In other orchids the threads cohere at one end of the pollen-masses; and this forms the first or nascent trace of a caudicle.

在其他兰花中， 线状物聚集在花粉团的一端； 这形成了一个核心的第一个或新生的痕迹。

A pollinium, when highly developed, consists of a mass of pollen-grains, affixed to an elastic foot-stalk or caudicle, and this to a little mass of extremely viscid matter.

高度发育的花粉由大量花粉粒组成， 附着在有弹性的足柄或叶柄上， 而这又是一小团极其粘稠的物质。

That this is the origin of the caudicle, even when of considerable length and highly developed, we have good evidence in the aborted pollen-grains which can sometimes be detected embedded within the central and solid parts.

这就是叶柄的起源， 即使在叶柄相当长且高度发达的情况下，我们在花粉粒的败育中也有很好的证据， 有时可以检测到花粉粒嵌在中央和实心部分中。

With respect to the second chief peculiarity, namely, the little mass of viscid matter attached to the end of the caudicle, a long series of gradations can be specified, each of plain service to the plant.

关于第二个主要特征， 即附着在茎端的少量粘性物质，可以指定一长串等级， 每个等级都对植物有明显的作用。
