SixuATUM-MoxKMANii, Monhuan, MS. (Fig. 34.) — Found 

 in 1857, at Hest Bank, Morecombe Bay, near Lancaster, growing 

 sparingly on a tree stump, and named, after testing its constancy 

 for several summers. It is a gem in appearance. Dwarf in habit. 

 An extremely curious plant. The fronds vary as widely as 

 possible in general appearance, being depaviperated, interrupted, 

 laciniated, multifid, and in other respects very irregular. Lobes 

 frequently much shortened, and often wanting; bifid, trifid, 

 crenated, serrated, lacerated, and not unfrequently united 

 throughout, as in the accompanying wood-cut. Fronds some- 

 times ramose. Venation and fructification extremelv confused, 

 but normal on normal fronds which occasionally are sent up.
