Anogramma sp. in Morialta and Horsnell Gully Conservation Parks
There are about 7 to 10 species (depending on the source of information) of these small ferns. They are generally regarded as widespread, but the species recorded in Morialta Conservation Park: Anogramma leptophylla is listed as Rare in South Australia.
The name Anogramma is derived from Greek: ano meaning upwards and gramma a letter, or writing. Texts say this is a reference to the location of the spore producing parts on the backs of the fronds.
Anogramma leptophylla annual fern, looks a little like Cheilanthes austrotenuifolia but can be distinguished by the curved leaflets.
The name, leptophylla means with slender leaves, which are about 8cm long by a few centimetres wide..
Interestingly, the plant only appears on the Morialta Conservation Park plant list, yet the photo above was taken of a specimen found in Horsnell Gully Conservation Park during a working bee. We had been discussing the difference in appearance of the Cheilanthes species, and this specimen was found, along with an example of Cheilanthes austrotenuifolia. At the time we had no idea of what the fern was, that it was rare, or that it was not recorded as growing in Horsnell Gully Conservation Park. If we are able to locate it again, better photos will be taken to allow a positive identification. Once this is done, it will be able to be added to the official plant list for Horsnell Gully.
