 — Var. /8. Organ Mountains, elev. 4000 feet, Gardner. — My specimens of this 

 handsome Fern exhibit two forms, which I dare not venture to consider distinct. 

 In the very glossy and ebeneous stipes and racliis the var. /3 mostly resembles the 

 figure and description of Raddi, but differs in the very obtuse pinnules and in 

 the bluntly crenated, not serrated margins.

 stipes 6 inches and more long stout and as well as the entire

 pinnae 24 or more 4-5 inches long rather distant broad-lan- 

 ceolate sabhorizontally patent moderately acuminate, pin- 

 nules shortly petiolate rhombeo-ovate or obovate subacute 

 coarsely and unequally serrated, the base entire superior 

 parallel with the rachis inferior subexcised terminal ones 

 subconfluent, rachis herbaceous dark-coloured below (not 

 at all ebeneous), veins only seen when the frond is held 

 between the eye and the light pinnated erecto-patent rather 

 distant simple or forked terminating within the margin and

 destitute of caudex, it is so distinct from any species known to me, that I can
