Disphyma crassifolium subsp. clavellatum |
Disphyma crassifolium subsp. clavellatum is the subspecies of Disphyma crassifolium (round-leaved pigface) that occurs in Australia and New Zealand. It is sometimes known by the common name rounded noon-flower[1]
Also called "karkalla" in the Australian native foods trade. However, this name originally only described Carpobrotus rossii and has been misapplied to D.crassifolium as a vegetable.[2]
Description
It grows as a prostrate, succulent shrub or annual herb, from two to 30 centimetres high. Unlike the other pigfaces its leaves are round in cross-section. Flowers are pink, purple or violet.[3]
Taxonomy
This subspecies was first published under the name Mesembryanthemum australe by Georg Forster in 1786, based on New Zealand material. Forster failed to give a description, however, so valid publication of the name falls to William Aiton, who published a description in 1789.[4] In 1803, Adrian Hardy Haworth published M. clavellatum based on plants raised at Kew from seeds collected in Australia.[5] In 1830, N. E. Brown transferred M. australe into Disphyma as D. australe.[6] In 1971 Robert Chinnock published a new species name, D. blackii, for some New Zealand material,[7] and five years later he transferred M. clavellatum to Disphyma.[8]
In the early 1980s,
Distribution and habitat
Disphyma crassifolium is widely distributed in Australia and New Zealand. It grows in saline areas such as coastal dunes and samphire flats, and tolerates a range of soils including sand, loam and clay.[3]
Uses
The leaves have become a popular native vegetable in Australia marketed under the name "karkalla". It typically has a salty flavour and can be used fresh or as a pickled ingredient.[12]
