| 説明 | Cirsium arvense is an exotic rhizomatous thistle with small flowering heads, involucre less than 2 cm long, and with leaves that are green on both surfaces (not white woolly on one or both surfaces, like the native species of thistles). This site lies along a draw in the neighborhood on the north side of Table Rock, Boise, Ada County, Idaho. |
