Koelreuteria bipinnata Chinese flame tree
Chinese lantern fruit capsules in late summer are more colorful than those of K. paniculata, goldenrain tree. See a handsome pair on Jane Stanford Way at the crosswalk southeast of the Knight Management Center. Half a dozen grow around the lawn and sand volleyball court of Willis Court at Rains Houses, but they have not been thriving. The two K. paniculata placed among them provide an opportunity to compare the species: K. bipinnata, of course, are the ones with bipinnate leaves, though other differences in leaflet size, shape, and margins may be observed.
Name derivation: Koelreuteria – after J.G Koelreuter (1733–1806), German professor of botany; bipinnata – bipinnate (the leaves).
