苞

At the end of February, the bract attained approximately their full size, and a pair of anatropous ovules were initiated on the adaxial surface at the base of the fertile ovuliferous scale.

2月底，苞片体积不再发生变化，珠鳞膨大端的基部的近轴面分化出2个倒生胚珠。

Inflorescences villous and glandular pubescent along axis and bracts; corolla pale yellow or brown-yellow often tinged with purple; parasitic on species of Apiaceae

沿着轴和苞片的花序具长柔毛和腺状短柔毛；棕色黄的通常微染具的花冠浅黄的或紫色；在Apiaceae的种上寄生 25 Orobanche alsatica 多色列当

Corolla not club-shaped, lobes not apiculate; bracts not longer than calyx.

花冠并非棍状，裂片不具细尖；苞片不长于花萼。

Fruiting bracts appendaged near base at center or without appendages.

果苞片附属物近基部在中心或没有附属物。

Any of several weedy, chiefly biennial plants of the genus Arctium in the composite family, having pink or purplish flower heads surrounded by prickly bracts and forming a bur in fruit.

牛蒡任一种杂草，主要是菊科牛蒡属的两年生植物，开粉红色或略带紫色的花穗，并被带有多刺的苞所包围，形成果实中的刺果

Leaf blade abaxially pilose or sparsely pubescent; teeth along bract margins and sometimes along leaf blade margins aristate and with a claviculate apical gland; hypanthium outside basally pilose to subglabrous; sepals margin sparsely ciliate.

叶片背面具柔毛的或疏生短柔毛；沿着苞片边缘和有时齿沿着叶片边缘具芒并且具具卷须顶端腺体；基部在外面的托杯具柔毛的到近无毛；萼片边缘疏生具缘毛。 21 C。 dolichadenia 长腺樱桃

Autoecious:Having all stages of a life cycle occurring on the same host .

异苞同株的：全部生活史的各个阶段都在同一寄主之上发生的。

Leaf margin with 5-7 lobes on each side ending in 10-30 awns; blade glabrous or barbate; bracts of cupule glabrous; nuts mature 1 year after flowering

叶缘具5-7裂片在每边结束于10-30芒；叶片无毛的或具髯毛；壳斗的苞片无毛；坚果成熟的1 年花后 11 Q。 palustris 沼生栎

Inflorescence a condensed panicle or botryoid, each axis terminated by a flower, axillary or terminal on short lateral branches, few-flowered; bracts 3-lobed.

花序一凝结的圆锥花序或botryoid，一花，在短侧枝，很少花上的腋生或顶生结束的每轴；苞片3浅裂。

The number of leaf primordia was affected by both genotype and environment, while the numbers of bracteal, spikelet and floret primordia were affected mainly by environmental factors.

以平均热间距来衡量，适期播种处理的叶片、苞叶和小穗原基分化速率最高；而小花原基数与小花分化持续期之间的数量关系最为密切。
