on the upper side with dense whitish lanceolate dentato- 

 ciliated scales eraarginate at the base and subpeltate, and on 

 the under side with ferruginous scales of the same nature, 

 the surface of the pinnae bright-green when tlie scales are re- 

 moved, veins immersed close compact simple or forked clothed 

 with the narrow elongated sori for nearly their whole length 

 and which are (like the veins) simple or forked, rachis ebe- 

 neous-black paleaceous with imbricated linear lanceolate sub- 

 ferruginous appressed scales, longer and less toothed at the 

 margin than those of the pinnae. (Tab. CCXCV.) 



Ilab. Fort Cooper, North-east Australia, Edward Bowman, Esq. Received in 

 1862 from Dr. Mueller. — It would be idle to speak of the great acquirements 

 and the unbounded liberality of the prince of Australian botanists, Dr. Mueller, 

 F.R.S. of London, and Government botanist at Melbourne, who must ever rank 

 with the noble-hearted Dr. Wallich amongst botanists. To Dr. Mueller I owe 

 the only specimens of this very remarkable Fern that have yet been detected. 

 They are sufficient to show a considerable affinity with a plant of a widely diffe- 

 rent and alpine country in the northern hemisphere, viz. G. vestita : in tlie latter, 

 as described under the preceding species, the clothing of the pinnae on both sides 

 consists of the most delicate and finest of soft silky hairs ; this has the pinnae and 

 the rachis equally clothed with lanceolate membranaceous closely reticulated 

 fringed scales. 



40. G. (Eugymnogramme) tomentosa, Desv. ; caudex short 

 erect, stipites 4-12 inches long tufted purple-ebeneous as 

 well as the rachis and both (when young especially) villous 

 with patent fulvous hairs, fronds also villoso-subtomentose 

 6-12 inches long submembranaceous acuminate or (in the 

 more compound specimens) ovate pinnate with the pinnee 

 1-2 inches long petiolate, lower ones and often the terminal 

 ones cordato-ovate with 1-2 deep lobes at the base, upper 

 ones narrower and entire generally bipinnate and even sub- 

 tripinnate, lower primary pinnae 4-6 inches long their pinnae 

 as in those just described, terminal ones often hastate or even 

 pinnatifid, veins very close compact bi-trifurcate with the nar- 

 row linear sori covering the whole back of the frond. — Desv.

Hab. Brazil, about Rio, all collectors, Gardner, n. 14 and 4077. Peru, M'Lean, 

 Mathews, n. 1815. — Notwithstanding the close affinity of the simply-pinnated 

 forms of this Fern with the G. rufa, leading to the belief that they may both be 

 forms of one species, I have among my numerous specimens no certain G. rufa 

 from Brazil anywhere south of the Amazon, where G. tomentosa is so abundant, 

 while all my specimens of G. rufa are from north Brazil.
