150 HISTORY AND GEOGRAPHY OF TREES. “PART Ie 
The modern collections of trees in Germany are too numerous to be men- 
tioned in this work, and we can only, therefore, give the names of those which 
we have been informed are the most complete. 
In Austria there is an excellent collection in the University Botanic Garden 
of Vienna, under the care of Baron Jacquin, chiefly planted within the last 
twenty years, but a part much older. Here the macluras, male and female, 
stand in the open air, but require protection during winter. The salisburia 
here, and those in several other places near Vienna, flower annually ; but they 
are all male plants. On that in the Botanic Garden, Baron Jacquin has had 
the female grafted with scions from Geneva, but they have not yet flowered. 
Laxenburg is more remarkable for native trees than for foreign ones; but there 
are some very large tulip trees, which ripen their seeds every year, and some 
very large purple beeches and weeping willows. There is there an Araucaria 
excélsa, protected during winter by a wooden house, which has attained the 
height of 30 ft. in six or seven years. Baron Jacquin assures us that this is 
one of the finest and most picturesque specimens of this tree that can be 
imagined. In the park there are many fine oaks of the growth of several 
centuries ; and a very comprehensive general collection of trees and shrubs, 
of from ten to forty years’ growth. All these have been planted by, and are 
now under the care of, M. Stephen Rauch, through the exertions of whose 
son, M. Charles Rauch, now head gardener at Rennweg, we have received 
much of the information contained in this section; while another son, M. 
Francis Rauch, now (1835) in London, has drawn from nature the greater 
part of the botanical specimens by which this work is illustrated. In Austria 
Proper there are collections at Bruck on the Leytha, on the borders of Hun- 
gary ; at Dornbach, Prince Schwartzenberg; at Hadersdorf, Baron Loudon (a 
view of whose mansion we have given in the Encyclopedia of Gardening, 
edit. 1835, p. 136. fig. 87.); and at the nurseries of Rosenthal, and Held in 
Vienna. On Kopenzel Berg, a hill in the neighbourhood of Vienna, from 
which there is one of the finest views in Europe, there is a tulip tree 
60 years planted, which has an immense globular spreading head, though only 
45 tt. high. At Bruck, the trees have been chiefly planted within the last eight 
or ten years ; but there are some older specimens well deserving notice; such 
as A‘cer striatum, 18 ft. high in 20 years; Palitrus australis, 18 ft. high in 
30 years; and Fraxinus atrovirens, 18 ft. high in 20 years. At Dornbach 
there is a good collection; but very few trees that have been above 40 years 
planted. At Hadersdorf we observed, in 1814, some fine cypress trees 
planted round the tomb of the great Marshal Loudon, but in the Return 
Paper received they are not mentioned; there is, however, a good collection, 
the most rapidly growing tree of which appears to be that beautiful species of 
elm, U‘lmus effiisa, which, in 20 years, has attained the height of 36 ft. in 
poor sandy soil. The Vienna nurseries, especially that of Rosenthal, contain 
good collections planted within the last 20 years. 
There are collections at Eisenstadt, and other residences, in Hungary, and 
in the botanic garden at Pesth. In Bohemia there are collections at Toeplitz, 
Schonhoff, and other places. 
The following enumeration of the evergreen trees and shrubs, foreign and 
indigenous, which stand the winter at Vienna without protection has been
