2 PLANT MATERIAL INTRODUCED 



In propagating the papaw, Ashnina triloba (No. 69166), attention should be 

 called to this outstanding native fruit which has so much to recommend it in 

 its wild state and which has received so little attention at the hands of plant 

 breeders and horticulturists. It should be given special consideration in con- 

 nection with the custard apple, Ankona cherimola, and oilier species. Selection 

 and hybridization of these fruits should be attempted under glass or in south- 

 ern areas having climatic conditions favorable to such plants. 



The Cohune palm, Attalea cohune (No. 69063), although already established 

 in a few places in Florida, is deserving of much greater attention. It is a 

 magnificent palm and one that should be in every good collection. 



The copihue, Lapageria rosea (No. 69168), the national flower of Chile, is a 

 woody vine producing extremely showy flowers. While it has been introduced 

 into the United States a number of times, its exacting requirements have pre- 

 vented its ever being commonly cultivated. It should be given special trial 

 in the immediate coastal area of the Pacific coast wherever climatic conditions 

 approach those of its native habitat in central and southern Chile. 



On account of the difficulty with which Davidia involucrata (No. 69872) is 

 propagated, it has not become common in this or other countries. It is possible, 

 however, to grow it from cuttings, also from seeds. When in bloom the large 

 showy white floral bracts make the tree very conspicuous. It is deserving of 

 special consideration. 



The botanical determinations of these introductions have been made and the 

 nomenclature determined by H. C. Skeels, and the descriptive matter has been 

 prepared under the direction of Paul Russell, who has had general supervision 

 of this inventory.
