430 CHARLES CARD ALE BABINGTON. [1890 



Armeria v. duriuscula. I think it is. 



JPotamogeton. A very interesting form of natans. 



Ranunculus Drouetii ? No. Can it be triphyllus ? 



R. Baudotii. Good, From Sandwich. 



Polygonum Roberti is I believe undeterminable, and includes bits of 

 several plants, it is doubtless my Rail. 



Arahis petraea v. grandijlora. Has Druce published this anywhere % 

 Carer Jlava -\- pulla. May not this be C lepidocarpal 



Callitriche stagnalis-serpyllifolia is interesting. 



Car. limosa from Kingshouse requires attention. 



Salix Lapponum from Corrie Ardran. I am sorry that I can give no 

 opinion on this. I do not understand the Alpine Salices. 



Betula fj'om Glen Palloch is very like Norwegica, as figured by Keichen- 

 bach, " Icones," xii. 624, a form of carpatica. The scale will not do for inter- 

 media. 



Cochlearia groenlandica. Very curious pouches. 



Hieracium. Many thanks for the beautiful set of these. 



Aira multiculmis. Beautiful. 



Poa Balfour, montana. Tlorets not quite free here, but I think it should 

 be so named. Many thanks for the most valuable set of Hackel's named, 

 specimens. 



Mpilohium Lamyi is still a puzzle to me. 



Mpilobium adnatum is I suppose a synonym for my tetragonum. 



To Henry Groves, Esq. 



Cambridge, March 18, 1890. 

 Dear Mr. Groves, — I am rather fully occupied, but if allowed 

 time, will do what I can with the specimens you think fit to send me, 

 especially with the Rtibi. Please inform me what of them I maj^ 

 retain for my own use. Please also direct the parcel to me at "The 

 Herbarium, Free School Lane, Cambridge," as that will be more con- 

 venient than if it came to my house, more than half-a-mile from the 

 plants. I am very much obliged to you for the copy of your paper 

 upon Chara Nordstedtiana. I have been much pleased to receive several 

 specimens of it, but all from the same place. I found two, one a 

 CJiara and the other a Nitella, at 1700 to 1800 feet at Braemar. Have 

 you had any from there ? I have not yet named them. Shall I 

 send them for you to examine and partially retain ? If I am again 

 at Braemar in September, would you like to have fresh specimens 

 of Characeae from there ? I do not think that there are more than 

 those two. — With my kind regards to your brother, believe me to 

 be, most truly yours, Charles C. Babington. 



To the same. 



Cambridge, April 12, 1890. 



Dear Mr. Groves, — I return the list of the Exchange Club Rubi 

 with such notes as seem to be wanted. I have given much time to 

 them, and have been very much interested. I find amongst the notes 

 so kindly sent to me the enclosed, which I cannot refer to any of the 

 specimens. Can you help me I These notes of Focke and Baker
