1877] BOTANICAL CORRESPONDENCE. 381 



Sieracium Dewari. Where is this described? 



JS. pratense. I have this growing, by Mr. Christie's kindness. It seems 

 the true plant, and the H. duhium of the " Manual," edition 7. 



Crepis nicaeensis. Has not this been introduced with seed ? 



Carduus tetosus. No. It is a plant which I have seen several times, and 

 which appears in the " Manual," edition 1, as /3 latifolius, but I have long 

 since considered it unworthy of distinction, even as a variety. 



Rumex Sydrolapatlium var. from Mr. Varenne. Is not this H. maximusl 

 That is a plant I know very little about. 



Trichonema Columnae. I am glad to find that this is still to be found. 

 I had been told that it was extirpated. 



Zannichellia polycarpa from Belfast. Very interesting. Is Warren's 

 Sussex plant the same ? 



Chara aspera. I cannot believe it. Surely it is only C. hispida.

Dear Sir, — I hope to be again at home some day next week. I 

 thank you very much for the information contained in your letter. 

 Living plants of the Limosella would be of no use to me, as I fear 

 that I could do nothing with them. Have they flowered 1 If so, 

 please to dry one or two good specimens for me. It would be as 

 well to keep plants of the seedling willows transplanted, to see into 

 what they will grow. The cleaning out of lodes and ditches is an 

 admirable time to get plants which have been recently lost to the 

 country. I hope that you are keeping a complete list of the plants 

 found in your district, as it may be of much use in due time. 

 Yours, and the adjoining fen districts have only been partially 

 worked, and I am therefore exceedingly glad that a botanist who 

 lives in one of them has taken the making of a careful list in hand. 

 You have been most successful hitherto. I should like to see you 

 at Cambridge, on some day that may be convenient to you. — Yours 

 very truly, Charles C. Babington. 



Please also to keep Laduca Scariola for me, and any other 

 interesting plants. I shall be most thankful for them for our 

 herbarium. 



To Henry Groves, Esq. 



Cambridge, Oct., 1877. 



My dear Sir, — The Chara fragifera (Duv.) is described for the 

 first time in the "Bull. Bot. France " VL 187. It has been detected 

 by Mr. Ralfs, near Penzance, and is apparently not uncommon in 

 the western part of Cornwall. It is a beautiful plant. As I have 

 only just returned home after an unusually prolonged absence, I 

 have not examined your Charae sent on August 16. I will do so 

 now very soon, but I find an accumulation of work to be done now. 

 Your plant from Birkinhirst (?) is certainly very like the fragifera, 

 but requires a careful examination. The very curious root-bulbs of 

 fragifera are not these. — Yours very truly, Charles C. Babington.
