Cryptandra speciosa is a species of flowering plant in the family Rhamnaceae and is endemic to eastern Australia. It is a shrub with clusters of linear to narrowly elliptic leaves, and clusters white, tube-shaped flowers in leaf axils.
Description
Cryptandra speciosa is a shrub that typically grows to a height of Шаблон:Cvt and has hairy, but not spiny branchlets. The leaves are linear to narrowly elliptic, mostly Шаблон:Cvt long and Шаблон:Cvt wide on a petiole Шаблон:Cvt long and often clustered. There are triangular stipules Шаблон:Cvt long and at the base of the petioles. The edges of the leaves are rolled under, obscuring the lower surface, and the upper surface is glabrous. The flowers are borne singly or in groups of up to 10 in leaf axils, with 6 to 10 broadly egg-shaped bracts at the base of each flower, each flower on a pedicel Шаблон:Cvt long. The floral tube is white, bell-shaped, Шаблон:Cvt long, the lobes erect, Шаблон:Cvt long, and the petals erect and Шаблон:Cvt long.[1]
Taxonomy and naming
Cryptandra speciosa was first formally described in 2007 by Jürgen Kellermann and Frank Udovicic in the Proceedings of the Linnean Society of New South Wales from an unpublished description by Allan Cunningham.[1][2] The specific epithet (speciosa) means "showy" or "splendid".[3]
In the same journal, Kellermann and Udovicic described two subspecies of C. speciosa , and the names are accepted by the Australian Plant Census:
- Cryptandra speciosa subsp. speciosa Kellermann & Udovicic[4] has branchlets with both star-shaped and flattened simple hairs, bracts Шаблон:Cvt long, pedicels Шаблон:Cvt long, sepals Шаблон:Cvt long and petals Шаблон:Cvt long.[1][5][6]
- Cryptandra speciosa A.Cunn. ex Fenzl subsp. strigosa[7] has branchlets with only flattened simple hairs, bracts Шаблон:Cvt long, pedicels Шаблон:Cvt long, sepals Шаблон:Cvt long and petals Шаблон:Cvt long.[1]
Distribution and habitat
Subspecies speciosa grows in sandy soil over sandstone or volcanic rocks, and is found in woodland and Callitris forest on the tablelands of New South Wales to the Victorian Alps near the border with New South Wales. Subspecies strigosa grows on poor soil on sandstone and rocky outcrops between the Narrien Range and Carnarvon National Park in the Leichhardt and South Kennedy districts of central Queensland.[1]
Conservation status
Subspecies speciosa is listed as "critically endangered" in Victoria under the Victorian Government Flora and Fauna Guarantee Act.[5]
