncles to 10 mm long. Verticordia plumosa var. grandiflora (Benth.) A.S. George,comb. nov. Verticordia fontanesii DC. vai. grandiflora Benth., FI. Austral. 3: 21 (1867). Holotype: south-western Western Australia, 184-, J.

Lectotype (here chosen): south-western Western Australia, 184-,/. Drummond 5: 1 10 (KW; iso: BM, CGE, E, FI, K - 2 sheets, NSW, PERTH, W). Typification. The holotype sheet of V. plumosa var. grandiflora is annotated “var. grandiflora” in Bentham’s hand. At KW, where Turczaninow’s other types of Verticordia are housed, there is a single sheet with three specimens of V. pectinata (all from the same gathering). The specimens agree with the protologue, but since the sheet was not annotated by Turczaninow it is here selected as lectotype. Shrub without lignotuber and 1 or few erect stems, sparsely branched, to 1.3 m tall. Intemodes of main branches mostly 10-15 mm apart. Leaves slightly thickened upwards, obtuse, 2-7 mm long, 0.5-0.8 mm wide, medium green. Flowers in rounded groups, ± crowded. Peduncles 5-10 mm long. Hypanthium 2-2.2 mm long, stiffly hirsute. Sepals and petals white or pale pink. Sepals 4-5.5 mm long; main lobes 5 or 6, plumose becoming erose at apex. Petals 3.5-4.5 mm long. Distribution and habitat. Occurs near the S coast of Western Australia from near the E end of the Porongurup Range to Mt Baring, E of Esperance (Figure 44). Grows in deep sand in heath, often in low-lying places. Flowering period. September-December. Conservation status. Not rare or endangered. Typically distinguished by the white flowers that are larger than those of the other varieties. There is some variation in flower size, sometimes within a population, e.g. near Mt Merivale, 9 November 1985, A.S. George 16607 (PERTH) in which sepal length ranges from 3.2-4 mm. A collection from near Mt Maxwell, 6 November 1 985, A .S. George 16587 (PERTH) has smaller flowers than usual and this population included plants with pale pink flowers. A variant of V. plumosa occurring in the Cape Riche area, represented by A.S. George 16500 (PERTH), is intermediate between var. grandiflora and var. plumosa. The plants are compact in habit, have thick leaves 3-7 mm long, peduncles 4-6 mm long, sepals 3.8 mm long and petals 3.3-3.6 mm long.The petals and androecium are very hairy towards the base. A.S.

Figure 28. Related to V. mitchelliana, from which it differs in being altogether smaller except the androecium, and in the warty leaves and branchlets, the horizontal flowers, and the stamens and staminodes united for most of their length. Leaves semiterete, 2-7 mm long. Peduncles 7-9 mm long. Hypanthium 2-2.5 mm long, hirsute towards base. Sepals 5-6 mm long. Petals 3-4 mm long, fimbriate. Stamens 2.6-3.5 mm long; staminodes 3-3.5 mm long. Style 13-15 mm long. Distribution and habitat. Recorded from several localities in the Mt Hampton area, NE of Narembeen, Western Australia (Figure 36). Grows in sandy loam over granite, in open and tall shrubland. Flowering period. October-December. Conservation status. 2RC. Etymology. From the Latin pulchellus (pretty), in reference to the attractive appearance of the plant. Verticordia pulcheila is a distinctive species, related to V. mitchelliana but smaller in all respects except the length of the stamens and staminodes. It is a small shrub with spreading or arching 360 Nuytsia Vol. 7, No. 3 (1991) Figure 28. Holotype of Verticordia pulchella. Scale in cm. A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 361 branches, sometimes in layers. The sepals are red with a green base. The petals are usually deep pink but vary to pale pink and yellow. The style is red. Both branchlets and leaves are somewhat warty, the branchlets with whitish warts, the leaves with raised oil glands. Verticordia roei Endl., Stirp. Herb. Huegel. 3: 6 [1838] (1939). Type: south-western Western Australia, 183-,/.S. Roe (holo: W; iso: BM). Typical V. roei is widespread and locally frequent in the south-eastern agricultural region of Western Australia. It is a relatively consistent taxon, varying a little in the length of the stamens and staminodes and in width of the staminodes. Several scattered populations to the north of typical V. roei are somewhat distinct and are worth recognising as a subspecies. Key to subspecies Stamens 3-3.8 mm long; staminodes usually 0.2-0.4 mm wide at base, ± acute; style 2.2-3 mm long subsp. roei Stamens 1. 8-2.5 mm long; staminodes 0.5 mm wide at base, obtuse; style 1.4-1.9 mm long subsp. meiogona A.S. George Verticordia roei Endl. subsp. roei Corymbose shrub to 1 m, related to V. insignis and V. inclusa but distinguished especially by the all-cream flowers, long stamens and simple or shortly lobed staminodes. Stamens 3-3.8 mm long; staminodes 0.2-0.4 mm wide at base. Style 2.2-3 mm long; stigma broadly capitate. Distribution and habitat. Widespread in inland south-western Western Australia, from Southern Cross to Dumbleyung and Peak Charles (Figure 43); grows in sand, sandy loam over gravel, and clay- loam, in heath. Flowering period. October-November. Conservation status. Not rare or endangered. Verticordia roei subsp. meiogona A.S. George, subsp. nov. Ab Verticordia roei Endl. subsp. roei staminibus brevioribus (1. 8-2.5 mm longis), staminodiis latioribus (ad basin 0.5 mm latis), et stylo breviore (1.4-1.9 mm longo), differt. Typus: Clark Road, N of Bonnie Rock-Burakin road. Western Australia, 30° 16' S, 118° 04' E, 21 October 1984, A.S. George 16429 & EA. Berndt (holo: PERTH; iso: CANB, K, MEL, NSW). 362 Nuytsia Vol. 7, No. 3 (1991) Differs from V. roei subsp. roei in the shorter stamens (1. 8-2.5 mm long), broader staminodes (0.5 mm wide towards base) and shorter style (1.4- 1.9 mm long). Distribution and habitat. Recorded only from the type locality, a nearby locality and near Dalwallinu, Western Australia (Figure 36). Grows in sandy loam with some gravel, in low heath. Flowering period. September-October. Conservation status. 2E. The subspecies is endangered, occurring only on road verges in an area developed for agriculture. Etymology. Named from the Greek meio- (meiouros) (smaller) and -gone (gonimos) (fruitful, having generative power), in reference to the shorter stamens and style of the subspecies. The subspecies is distinguished from typical V. roei by the shorter stamens and style, and by the broader staminodes that are entire or 1-lobed each side. The flowers are sometimes pink. The subspecies has possibly arisen through hybridisation between typical V. roei and V. inclusa, although neither species occurs in the area. A single plant among a population of V. inclusa SE of Newdegate, 1 1 October 198 1 , £. Berndt 32, (PERTH) is similar to V. roei subsp. meiogona but has shorter stamens and style and acute staminodes. The ranges of V. roei subsp. roei and V. inclusa overlap widely. Given the strong winds often experienced in south-western Western Australia, it is feasible for the fruit to have been transported over the distances to the localities where subsp. meiogona occurs.

