flowered, terminal; flowers one-half inch across, with downy stalks; 

 calyx downy, the lobes pointed, triangular; petals purple. Native 

 of western China, and found on Mount Omi by Wilson, who intro- 

 duced it for Messrs. Veitch, with whom it flowered in August, 1908. 

 It grows up to 6,000 feet elevation and will probably be perfectly 

 hardy. It makes growths 10 to 12 feet long in a season. The 

 stipules are rather remarkable." (W. J. Bean, Trees and Shrubs 

 Hardy in the British Isles, vol. 2, p. ^65.) 



40196. Stranvaesia davidiana undulata (Decne.) Rehder and Wilson. 

 Malacese. 



"A low, spreading evergreen shrub, or a tree over 20 feet high, with 

 very downy young branchlets. Leaves leathery, oval-lanceolate, pointed, 

 glossy green, 1| to 3£ inches long, one-half to li inches wide; entire, 

 downy only on the midrib and margins; stalk one-third to one-half inch 

 long, downy. Flowers white, produced in June in terminal, hairy-stalked 

 corymbs, 1£ to 2| inches wide ; each flower about one-half inch across ; petals 

 soon falling; calyx with five triangular lobes, silky hairy when young; 

 stamens about 20. Fruit brilliant red, of the shape and size of common 

 haws. Native of China ; introduced by Wilson for Messrs. Veitch about 

 1901. Unlike the previous species, this appears to be quite hardy. It 

 flowers with great freedom, but the blossoms last in beauty a very short 

 time. Its great charm as a garden shrub is in its abundant crop of 

 bright-red fruits. The leaves, as in Photinia, turn red sometimes before 

 falling. The specific name refers to the frequently wavy margins of the 

 leaves." (IF. J. Bean, Trees and Shrubs Hardy in the British Isles, 

 vol. 2, p. 556, as $. undulata.) 



40197. Tilia euchlora Koch. Tiliaceae. 



"A tree as yet about 40 feet high in this country, but probably con- 

 siderably higher naturally, of graceful, often rather pendulous growth; 

 young shoots smooth. Leaves roundish ovate, oblique and heart shaped 

 at the base, with short, tapered points ; 2 to 4 inches long, often more 

 in young trees, and as much or more wide ; rich glossy green and smooth 

 above, pale green beneath and smooth, except for tufts of hairs in the 

 axils of the veins; marginal teeth small, regular, and slender; stalk 

 smooth, 1 to 2 inches long. Flowers produced in the latter half of July, 

 three to seven together in cymes 2 to 4 inches long, yellowish white. 

 Floral bract linear-oblong, or narrowly lance shaped, 2 to 3 inches long, 

 one-fourth to five-eighths inch wide, smooth, shortly stalked. Fruit dis- 

 tinctly ovoid, tapered to a point, shaggy, with pale-brown wool, one- 

 fourth to one-third inch long. 



." Of doubtful origin ; introduced about 1860. In some respects this is 

 the most beautiful of the limes, on account of its bright-green large leaves 

 and pleasing form. It is remarkably free from insect pests. In the 

 summer of 1909, when not only limes but nearly every other tree and 

 shrub was infested with aphides and other pests, I examined specimens 

 of this lime at intervals during the summer and never found a single 

 parasite on the leaves. Yet it is quite uncommon in this country. On 

 the Continent, however, its qualities are better appreciated, and it is 

 being much planted in streets. Its brilliantly glossy, rounded, nearly 

 glabrous leaves and pendulous branches very well distinguish it. It has 

 been suggested that it is a hybrid between T. cordata and the scarcely
