Davallia subdissecta, v. A. v. R., Bull. Btz., 1916, XXUl, 11. 



Near D. dissecta J. Sm. — Rhizome scales squarrose, narrowly long- 

 linear-subulate from a suddenly dilated, round, peltate, adpressed base, 

 ciliate; soriferous lobules proportionally broader at the base, retuse at 

 the apex with mostly 2 (sometimes 3) teeth unequal in length; indusium 

 semicylindrical, proportionally broadly winged by the edges of the lobules, 

 the apex + reaching the sinus between the teeth. 



Forma typica: Outer tooth of the soriferous lobules sometimes elongated 

 to a short, straight horn; indusium 2 — 3 X as long as broad. — yava 

 {Mt. Cede, J. G. Rallier No. 671). 



Var. elegantior: Lobuli soriferi dente exteriore saepe valde elongate, 

 incurvato, cormformi, dente interiore interdum elongato; indusium 3— 4X 

 longius quam latum, infra apicem saepe paullo angustatum. — Java {Mt.