Berndt (holo: PERTH; iso: CANB, K, MEL). Closely related to V. grandiflora and V. nobilis, from both of which it differs in the smaller flowers, smaller staminodes, more fringed staminodes and shorter style. Sepals4.5-5 mm long. Petals 4 mm long. Stamens 0.5-1 mm long. Style 0.2 mm long. Distribution and habitat. Occurs from the Mt Lesueur area ME to Alexander Morrison National Park and SE to Koonah Road, SSE of Badgingarra, Western Australia (Figure 41). Grows in sand over laterite or sandstone, in heath and open mallee-heath. Flowering period. October-mid November. Conservation status. 2RC. Etymology. Named from the Latin rutilus (red with a metallic lustre) and aster (a star), in reference to the appearance of the flower as it ages and turns red; the petals change first and together appear star-like. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 363 The species is related to V. grandiflora and V. nobilis in having a bifurcate anther appendage but can be distinguished by its smaller flowers, short stamens and staminodes (the latter fimbriate with more cilia than in the other two species), and the very short style. After anthesis the staminodes usually curve inward over the stamens. Verticordia serotina A.S. George, sp. nov. Ad Verticordiamforrestii F.

Closely related to V.forrestii, from which it differs in the larger leaves and flowers and the later flowering period. Leaves 4-6 mm long. Hypanthium 5 mm long. Sepals 8-9 mm long, 13-14 mm wide. Petals 6 mm long, 4-5 mm wide. Stamens 3-3.5 mm long. Style 8 mm long. Distribution and habitat. Occurs in the southern part of the Cape Range, Cape Range National Park, north-western Western Australia (Figure 46). Grows on red sand dunes in open shrubland. Flowering period. September. Conservation status. 2RC. Etymology. Named from the Latin serotinus (late), in reference to the flowering period being later than that of the closely related V.forrestii. This species is clearly related to V. forrestii which is widespread in north-western Western Australia. V. serotina has larger leaves and flowers, the latter being a deeper pink than those of V. forrestii. Both species were present on the same dune at the type locality; V.forrestii had almost finished flowering, but V. serotina was just beginning. Verticordia serrata (Lindley) Schauer, November Act.

Since there is only one collection on the sheet at CGE annotated by Lindley it is taken as the holotype. The locality Swan River, cited for many collections at that period, indicates only the south-western comer of Western Australia. V. serrata is a variable species, and the form represented by the type occurs in southern inland districts. Bentham (1867) recognised the variation in V. serrata but stopped short of formal names, citing the collections seen under four forms, a-d. Two of these, a and d, are here placed in typical V. serrata. In the present treatment three varieties are recognised, two described as new. 364 Nuytsia Vol. 7, No. 3 (1991) Key to varieties la Stem leaves linear, acute var. linearis A.S.

