 — 7, majus ; general characters of the last, but with fronds 

 three to four times as large 1^-2 feet long a span broad with 

 quite the aspect of Aspid. aculeatum, but destitute of involu- 

 cres. — S, Spruceamim ; stipes 1-1 h and more foot long, fronds 

 the same from 5-10 inches wide broad-lanceolate acuminate 

 copious but laxly tripinnate, pinnules all petiolate especially 

 the ultimate one Avhich is always the largest singularly con-

 but the form above described is accompanied by two other specimens, evidently con- 

 sidered by Mr. Spruce to belong to one and the same species : of these, one 

 is a slightly modified form of var. j3, the other intermediate between it and the 

 normal form of var. 7 ; and again other specimens from Condorasto, marked 

 by Mr. Spruce " cfr. n. 5627," are our /3 and y. — This one species of poly- 

 stichoid Poll/podium would furnish a rich harvest to one ardently devoted to 

 the formation of new species on slight grounds, as its near ally Aspid. (Polysti- 

 chum) aculeatum does among true Aspidiacece ; and from some common forms 

 of which the present can hardly be distinguished, but by the absence of in- 

 volucre.
