Are Coniogramme and Widdringtonia both types of conifer?
Coniogramme Coniogramme is one of three genera in the "Cryptogrammoideae" subfamily of the Pteridaceae family of ferns. A cultivated species, "Coniogramme pilosa", is known as "bamboo fern."
Idiospermum Idiospermum is a genus containing a single species of tree, Idiospermum australiense, found in Australian tropical rainforests. Scientists recognise them as one of the species of the earliest known lineages to have branched out from the first flowering plants and still living today. Since as long ago as 120 million years, they continue living today only in the Daintree and Wet Tropics rainforests region of north-eastern Queensland. They grow naturally only (endemic) in very few locations in north-eastern Queensland (e.g. in Daintree National Park), in the very wet lowland parts of the forest, in groups of 10-100 trees together (rather than scattered individuals). Common names include ribbonwood and idiot fruit .
