Pyrus caneseens Spach. A probable hybrid between P. nivalis 

 and P. salici folia, between which species it is almost in- 

 termediate. This tree is very handsome in spring with 

 its very white young leaves, which become shiny, dark 

 green above when mature. The fruit is pale green, 

 much shorter stock than that of P. nivalis, 42796. Pyrus 

 amygdaliformis Villars. A large, rounded shrub or small 

 tree, occasionally 20 feet high. Leaves very variable 

 in shape and size; white flowers one inch across ap- 

 pearing in April; fruit orange-shape, about an Inch 

 across, yellowish-brown, on a short thick stalk. Not 

 especially valuable for the garden except for its 

 picturesqueness when old. Native of the Mediterranean 

 region. 42797. Pyrus nivalis Jacq. A small sturdy tree 

 with woolly, white young shoots and young leaves; the 

 flowers pure white, one and one-half inches across, 

 produced in April in conspicuous clusters. Fruit one 

 and one-half inches or more wide, rounded, yellowish- 

 green. This eastern European tree is very beautiful 

 early in the season because of its pure white leaves 

 and numerous flowers. In France the trees are culti- 

 vated for their fruits which are eaten when bletted. 

 42798. Pyrus sinai Desf. This pear, which is related to 

 P. amygdaliformis, is supposed to have originated in Asia 

 Minor on the Islands of the Greek Archipelago. Its 

 leaves in spring are white with down, becoming smooth 

 and shiny later.
