And now we come to a minor balsa mystery . Why does the tree flower at night ?
现在让我们来揭开一个关于巴尔沙树的小小谜团:为什么它们会选择在夜里开花?
The balsa tree bursts into bloom at sunset during panama 's dry season , feeding a kaleidoscope of species .
巴拿马的干旱季,巴尔沙树会在日落时分开满鲜花,为各种动物们带来了口福。
There are angel wings made out of balsa wood , and worms encased in a bodice of molded plastic .
西印度轻木是天使之翼,模型塑料的紧身上满是蠕虫……
Over the course of a single night a flowering balsa tree may synthesize a quart or more of its signature nectar , a complex mix of sugars and aromatic compounds that has yet to be chemically parsed but that to this casual dipper tastes approximately like sweet syrup of mushroom .
