Phlox divaricata L. Bluk Phlox. There are two geographic varieties of this species; the eastern one, var. canadensis, has its dispersal center in Kentucky, and from there ranges to Georgia, to the western boundary of Indiana, to central ^lichigan and to northwestern Vermont. Variety lap- hami, the western representative, has spread out from the Ozarks to western Florida, eastern Texas, southern Minnesota, and the east edge of Illi- nois. Both occur in deciduous wood- land, in circumneutral soil, often on river flood-plains, but sometimes on steep slopes and even limestone cliflfs. They are accordingly readily culti- vated in rich garden loam. As the common name implies, the corolla-color of this species often tends toward blue, although strictly speaking it should be termed light violet or lavender; and it occasionally ranges to lilac or light purple. Pallid and pure white forms are also fre- quently met with. The eye may be white or suffused with rose, although definite striae are rarely developed. Corolla-lobe outline varies markedly, but the two geographic varieties are distinguished chiefly on one feature of it; the eastern one usually has dis- tinct notches in the ends of the lobes, while in the western one these are almost entire or mucronate instead. As to foliage characters, it may be noted that the crowns produce in sum- mer prostrate sterile shoots which tend VT
