No. 3312 (consisting of 2 separate fronds, each with a portion of the 

 rhizome) seems to me to be different from that of Hewitt (P. coloratum 

 Copel.). My description of P. Cesatianum was based on Christ's determination 

 of Hallier's plant, as is mentioned in Mai. Ferns, and, as long as I have 

 not seen Beccari's specimen, I have no reason to pretend apodictically that 

 Chirst, intentionally or inadvertently, determined the former erroneously. —
