green; nut brown, flat, orbicular, punctulate. From C. acuta , which it 
approaches in most respects, it is at once distinguishable by its 
channelled (semi-cylindric) leaves. It was found abundantly for twenty 
to thirty yards along a ditch, growing in rich peaty soil. — E. S. 
Marshall. Also sent by W. A. Shoolbred. “When Mr. Marshall 
first showed me a specimen of this gathering, it appeared to me 
identical with a form I have collected from localities in Hants and 
Dorset, and on account of its variation from C. Goodenowii in the 
direction of C. acuta , I have had it for some years under the name of 
C. Goodenowii, , var. subacuta , ined. The suggestion by Pfarrer 
Kiikenthal that the Altnaharra sedge is C. acuta x Goodenowii led me 
to re-examine my own series in this light, and as all the Hants and 
Dorset plants appear to be sterile, I feel no difficulty in accepting this 
solution for them. But Messrs Marshall and Shoolbred’s C. acuta x 
Goodenoivii is not sterile. The fruit is fortunately almost mature and 
is perfectly well formed. I am not aware of any fertile Carex hybrid, 
and in spite of the great likeness between these specimens and my 
own, enough at least for two forms of the same hybrid, I find difficulty 
in calling this fruiting sedge C. acuta x Goodenowii. The only specimen 
in my series of C. Goodenowii , var. subacuta , mihi, which is clearly 
fertile, is from the Bog of Lynn, Westmeath; but this is a more doubt- 
ful plant, and I do not remember any C. acuta growing with it. A 
Carex sent to the Club by Mr. Druce as C. elata , from Sandhurst, 
Berks, has been placed with my ‘ subacuta ’ forms, and as it appears to 
be sterile, I think it likely to be a hybrid of C. Goodenowii perhaps 
rather with C. Hudsonii , Ar. Benn., than with C. acuta , L.” — E. F. 
Linton. “ It may be well to state that Dr. Lange considers my Sand- 
hurst plant to be C. turfosa , Fries, which most botanists put under 
C. elata.” — G. C. Druce.

C. Goodenoivii , J. Gay, var. elatior (Lang.), f. angustifolia , 
Kiikenthal. Burn near Rhi-tongue, West Sutherland, 26th July 
1897, ref. No. 451. — W. A. Shoolbred; also from E. S. Marshall, 
ref. No. 1938. Named by Pfarrer G. Kiikenthal. “Agrees with J. 
Gay’s example of C. Goodenowii , in 1 Herb. Kew.,’ so far as I, assisted 
by an official, can see.” — C. B. Clarke. 
C. Goodenowii , Gay, var. Marsh near Altnaharra, West Suther- 
land, August 1897, ref. No. 1937. Leaves involute or channelled. 
‘Apparently a stiff form of Carex j micella, Fries.,’ Pfarrer G. 
Kiikenthal, in lit. — E. S. Marshall. Also from W. A. Shoolbred, 
gathered at the same time and place, ref. No. 450. Mr. C. B. 
Clarke also considers it to be var. j uncella.
