CARPOGLOSSUM CONFLUENS, Kutz. 



Gen. Char. Root discoid. Frond with subdistinct stem and leaves, pin- 

 nate; leaves vertically flattened, imperfectly costate. Vesicles and 

 receptacles none. Spore -cavities scattered over both surfaces of the 

 leaves, hemispherically prominent, monoecious. Varanemata simple. — 

 Carpoglossum {Kutz.), from Kap7To<;, /rtdt, and yXwaa-a, a tongue; 

 because the fruit-bearing leaves are tongue-shaped. 



Radix scutata. From caule a foliis subdistincto lieierogenea, pinnatim decom- 

 posita ; phyllodiis verticaliter applanatis, immerse costatis. Receptacula pro- 

 pria et vesicnlce nullce. Scaphidia in utraque pagina foliorum sparsa, hemi- 

 spharice prominentia, monoica. Sporce ohovoidece, subsessiles. Paranemata 

 simpUciusciila. 



Caepoglossum covfiiiens ; frond laxly pinnated or bi-tripinnated ; stem 

 flat, obsoletely midribbed, broader than the erect, simple (or pin- 

 nately compound), very entire, obtusely emarginate, linear-cuneate 

 phyllodia; spore-cavities in many rows.

 Descr. Root a conoidal callus, half to three-quarters of an inch diameter. Frond 

 fourteen inches to 2-3 feet long, when young or dwarfed simply pinnate, 

 when full-grown twice or thrice pirinately compounded. The principal rachis 

 and the rachides of the larger branches of old fronds are 5-8 lines wide, ta- 

 pering to the base, broader upwards, and again slightly narrowing to the 

 blunt extremity, flat, imperfectly midribbed, sharp-edged, and perfectly entire. 

 All the divisions stand very erect and have rounded axils. The ultimate 

 segments are hnear-cuneate, half an inch wide or less, narrowed at base, 

 minutely notched at the apex, and linear-oblong or somewhat cuneate ; if
