This species was first described by Sir J. D. Hooker in 1883; the name used 
being, however, preoccupied it is necessary to provide another. In August 1875, 
a drawing was made from a living plant to which drawing, and to the specimens that 
correspond, the Mss, name now used was attached. The figure given on PLATE 64 is a 
reproduction of the drawing alluded to.
