On the uppermost axillae spring the flowers upon short 

 stalks. The flowers consist of a tubular five- toothed, or 

 five-lobed calyx, the teeth of which, at an after period, are 

 reflex, — and of a monopetalous corolla, bell- shaped, of a 

 Berlin blue colour, internally adorned with yellow points. 

 The margin of the corolla has five larger, and as many small-
