C, ditto, still more greatly enlarged, to show the loose cellular structure of the 
frond. D, longitudinal section of the sorus magnified. E, theca, with trans- 
verse ring. F, spores. 
All the species of this beautiful genus, amounting to forty -six in number, are 
very cellular and tender, their fruit attached to the midrib of a lobe, as in the 
last genus, but here the receptacle is one-valved, and the midrib not terminated 
by the thecae, and confined within the receptacle, but projecting much beyond it, 
and like a hair in appearance. We have but one species, and that very rare.
