that they should have the distribution of all the 

 specimens. Mosses, however, I continue to receive 

 from him, and some very good ones too. 



I rejoice that the Company have sent you so fine 

 a parcel of Ferns, and I thank you for offering to 

 lay by some for me. The little Darea I am quite 

 delighted with ; I had previously picked a wretched 

 bit of a barren frond from among some mosses, and 

 admired its beauty. Your specimen I should like 

 to figure in my Exotic Flora, if you have no objec- 

 tion. I wish a fern-like plant I inclose for you may 

 please you half as much as the Darea has done me; 

 and pray give me your opinion of it : it is an aqua- 

 tic from Guiana, and is found in no other state than 

 what you see. It cannot, I think, according to your 

 character of the Order Filices, really belong to it : 

 with the general aspect of the fructification of a 

 Pteris, there is no ring to the capsules. It cannot 

 be one of the Hydropterides of Willd., because 

 they have the fructification among the roots. At 

 any rate, I think I cannot be wrong in forming a 

 new genus of it, which I am anxious to dedicate to 

 its discoverer Mr. Parker. Can the East Indian 

 Pteris thalictroides (which I have never seen,) belong 

 to the same genus ? or Beauvois' Pteris cornuta ? 

 which you observe comes near the Pteris thalic- 

 troides-, but which again, if Beauvois has represented 

 the fruit correctly, must be widely different. 



It would make me very happy if I could think 

 that I had other plants that would be worth your 

 acceptance. I am increasing my foreign correspon- 

 dence, and have one most excellent contributor in
