40561 to 40600— Continued. 



40576. Cotoneaster dielsiana elegans Rehder and Wilson. 



This variety differs from the typical forms described under S. P. I. 

 No. 40575 in its thinner, yet more persistent leaves, smaller pendulous 

 brick or orange red fruit, (Adapted from Sargent, Plantae Wil- 

 sonianae, vol. 1, p. 166.) 



40577. Cotoneaster divaricata Rehder and Wilson. 



For previous introductions and description see S. P. I. Nos. 37596, 

 38149, and 40164. 



40578. Cotoneaster salicifolia floccosa Rehder and Wilson. 

 "An evergreen shrub 6 to 12 feet high, the branchlets very slender, 



downy at first, but becoming smooth and of a dark reddish brown by 

 the end of the season. Leaves leathery, lanceolate or narrowly ovate, 

 wedge shaped at the base, tapering to a sharp point ; three-fourths to 

 24 inches long, one-fourth to three-fourths inch wide ; the upper sur- 

 face glossy green, wrinkled, not downy ; the lower one covered at first 

 with silky white floss, some of which falls away by the end of the 

 year, showing the grey-white surface beneath; veins in 7 to 14 pairs; 

 leafstalk about one-eighth inch long. Corymbs about 1 inch wide, 

 carrying 9 to 15 flowers ; stalks and calyx woolly, the teeth of the 

 latter triangular. Fruit roundish, about one-fourth inch in diameter, 

 bright red, containing usually three stones. Introduced by Wilson 

 (No. 1133a) from western China in 1908, and again in 1910. A very 

 graceful, distinct, and attractive evergreen, highly recommended by its 

 collector for the beauty of its fruit." (W. J. Bean, Trees and Shrubs 

 Ha nil) in the British Isles, vol. 1, p. ffl'f.) 



40579. Cotoneaster saiicifolia rugosa (Pritz.) Rehder and Wilson. 



" In this variety the leaves are larger, up to 3 inches long and 1J 

 inches wide, the veins numbering 6 to 12 pairs. The fruit is coral 

 red, larger than in var. floccosa, and contains usually two stones. The 

 plant is more vigorous, coarser looking, and with bigger leaves than 

 var. floccosa, but in many respects similar. Introduced by Wilson 

 (No. 335) in 1907 from western Hupeh, where he found it 9 feel high." 

 (W. J. Bean, Trees and Shrubs Hardy in the British Isles, vol. 1, 

 p.JtU.) 



40580. Deutzia schneideriana laxiflora Rehder. Hydrangeacea;. 

 Shrub 2 to 2J m. high from western Hupeh, China. Leaves oblong- 

 lanceolate, acuminate, base rounded or broadly wedge shaped, remotely 

 and irregularly denticulate, 2 to 3 inches long and three-fifths if 1 inch 

 broad, with sparse hairs above and densely hairy below. Inflorescence 

 broadly paniculate. Differs from the type chiefly in flu 1 leaves being on 

 their under side only sparingly stellate-pubescent and therefore green, 

 and in the looser and broader panicles. (Adapted from Sargi ut. Plantae 

 Wilsonianae, vol. 1, p. 7-8.) 



40581. Euonymus radicans acutus Rehder. Celastracese. 



"This western Chinese variety resembles, in its climbing habit, /'. 

 japonica radicans Miquel [now called /•:. radicans], bul is easily dis- 

 tinguished from this, as well as from the type, by the thinner, acute, or 

 shortly acuminate leaves distinctly veined beneath. In typical /. 

 japonica [E. radicans], the leaves are obtuse or obtusish, more coarsely
