Sp. 197. Cystopteris bulbifera. Bernh. Syn, Aspidum Bulbiferum. 

 Swartz. A. Atomarium. Muhl. 



Com. name — Bladder Fern. Frond, lanceolate, elongated. 

 1° — 2° long; 2-pinnate; shaded, moist rocks. — July. 



The four preceding species have been lately separated from 

 Aspidum, the genus that yields the male Fern of the shops. 

 They are equal in every degree I believe to the foreign article 

 and should be attended to. 



Sp. 198. OsMUNDA SPECTABILIS. Willd. 



Com. name — Flowering Fern. Frond 2-pinnate, ^° — 4° 

 high; very smooth; swamps, common. — July. 



Sp. 199. O. Cinnamomea. Linn. 



Com. name — Cinnamon Fern. Frond, pinnate, clothed 

 with rusty wool when young, growing in large bunches, the 

 fertile in the centre, 1° — 2° high ; swamps. — May. 



Demulcent, sub-astringent, corroborant and discutient. — 

 Gives a fine mucilage boiled in milk. Useful in diarrhoea, 

 dysentery, cholera infantum, phthisis, &c. [Raf. Med Flor. 

 2d. 249.] Lindley, [Nat. Syst. Bot. 311.] mentions that they 

 have been given in 3 drachm doses for rickets. I belieye 

 them to be useful, and should be more thoroughly and accu- 

 rately investigated.

The 2 species are equivalent. Diuretic, menagogue, drastic, 

 nervine, alternant aperient and corroborant. Used in dropsy, 

 gout, scurvy, diarrhoea, and suppressions ; externally for tinea 

 plica, &c, in infants ; kills lice, and insects, &c. [Raf. Med. 

 Flor. 2d. 240.] If the half of what Rafinesque says of them 

 be true, some attention should be paid them.

 Sp. 202. Chara vulgaris. 



Com. name — Water Feathers. Aquatic plants, with a foetid 

 small ; among the most obscure of the vegetable kingdom.
