Although this moss is generally referred to A. siellatum, it is really far 

 more related to the last species, and just as nerveless leaves are found on the 

 latter, so we occasionally find on the present leaves faintly nerved half- 

 way. The multipinnate trailing stems closely clasping the stones is quite 

 characteristic, and with the highly attenuated leaves and perichaetial bracts, 

 give it more than a varietal distinction.
