The Angiopteris indica of Desvaux we have quoted as a synonym to the present species with 

 mark of doubt. All the character given is u frondibus pinnatis, pinnis lanceolatis :" and the obse 



vation is added, that it is easily distinguished from the already known sp 



t( 



point 



diforme-lanceoleer Our specimens are never cordiform at the base of the pinnules, but are generally 



obtuse, sometimes 



From Dr. Wallich again we have a plant marked " Angiopteris, vix ab A. crassipeda, Wall 



diversar We are unacquaintcd with the crassipeda of Wallich ; but of the plant just mentioned 

 except in its pinnules being narrower and considerably more attenuated than the figurc here given 

 we do not see how it differs from A. erecta. Our Sylhet specimen exactly accords with Mr. Men- 

 zies' from Otaheite.
