Average Sugar Maple tree diam- eter at breast height (dbh) was about 33 cm and the maximum was 45 cm for White Ash and Basswood. The general area (approximately 30 x 100 m) at the base of the slope had an unusually high diversity of herbaceous species along with woody saplings of Ironwood (Ostrya virginiana (Miller) K. Koch) and maples. Dominant herbs included Mitella diphylla (Two-leaved Bishop's Cap), and the sedges Carex platyphylla J. Carey (Broad-leaved Sedge) and Carex pedunculata Muhlenb. ex Willd. (Long-stalked Sedge). Other frequent species observed during the autumn visit to the site included Actaea pachypoda Elliot (White Baneberry), A. rubra (Aiton) Willd. (Red Bane- berry), Adiantum pedatwn L. (Northern Maidenhair Fern), Allium tricoccum Aiton (Wild Leek), Amphi- carpa bracteata (L.) Fern. (Hog Peanut), Anemone acutiloba (DC.) G. Lawson (Sharp-lobed Hepatica), Athyrium filix-femina (L.) Roth ex Mert. var. angus- tum (Willd.) G. Lawson (Northern Lady Fern), Carex plantaginea Lam. (Plantain-leaved Sedge), Caulo- phyllum thalictroides (L.) Michx. (Blue Cohosh), Dep- aria acrostichoides (Swartz) M. Kato (Silvery Glade Fern), Diplazium pycnocarpon (Spreng.) M. Brown (Narrow-leaved Spleenwort), Dryopteris goldiana (Hook, ex Goidie) A. Gray (Goldie's Fern), Dryopteris intermedia (Muhlenb. ex Willd.) A. Gray (Evergreen Wood Fern), Eupatorium rugosum Houtt. (White Snakeroot), Gymnocarpium dryopteris (L.) Newman (Oak Fern), Maianthemum racemosum (L.) Link (False Solomon's Seal), Phryma leptostachya L. (Fog- fruit), and Uvularia grandiflora Sm. (Large-flowered Bellwort). Identification Characteristics Although rare, the D. goldiana x D. intermedia hybrid is not difficult to identify because it comb
