undersigned received from the Botanical Garden at Hong 

 Kong a few seeds of this small evergreen shrub. The 

 seeds germinated well and the plants grew rapidly, 

 attaining a height of about a foot iu a year. During the 

 summer of the second year the rather bushy plants 

 flowered well aud bore a crop of shining red berries 

 which were very conspicuous throughout the winter. 

 When well grown and bushy the plant is quite orna- 

 mental, its habit being dense and the color of its 

 leaves daik green The flowers aie white, and are 

 li )rne m dense trusses at the extremity of each shoot.
