We cannot say whether in a living state the margin of this Fern is involute : to us it appears to 

 be tbe effect of drying, as we know to be equally the case in the Polypodium pertusum. There is 

 too> on the surface of the present plant, as seen in the herbarium, a rugose or wrinkled appearance, 

 the consequence of the drying and shrinking of the parenchymatous substance beneath the epi- 

 dermis.

Our plants were gathered by Dr. Wallich in Nepal, and were sent to us with the name of Gram- 

 niitis ? plantaginea ; whilst Dr. Hamilton seems previously to have given the MSS. specific name of 

 involutum, which is adopted by Mr. Don. Again, we have received specimens from the Honourable 

 the East India Company, bearing the name " Grammitis flavescens.
