Drosera peltata
''Drosera peltata'', commonly called the shield sundew〔Salmon, Bruce. 2001. ''Carnivorous Plants of New Zealand''. Ecosphere Publications.〕 or pale sundew,〔Erickson, Rica. 1968. ''Plants of Prey in Australia''. Lamb Paterson Pty. Ltd.: Osborne Park, Western Australia.〕 is a climbing or scrambling perennial tuberous species in the carnivorous plant genus ''Drosera''. Among the tuberous sundews, ''D. peltata'' has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves.〔Bruce Salmon, ''"Carnivorous Plants of New Zealand"'', Ecosphere publications, 2001〕 It is either a single extremely variable species, or a complex of several closely related species of uncertain taxonomic boundaries. In Australia at least four forms have had or still have specific taxonomic recognition: ''Drosera peltata'' subsp. ''peltata'' (an autonym), ''D. peltata'' subsp. ''auriculata'', ''D. foliosa'' (also as ''D. peltata var. foliosa'') and ''D. gracilis'' (also as ''D. peltata var. gracilis'').〔Tasmanian Herbarium ''(Flora of Tasmania Online, Tasmanian Museum and Art Gallery )''〕〔 Australian National Herbarium ''(Australian Plant Name Index )''〕
Tuberous sundews are species of the genus ''Drosera'' that have evolved to live in summer drought conditions and aestivate as a dormant underground tuber. While many tuberous sundews are ground-hugging rosettes, ''D. peltata'' is an upright species with a simple or branching inflorescence.〔D'Amato, Peter. 1998. ''The Savage Garden: Cultivating Carnivorous Plants''. Ten Speed Press: Berkeley, California. pp. 152-157.〕
== Description ==
''Drosera peltata'' is a perennial tuberous herb. Its underground tuber is generally found 4 - 6 cm under the soil surface, and its aerial parts range from 5 - 50 cm in height, with wide differentiation into several forms. The subspecies ''D. peltata'' subsp. ''auriculata'' is often the most robust, reaching up to 50 cm in height, whereas the form known informally as ''D. foliosa'' tends to be the shortest, often only 5-10 cm.〔The Student's Flora of Tasmania. W.M. Curtis. 1967. St. David's Park Publishing, Hobart, Tasmania. Vol. 3, p. 536〕 ''Drosera peltata'' generally has an evident rosette of leaves at the soil surface, which is most pronounced in ''D. foliosa'' and in contrast often reduced to scales in mature plants of ''D. peltata'' subsp. ''auriculata''. The aerial stem is simple or slightly branched in the nominal form of ''D. peltata'', as well as in ''D. peltata'' subsp. ''auriculata'', and the form informally known as ''D. gracilis''.〔 Flowers are variable in color, but generally white or light pink. The colour of the plants is also highly variable, with ''D. foliosa'' generally bright grass green even when growing in direct sunlight, ''D. peltata'' subsp. ''auriculata'' often tinged with variable amounts of red (or even solid red), and ''D. gracilis'' always orange or dark red colour.
