'''''Drosera hookeri''''', the '''grassland sundew''' is an shortly erect [perennial](/source/perennial_plant) [tuber](/source/tuber)ous species in the [carnivorous plant](/source/carnivorous_plant) genus ''[Drosera](/source/Drosera)''. ''Drosera hookeri'' is found in south-eastern [Australia](/source/Australia). Although the [holotype](/source/holotype) was collected in [Tasmania](/source/Tasmania), its distribution also includes [Victoria](/source/Victoria_(Australia)), [New South Wales](/source/New_South_Wales) and [South Australia](/source/South_Australia).

== Botanical history ==
This species has a complex taxonomic history,<ref>{{cite web|last1=CHAH (Council of Heads of Australasian Herbaria)|title=''Drosera hookeri'' R.P.Gibson, B.J.Conn & Conran|url=https://biodiversity.org.au/nsl/services/name/apni/230274/api/apni-format|website=Australian Plant Name Index|access-date=24 April 2018}}</ref> and its [specific epithet](/source/specific_name_(botany)) acknowledges the original recognition of the taxon by [Joseph Dalton Hooker](/source/Joseph_Dalton_Hooker).<ref name="gibson2010">{{cite journal|last1=Gibson|first1=R.P.|last2=Conn|first2=B.J.|last3=Conran|first3=J.G.|title=''Drosera hookeri'' R.P.Gibson, B.J.Conn & Conran, a replacement name for ''Drosera foliosa'' Hook.f. ex Planch., ''nom. illeg.''

The nomenclature of ''D. hookeri'' was later clarified<ref name="gibson2010" /> and the taxonomic concept significantly broadened to include most of the south-eastern Australian and [New Zealand](/source/New_Zealand) forms of the [species complex](/source/species_complex) that includes ''[Drosera peltata](/source/Drosera_peltata)''.<ref name="gibson2012">{{cite journal|last1=Gibson|first1=R.P.|last2=Conn|first2=B.J.|last3=Bruhl|first3=J.J.|title=Morphological evaluation of the ''Drosera peltata'' complex (Droseraceae)|journal=Australian Systematic Botany|date=2012|volume=25|issue=1 |pages=49–80|doi=10.1071/SB11030|bibcode=2012AuSyB..25...49G |s2cid=84874795}}</ref>

Like other [tuber](/source/tuberous) sundews, ''D. hookeri'' [aestivate](/source/aestivate)s as an underground tuber to survive summer drought.

''Drosera hookeri'' is a [perennial](/source/perennial_plant) tuberous [herb](/source/herbaceous_plant). Its underground tuber is white and generally found 2 – 5&nbsp;cm under the soil surface. Its aerial parts range from 5 – 10&nbsp;cm in height, normally yellow-green to distinctly yellow in colour. ''Drosera hookeri'' has a well-developed [rosette](/source/Rosette_(botany)) of lunate to semi-orbicular leaves at the soil surface, as well as lunate cauline leaves. The aerial stem is normally branched multiple times from the base of the plant. Flowers are  white, and can appear very close to the basal leaf rosette. The seeds are black and cylindrical.

== Habitat and distribution ==
''Drosera hookeri'' is typically a plant of winter-wet, summer-dry [grasslands](/source/grasslands) and grassy woodlands. It frequently co-occurs with other species in the ''D. peltata'' complex.
