206 THE ORCHID STUD.BOOK. [Part I. 
There is a slight doubt about the parentage of this hybrid. It was first 
exhibited as a hybrid from C. javanicum, which was afterwards corrected to C. 
javanicum virens, with the statement that the latter was the seed parent. Han- 
sen cites Bergm. O. des Semis as the authority for the name C. x Sementa, but it 
is not in the copy accessible to us (¥. S. H. Fr. 1892), except as C. x javanico- 
superbiens (p. 280).
