These photos of N. hastifolia (Anecphya) are from a place
called Girraween Lagoon which is three kilometers from my place
in Australia's Northern Territory. It was also the site where
they filmed the crocodile grabbing Linda Kaslowski by the water
bottle in the first Crocodile Dundee movie. The actual site of
the photos is an overflow of water into a small paperbark swamp.
The water quality and substrate character are recorded in field
notes below.