Grows in sand and sandy loam in heath and mallee heath. Flowering period. October-November. Conservation status. Not rare or endangered. Verticordia serrata var. serrata usually has smaller leaves and flowers than the two other varieties. It varies considerably in the morphology of all parts. Typically the stem and floral leaves are obovate, 2.5-3 mm long, with cilia to 0.3 mm long. The lowest peduncles are c. 9 mm long. The sepals are 3 mm long; petals 2.5-3 mm long and c. 1 .5 mm wide with teeth to 1 mm long. The stamens are 4 mm long, the anther 0.3 mm long with an appendage 0.2 mm long. Notable variants are: 29 km S of Ongerup, 2 November 1982, N. Stevens 20, and 16 km S of Boddington, 8 September 1980,£).

Differs from V. serrata var. serrata especially in the longer (0.5-2 mm) cilia of the leaves, longer peduncles (the lowest 12-18 mm long) and the more prominent reflexed fimbriae of the sepals. A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 365 Distribution and habitat. Widespread in south-western Western Australia from near Camamah to York and E to Cadoux and Tammin; also recorded N of Bendering (Figure 45). Grows in sand and gravelly sand, in heath and open woodland. Flowering period. Late September-late November. Conservation status. Not rare or endangered. Etymology. Named from the Latin ciliatus (ciliate), in reference to the prominent cilia of the leaf margins. This is Bentham’s form c. (FI. Austral. 3: 23). The longer leaf cilia, peduncles, stamens and style usually distinguish it from var. serrata. In the central wheatbelt there is some intergradation, e.g. W of Koonadgin Siding, 16 November 1983, M. Smith 92 (PERTH). Verlicordia serrata (Lindley) Schauer var. linearis A.S. George, var. nov. Ab varietatibus aliis Verticordiae serratae foliis linearibus acuminatis praecipue differt.

Differs from the other varieties of V. serrata especially in the linear acuminate leaves. Leaves 6- 20 mm long, with marginal cilia to 1 .2 mm long often only in the lower half. Lowest peduncles c. 12 mm long. Distribution and habitat. Occurs c. 55-60 km N of Perth in the Muchea district. Western Australia (Figure 45). Grows in gravelly sand, in eucalypt open woodland. Flowering period. Late September-October. Conservation status. 2E. Etymology. Named from the Latin linearis (linear), in reference to the leaves. This is Bentham’s form b (loc. cit.). Several collections from the Bindoon-Toodyay area to the north are intermediate between var. linearis and var. ciliata. e.g. between Toodyay and Bindoon, 2 Oct. 1947, C.A. Gardner s.n. (PERTH). Verticordia sieberi Diesing ex Schauer, Nov. Act. Cur. 19: suppl. 2: 201 (1841). Typification. The holotype of this name is a sheet at W labelled King George Sound with the annotation by Schauer: “[Diesing msc.J Nomen recepi, sed haec species a DC. quantum scio 366 Nuytsia Vol. 7, No. 3 (1991) nusquam est descripla’ i.e. “ [Diesing in manuscript] I received the name but as far as I know this species has nowhere been described by de Candolle”. The locality appears an error, since the type represents the variant tliat occurs from Esperance to Cape Arid. The collector is unknown but may have been Robert Brown. Franz Sieber, after whom the species is named, did not visit south-western Australia. Verticordia sieberi is distinguished from V.plumosa especially by the narrow midribs and deeper fringing of the sepal lobes, and from V. stenopetala by the shorter, usually orbicular petals and shorter style. These three species are very closely related. Verticordia sieberi shows considerable variation, here recognised as four varieties, but further study is needed.

Flowering period. Mainly January-April. A.S. George, Verlicordia (Myrtaceae: Chamelaucieae) 367 Conservation status. Not rare or endangered. Etymology. Named from the Greek loma (a fringe or border), in reference to the petal margin. The variety is distinguished from typical V. sieberi by the shortly fimbriate petal margin. The feature is consistent in most collections from Munglinup westwards. In some western populations the plants are very slender. Verticordia sieberi Diesing ex Schauer var. pachyphylla A.S.

Differs from the other varieties of V. sieberi in the broader thick leaves (1.5-2 mm wide) and the shorter style (4 mm long). Petals fimbriate. Distribution and habitat. Known only from the type (Figure 45). Described as ‘frequent in patches in Darwinia diosmoides low shrubland. Well-drained, slightly saline, aeolian loamy sand . . inner slope of salt lake.’ Flowering period. In full flower in January. Conservation status. 1 VC. The variety probably occurs around other salt lakes in the region. Etymology. The varietal epithet is derived from the Greek pachys (thick) and phyllon (a leaf), in reference to the very broad, thick leaves. The very broad, thick leaves distinguish Verticordia sieberi var. pachyphylla from var. sieberi and var. lomata. The peduncles are also very thick and 1-3 mm long, shorter than those in most collections of the other varieties. The sepals are 2.8-3 mm long. The flowers are very pale pink fading to white.

