CALLIBLEPHARIS PREISSIANA, Ag. 



Gen. Char. Frond flat, cartilagineo- membranaceous, dichotomo-pinnate 

 and fimbriate, formed of two strata of cells ; the medullary stratum 

 of roundish-angular, large cells, in several rows ; the cortical of 

 minute coloured cellules. Fructification: 1, sessile conceptacles, 

 containing, within a thick pericarp, on a basal placenta, a tuft of 

 moniliform spore-threads ; 2, zonate tetraspores, dispersed among the 

 cortical cellules. — Calliblepharis {Kiitz.), from Ka\o<i, heautiful, 

 and /3\e^api<;, literally t/ie eyelashes {cilia), here meaning fringe- 

 like marginal processes.

Descr. Root a minute disc. Fronds 3-10-12 inches high, and as much in the 

 expansion of the branches, dichotomous, very much divided, cut into seg- 

 ments with an average width of 1-3 lines. The primary division is irregu- 

 larly forking, the lower forks at wide, the upper at short intervals ; the
