This is i i i iderably in the color of 
flowers, length of the tasers wm des af the lonven, Wo cannot find a single 
character by which to separate R. Harrovianum Hemsley from it. Monbeig's No. 6 
has unusually large flowers with included stamens and possibly represents a distinct 
variety. Our material, however, is insufficient to decide this.
