 937. — Banisteria, L., Sw. B. cserulea, iam. Ifeteropteris cserulea, .ffiA., Juss.!: there is 

 no character to distinguish this : the blue colour of its petals rests merely upon the authority 

 of Plumier, and is probably an old mistalce, as the petals , are undoubtedly yellow {^Sl., Maef^, 

 or a change of colour may perhaps take place with age, as according to the figure of the Bot.

 LinuEeus's name is not to be adopted : for he confounded different plants among his syno-

 longs to the preceding species.
