 ciosa, Wall.), is a curious variety from Japan and tlie Himalayas, with the fertile and 

 barren fronds often quite distinct, the former being developed the earliest and soon dis- 

 appearing ; and it also occasionally happens that some of the lateral pinnae become 

 fertile, whilst the terminal ones remain barren. Mr. McKen sends a similar form from 

 Natal.
