Leaf and flower detail

Cryptandra arbutiflora, commonly known as waxy cryptandra,[1] is a species of flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia. It is a shrub with spiny branches, elliptic to linear leaves and tube-shaped white flowers.

Description

Cryptandra arbutiflora is a shrub that typically grows to a height of Шаблон:Cvt and has spiny branchlets. Its leaves are linear to oblong with the edges turned down, more or less glabrous, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long. The sepals are Шаблон:Cvt long, the petals white and tube-shaped, the tube part Шаблон:Cvt long with the style usually reaching to near the end of the tube. Flowering occurs from May to November and the fruit is Шаблон:Cvt long.[1][2][3][4]

Taxonomy

This species was first formally described by botanist Eduard Fenzl based on plant material collected by Charles von Hügel from the Swan River area. Fenzl's description was published in 1837 in Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel.[5][6] The Latin specific epithet arbutiflora alludes to the flowers which are reminiscent of those of Arbutus unedo, the strawberry tree.[7]

Four varieties are currently accepted by the Australian Plant Census:

A former variety C. arbutiflora var. intermedia is now regarded as a species in its own right - Cryptandra intermedia.[16]

Distribution and habitat

Cryptandra arbutiflora occurs between the south coast and the Dandaragan area to the north and also near Geraldton.[7][17] It grows in a variety of soils on granite outcrops, breakaways and creek banks.

The variety arbutiflora is found in the Gillingarra to Mount Barker and Jerramungup areas, var. borealis from Kalbarri to the Chapman River, var. pygmaea near Lake Muir, and var. tubulosa from Perth to the Kent River.[4]

Conservation status

Three varieties of C. arbutiflora are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions but var. pygmaea is classified as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[13] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[18]
