stitutino- linear simple sori, analogous to Grammitis, to 

 which the species have been referred by some authors, but 

 their entirely distinct habit sho\ys that they possess no 

 direct affinity with Grammitis, as here defined. They have 

 also been referred to Gyranogramma, under which genus 

 they stand in the " Species Filicum." 



The genus consists of about ten known species, of which 

 six are natives of the West Indies and Tropical America, 

 the other four being natives of Tropical Africa, India, Java, 

 and Japan, i. iotta having a very wide range, being found 

 in the Azores, Madeira, Western and South Africa, Ceylon,
