General Information

Ivesia webberi is a member of the Rosaceae (rose family). It is a low, spreading, perennial forb up to 9.8 inches (in) (25 centimeters (cm)) across with greenish-gray foliage and dark red, wiry stems (Figure 1). The 1.2–2.8 in (3–7 cm) long leaves are mostly clustered around the base of the stems, with 4–8 pairs of leaflets crowded at the tip, and are generally covered with long, silky grayish hairs. The inflorescence is a capitate or subcapitate cyme (i.e., a flat-topped inflorescence in a head-like or head shaped cluster) with 5–15 flowers per group. Flowers are about 0.4 in (10 millimeters (mm)) across and bright yellow with 5 stamens and petals that are much smaller than the sepals. The whole plant becomes reddish-tinged late in the season. Flowering typically begins in May and extends through June (Witham 2000, p. 9; Ertter 2012; http://ucjeps.berkeley.edu/cgi-bin/get_IJM.pl?tid=29467, accessed November 5, 2012).
