REPORT OF THE STATE BOTANIST I913 6l 



was planted Douglas fir (Pseudotsuga taxifolia). The 

 largest of the redwoods are now 30 inches in diameter and bear an 

 abundance of cones nearly every year. According to information 

 from an employee of Conrad Apple's seed firm in Darmstadt, the 

 seeds from these redwoods possess less than 4 per cent of germina- 

 tion. As producers of timber, most of the American conifers in 

 cultivation on this estate must be regarded as failures, not because 

 of slow growth, for most of them have made phenomenal growth in 

 the past 60 years, but because they were planted too far apart and 

 are covered with branches nearly to the ground in addition to 

 possessing more than the usual taper at the base. 



On this estate are to be seen some fine plantations which, aside 

 from the faults noted above, give an excellent idea of the wide 

 range of species which can be grown in the climate of the Rhine 

 valley. They include : 



Pinus monticola Dongl. 



" lambertiana DougL 



" ponderosa Laws. 



" jeffreyi " Ore. Com." 



" austriaca Hoss. 

 Picea sitchensis (Bong.) Trautv. & Mayer 

 Abies concolor (Gord.) Parry 



" cephalonica Lond. 



" pinsapo Boiss. 

 Tsuga heterophylla (Raf.) Sarg. 

 Pseudotsuga taxifolia (Lam.) Britt. 

 Sequoia washingtoniana (Winsl.) Sudw. 

 Libocedrus decurrens Torr. 

 Thuya plicata Don 

 Chamaecyparis lawsoniana (Murr.) Pari. 



nootkatensis (Lamb.) Spach. 

 Tumion calif ornicum (Torr.) Greene 



Many other trees are represented by groups or scattered indi- 

 viduals. While most of the species are American, there is a good 

 representation of oriental and Japanese conifers. The coast red- 

 wood (Sequoia sempervirens (Lamb.) Endl.) would 

 hardly be expected to succeed in Germany, in spite of which fact 

 there is a clump of half a dozen trees in a sheltered situation at 

 Weinheim which might be said to be existing, as they show little 

 vigor and some have died. The largest one has produced a few 

 cones.