Grows in and over laterite, in heath with open mallee eucalypts. Flowering period. December-February. Conservation status. 2R. Etymology. Named from the Latin curtus (short), in reference to the sepals. The small hypanthium and short sepals result in the petals dominating the flower. VerticordiaspicataF. Muell., Fragm. 1:226(1859). Lectotype (here chosen): towards Murchison River, Western Australia, 18—, A. Oldfield s.n. (K; isolecto: BM). Typification. No sheet of this collection has been found at MEL, where most of Mueller’s types are housed. Verticordia spicata is characterised in Verticordia sect. Verticordella by the small closely imbricate ovate-elliptic leaves with prominent oil glands and narrow ciliate margins, crowded sessile or almost sessile flowers, a honeycombed obscurely ribbed hypanthium, sepals 3-5.5 mm long with slender auricles, petals 2-5 mm long with scabrid fringe 1-2 mm long, and a slender straight exserted style 4-9 mm long with a beard 1-1.5 mm long of hairs 0.3-0.4 mm long. The reflexed appendages are usually almost as long as the hypanthium. Typical V. spicata occurs in Kalbarri National Park, extending N towards Cooloomia and SE towards Northampton and Yuna (Figure 41). There is one record near Mullewa. The subspecies is somewhat variable in size and flower colour. A second subspecies occurs between Arrino and Morawa, distinguished by its smaller leaves and flowers. Key to subspecies Style 6.5-9 mm long; sepals 5-5.5 mm long; petals 4-4.5 mm long, the lamina 2 mm wide; leaves mostly 2-3.5 mm long subsp. spicata Style 4 mm long; sepals 3-4 mm long; petals 3 mm long, the lamina 1.5 mm wide; leaves mostly 1.5-2 mm long subsp. squamosa A.S.

George, Verticordia (Myrtaceae: Chamelaucieae) 369 Typus: E of Three Springs-Morawa road along Simpson Road, Western Australia, c. 29° 24' S, 1 15° 50' E, 30 December 1981, C. Chapman 42 (holo: PERTH; iso: CANB, K). Figure 29. Differs from V. spicata subsp. spicata in the smaller leaves and flowers. Leaves usually 1.5-2 mm long, erose to shortly ciliate. Sepals 3.5 mm long. Petals 2.5 mm long. Style 4 mm long. Distribution and habitat. Known from six collections, one without locality, the others from the area between Three Springs and Morawa, Western Australia (Figure 41). Grows in deep yellow sand, in tall shrubland. Flowering period. November-December. Conservation status. 2E. The subspecies is recorded only from road verges in a heavily cleared area. Etymology. The subspecific epithet (Latin, squamosus, scaly), refers to the small appressed, imbricate leaves. At the type locality, Verticordia spicata subsp. squamosa grows with V. comosa and appears to hybridise with that species. A representative collection of a presumed hybrid is Chapman 58A (PERTH) which has somewhat spreading leaves mostly 2-3 mm long with prominent oil glands, a honeycombed hypanthium with reflexed appendages c. half as long, sepals 3.5 mm long with prominent (but not peltate) auricles, stiffly fringed sepal lobes, petals 3 mm long with small auricles, and a style 5 mm long with a more dense beard than subsp. squamosa. The staminodes are slightly flattened and obscurely lobed below the apex. Chapman 47 (PERTH) has almost appressed leaves, similar flowers but with larger sepal auricles and the style beard of crowded hairs to 0.5 mm long; the flowers were described as “off-white”.

Staminodia c. 1 mm longa, obtusa. Typus: nearPingaring,Westem Australia, 32°45'S, 118° 39' E, 23 October 1984, A.S. George 16464 & E.A. Berndt (holo: PERTH; iso: AD, CANS, K, MEL, NSW). Differs from V. staminosa subsp. staminosa in the smaller flowers, the longer staminal tube, and the staminodes inserted between the staminal fdaments. Sepals 5-6 mm long. Stamens 6-7 mm long. Staminodes c. 1 mm long, obtuse. Distribution and habitat. Occurs on granitic hills from Pingaring to E of Newdegate, Western Australia. The smaller flowers, shorter stamens but united for half their length, and the staminode insertion between the stamens, distinguish this subspecies from subsp. staminosa. Etymology. From the Latin cylindraceus (cylindrical), in reference to the androecium. There are two varieties distinguished by their habit. Verticordia staminosa subsp. cylindracea A.S. George var. cylindracea Shrub with widely spreading branches. Distribution and habitat. Occurs on several granitic outcrops from Pingaring to E of Newdegate, Western Austraha (Figure 36). 372 Nuytsia Vol. 7, No. 3 (1991) Flowering period. July-October. Conservation status. 2R. Verticordia staminosa subsp. cylindracea var. erecta A.S. George, var. nov. Ab Verticordia staminosa var. cylindracea habitu erecto ad 1 m alto differt.

