THE BOTANY OF THE APPLE TREE. 11 



descriptions of 1900 varieties, and the American Poraological Society's 

 list includes 369. 



(b.) Fruit covered by a short fleshy calyx tube, bearing the calyx lobes. 



6. CHINESE APPLE (Pirus spectabilis Aiton). Leaves elongated- 



elliptical, smooth; flower-stalk and calyx-tube hairy; fruit 

 about as long as its stalk (1 inch), yellowish. A tree 20 to 

 25 feet high, native of China and Japan, often found in cul- 

 tivation, with much " doubled" flowers. 



7. BJNGO APPLE (Pirus ringo Seibold.). Leaves ovate-elon- 



gated, sharp serrate, at first hairy below, but eventually 

 smooth; flower-stalk and calyx white-woolly; fruit wax- 

 yellow with a reddish tinge, 1 to 1J inches in diameter, 

 stalk about as long. A small tree 9 to 10 feet high, native 

 of Japan. Occasionally cultivated for ornamental purposes. 



8. LARGE SIBERIAN APPLE (Pirus prunifolia Willd.). Leaves 



ovate, elongated or elliptical, smooth below, on long petioles ; 

 flower-stalk and calyx hairy or smooth; fruit wax-yellow, 

 to red and even black, 1 to 1J inches or more in diameter, 

 stalk about as long or longer. A tree 25 to 30 feet high, 

 native of northern China, Tartary, and southern Siberia. 

 This is the parent form of the larger cultivated crab apple, 

 such as the Transcendent, Hyslop, etc. 



SECTION 2. Calys lobes falling off after blossoming; styles 3 to 5; 

 fruits 3 to 5 celled. 



A. Leaves rolled in the bud. 



9. SMALL SIBERIAN APPLE (Pirus baccata L.). Leaves elon- 



gated-ovate, smooth, as are the twigs also; flower-stalk 

 and calyx smooth ; fruit small, J to } inch, yellow or red, 

 on a much longer slender stalk (1 to 1 J inches). A tree 25 

 to 30 feet high, native of the Himalayas, Amur, China, and 

 Siberia. This is the parent form of the smaller cultivated 

 crab apples, as the Red Siberian Crab, etc.* 



* Since the preparation of this paper I have seen Dr. Alexandra Batalin's paper, 

 "Notse de Plantis Asiaticis," in Ada Horti Petropolilani, Vol. XIII (1893), pp. 91 

 to 106, in which he describes another apple from the province of Kansa in western 

 China, which is apparently allied to Pirus baccata, and which he names P. transi- 

 toria. It is a tree abont 20 feet in height, with long-petio led, trisected, or tripartite 

 densely pubescent leaves, and a small globose fruit, about inch in diameter. It 

 should be investigated by our horticulturists, as a possible stock for top grafting.
