SEEDS AND PLANTS IMPORTED. 



37578 to 37600— Continued. 



37584. Malus baccata (L.) Moench. Siberian crab apple. 

 (Pyrus baccata L.) 



See S. P. I. No. 37008 for description. 



37585. Malus cerasifera Spacli. 



" A cross between Pyrus prunifolia and P. haccata and a very 

 beautiful crab. Flowers white, fruit about the size of a cherry, 

 colored purplish red. The calyx teeth sometimes remain on the 

 fruit, as In P. prunifolia, sometimes fall away." (W. J. Bean, 

 Trees and Shrubs Hardy in the British Isles, vol. 2, p. 291, under 

 Pyrus cerasifera.) 



37586. Malus baccata (L.) Moench. Siberian crab apple. 

 Var. maxima. 



37587. Pyrus canescens Spach. 



" Probably a hybrid between Pyrus nivalis and P. salicifolia. In re- 

 gard to it Decaisne wrote that ' it is intermediate between P. nivalis and 

 P. salicifolia; its leaves are of the same size as those of nivalis, and 

 often twisted as in salicifolia.' They are lanceolate or narrowly oval, 

 finely round toothed, very white when young, shining dark green above 

 when mature. Fruit pale green, much shorter stalked than P. nivalis. A 

 handsome tree in spring." (W. J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 2, p. 289.) 



37588. X SoEBUS hostii (Jacq. f.) Heynh. 



"Pyrus hostii {Sorbus hostii Hedlund) is a hybrid between the above 

 [P. chamaemespilus Ehrhart] and some form or ally of P. intermedia. The 

 foliage is much larger than of P. chamaemespilus, and more resembles 

 that of P. intermedia in size and in the presence of down c"i the lower 

 surface ; the toothing is sharp and jagged. In the dense, compact inflores- 

 cence and in the upright, pinkish petals the influence of P. chamaemes- 

 pilus is apparent. P. hostii is found wild on the Alps of Austria." (TT. 

 J. Bean, Trees and Shrubs Hardy in the British Isles, vol. 2, p. 280.) 



37589. X SoRBUs latifolia (Lam.) P6rs. 



(Pyrus rotundifolia Moench.) 



" A tree 30 to 45 feet, sometimes over 60 feet high ; branchlets downy 

 when young, becoming by winter shining and quite smooth. Leaves 

 roundish ovate, 2 to 4 inches long, often nearly as wide at the base as 

 they are long; the apex pointed, the base either truncate or broadly 

 wedge shaped ; margin either cut into triangular, pointed lobes which are 

 sharply toothed, or simply jaggedly toothed ; smooth, dark lustrous green 

 above, covered beneath with a grayish felt; ribs 6 to 10 on each side; 

 stalk downy, one-half to 1 inch long. Flowers white, five-eighths inch 

 across, borne in corymbs 3 inches wide during May ; stalks and calyx very 

 woolly. Fruits globular, one-half inch in diameter, dull brownish red. 



" This interesting tree was first discovered in the forest of Fontaine- 

 bleau early in the 18th century. Its origin has given rise to considerable 

 difference of opinion, but it is generally believed to be a hybrid between 

 Pyrus aria and Pyrus torminalis. In many respects, notably in shape 

 and woolliness of leaf, and in colour of fruit, it is certainly intermediate 

 between them. Whether the Fontainebleau tree be a hybrid or not (and 

 it is said to come true from seed), very similar ones found in middle
