246 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
C. helvola^ Blytt. {curta x lagopina.) Ref. No. 2980. N. corrie 
of Lochnagar, at 3,300 feet, v.-c. 92, S. Aberdeen, 21st July 1906. 
This station is lower down than the original one, and at some dis- 
tance from it ; C. lagopina grows within 30 yards, and C. curta also 
occurs on the mountain, though we did not come across it close by. 
Herr Kiikenthal writes of both our gatherings : — “ Carex canescetis 
X lagopina^ very characteristic.” In the other locality it was con- 
siderably taller and more developed, the snow having melted longer 
there. — Edward S. Marshall and W. A. Shoolbred. 
C. alpina, Swartz. = C. Halleri, Gunn. In turfy places, at an 
elevation of 3,000 — 3,200 feet on Ben Heasgarnich, Mid. Perth, 
a much greater elevation than in Glen Fiagh, Forfar. August 1906. 
— G. Claridge Druce. 
C. acuta, L. Groby Pool, Leics., 3rd June 1906. — W. Bell. 
C. Hudsonii, Ar. Benn, C. stricta. Good. Twyford Water 
Meadows, near Winchester, May 1906. Teste Kiikenthal. Sent 
on account of its rarity in Hants. It is quite a frequent plant in the 
water meadows near Winchester, but is unknown elsewhere in the 
county. — A. B. Jackson. “ If correct, this is very far from charac- 
teristic ] the important character at the base of the stems is not 
shown in my specimens. The facies that of a tall C. Goodenowii ; 
it may be a hybrid, but the material is inadequate.” — E. S. Mar- 
shall. “ I doubt if this is right. Rather young to decide, but it 
looks to me like C. acuta X Goodenowii.” — E. F. L. “ These speci- 
mens are inferior to those sent up and reported on in Rep. for 1898, 
p. 591, but I think they are the true plant; my example exhibits 
sparingly the fibrous structure towards the base of the stem. Surely 
the correct name is C. elata. All. — W. R. L. 
C. aquatilis, Wahl., forma. Near the Spittal of Glen Shee, 
v.-c. 89. E. Perth. Ref No. 2988. loth July 1906. “ Is towards 
var. virescens. And. ; but in that the glumes are half the length of 
the fruit, arranged very symmetrically ; but it is not quite type.” 
Ar. Bennett in “ Litt.’ — Edward S. Marshall and W. A. Shool- 
bred. 
C. aquatilis X Goodenowii. No. 2989. In a small swamp near 
the Spittal of Glen Shee, v.-c. 89, E. Perth ; mixed with C. aquatilis, 
and with the other parent close at hand. Fairly intermediate, and 
apparently sterile ; narrower-leaved and more glaucous than the 
aquatilis among which it mostly grew. — Edward S. Marshall and 
W. A. Shoolbred. 
C. Goodenowii \ rigida. Bog, near the top of Lochnagar at 
3,500 feet. No. 2982. 27th July 1906. Determined by Htrr 
Kukenthal.— Edward S. Marshall.
