Drosera aberrans
Encyclopedia
Drosera aberrans is a perennial
tuber
ous species in the genus Drosera that is native to New South Wales
, South Australia
, and Victoria
. It grows in a rosette
3 to 5 cm in diameter with green, orange-yellow, or red leaves. It is native to southern inland South Australia, southern and central Victoria, and one single collection from New South Wales. It grows in a variety of soils from sand to laterite
gravel and limestone clay in mallee
woodland, heathland
, and open forests. It flowers from July to September.
It was perhaps first illustrated by Ferdinand von Mueller
in 1879, which he identified as Drosera whitackeri [sic], though Allen Lowrie
and John Godfrey Conran note that this could represent artistic license
and may not have been drawn from an actual specimen. Lowrie and Sherwin Carlquist
first formally described this taxon
in 1992 as a subspecies of Drosera whittakeri
. Lowrie and Conran reviewed the specimens of D. whittakeri in 2008 and elevated subsp. aberrans to species rank based on the colony-forming morphology of this species.
Perennial plant
A perennial plant or simply perennial is a plant that lives for more than two years. The term is often used to differentiate a plant from shorter lived annuals and biennials. The term is sometimes misused by commercial gardeners or horticulturalists to describe only herbaceous perennials...
