﻿140 13. DIPLAZIOPSIS. 



Rhizome short. Stipes not articulate to the rhizome. Fronds simply 

 pinnate; veins anastomosing, forming 2 — 3 rows of + hexagonal areolae near 

 the margin. Hk. Bk., Syn. Fil., tab. IV, fig. 39; Diels, in Engl, k Prantl. 

 Nat. Pfl.Fam., I*, fig. 121, E. {Allanlodia). 



Paleotropical.

Rhizome erect, covered with lanceolate scales. Stipes 15 — 35 c.M. long, 

 slightly scaly at the base. Fronds oblong-lanceolate, 50 — 100 c.M. long, 18 — 35 

 c.M. broad, pinnate. Pinnae sessile or short-stalked, linear, the apex 

 acuminate, the base truncate, the longest ones 10 — 15 c.M. long, 2 — 4 cM. 

 broad, the margin entire or irregularly crenate. Texture membranaceo-her- 

 baceous; surfaces naked; veins anastomosing, forming several rows of long and 

 short, nearly hexagonal areolae near the margin. Sori confined to the anterior 

 veinlets of the primary forkings. 



North. India, Australasia, Polynesia.

Sori submarginal. tei*minal on the veins, ± globose; indusium inferior, 

 united with the margin of the frond to form a distinctly cup-shaped, mem- 

 branaceous involucre to the sorus, the top open, sometimes slightly 2-lipped 

 or 2-valved. 



Rhizome mostly creeping, often hairy, rarely erect or arborescent. Stipes not 

 articulate to the rhizome or the caudex. Fronds rather large, at least 2-pin- 

 nate, superficially resembling Dicksonia; veins free. Hk. Bk., Syn. Fil., tab.
