INVENTORY OF SEEDS AND PLANTS IMPORTED 

 BY THE OFFICE OF FOREIGN SEED AND PLANT 

 INTRODUCTION DURING THE PERIOD FROM OC- 

 TOBER 1 TO DECEMBER 31, 1912 (NO. 33; NOS. 

 34340-34727). 



INTRODUCTORY STATEMENT. 



The remarkable success which has attended the introduction of 

 Chinese plants into America is no doubt due to the similarity between 

 the climate of eastern China and that of eastern North America. This 

 success of the Chinese plants, which nurserymen are rapidly coming 

 to realize, will give special interest to the remarkable collection of 

 plants from western China which, through the courtesy of the Arnold 

 Arboretum, will be distributed from this office as soon as a stock of 

 them has been prepared. The collection was made by Mr. E. H. 

 Wilson, now of the Arboretum, during his expeditions in the various 

 provinces of western China, and among the 79 different numbers 

 (34523 to 34601), most of which will find a place somewhere in Ameri- 

 can horticulture, the following are of special economic importance as 

 plant-breeding material or for use as ornamentals in both city and 

 coimtry yards: No. 34601, a new and remarkable species of wild 

 peach, Prunus mira, which bears an edible fruit containing a smooth 

 instead of a furrowed stone (a character quite imknown heretofore 

 among peaches), which may be used in the improvement of the 

 commercial peach; Nos. 34525, 34527, and 34546, three promising new 

 hollies which may prove hardy here; No. 34537, a new Ampelopsis, 

 A. megalophyUa, with large, divided leaves 3 feet in diameter; No. 

 34544, a 70-foot maple, Acer catalpifolium, the leaves of which color a 

 golden yellow in autumn; Nos. 34538 and 34549, the Yunnan pine, 

 Pinus sinensis yunnanemis; No. 34555, the Chinese butternut, Juglans 

 cathayensis, a bush or small tree; Nos. 34558, 34560, 34563, 34574, 

 34576, and 34582, six species of Prunus for those who are doing breed- 

 ing work in this genus; Nos. 34580 and 34581, two species of Vitis; 

 No. 34583, the Chinese close relative of the southern sweet-gum tree, 

 lAquidamhar formosana, which has proved hardy in the Arnold 

 Arboretum; No. 34589, an undescribed species of quince, Cydonia 

 sp.; No. 34590, a new spine-bearing hazelnut (Corylus sp.) with large 

 fruits; and No. 34599, a new species of Magnolia, M. wilsonii.
