Cleome isomeris Greene
Bladderpod Spiderflower, Bladderpod
Capparaceae (Caper Family)
Synonym(s): Isomeris arborea, Isomeris arborea var. angustata, Isomeris arborea var. globosa, Isomeris arborea var. insularis
USDA Symbol: clis
Extremely variable as to foliage and fruit, this ill-scented, evergreen shub is usually rounded, erect, widely branched and appoximately 4 ft. tall. The odd-smelling, yellow flowers are followed by curious pods that resemble paper lanterns. Lacy, gray-green leaves are palmately compound.
The species name comes from the Greek words isos ("equal") and meris ("part"), possibly describing the equal halves of the pod.
