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.

Label difficult to read and possibly in German.

I think the location is "Im Gröbenbach bei Gröbenzell" (Bavaria) where Dr Kurt Harz found this plant on 26 Sept 1921. There is even an image of his sheet!

Improving the image:



..I think the label says "Im Gröbenbach bei Gröbenzell Leg. Dr. Kurt Harz".

(see above links to message board).

I was surprised that the 'G' or 'f' (at the beginnining of Harz and the end of Grobenbach) could be an 'H'. That might help in deciphering some of these labels (eg Dr Ganz), is it definitely so?

[Roger Horton]

For some reason Anders Thorup, a Danish mathematician, has images of German Gothic handwritten alphabets on the web, four in all, which give an idea of variation in styles: 1, 2, 3, 4.

In addition to 'H h' surprises are: the separation of down-strokes from loops in a, g, q; the unfamiliar shapes of e, k, r etc.; and the fact that u is written like ũ, easily confused with ü.

There is an image of a Harz Mentha aquatica sheet helpfully relabeled with a printed label HERE.

A more relevant image (Potamogeton coloratus "im Gröbenbach bei Gröbenzell", Kurt Harz – 26.09.1921), at Regensburg, is temporally unavailable.
