1882—83] BOTANICAL CORRESPONDENCE. 397 



To Alfred Fryer, Esq. 



Cambridge, Oct. 21, 1882. 



My dear Sir, — Many thanks for the specimen of Btipleurum 

 tenuissimum from Sutton. I have no record of its growing inland 

 since the time of T. Martyn, or other than those recorded in the 

 *'Camb. Flora," p. 96. Have you a specimen to give me of the 

 supposed Agrostis setacea ? I think you sent one, but I cannot find 

 it. I believe that it is the true plant, and a very singular extension 

 of range, and very peculiar place for it. I presume that the Aster 

 and this BupUumm are remnants of an old tidal flora, before the 

 erection of Denver sluices. -Yours very truly, Charles C. Babington. 



To the same. 



Cambridge, Nov. 1, 1882. 



My dear Sir, — I have been looking at your Ardia from Sutton. 

 There seem to be two, but with only one label: A. intermedium = 

 A. puhens (Bab.). A. majus subtomentosum = A. tomentosiim (Bab. ). The 

 grass from Mepal is Serrafalcus commutatus. The other must I think 

 be Agrostis setacea, but it is a very remarkable locality for it. — 

 Yours truly, Charles C. Babington. 



To the same. 



Cambridge, Feb. 14, 1883. 



My dear Sir, — I am glad to learn that you have found Scirpus 

 uniglumis in this county, and hope that you will again be able to 

 gather it this year. I hardly like to take your specimen, but hope 

 to have some bits for our Herbarium when you again find it. — Yours 

 very truly, Charles C. Babington. 



To Frederick Townsend, Esq. 



Cambridge, March 31, 1883. 



Dear Townsend, — I am very much obliged to you for a copy of 

 your "Hants Flora" recently received. I congratulate you upon 

 its publication ; it is admirable. I have gone through it with care, 

 and see many points of great interest, and which will require my 

 attention. I do not well understand about the Orchis inatrnata. Do 

 you think that there are three plants in this country, and that the 

 true incarnata is different from what we have called so in the past ? 

 I confess that I do not see any real points of distinction between 

 C. B. Clarke's and our plant. It seems to be a very variable plant 

 in colour, and there really to me seems to be next to no other 

 difference between them. I presume that you have only Clarke's 

 plant in Hampshire, and suppose that we have only the other here.
