vineyards, just below the woods), and Rosa gallica sparingly; Crepis 

 praemorsa also occurred, but the variety of plants was small. West 

 of the town, my map says that the hills are of limestone, but the 

 forest in that direction is farther off. On going to Nuremberg, 

 Lychnis viscaria shows itself by the road side; and T noticed Berteroa 

 incana, which afterwards became very common. 



On the 15th, I spent some time with Professor Koch, in the 

 botanical garden, which contains a good collection of German plants; 

 and in the afternoon, had a botanical walk with the gardener, whom 

 Koch sent with me, and with Mr. Schnitzlein, a good botanist, and 

 the author of a work with figures to explain the natural orders of 

 plants. Our walk lay chiefly in that part of an extensive forest of 

 pines, which lies to the west of the road to Nuremberg, and which 

 advances to within a mile of Erlangen, and some adjoining moist 

 meadow lands. The soil is everywhere sand. In the woods it is also 

 the moist parts which are most productive. The drier parts are 

 almost covered with Vaccinium Vitis-idaea, now in flower. Our 

 plants were Polygala amara, Sedum villosum, Trifolium hybridum 

 {Koch), Chaerophyllum hirsutum, Hieracium praealtum, var. fallax, 

 Poa sudelica, Carex davalliana and brizoides, and Orchis angustifolia. 

 Orchis latifolia grows in the same places ; and here the eye readily 

 learns to distinguish them : but as I have already observed, their 

 forms must be traced in different localities before we can fully decide 

 as to their specific distinction. In some meadows on the other side 

 of the little river, the next day I gathered Erysimum strictum, under 

 the guidance of Professor Hoffrath Koch, and we saw also plants 

 of Chaerophyllum bulbosum, and Ruraex maximus, but neither of 

 them approaching to flowering. Koch's knowledge of species, and 

 readiness with their minute characteristics, is wonderful ; he seems to 

 have everything of the sort at his finger's ends. He is now publish- 

 ing an enlarged edition of his ' Synopsis,' but I am afraid is rather 

 too ready to multiply the number of species. The sandy hills behind 

 Erlangen offered me Dianthus deltoides, Trifolium spadiceum, Vicia 

 tenuifolia, V. villosa, var. glabra, Lathyrus tuberosus, Pyrola secunda 

 and rotundifolia, Caucalis latifolia, Eriophorum vaginatum. The 

 18th and 19th of June were spent in an excursion to Muggendorf, 

 and I was very sorry when I saw the place, that I had not dedicated 

 to it a longer time. The country is of the Jura limestone, intersected 

 with very narrow rocky valleys, richly adorned with wood, and each 

 watered bv its own bright beautiful stream.
