IdentificationPrickly Fanpetals is much like Arrowleaf Sida (S. rhombifolia), but the leaves are not rhombic but narrowly ovate or lance-shaped (widest towards the base). The pale to medium yellow flowers grow singly or 2-4 in leaf axils, the pedicels shorter than in Arrowleaf Sida and sometimes not obviously visible. Many plants have a short spine where the leafstalk meets the stem, but some plants lack them.
