49669. Davidia involucrata vilmobiniana (Dode) Heinsl. Cornacei?. 



(Seeds.) A tree 40 to 50 feet tall, native to western China, with 

 alternate, ovate, coarsely serrate, bright-green leaves 2 to 4 inches long, 

 inconspicuous flowers in terminal globular heads, and greenish yellow 

 fruits with brown dots, nearly 2 inches long. The bracts are like those 

 in the ts'pical form. (Adapted from Curtis\s Botanical Magazine, pi. 

 8432.)

49670. Dexjtzia vilmorixae Lemoine and Bois. Hydrangeaceae. 



(Plants of M. Vilmorin No. 1547.) A vigorous erect shrub, native to 

 China, suggesting in general appearance some of the smaller kinds of 

 Philadelphus. Late in the spring it bears clusters of pure-white flowers 

 with yellow anthers. Because of its late flowering it usually escapes 

 the injurious eflfects of late frosts. (Adapted from Gardening Illus- 

 trated, July 7, 1917.)

49671. Dexjtzia sp. Hydrangeaceae. 

 (Plants of M. Vilmorin No. 4277.) 



49672. Hemiptelea davidii (Hance) Planch. Ulmacese. 

 {Zelkova davidii Hemsl.) 



(Cuttings.) A stout-branched shrub, native to Mongolia, with smooth 

 brown bark and long stout spines on the smaller branches. The caducous 

 leaves are small, oval, and deeply dentate, and the very inconspicuous 

 flowers appear in April. (Adapted from Revue Horticole, vol. 85, p. SO.) 



49673. Hypericum patulum henryi A^eitch. Hypericacea?. 



(Plants of Wilson No. 1355.) This variety of Hypericum patulum, 

 first discovered by Dr. A. Henry in Yunnan, China, is hardier than the 

 typical form and sturdier in habit. The ovate dark-green leaves are 

 2 to 3 inches long, and the flowers are of a rich glowing yellow and about 

 2 inches wide. (Adapted from Gardeners' Chronicle, third series, vol. 

 38, p. 179.) 



For previous introduction, see S. P. I. No. 43849. 



49674. Jasminum nudiflobum Lindl. Oleaceje. Jasmine. 

 "A yellow-flowered jasmine, growing on dry banks, ravines, etc., in 



Shansi, China, where it flowers before the leaves come out, sometimes 

 even in midwinter. The plants are of spreading habit, with very long, 

 slender, green branches which root wherever they touch moist ground, 

 making them very desirable for covering old walls, banks, etc." {Frank 

 N. Meyer.) 



For previous introduction, see S. P. I. No. 38248. 

 49675 to 49677. Ligusteum delavayanum Hariot. Oleacese. Privet. 



This hardy shrub was first discovered by Abbe Delavay in the moun- 

 tains of Yunnan. China, where it became 2 to 4 meters high. In habit 

 it is prostrate-spreading except for a few perfectly upright branches 

 which rise from the center of the shrub. The shining dark-green 

 foliage, which is remarkably persistent, reminds one of a myrtle and 

 with the white flowers and blue-black fruits makes this plant a very 

 attractive ornamental. (Adapted from Sargent, Plantae Wilsojiianae, 

 vol. 2, p. 601, and Revue Horticole, vol. 73, p. 495.)
