Taxonomy Agalinis auriculata was first described by the renowned American botanist Asa Gray in 1849. The genus name "Agalinis" is derived from the Greek words "agalos," meaning "adornment," and "inis," meaning "belonging to." This name alludes to the stunning appearance of the flowers. The species name "auriculata" is derived from the Latin word "auricula," which means "earlobe" or "ear." This epithet refers to the distinct ear-like lobes at the base of the flower's corolla. Physical Appearance Agalinis auriculata, commonly known as the Eared False Foxglove or Purple False Foxglove, has a distinctive and charming physical appearance. Let's explore its morphology in detail: Stem: The stems of Agalinis auriculata are slender, erect, and typically unbranched. They rise from the ground and can reach an average height of about 30 to 60 centimeters (12 to 24 inches). The stems are often green or reddish in color, providing a supporting structure for the plant. Leaves: The leaves of Agalinis auriculata are arranged oppositely along the stem. They are narrow, linear to lanceolate in shape, and have a smooth or slightly toothed margin. The leaves can measure approximately 2 to 6 centimeters (0.8 to 2.4 inches) in length. They possess a green coloration, contributing to the overall foliage of the plant. Flowers: The most striking feature of Agalinis auriculata is its beautiful flowers, which are borne in loose clusters emerging from the axils of the upper leaves. Each flower is tubular in shape and measures about 2 to 3 centimeters (0.8 to 1.2 inches) in length. The corolla, or petals, of the flower consists of two lips. Upper Lip: The upper lip of the corolla is two-lobed, forming a distinctive hood-like structure. It can be various shades of pink or purple, adding vibrancy to the overall appearance of the flower. Lower Lip: The lower lip of the corolla is three-lobed and extends downwards. The lobes are often slightly reflexed, giving the appearance of a landing pad for visiting pollinators. The color of the lower lip matches the upper lip, creating a harmonious color scheme. Corolla Base: The base of the corolla holds a unique characteristic that gives the plant its common name, "Eared" False Foxglove. At the base, there are two prominent lobes that resemble small ears, hence the epithet "auriculata." These lobes add a distinctive touch to the flower's visual appeal. The overall coloration of the flowers can range from pale pink to deep purple, captivating observers with their vibrant and alluring hues. The tubular shape of the flowers, combined with the color and the prominent ear-like lobes, makes Agalinis auriculata a visually stunning and easily recognizable plant species. It's important to note that the physical appearance of Agalinis auriculata can vary slightly within its range, and individual plants may exhibit some variations in leaf shape, flower size, and color intensity.
