but no specimens, I could not do otherwise than accept the determination. He 

 now regards my plants as distinct. Judging by tbe description, the two species

GLEICHENIA 8m. 



Gleichenia dolosa Copel. nom. nov. (Dicranopteris dolosa Copeland in Perkins's 

 Fragmenta Fl. Philip. (1905) 193.) ' 



Gleichenia crassifolia (Presl) Copel. (Mertensia crassifolia Presl in Fpiin. 

 Bot. p. 23, Tab. 13.) 

 This has been treated as a form of G. linearis, but seems to me to have very 

 sufficient specific characters. Our specimens are from Mount Apo, Mindanao; 

 Copeland 1100, 1458, Be Yore and Hoover 342.
