466 Observations on Ferns 



Frequent at woodsides in the Mayday Mountains. 



Dicksonia, Herit. 



D. cicutaria, Sw.; Sloane Jam. t. 57, ff. 1, 2; Willd. Sp. PL 

 vol. v. p. 487. 

 Common with the preceding. 



Woodsia, It. Br. 



? W '. pubescens, Spreng.; Spreng. Syst. vol. iv. p. 125. 



I am in much doubt if I am correct in this specimen, for I have on- 

 ly Sprengel's short description to compare it with. I found the fern 

 but once ; it was growing in a damp ravine in the Mayday Mountains. 



Cyathea, Sm. 



C. elegans, n. s. 



C. elegans, frondibus glabris tripinnatifidis, pinnulis lineari-lanceolatis 

 apice acuminato, hasi truncatis subsessilibus pinnatifidis ; laciniis subfal- 

 catis obtuse serratis apice rotundato, sori venis primariis approximati, cau- 

 dice arboreo aspero, stipes rachesque aculeati, costs hirsutae. 



Caudex arboreus asper 20 pedales. Stipes 3 pedales aculeati. Frons 6 

 pedalis. Pinnae primariae 2 pedales, secondariae 4 pollicares. Lacinias 4- 

 6 lineares obtuse serratae apice rotundato. Sori glabri venis primariis ap- 

 proximati. Indusium cyathoforme. 



Frequent in the forests in the Mayday Mountains, varying in height 

 from 15 to 25 feet, with a caudex from 6 to 8 inches in diameter. It 

 has a most graceful appearance, the fronds waving with the slightest 

 breeze, are constantly in motion, and create a delicious coolness in 

 their vicinity. 



HYMENOPHYLLEJE, Endl. 



Trichomanes, Linn. 



I T. sinuosum, Rich.; Icon. Fil. t. 13; Willd. Sp. PI. vol. 

 v. p. 502. 



I once found this species climbing up the caudex of Cyathea ele- 

 gans ; it is not unfrequent in the woods in the Mayday Mountains. 



2. T. crispum, Linn.; Icon. Fil. t. 12; Willd. Sp. PI. vol. 



v. p. 504. 



This species varies considerably; my specimens are more acumi- 

 nate and the pinnae more crowded than in the" figure quoted above, 

 but I believe them to be the same. I found it growing on a living tree, 

 (Achras, sp.), on the southern face of the Mayday Mountains. 



3. T. scandens, Linn. ; Plum. Fil. t. 93, (not good) ; Willd. 



Sp. PI. vol. v. p. 514.
