Valeriana macrocera, also classified as Plectritis macroptera subsp. macroptera, is a species of flowering plant in the honeysuckle family. It is known by the common names longhorn seablush and white plectritis. This species is native to California and Nevada in the western United States, where it grows commonly across mountains, valleys, open steppe, and coastal habitat types. It is an annual herb that grows erect, reaching a maximum height of 60 to 80 centimeters (24 to 31 inches). Its leaves are widely spaced, arranged in opposite pairs, and are oval or somewhat oblong in shape with smooth edges. They can grow up to 4.5 centimeters (1.8 inches) long by 2 centimeters (0.79 inches) wide, and the upper leaves on the stem do not have petioles. The inflorescence is a dense, cylindrical, head-like cluster of flowers that range in color from pale pink to white. The corolla is less than a centimeter long, divided into five lobes, and ends in a short, blunt spur.
