Of great interest as an addition to the growing list of genera common, 

 arid restricted, to the Himalayo-Chinese region and the Atlantic States 

 of North America, and specially interesting in this case as the genus 

 has been hitherto monotypic, and known only from the South-Eastern 

 btates. Dr. Henry describes this plant as a ' creeper hanging down 

 trom wall of cliff' (in the Ichang Gorge) with beautiful clnsters of 

 tragrant white flowers.— D. Oliver.
