A black and white botanical line drawing of several oval seeds with longitudinal ridges and stippled shadows on a white background.

A black and white botanical line drawing in horticultural style focusing solely on a small cluster of yarrow seeds (Achillea millefolium). Depict multiple small, dry seeds approximately 1 to 2 millimeters long, with an oval to slightly elongated shape that tapers somewhat at one end (the hilum) and broadens at the opposite side. The seeds have narrowly winged margins that are thicker in the middle, creating a subtle flattened profile. Illustrate the seed coat surface as smooth with fine longitudinal ridges or delicate linear patterns. The seeds are compressed and hairless, lacking any bristles or feathery plumes. Arrange the seeds loosely in a natural, slightly scattered pile with visible spacing, emphasizing clear, precise linework and strong tonal contrast to highlight the seeds’ detailed texture and form. The drawing should be centered and isolated, without any leaves, stems, flower parts, or background. See more
