Tetraploid plants (2n=28) were induced in the five strains (strain nos. 28,35,37,38 and 39) of Phlox drummondii (2n=14) by treating seedlings with colchicine, and their morphological characters were studied in relation to the original diploids. As compared with the diploids, the induced tetraploids were characterized by broader leaves, larger stomata, more chloroplasts per guard cell, later blooming, larger and fewer flowers and larger pollen grains.
