37. Dryopteris Anniesii Rosenstock, Hedwigia 46: 118. 1907. — Fig. 7. 



Type from Brasilia, Rio Grande do Sul, Campestre do Seivaes, leg. Jürgens 

 u. Stier nr. 158 (R!). 



A large species; leaf 1 m or more long with numerous, alternate pinnæ, which 

 are up to 20 cm long by 'i'/U — 2'/3 cm broad, the lower ones not or a little short- 

 ened. Segments patent or subfalcate, generally broadest towards the apex, sepa- 

 rated by round, broad sinuses, the lower ones free or nearly so. Veins 12— 15-jugate. 

 Sori numerous subcostular or at least distinctly inframedial, reddish, furnished by 

 a persistent, rather large, reddish, glabrous indusium. Leaf tissue of both sur- 

 faces glabrous, the underside often finely glandular, margins ciliate. — In general 

 habit the species is not unlike D. ctenitis, probably its nearest ally, which it also 

 resembles in the dense tuft of scales at the base of the stipe, its inframedial sori 

 and persistent indusia, but il differs considerably by the structure of the scales; 



soft and clear, not unlike those of D. dcflexa, but 

 their margins are toothed only not long- 

 fimbriated (fig. 3 ''). — Stipe and rachis 

 dark-coloured densely clothed with ad- 

 pressed, darker scales.
