花冠口
花冠喉,花冠下部的一个结构
两者都是生物学结构拉,找本植物学看看

花冠嘴

花冠口,花冠是一种车,相信你知道把corolla throat,是卡罗拉

花冠 卡罗拉

花冠嘴 花冠咽喉

corolla意思是卵冠; 花冠。丰田有款车也叫这个http://corolla.toyota.com.cn/
不过我认为没关系，是花冠喉部的意思
最新消息corolla mouth应该是一种花名叫花冠唇花，大概外国叫corolla mouth

花冠嘴

我在这里查了一下http://www.cvh.org.cn
是花冠的一个结构吧！

corolla mouth是花冠口，
corolla throat是花冠喉部。

看在什么样的句子中，如下：
Anthers inserted near mouth of corolla tube or slightly protruding.
inserted to 2 mm from mouth of corolla tube or somewhat protruding.

corolla就是花冠的英文名字,mouth就是嘴的意思~
你可以猜下了~
我觉得把他们翻译成“花冠嘴”最合适。我的理解就是把嘴巴嘬成花冠的形状，不知道这样解释觉得怎么样！
哈哈~如果是看小说遇到的，我想就是这个意思了！！！

Corolla is the overall structure of the petals of a flower taken as a group within the calyx. Normally the corolla is the most conspicuous part of a flower and of a bright colour other than green. The concept of corolla description is widely used in botany as a primary determinant of vascular plant identification. Alternatively the corolla may be considered as the inner whorl of the perianth structure. The role of the corolla in plant evolution has been studied extensively since Darwin postulated a theory of the origin of elongated corollae.[1]
澳大利亚的朋友跟我说这个:
i found this also.. "At the base of the banner, wings, and keel, the corolla is constricted into a narrow aperture, thus forming a constricted "mouth" at the top of a saccate tube "
