The western varieties ceftainly will conduct themselves as the related south and 

 middle European. 



It has always been striking to me that here some American trees and shrubs 

 do not bear fruit, i.e. Robinia hispidanie , Maclara aurantiaca , Caprifolium sempervirens , 

 viscosa infrequently, whereas Pseudoacacia bears so plentifully. Likewise with Rubus 

 odoratus the flowers fall off and if one wants to explain this through the warm habitat, 

 then it does not occur with Rubus nutkanus which however stems from a region cooler 

 in summer and which also does not set on any fruit here with us, whereas the far 

 more southerly Liriodendron and Magnolias some years here have germinating-capable 

 seeds, even if the Magnolias do not have as füll fruit-cones as in Italy, but only 

 individual kernels. 



Pinus rigida here has cones and this on the whole is from far warmer regions 

 than Bohemia. Pinus , Paeda , Contorta , Inops, Coulterj , Ponderosa I have not observed 

 in enough old specimens, Insignis and Sabiniana seems to be somewhat sensitive, but 

 not nearly like Pinea, only about like Pinaster which variety, when one has brought it 

 past the first youth stages, has flourished here real well. I have not yet made any 

 tests with australis, Cryptomeria japonica , Wellingtonia gigantea , Thuja gigantea , 

 Sequoja sempervirens, Taxadium distichum , Cunninghamia sinensis , Cedrus Deodara, 

 Mbani, Atlantica. I have brought through successfully in the open thus far. It is 

 remarkable to me when I read in the "Report on Forestry" that in America Pinus 

 silvestris and Larix europaea are cultivated rauch on a large scale. Should not the 

 American larches perform the sarae Services? Perhaps in America the seeds of the 

 native larches are more difficult to obtain than those from Europe. Pinus silvestris 

 certainly seems to grow higher than all East American Pines, with the exception of 

 £trobus, and has a better wood than these. In addition it can endure all inclemencies 

 of the weather, which probably cannot be said of Taeda rigida and even ponderosa and 

 other western varieties in the northern states cannot stand the winter. On the other 

 hand I believe that resinosa must be a weather-hardy variety. In the microscopic 

 structure it is similar to silvestris and it is questionable if in other respects it 

 is similar to this variety. It appears to me that in Europe it is not being cultivated. 

 All that I received under this name were other varieties. It appears to me to be 

 closer to the Japanese densiflora than to silvestris ; the plant in herbariums mostly 

 regarded as Pinus Massoniana is P. Thnnbergii .a variety related to P. Laricia , whereas 

 the real Massoniana from south China is close to the Khasia, perhaps also is identical 

 with it. My drawing-apparatus from Russia is here, but first I have to take care of
