The target that each of those billions of pollen grains aims for is the naked ovule of another plant of the same species.

数以亿计的花粉粒中，每个花粉粒瞄准的目标都是另一颗同类植物裸露的胚珠。

This new research has found out that they do this because pollinator offspring developing in the outer ovules are at high risk of attack by parasitic wasps.

这一新的研究发现，他们这样做，是因为授粉后代发展的外部胚珠是高风险的攻击寄生蜂。

Ovary 5-18-loculed; ovules 1 per locule; styles as many as carpels, slender; stigmas capitate. Fruit a schizocarp, oblate; mericarps 5-18, indehiscent, reddish brown, horseshoe-shaped with a prominent ventral notch, sometimes 2- or 3-cuspidate.

Microspore Ye as the feather, small sporophyll sac formed by the polymerization, each polymer capsules formed by four small sporangia, small spores with dual airbags, and airbag Pinaceae pollen is similar to large sporophyll from the central axis and arranged in Brachypodium feather composition, Each Yibing has a shell bucket, each bucket containing shell upright ovules 10-12 months.

小孢子叶枝为羽状，小孢子叶由聚合囊组成，每个聚合囊由4个小孢子囊组成，小孢子具双气囊，与松科植物花粉的气囊相似，大孢子叶由中轴及羽状排列的短柄组成，每一柄上有一个壳斗，每个壳斗内有10—12个直立的胚珠。

Female flowers: sepals 5, often narrower than in male, imbricate to reduplicate-valvate, persistent, sometimes accrescent; petals 5, smaller than in male, mostly reduced or obsolete; disk annular or dissected, receptacle often villous; ovary 3-locular; ovules 1 per locule; styles 3, longer and slender, free or nearly so, once to several times bifid.

雌花： 萼片5，通常比雄花的狭窄，覆瓦状到外向镊合状的镊合状，宿存，有时增大；花瓣5，小于雄花，多数退化或废退；花盘环状的或多裂，花托经常具长柔毛；子房3室；胚珠每室1；花柱3，长和纤细，离生或近离生，1到数个2裂。

Inflorescences mostly lax, rarely capitate, always without clearly defined involucral bracts; ovules basal, anatropous.

多数疏松，很少头状的花序，总是没有明显确定的总苞片；基部的胚珠，倒生。

Disk pulvinate. Gynoecium (2 or)3-5-carpelled; ovaries connate in ± their basal half, otherwise contiguous; ovules few or several per locule; style lateral, of (2 or)3-5 contiguous or connate stylar elements; stigma punctiform or capitellate.

花盘枕状；雌蕊群(2或)3-5心皮；在多少里合生的子房他们的基生一半，不这样邻接；每子房室胚珠少数或数个；花柱侧生，具（2或）3-5邻接或合生的花柱单体；柱头点状或小头状。
