some obscurity about the colour of the flower of this species, possibly indicating diffe- 

 rent species, or a change during life. In Thwaites' figure of the Ceylon plant they 

 are in one pale yellowish-red, in another of the same cyme a^deep blue purple. In a 

 drawing of Royle's they are nearly pure white, in another they are all pale rosy ; in 

 Wight's Illustrations (of W. mollissima) they are a dingy pale reddish. Brandis, who 

 remarks on this subject and on the various accounts of the scent of the flowers, 

 suggests that they may change colour after expansion.
