B. Male and female flowers grow on the same plant.

B. 雄花和雌花长在同一株植物上。

The female flowers are about three-eighths of an inch long, pale green, and grow in countless thousands on the ends of sprays.

雌花长约八分之三英寸，呈淡绿色，在花束的末端长出无数。

The male flowers are on the tassel; the fine silk threads which surround the ear, and peep out from the end of the husks, are the female flowers.

而那种围绕着包谷生长并在包皮的末端隐约露出的丝一样的细线，就是雌花。

The weather had been cold and boisterous and therefore not favourable to bees, nevertheless every female flower which I examined had been effectually fertilised by the bees, which had flown from tree to tree in search of nectar.

天气寒冷而喧闹， 因此对蜜蜂不利， 但我检查过的每一朵雌花都被蜜蜂有效地授粉， 蜜蜂从一棵树飞到另一棵树上寻找花蜜。
