Which is a type of grass, Pleurothallis or Lamarckia?
Pleurothallis Pleurothallis, abbreviated Pths in horticultural trade, is a genus of orchids commonly named bonnet orchids. The genus name is derived from the Greek word 'pleurothallos', meaning 'riblike branches'. This refers to the rib-like stems of many species.
Paracaleana Paracaleana commonly known as duck orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. Orchids in this genus are similar to "Caleana major", but there are differences in the flowers and in the insects that pollinate them. "Paraceleana" orchids, as well as hammer orchids ("Drakaea") are pollinated by male thynnid wasps. Duck orchids have a single leaf and one or a few, dull-coloured, inconspicuous flowers.
