212 ASPLENIUM, § EUASPLENIUM. 



Hab. Bonin, Dr. Martens {Herb. Nostr. from Imp. Acad. Petersb. : the au- 

 thority for tlie species). This is likewise marked in my lierharium by Mr. Moore 

 " A. Mertensiamun, Kze. ; an A. bulbiferum, var. tripinnatum, Hook. fil. ?" and the 

 same names are similarly attached to a specimen from Benin Islands gathered hy 

 C. Wright, of the U. S. N. Pacif. Eapl. Rrped., and named " Mertensiamnn" i)y 

 Mr. Eaton ; this has some sterile and some fertile pinna; broad, and the fertile 

 segments singularly patent ; and to a specimen given me from Sydney by Mr. 

 Bynoe. — Too near some states of A.Shuttleicorthianum, and, consequently, to A. 

 bulbiferum, var. tripinnatum. 



206. A. (Euasplenium) muUijidiim, Brack. ; " stipites 

 smooth angled sulcate scaly, fronds membranaceous tripin- 

 nate, primary divisions alternate imljricate oblong acumi- 

 nate, pinnules oblong obtuse pinnatipartite, segments litiear- 

 oblong obtuse inferior ones bi-trifid, racbis sparingly scaly, 

 sori semioblong submarginal, involucre entire." Brack. Fil.

 Moore, hid. Fil. p. 23. 



Hab. Tahiti, Society Islands, and Ovolau, Feejee Islands; in damp forests, 

 Brackenridge. — No authentic specimen of this has come under my observation. 

 It must be a large species, "stipes 1^ foot long, and as thick as a goose-quill: 

 fronds 2 feet and upwards in length." •' It is one of the most graceful Ferns of 

 the tribe, and is allied to the A. (Darea) cicutarium of M'illdenow, but that is 

 bipinnate, and its sori shorter." — The figure, however, does not at all accord with 

 our ideas of that species, for it exhibits a primary pinna which alone is 10 inches 

 long and G broad, and is itself tripinnate with very narrow, linear, idtimate pin- 

 nules or segments. May it not be tlie same as A. Shuttleworthianum ? 



207. A. (Euasplenium) davallioides, Hook. ; caudex re- 

 sembling a small oblong erect tuber scaly at the summit, 

 stipites 3-4 inches long tufted compressed and margined 

 below deciduously scaly, fronds 3-6 inches high subcori- 

 aceous, young ones linear oblong simply pinnated with obo- 

 vato-spathulate lobato-pinnatifid pinnse which gradually en- 

 large and become compound forming fronds 5-6 inches long 

 ovate acuminate green 3-subquadripinnate, primary pinnae 

 2-3 inches long petiolate, secondary also petiolate the 

 largest i-f of an inch long broad ovate, ultimate pin- 

 nules small oljlong very patent simple or bifid with seg- 

 ments singularly divaricating often falcato-recurvcd, sori co- 

 pious solitary on the ultimate pinnules or segments occupy- 

 ing the entire segment opening at the margin when on the 

 fork of pinnules often confluent, sori very short oblong, 

 involucre firm-membranaceous spreading (open along with 

 the opposite margin of the segment) overflowing with capsules 

 and looking quite davallioid, rachis broad everywhere com- 

 pressed and winged. — Hook, in Floral, llonykony. in Kew
