 margine in sicco recurvati; lobi maximi ^U—\^U cm. longi, 2—4 mm. lati; 

 lobi fertiles quam stériles breviores et angustiores; venae usque ad 8— 11 

 utrinque, simplices vel interdum furcatae; venae infimae anastomosantes, 

 plantarum ittajorum sequentes apicibus saepe breviter contiguae vel in sinu 

 confluentes. Sori saepe venas omîtes occupantes, marginem quam costulam 

 magis approximati; indusium firmum, persistens, brunneum. breviter pube-

This species is represented in BuNNEMElJER's collection by 3 numbers. 

 The largest spécimen, destitute of its rhizome but with the most distinctly 

 recognizable characteristics, has the pinnae somewhat dimorphous, i. e. the 

 barren pinnae are more approximate, somewhat shorter and broader and 

 shorter-acuminate than the fertile ones. with the lobes doser; the smaller 

 spécimens hâve an erected rhizome, the characteristics less conspicuous, 

 and the barren and fertile pinnae less unequal in shape and dimensions. — 

 No. 9022 is the largest spécimen.
