Pterostylis praetermissa, commonly known as the Mount Kaputar rustyhood is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It has a rosette of leaves and up to nine relatively small greenish and reddish-brown flowers with transparent "windows" and a reddish-brown, insect-like labellum.
Description
Pterostylis praetermissa is a terrestrial, perennial, deciduous, herb with an underground tuber. It has a rosette of between five and eight leaves, each leaf {{convert|20-35|mm|in|sigfig=1|abbr=on}} long and {{convert|8-17|mm|in|sigfig=1|abbr=on}} wide. Flowering plants have a rosette at the base and up to eight greenish and reddish-brown flowers with transparent panels and which are {{convert|20-25|mm|in|sigfig=1|abbr=on}} long and {{convert|4-5|mm|in|sigfig=2|abbr=on}} wide on a flowering stem {{convert|150-250|mm|in|sigfig=1|abbr=on}} tall. There are between two and five stem leaves with their bases loosely wrapped around the flowering stem. The dorsal sepal and petals form a hood called the "galea" over the column with the dorsal sepal having a narrow point {{convert|2-3|mm|in|sigfig=1|abbr=on}} long. The lateral sepals turn downwards, about the same width as the galea and have thread-like tips {{convert|5-6|mm|in|sigfig=2|abbr=on}} long. The labellum is almost flat, reddish-brown, fleshy and insect-like, about {{convert|5|mm|in|sigfig=1|abbr=on}} long and {{convert|2|mm|in|sigfig=1|abbr=on}} wide. The "head" end has many short hairs and there are between twelve and fifteen longer hairs on each side of the body. Flowering occurs from September to October.{{cite book|last1=Jones|first1=David L.|title=A complete guide to native orchids of Australia including the island territories|date=2006|publisher=New Holland|location=Frenchs Forest, N.S.W.|isbn=978-1877069123|page =323}}{{cite web|last1=Jones|first1=David L.|title=Pterostylis praetermissa|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Pterostylis~praetermissa|publisher=Royal Botanic Garden Sydney: plantnet|accessdate=5 July 2017}}
Taxonomy and naming
Pterostylis praetermissa was first formally described in 1989 by David Jones and Mark Clements from a specimen collected from near the Mount Kaputar National Park and published the description in Australian Orchid Research.{{cite web|title=Pterostylis praetermissa|url=https://id.biodiversity.org.au/instance/apni/488296|publisher=APNI|accessdate=5 July 2017}} The specific epithet (praetermissa) is derived from the Latin words praeter meaning "beyond", "past" or "more than"{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}}{{rp|629}} and missus meaning "sent".{{rp|527}}
