Notes on a Botanical Tour hi Germany.

On the 6th, I again rambled in the woods without adding much to 

 my former observations. Thesium intermedimn of Koch, is very 

 common along the Rhine, and is, I believe, what we in England call 

 T. linophyllum. I here added T. pratense, which differs very dis- 

 tinctly both in the calyx of the fruit, and in the root. Cystea fragilis 

 and Polypodium Dryopteris are common, but I was surprised to meet 

 wdth P. Phegopteris on the dry banks. I followed a little brawling 

 stream down to the valley beyond Hardenburg, but it gave me 

 nothing. Such a brook would have had more interest in England. 

 At Hardenburg there are some very fine ruins of a noble castle. Tetra- 

 gonolobus siliquosus was growing on some boggy ground in another 

 place. I walked on the 7th as far as Maxdorf, a village nearly half 

 way to Mannheim : I had been shown, on a former occasion, a mea- 

 dow full of Dianthus superbus and Gentiana Pneumonanthe, and I 

 was desirous of seeing if it would not yield something at an earlier 

 season. I found there Gentiana utriculosa and Polygala amara. A 

 little nearer to Diirkheim grows Carex hornschuchiana. Koch, in 

 his 'Taschenbuch,' seems to have given up the distinction of the 

 roots between this and C. fulva, and to depend on other characters, 

 which, however, are not very satisfactory ; the principal being the 

 comparative length of the sheathing leaves. I did not see on the 

 hills at Diirkheim, either Trifolium alpestre or montanum, both of 

 which are common hill-plants further down the Rhine, but they both 

 appear in this low sandy district, as does also Arnica montana. 



After leaving Diirkheim, I botanized at Heidelberg, on the 10th 

 and 11th. The immediate neighbourhood is not rich. I gathered 

 Chaerophyllum aureum and Thesium montanum, under the direction 

 of Professor Bischoff. Spiraea Aruncus is common in the woods, and 

 Bromus inermis by the way side. On the 12th, I had a walk to 

 Heilbronn, on the " hunter sandstein," east of the town. A little cliff 

 separates the vineyards from the woodland. It seems as if some beds 

 of a schistose nature formed a useful soil for the vines, and these 

 being dug out, have left a perpendicular cliff : all below is vineyard, 

 all above thicket. We havie therefore none of those ambiguous banks 

 between the two, which often afford such favourable situations. I got 

 Iris sambucina (plentiful in some places on the banks between the
