My dear Sir

I have just heard of another opportunity 
of sending to New York by a vessel going directly 
from the Clyde, & I lose no time in making 
up another packet of plants for you, principally 
of Exotic Cryptogamic subjects, many of them 
of the greatest rarity, & such as I trust will
give you pleasure. I enclose likewise the 
memoranda I made while examining your interesting 
cryptogamic plants & I shall here add 
some that I drew up whilst looking over your 
ferns.

Aspidium rufidulum is unquestionably the 
same as Woodsia ilvensis (as is likewise Dicksonia 
[crossed out: pubescens] [added: pilosiuscula [Dicksonia pilosiuscula]]  [Oh.?] & Aspidium punctilobum).

You send a curious ferm as probably a new 
Woodsia. Although it comes very near Woodsia
I think its essential character is different. It has 
an Involucrum* or Indusium primum sphaericum
demum in laxinias 5-6, irregulares, patentes, dentatas
dehiscens, & capsulae sessiles. Now the character 
of Woodsia is to have "involucrum membranaceum
