This file is an attachment (Attachment 4d) showing informational content about the Class C noxious weed Tall Flatsedge (Cyperus eragrostis) from the Washington State Noxious Weed Control Board website. The document appears to be included as supplementary information for the Montlake Laboratory Landscaping Services contract.

The document provides detailed botanical information about Tall Flatsedge, including its physical description, habitat preferences, and identification characteristics. The plant is described as a tufted, sedge-like perennial with rhizomes that grows 1.3-3 feet tall, typically found in damp grasslands, roadsides, ditches, streambanks, and wetlands. The document includes photos of the plant's inflorescence and notes that it reproduces both by seed and vegetatively through rhizomes. This information appears relevant to the landscaping services contract as guidance for weed identification and control at the NOAA facility.
