The general karyomorphological characteristics of fifteen taxa of Lycoris have been studied and the results are itemized as follows.1) The resting nuclei of all examined taxa are diffused type.2) Three fundamental types of chromosome are recognized; i.e. large metacentrics (M type), telocentrics (T type) having heterochromatic block at the proximal region, and acrocentric chromosomes (A type). Other types such as M', T', a and m are produced from three fundamental types by various structural changes. Details will be reported in the forthcoming papers.3) C-banding pattern and pairing behaviour in each of the fundamental types of chromosome suggest that they have partial homology with one another.4) The quantity and position of C-banding positive constitutive heterochromatin in M and T type chromosomes of the genome of L. traubii is remarkably similar to those of Nothscordum fragrans, Allioideae.
