Schizolobium parahyba
Guapiruvu, Brazilian Fern Tree
Odd-looking flowering tree to 100′. Foliage even-pinnate, fine, grey-green, held fern-like at ends of branches; flowers yellow, Caesalpinia-like, in long erect terminal
panicles; fruit a 6″ teardrop-shaped papery pod holding a single flat yellow-brown seed that gives a satisfying clink when struck against a hard surface.
