Aspleniaceae
Species Description - Rhizomes epiphytic; stipes often nearly equalling the blades, green on upper side, darkish beneath; blades oblong, acuminate, not reduced at base, mostly 5 -12 cm broad, the rhachis green, alate, not proliferous; pinnae thick in texture, bluish-green, opaque, numerous, subsessile, rounded to acute, extremely variable, sometimes almost subentire with a rounded superior auricle, sometimes serrate and acutely auriculate, sometimes pinnately lobed or fully pinnate; veins forked; indusia thickish, whitish.
Distribution and Ecology - Common in the West Indies and in continental North and South America from Mexico to Bolivia and Argentina.
?Poly podium serratum Aublet. Pl. Guiane 2: 972. 1773. Type: French Guiana. Aublet. It will be impossible to place this name unless a tvpe specimen can be located, since the original description is too brief. Mettenius assumed that it was a form of A. auritum. non Asplenium serratum L. 1753.
Asplenium dissectum Gmelin. in L. Syst. Nat., ed. 13. 2 (2): 1302. 1791. non Swartz. 1788.
Type: Based solely on Plumier, Lonchitis dentata, pinnularum Cacumine bissecto. Tract. Fil. Amer. t. 4o.
Asplenium rigidum Swartz, K. Sv. Vetenskapsakad. Handl. 1817: 68. 1817. Type: Villa Rica, Minas Gerais, Freyreis (holotype S, photograph 5780a) .
Asplenium recognitum Kunze, Linnaea 22: 577. 1849. Type: Based on Plumier t. 46, and thus a nomenclatural synonym of A. dissectum Gmelin, non Swartz, of which it may be considered a renaming. Kunze also cited Regnell I. 486, from Brazil, but since he gives no description at all, the species must rest on the description and figure of Plumier cited.
Asplenium sulcatum auctt. non Lamarck.
Type. Jamaica, Swartz (holotype S, photograph 5780). The type is once pinnate, with narrowly lanceolate, long-acuminate (but scarcely caudate) pinnae, these cuneate at base and strongly unequal-sided, the upper margin just serrate except for a superior basal lobe, this lobe elongate and acutish, much more than half free.
