198 ASPLEXIUM, § EUASl'LENIUM. 



— If, as I believe, the A. Richardi sliould be kept distinct from Aspl. adiantoides 

 of Uaoiil, I think A. Colensoi of Hook. fil. {olim) will better rank with it than 

 with the latter {A. Hookeriannm, Col., our n. 191), and, rather with the Dare- 

 astrum-^rouyi of the genus, than with our previous group of Composi/ce varue. 

 Not that much stress should be laid on this circumstance, for we see it often occur 

 that the character of the two groups are found in the same species. Under this 

 species in Ic. Plant, t. 977, Dr. Hooker has well remarked that "as materials in- 

 crease in our collections, so do the difficulties of discriminating the species increase." 

 Our var. is not far removed froui some states of A. cicutarhim : but this latter 

 is a much more delicate and elegant plant. 



180. A. (Euasplenium) cicutarium, Svv.; caudex stout erect 

 scaly above, stipites tufted 3-4 inches to a span and more high 

 livid-green sometimes marginato-alate fronds G-8 inches to a 

 foot and a half long firm-membranaceous bright-green broad 

 ovato-lanceolate bipinnate, pinnce horizontal subsessile from 

 a rather broad truncated base oblong-lanceolate more or less 

 acuminate 2-3 inches long, pinna; shortly petiolate about 

 -.s an inch long ovate obtuse pinnatifid with 8-10 linear acute 

 bi-tridentate or entire segments superior basal segment au- 

 riculiform and often distinct cuneate subpinnatitid, lowest 

 pairs of the pinnee reflexed upon the main rachis and cristate 

 those of the apex linear entire confluent quite dareoid, veins 

 pinnated one to each segment, sori on the disc of the larger 

 pinnules in two rows oblong often small, those on the termi- 

 nal narrow segments solitary quite marginal, involucres pale 

 membranaceous, rachises general and partial more or less 

 winged. — Sw. Prodr. j). 130 [excl. syn.). Hook. Gen. Fil. t.
