Species: Cirsium brevistylum
Encyclopedia of Puget Sound
Short-styled Thistle is an herbaceous perennial with thick, succulent, sparingly branched stems that are 4-25 dm high, and which arise from a taproot. The clasping, alternate leaves are pinnately lobed or toothed with spines along the margins. The foliage is thinly to densely covered with tangled white hairs. A few short-stalked flower heads are clustered at the tips of the stems. Each head is 2-4 cm high and has 2-3 series of linear, nearly non-overlapping involucral bracts, which are sparsely to densely covered with long, tangled hairs, the outermost of which have short, erect spines. There are numerous tubular, purplish red disk corollas that are 16-24 mm long. Ray flowers are lacking. The seed has a pappus.
