28 . DRYOPTERIS INAEQUAL1S (Schl.) O. Ktze. 
Plate 18. Nat. size, b Sorus, enlarged. 
Main rhizome procumbent even at the crown, and not so 
scaly as in last species, several inches long, and often with 
slender rhizomes a foot long proceeding from it. Frond firmly 
herbaceous, glabrous, three-pinnatifid, ovate-lanceolate, one 
to one and a half feet long, six to eight inches broad, with 
a paleaceous stipe one foot long, and with scattered scales 
along the rachis and mid-rib. Lower pinnae not larger or 
rather less than those above, and almost equal-sided. Pinnae 
all pointed from a wide base, divided below to the channelled 
rachis into ovate- oblong, obtuse, lobed or pinnatifid pinnae, 
which are sharply serrated, and have a rounded or shortly 
cuneate base. Sori very abundant ; involucre persistent, not 
hairy. 
As stated under D. elongata, this species and that are very 
closely allied, and if really distinct, often confused. It also 
approaches very closely some of the forms of the European 
D. spinulosum (Miill.) O. Ktze, and all the specimens so named 
in the Colonial herbaria are this plant. Baker {Syn. Fil. 2 76) 
mentions N. spinulosum Desv. as found “sparingly in Cape 
Colony,” and Kuhn quotes Drege’s locality on P. and R.’s 
authority, but I have seen no specimens which would indicate
