--><p><i>Silene scouleri</i> is a very complex species that appears to be in the process of diverging into at least three different entities. Subspecies scouleri is a plant of the Pacific coast and lowlands. It has tall, stiffly erect stems, lanceolate to broadly lanceolate leaves, and a viscid inflorescence with many-flowered whorls of almost sessile flowers ranging in color from greenish white to rich pink. At the other extreme is <i></i>subsp.<i> pringlei</i>, a plant of the mountains in Mexico extending northwards into Arizona and New Mexico. It has slender, somewhat nodding flowering stems with very narrow leaves. The flowers are usually paired at each node and secund on slender pedicels about equaling the calyx in length. The petals are off-white, sometimes tinged with dusky purple. Between the two extremes is <i></i>subsp.<i> hallii</i>, a short, stocky plant of the Rocky Mountains and foothills with a few-flowered inflorescence. It has a larger, campanulate calyx, and some of the flowers usually become deflexed. Differentiation among these three forms is incomplete and plants indeterminate to subspecies are frequently encountered in areas away from the main distribution centers of the three subspecies. In northern Oregon and Idaho there appear to be populations connecting <i>S. scouleri</i> with <i>S. oregana</i>. They have some of the characteristics of <i>S. oregana</i> but not its laciniate petals. They may represent a more luxuriant form growing in taller vegetation, but their status needs further study.</p>
