. Contributions from the Botanical Laboratory, vol. 9. Botany; Botany. 4'-'-'-^-^W two counties, Alleghany^ and Fig. 2. Distribution of Phlox hucMeyu Bath.^ West Virginia: Found thus far only in Greenbrier' Co. Ecology.—The chief reason for the geographic restriction of this species is seemingly its requirement for a special type of habitat, for in all seven known localities it growls in a gravelly soil derived from a particularly slabby Devonian shale. It is, however, not a pioneer on shale-slopes, being unable to come in until after a thin woodland cover has de- veloped and the soil has become rich in subacid humus. The denser shade of climax forests is also unfavorable to it, and it dies out as they mature. Its thick narrow persistent leaves lead to its classification as moderately xerophytic. The bloom- ing period extends from mid-May to mid-June, the bright phlox-purple flowers attracting insects as do those of the preceding species. Variation.—Only minor variations, of nutritional origin, have been observed. Cultivation.—The difficulty of matching the native habitat conditions of this plant is likely to prevent its ever being much cultivated. 1 Journ. Wash. Acad. Sci. 20: 25. Fig. 1. Phloa' hiicl-leyi.
