9. HYMENOPHYLLTJM, Sm. 



Son marginal : indusium dorsally 2-lipped : tube short, or none : column included, rarely 

 exserted, inserted at the summit of a simple or shortly 2-fid veinlet, fertile to the summit 

 or naked below. — Habit of Trichomanes ; leaves mostly divided and petioled, scattered 

 along a fliform rhizome, turning usually brown in drying ; segments with a simple vein. 



I omit several West Indian species of Hymenophyllvm and a few of Trichomanes, named 

 by V. d. Bosch upon the same materials as I had before me, and published lately after his 

 death (Nederl. Kruidk. Arch. 1863) ; for from the descriptions they are apparently not well 

 founded.
