42.54820604  -89.13937184 +-1138m.
Verbatim Coordinates: T01N R11E sec13
Georeference Remarks: Latitude/Longitude was derived from the Township, Range, Section location. This causes an imprecision.
Habitat: In leaf mold. Rich woods (Quercus borealis dominant, with Ulmus, many Juglans nigra (now all removed), Celtis occidentalis & Prunus serotina) on deep Miami Fine Sandy Loam. Associated species: Adiantum pedatum, Athyrium angustum, Dryopteris spinulosa var. intermedia, Pteridium aquilinum var. latiusculum, Carex convoluta, Arisaema triphyllum, Lilium philadelphicum, Smilax ecirrata, S. illinoensis, Uvularia grandiflora, Smilacina racemosa, Podophyllum peltatum, Ribes missouriense, Rubus occidentalis, Amphicarpa bracteata, Geranium maculatum, Impatiens pallida, Rhus radicans var. radicans, Sanicula gregaria, Galium aparine, Eupatorium purpureum. Carices unexpectedly very rare in this stand. Immature plants of Carex cephaloidea are difficult to distinguish from C. sparganioides. In the former the narrowly ovate or elliptic perigynia gradually taper into a long narrow beak. The membranaceous bodies of the perigynia (subcoriaceous in C. sparganioides) have raised, narrow, thin-winged margins, when present, only above the middle (not so evident as in C. sparganioides). The head is almost always more compact in C. cephaloidea. Pistillate scale length (short in both species) and apex (acute to obtuse in both) are overemphasized by Mackenzie in his key (p. 44) to the group of sect. Bracteosae including C. cephaloid. and C. sparg.
