“Polyploidy in Bluebells”

Abstract

J. YANNEY WILSON has recently given an account of polyploidy in bluebells (Endymion non-scriptus and E. hispanicus)1. There are some errors in this paper which it is desirable to correct. The “extraordinarily large forms” to which reference is made have not been determined by me as hybrids. Apparently the author has misunderstood the excellent coloured figures in the Botanical Magazine, N.S., 176 (1952). The central figure is of Endymion hispanicus, the left-hand one is of E. non-scriptus, and the right-hand one is of the putative hybrid. Further, the impression is given that Mr. Yanney Wilson examined my material cytologically ; but he has not done so and I have not had the opportunity of studying his plants taxonomically.
