Place Names supplemental information
Eleocharis Meadow (a former quarry and currently a de facto wetland)
Sector 31 B4 near the intersection of Road E and Trail
13 SE of Searsville Lake
This vernally wet area is currently
the only known location of common spike-rush (Eleocharis macrostachya) and
toad rush (Juncus bufonius var. bufonius)1. Bordering the
meadow is wild licorice
(Glycyrrhiza lepidota) and red-flowered currant (Ribes sanguineum var. glutinosum)2. Growing on the south-facing
slope of the quarry embankment is the only known population of the parasite clustered broomrape (Orobanche fasciculate) whose
host is wild buckwheat
(Eriogonum nudum var. auriculatum). A few meters south at the Trail
12 footbridge is the only location of water
plantain (Alisma triviale)3.
