places, on the face of mouDtain cliffs. It bears the Chinese 

 name of Ai-pai-ts'ai, or Cliff Cabbage, and is much esteemed 

 as a medical simple. Mr. Henry in his notes states that 

 the flowers are rose-coloured, when it may be assumed 

 that they vary in colour, as they are decidedly pale cowslip 

 yellow as grown at Kew, with a faint pinkish flush on the 

 back of the corolla tube, and the throat is dotted with red 

 on each side within. 



I may suggest Trianophora (a Greek name for Neptune's 

 Trident), as a sectional name for this plant, in allusion to 

 the trifid calyx teeth, deferring the question of its form- 

 ing a genus distinct from Rehmannia until the genus is 

 more fully represented, as it will doubtless be by additions 

 from unexplored China. 



The plant here figured was raised from seed taken from 

 a specimen collected by Dr. Henry. It flowered in a cool 

 greenhouse of the Royal Gardens in August, 1888, and 

 died after flowering.— J. D. H.