Differs from V. staminosa var. cylindracea in the erect habit (to 1 m tall). Distribution and habitat. Recorded only from the type locality which is on a farm (Figure 36). Grows in coarse soil on a granitic hill, with Borya. Flowering period. July-October. Conservation status. 2E. The population is on freehold land and is protected by the owners. Etymology. Named from the Latin erectus, in reference to the habit. The erect, pine- like growth, consistent in the population, distinguishes this from V. staminosa var. cylindracea, with which it shares the same floral characters that separate the subspecies from subsp. staminosa. Verticordia stenopetala Diels, Bot. Jahrb. Syst. 35: 402 (1904). Type: near Bronti, Coolgardie District, Western Australia, November 1901, E. Diels 6105; not found. Neotype (here nominated): SEof MoorineRock, Western Australia, 3 1“ 26' S, 1 19“ 15' E, 22 October 1984, A.5. George 16438 & E.A. Berndt (PERTH; isoneo: B, CANB, K, MEL). Typification. No specimen of Diels’ collection has been found among the material of Verticordia in some 20 herbaria, including the Botanisches Museum Berlin-Dahlem (B) where his main set was lodged. The type is therefore presumed lost and the above neotype is here nominated. The neotype agrees well with the protologue except that the petals are c. 3.5 mm long and 1.5-2 mm wide. The length of the peduncle was given as 6 cm by Diels, an error for 6 mm. Verticordia subulata A.S. George, sp. nov. Ad Verticordiam acerosam Lindley affinis, a qua sepalis densiore fimbriatis, staminodiis teretibus subulatis et stylo brevi (0.5-1 mm longo), praecipue differt.

A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 373 Closely related to V. acerosa, from which it differs especially in the more densely fimbriate sepals, the terete subulate staminodes and the short style (0.5-0.7 mm long). Distribution and habitat. Occurs from the Cranbrook-Tambellup area SE through the Stirling Range to South Stirling and Wellstead, Western Australia (Figure 36). Grows in clay and sandy loam, sometimes over laterite, in eucalypt woodland and mallee shrubland. Flowering period. September-October. Conservation status. Not rare or endangered. Etymology. Named firom the Latin subulatus (narrow with a fine point), in reference to the staminodes. Verticordia subulata is related to V. acerosa and less closely to V. endlicheriana, being distinguished especially by the subulate staminodes and short style. The floral leaves are usually very broad and the sepals more densely fimbriate than in V. acerosa and V. endlicheriana. The flowers have no scent, while those of V. acerosa and V. endlicheriana have a typical Verticordia scent; they turn deep red with age. Some collections, mainly from the eastern parts of the species’ range, have staminodes with a small lobe on one or both sides. Verticordia tumida A.S. George, sp. nov. Ab speciebus aliis Verticordiae sect. Verticordellae hypanthio latiore, appendiculis tumidis, stylo breviore et ovulis plus numerosis, praecipue differt.

