458 Dr. R. C. Alexander’s Account of a Botanical 
Allioni, specimens of which from its station there are in Mr. 
Rainer’s herbarium in Gratz. The Vienna An. Pulsatilla is 
not very different. Indeed botanists are inclined to consider it 
a transition form. The flower is nodding, like Pulsatilla, and the 
leaves are those of the A. Halleri, to which I have myself no 
doubt that it properly belongs. The Potentilla cinerea is another 
questionable plant. Many maintain that there is no difference 
between it, the P. opaca and P. verna, more than arises from 
situation. The cimerea inclosed with this was gathered in a 
wood on a limestone soil, where the forest was burnt some years 
ago, and consisting chiefly of charcoal and ashes. It was with 
the A. Halleri. Foreign botanists who see only the extreme forms 
may find it very easy to distinguish these Potentillas and Ane- 
mones, when collected in their herbaria from distant countries. 
Here on the spot where they grow I find that I cannot. The 
Primula veris, L., appears here as a pure P. officinalis, elatior, 
and acaulis, but between them are transition forms, e/atior with 
radical peduncles all round the scape, and on sloping meadows the 
officinalis is seen to pass gradually into the e/atior in descending 
from above to the moister ground below. Trattinick was quite 
in the right to make one species of it in reference to the Austrian 
flora. : 
The Potentilla sent as micrantha is the breviscapa, Vest. The 
P. Fragariastrum with caudiculi repentes is not found here; but 
this form, the micrantha, far from being confined to the Donati, 
grows on several hills near Gratz, and becoming more abundant 
towards the south, is found in all the woods on the north side of 
the hills in Lower Styria, and I have seen specimens of it in 
herbaria from Agram, and from the Banat in Hungary, sent as 
the Fragariastrum. It appears to me that there is im all genera 
in these countries less tendency to spread by caudiculi than im 
England. Bohemian botanists, Tausch and Co., who live m a 
country where there is very little variety of climate and situation, 
seem incapable of conceiving the versatility of plants in accom- 
modating themselves to circumstances. A more remarkable 
instance of this quality is seen in the Moehringia, which on hot 
dry limestone rocks is M. Pone, and in the crevices and under 
the shadow of bushes WM. muscosa. In ravines which are con- 
stantly damp and shady I have remarked the same transition of 
M. trinervia into M. heterophylla. A very careful and excellent 
botanist, Mr. Zehentner, has collected transition forms with as 
much care as others throw them away, and among Arenarias, 
Campanulas, Primulas and other genera, shown that a great 
number of so-called species are only varieties. - 
On the 2nd of May I set out on my journey through Lower 
Styria. The unceasing wet weather during the whole of this
