51873. Malus floribunda Sieb. Malacese. Crab apple. 

 {Pyrus floribunda Kirchn.) 



Seeds of one of the handsomest of all crab apples and one of the 

 earliest to flower. It is a broad shrub with a trunk dividing at the 

 base into several large branches. The pink flowers, which are deep 

 rose color in the bud, turn white before the petals fall and are pro- 

 duced in the greatest profusion. The dark-green foliage is abundant, 

 but the yellow or orange-colored fruits are not much larger than peas 

 and make little show. The origin of this plant is uncertain. It was 

 first sent to Europe from Japan, but it is not a native of that country. 

 It was probably introduced from China, although it does not appear 

 to be known in China now in a wild state. (Adapted from American 

 Florist, vol. 46, p. 9^5.)

51874. %lALtJS NiEDzwETZKYANA Dicck. Malaccse. Apple. 

 {Pyrus medzwetzkyana Hemsl.) 



Seeds of a small free-growing tree with long, straight, rather thick 

 flowering branches and smooth, very dark purple bark. The lanceolate 

 leaves, 3 to 5 inches long on slender petioles 1 to 2 inches long, are rather 

 thick, stiff, and tinged red on the fruiting branches. The petiole and midrib 

 are bright red and slightly hairy. The deep rose-purple flowers, 1 to li 

 inches long and three-fourths of an inch across, are very numerous and 

 clustered at the ends of short, lateral branchlets. The woolly calyx is 

 white. The pendulous conical fruits, If to 2 inches long, have crimson- 

 purple skin and rose-purple, pleasantly flavored flesh. The wood is red 

 also, and the leaves turn red in autumn. (Adapted from Curtis'' s Botan- 

 ical Magazine, pi. 7975.)

51875. Mallts pRUNiroLiA (Willd.) Borkh. INIalaceie. Apple. 

 (Pyrus prunifolia Willd.) 



Seeds of a small ornamental tree native to North China and southern 

 Siberia, with l^eautiful white flowers 1^ inches across, in 6 to 10 flowered 

 umbels, and smooth globose berries, 1 inch in diameter, green, amber 

 yellow, and bright red in varying proportions. The young shoots, peti- 

 oles, under surfaces of the leaves, and inflorescences are cottony.

51876. PoPULUs ADENOPODA Maxim. Salicace?e. Poplar. 

 Cuttings of a very distinct species easily recognized by the long-acumi- 

 nate, closely crenate leaves, greenish beneath, of old mature trees. The 

 common low-level poplar of Hupeh and Szechwan and the more eastern 

 parts of the Yangtze Valley. In western Hupeh it is very abundant in 

 open country and woods from river level up to an altitude of 1,500 

 meters. It is a rather slender, shapely tree, 20 to 25 meters or more 

 tall, with a straight trunk clear of branches for 10 to 15 meters and 

 clothed with smooth pale-gray bark, which on old trees and near the 

 ground becomes dark and slightly fissured. The branches are thin, as- 

 cending spreading, and form an oval crown. The leaves vary consider- 

 ably in degree of pubescence, but on old trees they are glabrous at ma- 

 turity. On young trees and on adventitious shoots they are densely 

 pubescent. (Adapted from Sargent, Plantae Wilsonianae, vol. 3, p. 23.)

51877. PoPULUs MAxiMowiczii A. Henry. Salicacese. Poplar. 

 Cuttings of a handsome, stately tree, the most satisfactory of the pop- 

 lars, of upright, ovate outline, which comes out in foliage 10 days be- 

 fore other trees and is always green, the foliage haii.L'ing on as late 

 in the season as almost any deciduous tree. It thrives on thin gravelly 

 soil, so dry that Norway spruce and white ash could not survive on it. 

 In favor of the tree is its rapid growth, 3 to 5 feet a year for the first 

 eight- years. Under similar conditions the Norway maple may grow 

 6 to 24 inches and the red oak and pin oak 12 to 30 inches. The leaf