Stylus 3.5-4 mm longus, ad apicem curvatus; pili barbae 0.6-0.8 mm longi. Ovuli 8-10. Typus: Tammin, Western Australia, 26 November 1953, C.A. Gardner 12108 (holo: PERTH; iso: CANB, PERTH). Differs from the other species of Verticordia sect. Verticordella especially in the broader hypanthium with swollen reflexed appendages, the shorter style and the more numerous ovules. Leaves elliptic, obovate or oblong, thick, obtuse but shortly mucronate, 1-3 mm long, ± spreading, grey-green. Flower groups small. Peduncles 2-3 mm long. Hypanthium 2.5-3.5 mm long, 2.5-4 mm wide, rounded-ribbed; reflexed appendages thickened, 1-1.8 mm long, obtuse. Sepals 5-6 mm long, with 5-10 lobes, ± auriculate with reflexed cilia. Petals 5-5.5 mm long; fimbriae 1. 8-2.5 mm long, coarsely serrate or entire, scabrid. Stamens 2.1-3 mm long; staminodes L5-1.8 mm long. Style 3.5- 4 mm long, curved towards apex; beard hairs 0.6-0.8 mm long. Ovules 8-10. Distribution. Widespread in inland south-western Western Australia from Dowerin to Wickepin and east to Peak Charles and East Mt Barren. 374 Nuyuia Vol. 7, No. 3 (1991) Figure 30. Hololype of Verticordui tumUla subsp. iherogana. Scale in cm. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 375 Etymology. Named from the Latin tumidus (swollen), in reference especially to the reflexed appendages of the hypanthium. The broad hypanthium with rounded ribs and large swollen appendages and the 8-10 ovules particularly distinguish this species within sect. Verticordella. The flowers are large and bright pink, usually continuing throughout summer. There are 2 subspecies. Key to subspecies Hypanthium constricted towards base, prominently angular; sepal lobes 9 or 10, the reflexed cilia few; petal fringe coarse, the segments ± serrate towards base subsp. tumida Hypanthium not constricted towards base, obscurely ribbed; sepal lobes 5-8, the reflexed cilia numerous and often auriculate; petal fringe not or very sparsely serrate subsp. therogana A.S. George Verticordia tumida A.S. George subsp. tumida Hypanthium somewhat constricted and angular below appendages; appendages 1.5- 1 .8 mm long; sepal lobes 9 or 10, the reflexed cilia few. Petal fringe usually ± serrate towards base. Distribution and habitat. Occurs mainly between Dowerin and Charles Gardner National Park, with outliers E to Bronti and S to Jitaming (Figure 40). Grows in sand, rarely in laterite, in heath. Flowering period. Late October-April. Conservation status. Not rare or endangered. Verticordia tumida subsp. therogana A.S. George, subsp. nov. Ab Verticordia tumida subsp. tumida ciliis reflexis sepalorum plus numerosis, hypanthio ad basin minus anguloso appendiculis 1-1.3 mm longis, sepalorum lobis 5-8, petalorum fimbriis integris gracilioribus, praecipue differt. Typus: N of Hyden on Mt Walker South Road, Western Australia, 30“ 09' S, 1 18° 43' E, 22 November 1985, D.B. Foreman 1161 (holo: PERTH; iso: AD,CANB, MEL). Figure 30. Differs from subsp. tumida especially in the more numerous reflexed cilia of the sepals, the hypanthium less angular towards the base and with reflexed appendages 1-1.3 mm long, the sepal lobes 5-8, and the fimbriae of the petals simple and more slender. Distribution and habitat. Widespread in the southern agricultural regions of Western Australia, from Wickepin to Peak Charles and S to East Mt Barren (Figure 40). Grows in sand, sandy loam, gravelly sand and quartzitic sand, in heath and mallee shrubland. 376 Nuytsia Vol. 7, No. 3 (1991) Flowering period. Late October-March, but recorded as late as May. Conservation status. Not rare or endangered. Etymology. From the Greek theros (summer) and ganos (brightness); the subspecies usually flowers throughout summer and has bright pink flowers. This subspecies is variable and should be studied in more detail. The reflexed cilia of the sepals are sometimes few, as in subsp. tumida. The petal fringe varies from fine and smooth to coarse and scabrid, sometimes with a few teeth but not as serrate as in subsp. tumida. Collections from the Wickepin area, e.g. D.B. Foreman 1108 (CANB, MEL, PERTH), are morphologically closest to subsp. tumida. Verticordia venusta A.S. George, sp. nov. Ad Verticordiam muellerianam E.Pritzel affinis, a qua folds minoribus, floribus roseis, stylo breviore minus curvato pilis brevioribus, differt. Folia obovata-elliptica, plerumque 2-4 mm longa, L5-3.5 mm lata. Stylus 5 mm longus, pilis 0.2-0.3 mm longis. Typus: by railway, S of Manmanning, Western Australia, 30" 55' S, 1 17° 06' E, 28 November 1983, B.H. Smith 318 (holo: PERTH; iso: AD, CANB, HO, MEL). Related to V. muelleriana, from which it differs in the smaller leaves, pink flowers, and shorter less curved style with shorter beard hairs. Leaves obovate-elliptic, usually 2-4 mm long, 1.5-3 .5 mm wide. Style 5 mm long, with hairs to 0.2-0.3 mm long. Distribution and habitat. Widespread in NE agricultural areas of Western Australia, from Perenjori to Wongan Hills and E to Bencubbin (Figure 41). Grows in yellow sand and occasionally in gravelly sand, in heath and shrubland. Flowering period. Late October-January. Etymology. From the Latin venustus (charming, lovely), in reference to the appearance of the plant in flower. This species has long been considered a variant of V. muelleriana but may be distinguished from that species especially by the smaller leaves and the less-curved style with a beard of shorter hairs. Usually the flowers are rose-pink in contrast with the maroon of V. muelleriana. One collection, NNW of Wubin, 20 October 19S4,A.S.George 16419 (PERTH), has leaves to 5 mm long and 4 mm wide. A.S. George, Verlicordia (Myrtaceae; Chamelaucieae) 377 Verticordia verticordina (F. Muell.) A.S. George, comb. nov. Chamelaucium verticordinum F. Muell., Fragm. 