 leaves, hemispherically prominent, monoecious. Paranemata simple. — 

 Carpoglossum [Kutz.),ivoxa Kapiro'^, fruit, q\\& >y\a>aaa, a tongue;

 posita ; phyllodiis verticaUter applanatis, immerse costatis. Receptacida pro- 

 pria et vesicidcB nullcB. Scaphidia in utraque pagina foliorum sparsa, hemi- 

 sphcerice prominentia, monoica. Sporce obovoidece, subsessiles. Paranemata 

 simpliciiiscula. 



Carpoglossum angustifolinm ; frond laxly pinnated ; stem two-edged, 

 broader than the patent pinnatifid phyllodia; pinnules linear, very

 edged or flat, with a thickening or rib in the middle, slightly zigzag, naked 

 below for several inches, or a foot or more above the base, thence to the 

 summit regularly pinnate or l)ipinnate; the general outline lanceolate or 

 ovato-lanceolate. PinntB alternate, issuing from the sharp edge of the 

 stem, erecto-patent, \-l\ inch apart, deeply pinnatifid or bipimiatifid, 

 with linear, entire lacinia3, l-l-^ Hne wide, 1-1 1 inch long, very obtuse. 

 Receptacles formed from the lacinia^ or pinnules, not much altered or swollen, 

 but pierced with a double row of pores, under which are placed the spore-
