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 {{cvt|0.4–2|m}} and has hairy, but not spiny branchlets. The leaves are linear to narrowly elliptic, mostly {{cvt|2.6–5.1|mm}} long and {{cvt|0.4–0.8|mm}} wide on a petiole {{cvt|0.2-0.7|mm}} long and often clustered. There are triangular stipules {{cvt|1.1–2.0|mm}} 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 {{cvt|0.2–1|mm}} long. The floral tube is white, bell-shaped, {{cvt|2.2–3.5|mm}} long, the lobes erect, {{cvt|1.8–2.7|mm}} long, and the petals erect and {{cvt|1.0–1.6|mm}} long.{{cite journal |last1=Kellermann |first1=Jürgen |last2=Udovicic |first2=Frank |title=A revision of the Cryptandra propinqua complex (Rhamnaceae: Pomaderreae). |journal=Proceedings of the Linnean Society of New South Wales |date=2007 |volume=128 |pages=90–94 |url=https://www.biodiversitylibrary.org/item/110727#page/366/mode/1up |access-date=23 February 2023}}
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in 2007 by Jürgen Kellermann and Frank Udovicic in the Proceedings of the Linnean Society of New South Wales from an unpublished description by Allan Cunningham.{{cite web |title=Cryptandra speciosa |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/614016 |publisher=Australian Plant Name Index |access-date=23 February 2023}} The specific epithet (speciosa) means "showy" or "splendid".{{cite book |author=William T.

In the same journal, Kellermann and Udovicic described two subspecies of C. speciosa, and the names are accepted by the Australian Plant Census:

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.
Conservation status
Subspecies speciosa is listed as "critically endangered" in Victoria under the Victorian Government Flora and Fauna Guarantee Act.
