Dicksonia sp. A

This species is very similar to D. youngiae but seems to have a few subtle differences, most pronounced of which is the appearance of the fertile pinnules from above, being rather more markedly dimorphic than D. youngiae (shown below). I have grown D. herbertii from spore in the past, and suspected initially that this is what it might be, but it is forming buds from the trunk (which D. herbertii is not supposed to do).
