Other name:	Cyperaceae: Carex elata All. ("Tufted-sedge") det. Almquist "Carex stricta, var.-probably" Dr. Almquist in litt. to A.Bennett, on the same plant colld 21.6.1885, bearing, I believe Mr Bennett's number 138. (My number 211)
Filed in taxon folder:	Cyperaceae: Carex elata All. ("Tufted-sedge")
Collected by:	Mr William Hadden Beeby
Collection date:	11/7/1886
Locality:	Great Britain, VC17 Surrey, Hedgecourt Lake, TQ3540, The plant forms large, dense, tufts; but I can detect no fibrillae at the base of stem. The plant is usually submerged, + Mr Alfred Fryer thinks that when this is the case, the fibrillae are often absent. If the further specimens enable a definite opinion

But then, most memorably [noticeably], although it is growing in tufts, fibrils are lacking, which I have seen only in solitary specimens.

N.B. reporting of the edit history is currently fairly unclear and misleading. Most edits made to specimens appear as a pair of 'add' and 'delete' entries, which may not be together in the list. There are also often 'minor' edits, which are made automatically (rather than due to user activity), for example to merge synonym names.

Can anyone translate the Latin text or is the base of the sheet the translation? This is another potential hybrid that may be confirmed from an examination of the actual specimen.

The second image with its text is not easily accessible at the moment. Latin scholars should look HERE!
