Chron., 1892, xi., p. 502). Mr. Seden tells me that this record is quite

now in flower. This plant is generally known under the joint names of its 
two parents, but it was described by Reichenbach, in 1886, under the name 
of D. X melanophthalmum (Gard. Chron., 1886, xxv., p. 426), and in the 
previous year, probably by the late Mr. Gower, as D. X Waltoni (Garden,
