1 think there cau be no question of the correctness of the synonyms above 

 adduced, and of the propriety of restoring the oldest name, auriculafum, given no 

 doubt on account of tlic large rounded auricle, which has a peculiar curvature 

 (cristate) towards the rachis, and overlapping it : and which is more or less jjresent 

 in all my specimens: in one, some of these auricles are separated from the main 

 pinna, and form a distinct flabclliform ])innule. Onr present figure will, we 

 trust, help to clear up the ditliculties that have attended the determination of this 

 species. 



74. A. (Euasplenium) ripariuin, Liebm. ; caudex short 

 thick subrepent, stipites 6-8 inches long semiterete chan- 

 nelled in front, frond 1-2 feet long oblongo-ovate or ovate 

 acuminate dark-green blackish when dry (apparently sub- 

 carnose when recent) pinnated, pinnie 15-20 petiolate patent 

 3-4 inches long from an obliquely cuneated base lanceolate 

 acuminate subfalcate, superior base truncated dilated and 

 forming a more or less distinct angle or auricle sometimes 

 slightly sinuato-lobate and rather finely and unequally ser- 

 rated, inferior base more or less excised, terminal one gene- 

 rally broader than the rest more finely acuminated the lower 

 half pinnatifido-lobate, the base equally cuneate and rather 

 long-petioled, veins rather distant once or twice forked ex- 

 tending to the slightly thickened margin not clubbed at the 

 apex always terminating in a tooth, sori linear oblique ex- 

 tending from near the slender vein-like costa almost to the 

 margin, rachis compressed often flexuose. (Tab. CLXIX.)
