183 GENUS LOPHODIUM, 



The following formula may he useful, as affording the means 

 of comparing at a glance the names now proposed for the spe- 

 cies of my genus Lophodium with those adopted hy our syste- 

 matic British botanists for the same plants : the latest edition 

 is quoted in each instance.

Four additional names are introduced into Mr. Moore's 

 'Handbook,' as varieties, — " Smithii," "dumetorum," " an- 

 gusta," and " maculata : " the following are the characters and 

 sjTionymes which accompany them : — ■ 



" y. Smithii : fronds narrowly subtriangular- elongate -ovate, 

 bipinnate ; pinnse opposite horizontal distant ; pinnules nar- 

 rowly decurrent with the slender wing of rachis, oblong obtuse 

 serrated, the serratures incurved ; scales of the stipes dark two- 

 coloured, and except at the base small narrow and scattered. 



" Aspidium spinulosum, Smith, Eng. Fl. iv. 279, according to a speci- 

 men communicated as authentic by Mr. H. Shepherd. 



" S: dumetorum : fronds broadly subtriangular ovate, bipin- 

 nate dwarf; lobes of the pinnules strongly serrated at the ends; 

 scales of the stipes two-coloured but pallid.

" s. angusta : fronds linear-lanceolate bipinnate ; pinnse short 

 deltoid, the inferior and superior pinnules of the lowest pinnse
