Caladenia longicauda subsp. extrema, commonly known as the late white spider orchid[1] or Seaton Ross spider orchid[2] is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It has a single hairy leaf and one or two mainly white flowers with long, mostly spreading lateral sepals and petals. It is a relatively rare orchid which is similar to the tangled white spider orchid (subspecies redacta) but has larger flowers and a later flowering period.
