The Chromosome Morphology of Trillium erectum L.
The Chromosomes of T. erectum L. from Virginia populations are similar to the published morphology of T. erectum chromosomes in the literature.  See Huskins, C.L., and Smith, S.G.  1935.  Meiotic chromosomes in Trillium erectum L. Ann. Bot. 49:119-150.  Also see Chinnappa, C.C. and J.K. Morton.  1978.  Heterochromatic banding patterns in two species of Trillium.  Canad. J. Genet. Cytol.  20:475-481, and Wilson, G.B., and E.
