372 NOTES ON THE FLORA OF HOLSTEIN. 
Leonurus Cardiaca. In considerable abundance on roadsides, 
rubbish heaps, hedges, etc.,’ round Schenefeld. 
Lycopus europeus. Common in the ditches everywhere. 
Lysimachia vulgaris. Pretty abundant in the wet thickets and 
marshes on the Elbe, below Blankenese. ZL. nemorum and 
Nummularia, in the woods round Pinneberg and Rellingen. 
Lythrum Salicaria. Exeeedingly common on all the Elbe 
marshes and islands, besides ditches and marshes every- 
where. Its abundance gives a deep red tinge to all the 
Elbe islands, when looked at from the deck of a steamer, 
for example. 
Medicago sativa. I met with only a few plants on the gravel 
banks behind Blankenese. Koch mentions that it is per- 
haps originally from Spain, and naturalized, but also cer- 
tainly native in Germany. 
Melilotus officinalis is rather common in the Elbe marshes and 
thickets below Blankenese. 
Mentha sylvestris. Common in the same locality. 
Menyanthes trifoliata is very common in all the bogs and pools. 
I merely introduce it here for the purpose of mentioning 
that its leaves (along with Tormentil-root and many other 
astringent vegetables) are much used in the preparation of 
various bitters, which seem to be much relished on the 
Continent. Bitters were unusually fashionable, during my 
visit, on account of the prevalence of the cholera, which was 
then raging fiercely in Hamburg and Liibeck, and over a 
considerable part of Germany: this being one of the many 
thousand nostrums the Germans habitually swallow as pre- 
ventive remedies. One kind, called familiarly in Altona 
“Cholera Schnaps,” contains brandy, ether, Buckbean, and 
Tormentil: another, “ Pfeffermint Schnaps,” contains Es- 
sence of Peppermint, which is a very popular remedy in 
cholera. 
Cinothera muricata grows abundantly on the Blankenese gravel 
hills. 
Ononis spinosa. Common in the above station. 
Nasturtium sylvestre abounds in the Elbe marshes below Blan- 
kenese. 
Nuphar lutea. Plentiful on all the larger pools, lakes, dams, ete. 
(Enanthe fistulosa. 1 found only a few specimens in a ditch near
