ASPLENIUM, § ANISOGONIUM. 269 



simple pinnate, terminal pinna large pinnatifid at the base, 

 primary lateral pinnae U-2 feet long petiolate horizontal ob- 

 long acuminate, pinnules distant horizontal sessile or shortly 

 petiolate from a broad truncate frequently hastate base ob- 

 long gradually acuminated 4-6 inches long varying in breadth 

 entire or serrated or variously and regularly lobed or pinna- 

 tifid at the margin most so at the base, the lobes obtuse 

 serrated, veins very patent fasciculate pinnate the branches 

 uniting with those of the opposite fascicle (as in Nephro- 

 diuni, Pr., among Aspidiea), sori copious on the veinlets 

 rather short linear decussate often diplazioid and at length 

 confluent, involucres narrow brown membranous, costse be- 

 neath often squamuloso-furfuraceous. — Pr. Rel. Hccmk. i. 2^-

* I am aware that Mr. Moore considers Mr. J. Smith's Stenosemia aurita (no 

 Ste)iosemia, certainly) to be the plant I'resl had in view for his Digrammaria 

 ambigua ; for he says, " there can bo no doubt, from PresFs figure and descrip- 

 tion, that this is the plant he intended to call Digrammaria, but all his synonyms 

 are erroneous." But Presl was surely too acute a pteridologist to commit such 

 an error, and to give two figures with strongly serrated margins (as in the 

 plant before us) to the lobes, while those of J. Smith's Stenosemia are quite 

 entire. Indeed, as far as I know, this plant is exclusively a discovery of Mr. 

 Cuming; and, as such, Presl describes it most accurately in his ' Epimelia 

 Botanica' (quoted by Mr. Moore), under the name of Heterogonium aspidioides. 

 That Presl's Digrammaria is generically identical with Asplenium (or Anisogonium) 

 decussatum, there cannot he the smallest question.
