Microhabitat Details:
Move to CRPR 1B or 4? Many herbarium specimens of H. intercedens are possible misidentifications of H. depressum; need annotations. Many mainland occurrences are in decline or possibly extirpated; need field surveys. Threatened by development, habitat loss, road construction, and non-native plants. Previously confused with H. pusillum. Similar to H. depressum; the two may hybridize in RIV Co. See Acta Inst. Bot. Acad. Sci. U.R.S.S. Ser. 1, Fasc. 5:222 (1941) for original description and Nordic Journal of Botany 2:307-321 (1982) for taxonomic treatment.
