A black and white botanical line drawing in horticultural style focusing solely on a single flower head of the arrowleaf balsamroot (Balsamorhiza sagittata). Depict a large, sunflower-like composite flower head with a circular arrangement of slender ray florets (petal-like structures) around a dense central disk. The flower head should be about 6 to 10 centimeters (2.5 to 4 inches) wide. Include between 8 and 25 ray florets, most commonly 13 to 21, each ray floret shown as a narrow, elongated ligule with a slightly fringed or tapered tip, radiating evenly around the center. The central disk is densely packed with small tubular disc florets. Emphasize fine, precise linework and strong tonal contrast to capture the intricate texture and layered structure typical of vintage scientific botanical illustrations. The flower head is depicted centered, isolated, and with no background. See more
