Chalcas exotica{L. )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.

^ :t ~^.898. It is the handsomest yellow-flowered clematis in 
cultivation, the finest flowers being about four inches 
across. It differs from C. orientalis 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
