--><p><i>Sidalcea robusta</i> is one of the taller species of <i>Sidalcea</i> and can be distinguished also by its relatively long inflorescences with widely-spaced, showy flowers, its limited range, and its winged mericarps are notable. Rare and threatened by development, it is known from Butte County in the southern Cascade Range foothills and the northern Sierra <i>Nevada</i> foothills.</p>
