The Chromosome Morphology of Trillium sulcatum Patrick.

 

The chromosomes of Trillium sulcatum show some differentiation from T. erectum, with  which it is closely related (Patrick 1984).  This is particularly true for the B, C and D chromosomes.  See Patrick, Thomas S.  1984.  Trillium sulcatum (Liliaceae), a new species of the Southern Appalachians.  Brittonia 36(1):  26-36.
