This paperdraws attention to five taxawhich are recognized as prioritytaxa for conservation,as well asone Gazetted Rare species, and a furthervariety which has a limiteddistribution, and provides information on theecology of the genus. Methods Descriptionswere made primarily from freshmatedal, supplemented with measurementsfrom herbariumspecimens to ensurethe full rangeof variationwas recorded. Illustrations were prepared from voucheredfresh material or herbariumspecimens. All taxahave been seen in thefield with the exceptionof C intermedia. Terminologywhere appropriate follows McCusker ( 1999).Bractmeasurements aretaken from t}te four innermostbracts. Leaf laminameasurements were made only from branchletleaves as stem leavescan be considerablylarger and vary with stemage. Themain characters used to separatespecies were: presence or absenceof a distinctunderground rhizome;presence of stilt roots;vigour of basalsprouting; angle of matureleaves; leaf lamina shape andindumentum; bract shucture and shape; perianth texture and coloration; anther shape, size and colour;staminal filament length. All specimensheld atBM, CANB,KPBG, PERTH, and UWA atJuly1999 havebeen examined as well as substantialcollections on loanfrom L andMEL. All specimenscollected by J.C.Anway, previouslycited as being held at UWA (Anway 1969),are now at PERTHand have been examined. Furthercollections were made from June to December1999. A completelist ofspecimensexamined is heldat KPBG. Mapswere created using ArcView 3.0 using a combination oflocality data sourced from examined herbariumvouchers, (Western Australian Herbarium 1999, MEL database)and field collections.All specimensexamined with accuratelocality data have been included in the distdbutionmaps. Noteson thegenus Ecology Calectqsia speciesoccupy a variety of habitats,occasionally in seasonallyswampy areas,usually low heathon sandover latedte or graniteor in low woodland on sand. C. browneana,C' hispida and C- narragara are sympatricin kwongan vegetationnear Badgingarta. C. cyaneais restrictedto near- coastalheath on sandover lateritein the Albany region. C. gracilis andC. obrasaare sympatric in low kwongan near Cape Riche with C. gracilis flowering later than C. obtusa. C. grandiflora (lype vatiant) andC. narragara aresympatric in severallocations on theS wan Coastalplain, C. grandiflorafloweing considerablylater than C. narragara. C. intermedia occursin woodland andheath in eastemVictoria and westernSouth Australia. C keigheryi occvs inkwongan in the FitzgeraldRiver National Park ontlle southcoastofWestem Australia.

Br. waskilled. While no voucher specimenswere collected, this study probably refels to C. I randiflora(sortth coast variant), the most common taxon in the Stirling Range. Further study should be made to determinethe effects of P. cinnamomior stilt-rootedspecies. All stilGrootedspecies are thought to bekilled by fire. Hundredsof seedlingshave been observed of C. gracilis(G.Keighery pers. comm.) and C. pignattiana (Brown et al l998) followingfire, while all adultplantshadbeen killed.
