462 Observations on Ferns 



This fern is a great pest to the cultivator, in those soils in which it 

 has established itself, for there is great difficulty in eradicating it, the 

 roots running very deep into the earth. It grows 10 feet high, and 

 much resembles P. aquilina in habit. 



Too common in St. Elizabeth's and Manchester. 



Asplenium, Linn. 



1. A.serratum, Linn.; Plum. Fil. 124; Willd. Sp. PI. vol. 



v. p. 304. 



Grows in large tufts on the honey-combed rocks in the Mayday 

 Mountains. 



2. A. ambiguum, Raddi; Raddi Fil. tt. 54, 54 bis; Spreng. 



Syst. vol. iv. p. 82; (A. Shepherdii). 



I believe the fern figured by Raddi to be the same as Sprengel has 

 named A. Shepherdii : Raddi's name being the oldest, of course must 

 stand. It occasionally has the sori of a Diplazium. 



Common in the woods near Old England plantation, Manchester. 



*3c} I 3. A. obtusifolium, Linn.; Icon. Fil. t. 23J; Willd. Sp. PI. 

 vol. v. p. 314. 

 Common in similar situations, with the preceding. 



4. A. brasiliense, Raddi; Raddi Fil. t. 51. Jig. 1. 



Woodsides at the back of the Mayday Mountains- 



5. A. auritum, Sw. ; Sloane Jam. t. 31. ff. 1, 2 ; Willd. Sp. 



PI. vol. v. p. 326. 

 Found with the preceding. 



6. A. dentatum, Linn. ; Icon. Fil. t. 72; Will. Sp. PI. vol. v. 



p. 324. 



On living trees in the woods between Old England and Albion plan- 

 tations, Manchester. 



7. A. rhizhophorum, Linn. ; Willd. Sp. PI. vol. v. p. 334. 



Willdenow has quoted Sloane, tt. 29, 30, but those plates are figures 

 of Poly podium rep tans. The description answers very well for my plant, 

 except that the pinnce are scarcely " sub-auritis." 



Rather common in damp ravines in woods in the Mayday Mountains. 



8. A. praemorsum, Sw. ; Pluk. Aim. t. 73, p. 5 ; Willd. Sp. PI. 



vol. v. p. 339. 

 Common in the woods; Mayday Mountains. 



CjENOPTEMS, Berg. 



C. myriophylla, Sw.; Willd. Sp. PI. vol. v. p. 301. {Darea).
