Do Macropidia and Crescentia only produce flowers?
Crescentia Crescentia (calabash tree, huingo, krabasi, or kalebas) is a genus of six species of flowering plants in the family Bignoniaceae, native to southern North America, the Caribbean, Central America and northern South America. The species are moderate-size trees growing to 10 m tall, and producing large spherical fruits, with a thin, hard shell and soft pulp, up to 25 cm in diameter.
Ranunculus Ranunculus is a genus of about 500 species (Ranunculaceae)] of plants in the Ranunculaceae. Members of the genus include the buttercups, spearworts, and water crowfoots. The petals are often highly , especially in yellow species, owing to a special coloration mechanism: the petal's upper surface is very smooth causing a mirror-like reflection. The flash aids in attracting pollinating insects and temperature regulation of the flower's reproductive organs. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds.
