or forked hairs. Head of sporangium glabrous, but its pedicel bears a single 

 simple or furcate hair. — None of the specimens referred hereto shows small short- 

 stalked sterile leaves, which are often to be seen in specimens of Ü. reptans; all 

 leaves from the same rhizome are always uniform, the stipes are stramineous, 

 glabrous. 8 — 15 cm long, slightly scaly below, fasciculated on an erect rhizome, 

 which is rather scaly at the top by glossy, brown, acuminate, stellato-pubescent 

 scales. Larger specimens may be confounded with I), serrulata, but I think, that it 

 always can be distinguished from that species by its more decidedly pubescent rachis 

 and costæ and its rounded lobes. From D. sclerophylla it differs by its fresh-or- 

 dark-green colour, thinner texture and non stellato-pilose surfaces. 



Maxon, believing that P. asplenioides Sw. was founded on Sloane's plate 43 

 fig. 2, quoted by Swartz, reduced Swartz's name to a synonym of 1). serrulata. 

 Granting that Sloane's plate illustrates our D. serrulata rather than D. asplenioides 

 I must say again that Swartz never founded a species on old figures; his P. asple- 

 nioides is founded on specimens collected by himself in Jamaica. A specimen 

 from Herb. Sw. (S), which belongs to the present species, agrees very well with 

 Swartz's description in Fl. Ind. occ. 1659, but unfortunately it is not labelled with 

 certainty by Swartz. 



D. asplenioides varies especially in size and texture, which probably is due 

 to age and outer conditions. It is in its true form apparently confined to Jamaica.

Type from Bermuda (not seen). 



Closely related to 1). asplenioides and the smaller forms difficult to distinguish 

 from that species. Still the pinnæ are generally larger (8 — 10 x 2 cm) and cut 

 more than halfway to the costa. Both surfaces with scattered, whitish, simple or 

 forked hairs, most numerous on the ribs; rachis rather hairy by short stellate 

 hairs and longer, simple ones. Veins 6 — 7-jugate, the lower pair united or more 

 'often running side by side to the sinus, the others very often furcate. Sori 

 medial or supramedial, furnished with a ciliate indusium; hairs of indusium 

 simple, or, rarely forked. Sporangia without hair on the pedicel. The scales of 

 the oblique rhizome are stellato-pilose throughout; they are not so large as shown 

 in the plate quoted, which otherwise illustrate the species very well.
