    Drosera auriculata (Tall Sundew)

    Botanical Name: Drosera auriculata

    Family: Droseraceae

    Common Name: Tall Sundew

    Drosera from the Greek 'droseros' meaning dewy; alluding to the glistening of the glandular leaf laminae. Auriculata from the Greek 'auricula' meaning ear-shaped.

    Other Names:

    Distribution:
    Commonly found in the southern part of South Australia, from the Flinders Ranges to the lower South-east, growing in moist areas. Also found in Queensland, New South Wales, Victoria and Tasmania
    There are over 100 species worldwide (one source says 188 species)

    Field Notes:
    Very similar to Drosera peltata.

    Often in gravel or rocky soils which dry out in summer. Dappled shade.
    Carnivorous plant with a tuberous root. Single erect stem (occasionally branched) to 50cm long but commonly about 20cm

    Flowering between August and November.

    Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surface. The insects are used to supplement the poor mineral nutrition that sundews are able to obtain from the soil in which they grow.

    Uses:

    None known, but it is reputed to be a good house plant. I guess it would take care of some of the insects !

    One source described it as "mildly toxic", another :

    Other Drosera species are known to have some medicinal uses, but it is not clear if this applies to "all" Drosera:
    "The plant is anodyne, blood tonic and carminative.
    It is used in India in making gold bhasma, which is antisyphilitic, alterative and tonic
    The crushed leaves, with or without salt, have been used as a blistering agent.
    This can be of value as a poultice since it brings more blood to the area and helps speed the clearance of toxins in arthritis and rheumatism"
