2. Stenochlaena erythrodes (Kunze). 



Acrosticlium erythrodes Kunze, Flora 22 ! : Beibl. 46. 1839. (Type 



from Ilheos, Brazil, Herb. Mart. J 66.) 



Range : Brazil, Prope Ilheos, Herb. Mart. j66 ; Sellow (B) ; 

 Organ Mountains, Gardner (?) 101 (K). 



In Index Filicum, Mr. Christensen refers this plant with two 

 other species of the genus to Stenochlaena marginata (Schrad.) 

 C. Chr., the original of which was described by Schrader in 1824 

 in his report on the ferns collected in Brazil by Maximilian, Prince 

 of Neuwied, as follows : " [Lomaria] marginata : frondibus pin- 



natis ; % sterilium pinnis oblongo-acuminatis subintcgerrimis hast 

 superiori cuneatis glabris indnsiis crenato-incisis rhachi marginata." 

 Goett. Gel. Anz. 871. 1824. In the absence of the type and 

 with such a description it would seem safer to leave this name in 

 the waiting list until more certainty is attainable in regard to its 

 status ; if the description is correct, the plant is not even a Steno- 

 chlaena. In any case the three united species have little in common 

 and can easily be distinguished, when real specimens are at hand. 



3. Stenochlaena Fendleri (D. C. Eaton). 



Lomariopsis Fendleri D. C. Eaton, Mem. Am. Acad. II. 8 : 195. 



I 860. (Type from Venezuela, Fendler JJS-) 



Range: Known only from its type locality. [Figures 9 



and 10.] . 



4. Stenochlaena jamaicensis sp. nov. 



Wide 



Rootstock 1.5-2 cm. in di- 



ameter, densely covered with pallid ciliate scales which are broadly 

 lanceolate to lanceolate-ovate in shape, 2-3 mm. wide ; leaves 

 50 cm. or more long on stramineous stalks 12-14 cm - l° n g> 

 densely covered at the base with scales similar to those of the 

 rootstocks, simply pinnate, 5-io-jugate, the pinnae obtusely 

 cuneate at the base, more or less abruptly tapering at the apex, 

 8-12 cm. long, 2-2.5 cm - wide > the mar g» ns slightly repand and 

 very minutely revolute in drying; veins simple or occasionally 

 forked, inconspicuous, with about 10-11 intercostal spaces to 

 I cm. ; sporophyls 35 cm. or more long, on similar but shorter 

 (8-10 cm.) leaf-stalks, about 9-jugate ; pinnae short-stalked 

 (3-4 mm.), obtuse at base, short-tapering at the apex, 7-8 cm, 

 long by 7-8 mm. wide. [Figures 13 and 14.]
