It is an uncommon species, endemic and restricted to a few areas in the south-west of Western Australia. It is similar to the other species of Calectasia and has only been recognised as a separate species since a review of the genus in 2001. It is distinguished from the others mainly by the hairiness of its leaves and lack of a rhizome. DescriptionCalectasia browneana is an undershrub with stilt roots but without a rhizome. It grows to a height of about 60 cm with many very short side branches. Each leaf blade is 8.3–15.2 x 0.2–0.4 mm tapering to a short, sharp point on the end and densely covered with fine hairs. The base of the petals (strictly tepals) form a tube 7.2–8.0 mm long, while the outer parts spread outwards to form a pale blue-pink, papery star-like pattern. In the centre of the star are six yellow stamens forming a tube which turns orange-red with age. The thin style extends beyond the stamens.[1] Flowers appear from June to August.[2]Taxonomy and namingCalectasia browneana is one of eleven species in the genus Calectasia. It was described as a new species in 2001 by K.W. Dixon and R.L. Barrett from a specimen collected on the Coorow-Greenhead Road.[3] The specific epithet (browneana) refers to the owners of a property where the species is found and "who have endeavoured to conserve high conservation value kwongan vegetation on their land".[1]Distribution and habitatThis species of blue tinsel lily is uncommon and found in only two, separate areas of the south-west of Western Australia - the Coorow-Eneabba region and near Kalbarri. It grows in white-grey sand over laterite in kwongan vegetation.[1] Conservation statusCalectasia browneana is classified as "Priority Two" by the Western Australian government Department of Parks and Wildlife[2] meaning that is poorly known and from one or a few locations.[4]References1. ^1 2 {{cite journal|last1=Barrett|first1=Russell L.|last2=Dixon|first2=Kingsley W.|title=A revision of the genus Calectasia (Calectasiaceae) with eight new species described from south-west Western Australia|journal=Nuytsia|date=8 January 2001|volume=13|issue=3|page=422|url=https://www.researchgate.net/profile/Russell_Barrett/publication/234814283_A_revision_of_the_genus_Calectasia_(Calectasiaceae)_with_eight_new_species_described_from_south-west_Western_Australia/links/00b49523d24d0055dd000000.pdf|accessdate=18 February 2015}} {{Taxonbar|from=Q15587068}}2. ^1 {{FloraBase|name=Calectasia browneana Keighery, K.W.Dixon & R.L.Barrett|id = 19304}} 3. ^{{cite web|title=Calectasia browneana|url=https://biodiversity.org.au/boa/instance/apni/568169|publisher=APNI|accessdate=8 August 2015}} 4. ^{{cite web|title=Conservation codes for Western Australian Flora and Fauna|url=http://www.dpaw.wa.gov.au/images/documents/plants-animals/threatened-species/Listings/conservation_code_definitions.pdf|publisher=Government of Western Australia Department of Parks and Wildlife|accessdate=11 August 2015}} 5 : Calectasia|Flora of Western Australia|Endemic flora of Western Australia|Commelinids of Australia|Plants described in 2001 |
