flowers, deep-red fruits, and thin ovate-lanceolate leaves. The shrub is said 

 to be somewhat hardier than P. uniflora. The plant is of striking habit, and the 

 clusters of large bright-yellow flowers must make it a brilliant sight on its 

 native Mongolian hills from Mukden to the Yaboo. It is early blooming, but 

 at the Arnold Arboretum it bears only a few fruits." (D. C. Peattie.) 



55712. Dioscorea alata L. Dioscoreacese. Greater yam. 



From Bridgetown, Barbados, British West Indies. Tubers presented by 

 John R. Bovell, Director of Agriculture. Received July 7, 1922. 



" Barbados Red. The tuber has a purple inner skin, with white flesh usually 

 tinged or mottled with purple. The vine is four angled, with rather prominent 

 maroon wings. The leaves are opposite, broadly ovate, cordate, acuminate; 

 veins maroon; sinus deep and narrow; petioles maroon at base and apex. 

 In the cooked yam the purple color is pale, and the flesh is mealy and of good 

 flavor. The tubers often weigh several pounds each and are usually some- 

 what cylindrical. This is a standard variety in the West Indies and should 

 be a good market yam for this country." (R. A. Young, > 



55713. Phyllostachys sp. Poacese. Bamboo. 



From Tangsi, Chekiang, China. Plants collected in 1907 by the late Frank 

 N. Meyer, Agricultural Explorer of the United States Department of 

 Agriculture. Received June, 1908. Now numbered for convenience in 

 distribution. 



"A small-growing variety not over 10 feet in height, forming dense clumps. 

 The small wiry stems make excellent plant stakes and small fishing rods. It 

 is quite hardy, withstanding freezing temperatures." (Peter Bisset.) 



Originally introduced under S. P. I. No. 23233 (Meyer's No. 301), but as it 

 does not agree at all with Meyer's note it is necessary to renumber it. 



55714. Hordeum vulgare pallidum Seringe. Poaceae. Barley. 



From Algiers, Algeria. Seeds presented by Dr. L. Trabut. Received July 

 8, 1922. 



" Trabut. A very hardy variety selected from the barleys of North Africa."

55715 to 55717. 



From Jamaica Plain, Mass. Presented by Dr. C. S. Sargent, Arnold Ar- 

 boretum. Received July 5, 1922. 



Seeds of the following varieties of the Japanese flowering cherry (Prunus 

 serrulata Lindl.) are to be grown for trial as stocks for edible-fruited cherries. 



55715. Prunus serrulata ptjbescens Wilson. Amygdalacese. 



A tree up to 55 feet in height, with a trunk sometimes 7 feet in cir- 

 cumference and leaves with pale-green lower surfaces. The white or 

 pink single flowers are usually about four-fifths of an inch in diameter. 

 This variety, known as Kasumi sakura, has the widest distribution of 

 any of the Japanese cherries and flowers about two weeks later than 

 Prunus serrulata spontanea, from which variety it differs chiefly in the 

 slight hairiness of the leaves. (Adapted from Wilson, Cherries of 

 Japan, p. 31.) 



For previous introduction, see S. P. I. No. 45709. 



55716. Prunus serrulata sachalinensis (Schmidt) Makino. Amyg- 

 (P. sargentii Rehder.) [dalacese. Sargent's cherry. 



This variety, the Yama sakura of northern Japan, is very similar to 

 Prunus serrulata pubescens, except that the leaves are not hairy, and 

 the flowers, which are pink or rose colored, rarely white, are usually a 

 little more than an inch in diameter. It is the handsomest of all the 

 wild cherries of eastern Asia and is the parent of several of the finest 

 double-flowered Japanese cherries. (Adapted from Wilson, Cherries of 

 Japan, p. 35.)
