Mohria—Named after Molir, a German botanist.

A M O S T beautiful variety of the Mohria thurifraga, (figured
on Plate L X X , vol. viii, of my “ N a tu ra l History of British
and Exotic F e rn s ” ) having the barren fronds from four to
six inches in length, and the fertile fronds from six to nine
inches, the barren being two inches, and the fertile from two
inches and a half to three inches wide. The lower parts of
the fertile fronds (which are erect) are like the barren ones,
the upper pa rt alone being fertile, and much like the fertile
frond of the normal form Mohria thurifraga.
Rhizoma slow creeping.
One of the greatest proofs that this charming Fern is only
a variety of M. thurifraga, is that spores carefully saved and
sown have only produced the ordinary form of M. thurifraga.
For a plant my thanks are due to Mr. Henderson, of
■\Vontworth ; and for the fronds illustrated, to Mr. R, Sim, of
Foot’s Cray.
