A, pinnule of Trichomanes brevisetum. B, portion ofdittowith fruit, enlarged. 
C, ditto, still more greatly enlarged, to show the loose cellular structure of the 
jrond. 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 -valued, and the midrib not terminated 
y . ec< f» 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.
