Cryptandra exserta is a flowering plant in the family Rhamnaceae and is endemic to inland Western Australia. It is a shrub with narrowly oblong leaves and clusters of white, tube-shaped flowers.
Description
Cryptandra exserta is a shrub that typically grows to a height of up to about {{cvt|50|cm}}, its young stems densely covered with matted hairs. The leaves are narrowly oblong, {{cvt|2.3–2.5|mm}} long and {{cvt|0.5-0.7|mm}} wide, on a petiole about {{cvt|0.3|mm}} long with stipules {{cvt|0.6–1.0|mm}} long at the base. The edges of the leaves are turned down or rolled under, sometimes concealing the hairy white lower surface. The flowers are borne in spike-like clusters of 2 to 5, sometimes up to 10, on the ends of branchlets. The flowers are surrounded by about 10 broadly egg-shaped to oblong bracts. The floral tube is about {{cvt|2.5|mm}} long, the sepals {{cvt|2.0–2.5|mm}} long and densely hairy. Flowering occurs from July to September.{{cite journal |last1=Rye |first1=Barbara L. |title=New species and keys for Cryptandra and Stenanthemum (Rhamnaceae) in Western Australia. |journal=Nuytsia |date=2007 |volume=16 |issue=2 |pages=363–364 |url=https://florabase.dpaw.wa.gov.au/science/nuytsia/462.pdf |access-date=16 November 2022}}{{FloraBase|name=Cryptandra exserta|id=31615}}
Taxonomy and naming
