H. D. Thoreau, Journal, June 4, 1859
Cornus alternifolia well out. See
June 10, 1856 ("
Cornus alternifolia a day or two, up railroad; maybe longer elsewhere.")
Poa compressa . The Canada bluegrass or flattened meadow-grass, is a perennial flattened meadow grass, similar to common meadow-grass, native to Europe found nearly worldwide as an introduced species. ~
Wikipedia . Specimen in Thoreau herbarium collected on
June 14, 1859 at the railroad causeway. Two other specimens collected at Britton’s Shanty and Great Road on June 2 and 4, 1859, which are in neighboring Lincoln, Massachusetts . The only Journal reference with a specific Concord locale is on June 23, 1860, the railroad at Walden Pond, likely the same locale as his June 14, 1859 collection. ~
Vascular Flora of Concord, Massachusetts. See
June 23, 1860 ("
Poa compressa may fairly begin on the railroad at Walden").
