164 THE .TOUJIXAL OF EOTATs^Y « 



long appressed hairs. Flowers 3^ellow-green or yellowish, 3"5-4 mm. 

 broad ; urceoles with short usually somewhat rounded base, 8- 

 8*5 mm. long, glabrous or in the lowest flowers with solitary or few 

 long erect spreading hairs ; calyx- and epicalyx-segments of the lower 

 or lowest flowers with some apical hairs, those of the upper flowers 

 glabrous. [Damp ])hices or new springs : Greenland ; Iceland ; 

 Scandinavia; Finland; N.E.Russia.] 



There should he no difliculty in distinguishing this from its allies. 

 A.JlIicaitlis Baser, the northern relative of A. minor Huds., may, in 

 some of its forms, have a distribution of hairs very similar, but the 

 hairs are widesj)reading on stem and petiole, and it is a smaller 

 plant than the specimens of A. glomerulans which I have seen. 



The flrst British specimen noticed was brought to me in 1917 l)y 

 Mr. lioffey among a parcel of Scotch plants, labelled " Glen Eunaeh, 

 Inverness-sh., Aug. 1916." I immediately named it as probably 

 A. glomeralcDis, but had no specimens of that specie-s Avith which to 

 compare it. Mr. C. E. Salmon has since kindly compared it with 

 specimens in his herbarium sent him b}^ Mr. Lindberg, and confirms 

 my identification. 



Examination of the herbarium of the late E. S. Marshall (at 

 Cambridge) disclosed a second specimen labelled : " Kef. no. 3885, 

 see Wats. E. C. liep. 1913. Abundant (from al)out 1800 to nearly 

 3000 feet) by a streamlet on the south side of Ben Lawers, Sept. 4, 

 1913 .... mucli more plentiful than our ordinary form of A. 

 alpestris Schmidt, and easily separable from it, when growing. 

 Dr. C. E. Moss pointed it out as the plant discovered by Ostenfeld 

 (August 1911) in this station, and named by him as ^. acufidens 

 Baser. Proved, by cultivation, to be only A. alpestris, E, H. M. 

 1918." This specimen puzzled me, since I remembered agreeing that 

 the specimen sent under this number to the National Herbarium was 

 A. alpestris. On the next sheet I found it to contain further speci- 

 mens of 3885 with the same locality-label, and a similar observation 

 about A. acntidens, except that " cultivation proved this to be good 

 A. alpestris I '^ This sheet Avas indeed A. alpestris: evidently 

 Marshall did not se])arate the two in the field as clearly as he 

 imagined. On this sheet he notes *' it was associated with ordinary 

 A. alpestris Schmidt .... unusually large." As these specimens 

 are small for A. alpestris and smaller than that of A. glomerulans, 

 the latter note presumably refers to the other sheet. 



Careful search will ])robably show that this form is fairly widely 

 spread in Scotland. The species grows in Iceland and has a wide 

 distribution, whereas the remaining segregate species which occur in 

 Scandinavia are not so widespread, and are less likely to occur here. 



Since writing the above, I have found among some duplicates 

 received at the National Herbarium from the South London Botanical 

 Institute a specimen of another of these small species, A. pastoral is 

 Buser. This is the plant which must retain the name vulgaris in 

 the most restricted sense, as A. vulgaris L. emend., "Buser in 

 Dorfler, Herb. Norm. 3633 (1898)" (Lindberg). This is a plant 

 which at first sight looks like A. pratensis, having dense spreading
