 this Bureau and pronounced entirely free from the disease. 

 It is now at eight years from seed bearing a few fruits.

Cluilcas exotica^. )Millspaugh. (Rutaceae. ) 40392. Seeds 

 of the orange jessamine from the Hongkong Botanical Garden. 

 Presented by Mr. W. J. Tutcher, Superintendent, Botanical 

 and Forestry Department. "The orange jessamine is commonly 

 grown in greenhouses on account of its abundant and very 

 fragrant flowers. These are often to be seen along with 

 the mature red fruits, which makes a striking contrast with 

 the panicles of white flowers and delicate foliage. The 

 root-growth of this species is remarkably vigorous under 

 greenhouse conditions. Lemons can be budded on it, and 

 make a rapid growth. It is being tested as a stock for 

 the common citrus fruits in situations in which a vigorous 

 root system is desired." (Swingle, in Bailey, Standard 

 Cyclopedia of Horticulture). In south Florida it makes a 

 beautiful evergreen bush especially well adapted for use 

 in formal gardens. 



Clematis tangutica (Maxim . )Korsh. (Ranunculaceae . ) 40570. 

 Plants of a clematis from the Hon. Vicary Gibbs, Elstree, 

 Herts, England. "A species closely allied to, or perhaps 

 a variety of C. onentalis , growing eight to ten feet high; 

 stems slightly downy. Leaves grey-green, like those of 

 C. orientalis , but downy when young; leaflets raggedly tooth- 

 ed, and sometimes two or three lobed. Flowers rich yel- 

 low, solitary, on downy stalks three to six inches long; 

 sepals nearly two inches long, narrowly ovate, long and 

 slenderly pointed, downy outside and at the edges. Seed- 

 vessels crowned with long-feathered styles. Native of 

 central Asia, introduced to Kew from St. Petersburg in 

 1898. It is the handsomest yellow-flowered clematis in 

 cultivation, the finest flowers being about four inches 

 across. It differs from C. onentalis in the larger flowers , 

 and in the downy stems, flower-stalks, etc. It is a su- 

 perior plant." (W. J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 1, p. 367.) Specimens have flowered at 

 Compton, in the arboretum of Mr. John T. Morris, Chestnut 

 Hill, Pennsylvania.
