shorth'^ acuminate narrower attenuate at the base, on much 

 longer stipites than the sterile ones yet the summit of the 

 fronds never attains to the height of the sterile. — Fee, Acrost. 

 i. 15. /. 2 {fronds too obtuse, which is rather an abnormal 

 state). Elaphoglossum, Moo?-e, A. tenellum, De^y, ? 



Hab. Brazil, Gardner, n. 98 (the authority for the species) and n. 5927. 

 Bourbon, Richard, n. 274 (unquestionably the same species). — I can almost fancy 

 this to be a small and delicate form of our Aubertii, n. 52, and both inhabiting 

 Bourbon and South America, still the extreme forms appear, at first sight, very 

 dissimilar. 



57. A. (Elaphoglossum) y'ubiyinosum. Fee; caudex hori- 

 zontal creeping stout clothed with dense black subulate im- 

 bricated scales, stipites aggregated towards the apex of the 

 caudex .S-4 inches long in the sterile, a span or a foot and 

 more in the fertile ones reddish-brown furfuraceous with 

 small close-placed subpeltate fimbriated scales dark-coloured 

 in the centre mixed with short subulate black ones; fertile 

 fronds coriaceous 4-5 inches or less to 8-12 inches long J-| 

 of an inch wide near or above the middle, elongato-lanceolate 

 acuminate tapering at the base and generally much so, opaque 

 entire lepidote or scurfy on the upper side with scattered 

 close-pressed dirty-white minute deciduous scales generally 

 long stellato-pilose at the margin beneath almost pubescenti- 

 tomentose with more copious similar scales mixed with stel- 

 late hairs botli of a tawny colour; fertile fronds generally 

 much exceeding the sterile ones on account of the great 

 length of the stipes but they are shorter and narrower, 

 otherwise similar. — Fee, Acrost. p. 47- t.5. f. 1 {very good),

 I. c. p. 49. t. 22. f. 1 {as far as figure and much of the descrip- 

 tion is concerned, but the fronds are not pellucid, yet the re- 



ference is to " Gardner, n. 5928," which is our plant). 



Hab. Tropical America: Columbia, fine specimens, Santa Martha; Ocaiia, 

 Schlim ; Peru, Mathews, n. 1794; Pasco, Cruckshanks (fronds short, stipites 

 very slender) ; Jamaica, Purdie, Wilson, alt. 4000 feet, n. 742; Dominica, i)r. 

 Imray ; Guatemala, Skinner; Mexico, Liehmann {" A. Schiedei," — and this is 

 correctly quoted under A. rubiyinosum by Fee and under A. Schiedei by Moore) ; 

 Brazil, Gardner, n. 5928 {Acr. brachyneuron, Fee, as to figure and reference and 

 much of the description). — The A. tectum of Humboldt is ascertained by Fee to 

 be the A. lepidotum, Willd., though that is a species by no means satisfactorily 

 known ; but Fee has accurately defined and figured the present species, whicii 

 has claim to rank with the section " Polylepideo!."
