Exceedingly variable. L. tenera Dry. is a lax, thin, 
freely bipinnate or even tripinnate form with narrow or 
forked pinnules. Simply pinnate forms are common. 
L. flabellulata var. gigantea Hooker, is a form with few 
pinnae, the lower ones acuminate, and only the lowest 
ones pinnate; there is nothing in the diagnosis of 
L. gomphophylla Baker, by which I can distinguish it 
from this form. Some forms are very near Schizoloma 
heterophylhm. 
27 . ODONTOSORIA (Presl.) Fee. 
O. chinensis (L.) J. Sm.
