﻿8 SEEDS AND PLANTS IMPORTED. 



oval-elliptic leaves are usually rounded and emarginate or mucronulate, 

 but occasionally acute; often all forms are found on the same shoot.

45708. Mobus acidosa Griffith. Moracese. Mulberry. 

 Usually a broad shrub from 3 to 16 feet in height, but occasionally 



forming a tree up to 25 feet in height. It is found in the Provinces of 

 Hupeh and Szechwan, China. The leaves are very variable in size and 

 shape and are not used for feeding silkworms. The fruits are dark red 

 or shining black and palatable. (Adapted from Sargent, Plant ae Wil- 

 sonianae, vol. 3, p. 300.) 



45709. Peunus sebetjlata pttbescens Wilson. Amygdala cese. 



Flowering cherry. 

 " At its best this variety is a tree of moderate size, from 13 to 16 

 meters tall and from 1 to 2 meters in girth of trunk, but I saw very few 

 such large trees in Japan. In habit and in the size and color of the 

 flowers it agrees closely with var. spontanea (white or pink, from 1.5 

 to 2.5 centimeters, usually 2 centimeters, in diameter). The branch- 

 lets as a rule remain gray for a longer period and do not assume the 

 characteristic chestnut-brown color until after several years." (Wilson, 

 The Cherries of Japan, p. 35.) 



45710. Peunus tomentosa Thunb. Amygdalacese. 



This shrub, 6 to 8 feet in height, appears perfectly hardy and vigorous; 

 it flowers and fruits well at the Arnold Arboretum and withstands per- 

 fectly the rigorous winters at Ames, Iowa ; its fruit buds are hardy and 

 its flowers endure severe frost without injury. It forms a broad, spread- 

 ing, twiggy bush of numerous branches rising from the ground and clothed 

 with branches to the base. These lower branches, where they touch the 

 moist ground, often send out roots and form independent plants. The 

 bark is a gray or bronzy brown, smooth at first, but finally scaling off 

 laterally in thin flakes like the bark of the yellow birch. The downy gray 

 young branches are thickly covered with buds, from which a profusion 

 of flowers and leaves appear simultaneously in early spring. The ses- 

 sile flowers, crowded in the axils of the leaves, are smaller than those of 

 the common cherry and are white or light rose in color. The leaves are 

 ovate, serrate, sparingly hairy above, densely and softly so beneath, with 

 long, slender, persistent stipules. The red cherries, half an inch in diame- 

 ter, are slightly covered with very short, inconspicuous hairs; the firm, 

 juicy, pleasantly acid flesh is without the noticeable staining qualities 

 characteristic of some of the wild cherries and plums. With careful 

 selection and cultivation this little cherry might prove of some economic 

 value. Native to northern China. (Adapted from Garden and Forest,, 

 vol. 5, p. 58.) 



45711. Peuntjs tomentosa endotbicha Koehne. Amygdalacese. 



This variety differs from Prunus tomentosa in that the leaves are- 

 elliptic to oblong, with a very short petiole, and the fruit is dark red, 

 about half an inch in diameter. 



45712. Carica papaya L. Papayaceae. Papaya- 



From the city of Panama, Panama. Presented by Mr. B. H. A. Groth. Re- 

 ceived January 2, 1918. 

 Papaya seeds imported for experimental purposes.