4: 57 (1864); Darwinia verticordina (F. Muell.) Benth., J. Linn. Soc., Bot. 9: 181 (1865). Type: towards Cape le Grand, 18-, G. Maxwell s.n.; n.v. The taxonomic position of this species has been a problem for many years, since it lay uneasily in either Darwinia or Chamelaucium. Both Mueller and Bentham considered it to have some characters of Verticordia, yet largely because of the scarcely divided sepals it was not included in this genus. The overall morphology is, in fact, very similar to that of Verticordia sect. Infuscata, especially the habit, leaves, hypanthium, androecium, style and ovary. The sepals, being unlobed but erose to lacerated, are certainly atypical in Verticordia, but they have the thin scarious margins of many species, unlike the thick texture in Chamelaucium. Very shortly divided sepals also occur in V. cooloomia and V. lepidophylla var. quantula. The long style, noted by Bentham as ‘rare in Verticordia’, occurs in a number of species discovered since he wrote the account for "Flora Australiensis". The species also has 2 ovules, in contrast to the 6-10 ovules found in all species of Chamelaucium. Darwinia is now restricted to laxa with a multiple-flowered inflorescence (N.G. Marchant pers. comm.). Because of the almost entire sepals V. verticordina is placed in its own section, Elachoschista (see above). Verticordia vicinella A.S. George, sp. nov. Ad Verticordiam minutifloram F. Muell. affinis, a qua ramulis florentibus magis corymbiformibus, floribus plerumque rosaceis vel lilacinis, raro luteolis, sepalorum divisionibus tenuioribus, petalis pubescentibus, staminibus majoribus (c. 0.5 mm longis), staminodiis majoribus (c. 0.5 mm longis) glandulosis, et barba styli pro parte majore extensa, differt. Typus: near Arboretum, Esperance, Western Australia, March 1988, T. Daniell s.n. (holo: PERTH; iso: CANB, K, MEL). Related to V. minutiflora, from which it differs in the more corymiform floral branchlets, the usually pink or lilac flowers, rarely yellowish, the more slender divisions of the sepals, the pubescent petals, the larger stamens (c. 0.5 mm long), the larger (c. 0.5 mm long) glandular staminodes, and the style beard extending for a longer distance. Distribution and habitat. Occurs mainly from Esperance to Mt Ragged, Western Australia, with a record from the rabbit-proof fence S of the Ravensthorpe-Esperance Highway (Figure 33). Grows in sand, often low-lying, in heath. Flowering period. January-April. Conservation status. 3RC. Etymology. Named from the Latin vicinus (neighbouring) with the diminutive suffix -ella, in reference to the small flowers and close relationship with V. minutiflora. 378 Nuytsja Vol. 7, No. 3 (1991) Figure 3 1 . Holotype of Verticordia wonganensis. Scale in cm. A.S. George, Verticordia (Myrtaceae: Chamelaucieae) 379 This species is closely related to V. minutiflora but usually has pink or lilac flowers, more numerous sepal divisions, slender, pubescent petals, larger stamens and staminodes, and the beard extending over a longer portion of the style. The habit, especially that of the flowering branchlets, is more corymb-like. The species also grows in a different habitat, V. minutiflora usually being on granitic slopes. Verticordia wonganensis A.S. George, sp. nov. Ad Verticordiam drummondii Schauer arete affinis, a qua floribus majoribus sed stylo breviore, laete roseis, et florescentia praecoci, praecipue differt. Pedunculi 1-1.5 mm longi. Hypanthium 2.5 mm longum, costatum, appendiculis reflexis 1.5 mm longis acutis. Sepala 5-6 mm longa, lobis 7 vel 8, non auriculata. Petala 5-6 mm longa, fimbriis 10-12 c. 2 mm longis inclusa. Stamina 2 mm longa; staminodia 1.6 mm longa. Stylus 4-5 mm longus, ad apicem curvatus; pili barbae 0.4 mm longi. Ovula 6. Typus: WonganHillsFloraReserve, Western Australia, c. 30“52'S, 1 16° 43' E, 21 November 1961, R.D. Royce 6734 (holo: PERTH). Figure 31. Closely related to V. drummondii, from which it differs especially in the larger pale pink flowers but with shorter style, and the earlier flowering period. Peduncles 1-1.5 mm long. Hypanthium 2.5 mm long, ribbed, with acute reflexed appendages 1 .5 mm long. Sepals 5-6 mm long, with 7 or 8 lobes, not auriculate. Petals 5-6 mm long, including 10-12 fimbriae c. 2 mm long. Stamens 2 mm long; staminodes 1.6 mm long. Style 4-5 mm long, curved towards apex; beard hairs to 0.4 mm long. Ovules 6. Distribution and habitat. Restricted to a few localities N and NE of Wongan Hills, Western Australia (Figure 37). Grows in yellow and white sand, rarely in gravelly sand, in shrubland. Flowering period. November-December. Conservation status. 2RC. Etymology. Named after Wongan Hills, the town near the area of distribution. Taken in the context of the other taxa now recognised in Verticordia sect. Verticordella, this is worthy of specific rank. It is closest to V. drummondii but differs as outlined in the diagnosis. 380 Nuytsia Vol. 7, No. 3 (1991) Acknowledgements My interest in Verticordia goes back to my early years at the Western Australian Herbarium (PERTH). The Curator at that time. Bob Royce, and his successor John Green, encouraged my research. Paul G. Wilson, Senior Botanist at PERTH since 1964, has always been ready to assist in various ways. Since I left PERTH, the technical assistants there have readily processed loans of specimens to and from Canberra. Loans of specimens have been received from many herbaria, whose administrators and staff are gratefully acknowledged. These herbaria are B, BM, BRl, CGE, K, KW, LD, MEL, NY, PERTH, W. The administrators of the following herbaria made facilities available during visits: AD, B, BM, BRI, CANB, CBG, E, FI, G, K, M, MEL, NSW, NY, P, PERTH, W. Some of these I visited during my term as Australian Botanical Liaison Officer at the Royal Botanic Gardens, Kew, in 1968. Many people have assisted either during my field work or by submitting collections. In particular, I acknowledge Elizabeth Bemdt, Basil and Mary Smith, Margaret Pieroni, Pat and Norm Moyle, Eileen Croxford, Phil Roberts, the late Charles Chapman, Bob and Betty Wemm, Norm and Jane Stevens, Geoff and Rosemary Cugley, Tony Annels, Thelma Daniell, John and Judy Browne, Marg Murfit, Don and Barbara Bellairs, Evelyn and the late Fred Humphreys, Bert Main, Max Hewett and Philippa Nikulinsky. Cathy Miller, Canberra, prepared the scanning electron micrographs of anthers and floral details, and the prints used in this paper. Denis Carr and the late Maisie Carr, Canberra, were unfailingly helpful with discussions, suggestions and advice, especially in relation to the study of anthers. The Bureau of Flora and Fauna, Canberra, supported a field trip to Western Australia in 1984, as well as visits to Australian herbaria made in conjunction with the Flora of Australia project. With virtually no other research time available at the (then) Bureau, this project has entailed long hours at weekends and evenings. Elizabeth George provided much assistance and encouragement. Several of the then Bureau staff, in particular Savita Meek, Rachel Kentwell and Dawn Donald, assisted with typing and making up figures. In 1 984 the (then) Department of Fisheries and Wildlife of Western Australia provided collecting permits for a field trip. The Minister of that portfolio gave permission to collect material of Verticordia staminosa, a gazetted rare species. A number of constructive criticisms by the Nuytsia editorial board and an anonymous referee highlighted aspects of the paper needing improvement. A.S.

