Type from Brazil, leg. (PoHL?) (not seen, but there is no doubt of the right 
interpretation). 
A very distinct species of a somewhat doubtful position, often confounded with 
the less divided forms of D. connexa. It differs, however, from that species as well 
as from all other species of this group by the absence of articulated, rufous hairs 
(Cienitis-hairs) on the costules and coste above. Besides it is well-marked by its 
thick, papyraceous texture and brownish colour when dried, and by its little cut 
lamina that is bipinnatifid or bipinnate only. — Basal scales rather soft, brown, 
linear, often very narrow, flexible, sharply and retrorsely dentate; similar smaller, 
hairlike scales are to be found on the rachis and cost beneath. Upper surface 
perfectly glabrous, the margins ciliate, the under surface generally glabrous, rarely with 
scattered, articulated hairs or very finely puberulous especially on the coste (f.- 
Fischeriana Regel). Veins pinnate in the lobes, immersed, simple, fureate or again 
pinnated, very oblique, nearly or quite reaching the margin. Sori slightly immersed, 
in 1—3 rows on each side of the midvein of the segment, rather small, often 
yellowish. Indusium none. 
D. grandis is very variable in size and cutting. Most authors distinguish two 
‘species or varieties, viz: 
1. (P. macropterum Kifs.). Leaf bipinnatifid or bipinnate below only. -Pinne 
10—20 cm long, 3—4 cm broad, acuminate, incised about two-thirds of the way 
down into arcuate, obtuse, entire segments, about 1 cm broad. Lateral veins simple 
or furcate, the basal ones springing out from the costa and terminating in the leaf- 
_ tissue below the sinus. Sori in 2—3 rows on each side. 
2. (P. splendidum Klfs.). Much larger, fully bipinnate below, deeply bipinnatifid 
at the middle. Middle pinne 20—30 cm long, 6—8 cm broad, incised nearly to 
the costa into arcuate, obtuse faintly serrulate or crenate segments, 1'/2 cm broad. 
Lateral veins pinnate, 2—3 jugate, the basal ones springing out from the midrib of 
the segment. Sori in 1—3 rows on each side.