Printing is now done using a desktop publishing system. After final acceptance of pa^rs authors are requested to provide floppy discs readable direcUy by IBM computer. Wherever possible, the MS-WORD software should be used in conjunction with a customized style sheet, available from the editor with comprehensive instractions for its use. Alternatives should be discussed with the editor before preparing manuscripts. Great cate with layout, spacing and typography must be exercised in the preparation of electronic manuscripts. In particular, note the following. Text is not to be right-justified. Where manuscripts are compiled with software other than MS-WORD all headings and paragraphs are to be left-justified. Within a paragraph two spaces are required between sentences; after colons, semicolons, commas and dashes a single space is required. Where MS-WORD is used, text should be italicized or emboldened where appropriate. Original figures should not be lettered but instead accompanied by copies indicating lettering. Galley proofs will be forwarded to authors for checking. Twenty reprints of each paper will be provided to authors free of charge; no additional copies may be ordered. Style and layout should follow recent numbers of Nuytsia. Note particularly the following. Title. Should include the family name of genera or species treated. New taxa should be named if not numerous. The geographic area of study should be given. Abstract. The paragraph (or paragraphs) should be indented and commence with bibliographic information. New taxa, combinations and names should be listed. The major contents of the paper should be summarised but no additional material given. Key words indicating all ideas and topics coveted by the paper must be included to facilitate computerised abstract searching. Headings. All headings should be in capitals and lower case, major headings being centred and minor ones left-justified. Keys. May be either indented (e.g. Nuytsia 5: 277) or bracketed (e.g. Nuytsia 5: 84). Indented keys involving mote than nine levels of indentation should be avoided. Note that use of the MS-WORD style sheet (see above) considerably facilitates the layout of both indented and bracketed keys. Species treatments. Use of certain named paragraphs, or sets of paragraphs, for matter following the descriptions is encouraged. The desired sequence and examples of commonly used headings are shown below. Recommended headings which are italicised below, should be left-justified, followed by text on the same line. (1) Taxon name, synonymy (if any) and type details (for previously published taxa). (2) Latin (for new taxa - indented). (3) Typusi (for new taxa - not indented). (4) English description (indented). (5) Other specimens examined or Selected specimens examined, as appropriate, preferably including number of collections examined. (6) Distribution. (7) Habitat. (8) Flowering period. (9) Fruiting period. (10) Typifica/ion (discussion). (11) Affirdties or Relationships. (12) Discussion or Comments OT Notes. (13) Conservation status. (14) Etymology. Synonymy. The desired format is that used by P.G. Wilson, Nuytsia 4: 135-262. Staruiard abbreviations. It is suggested that where possible the following standards be adhered to. (1) Author abbreviations — Anon. (1980). Draft index of Author Abbreviations Compiled at the Herbarium, Royal Botanic Gardens, Kew. (HMSO: London.) (2) Book titles in literature citations — Stafleu, F.A. & Cowan, R.S. (1976-83). Taxonomic Literature. Edn 2. (I.A.P.T.: Utrecht.) (But with Capital initial letters.) — Green, J.W. (1985). Census of the Vascular Plants of Western AustraUa. Edn 2. Pp. 20-24. (Department of Agriculture: Perth.) (3) Journal titles in literature citations and reference lists — Lawrence, G.H.M. et al. (1968). "B-P-H (Botanico-Periodicum-Huntianum)." — Green loc. ciL Figures. Numbers should follow a single sequence including maps. Structure of papers. Authors are encouraged to use the conventional structure of scientific papers when a complete study is being reported (e.g. a revision). A methods section should include the method of drawing up the descriptions from specimens, exterrt of search for ty^s, and discussion of concepts for choice of taxonomic categories. A discussion section should be considered, which would include some or aU of the following: a summary of the findings, emphasising the most significant; interpretation of the results in the light of other relevant work; statement of new problems which have arisen; advising of aspects which are to be followed up; suggestion of topics which others might useful^ pursue; prediction and speculation. ■ \ / ♦ CONTENTS ♦ New taxa, combinations and typifications in Verticordia (Myrtaceae: Chamelaucieae), By A.S.
