Horsetails and tree ferns grew to heights of fifty feet, club mosses to a hundred and thirty.

杉叶藻桫椤长到l5米高度，松长到40米高度。

Like, lycophytes were huge three hundred million years ago — literally.

比如，3 亿年前，松植物是巨大。

He divided the mosses into six genera: Mnium, Hypnum, Polytrichum, Bryum, Sphagnum and Lycopodium — classifications that are useful today.

他把藓类分为六个：提灯藓、灰藓、金发藓、真藓、泥炭藓松，这些分类在今天仍然有用。

It was a lovely soft September afternoon — a day to lie under a Roman stone-pine, with one's eyes on the sky, and let the cosmic harmonies rush through one.

那是一个可爱而九月午后——一天躺在一棵罗马松下，双眼望着天空，让谐在其中奔腾。

This is because scale trees were a type of plant called lycopods, which originated way back in the Silurian Period -- before seeds were even a thing!

这是因为鳞木目是一种称为松类植物，它们最早出现在志留纪——那时种子都还没出现呢！

The bugs in question can be curbed by adding either of two substances to cattle feed, a chemical called 3-nitrooxypropanol, or a seaweed called Asparagopsis taxiformis.

所讨论这些细菌可以通过向牛饲料中添加两种物质中任意一种来控制，这两种物质分别是名为3-硝基氧丙醇化学物质或名为松类红藻(Asparagopsis taxiformis)海藻。

But lycopods were also the earliest vascular plants, which means they were the first plants to contain xylem, a special tissue that moves water and nutrients from the roots to the leaves.

但是， 松类也是最早维管植物，这意味着它们是第一批含有木质部植物，木质部是一种特殊组织， 负责将水分养分从根部运输到叶子。

Some lycopods are still around today, like the low-lying, water-loving club mosses and quillworts.

一些松类植物至今仍然存在，比如低矮、喜水卷柏瓶尔小草。

But it did just fine feeding on the seed ferns and lycophytes that were common during the Triassic, no teeth required.

但它在三叠纪时期以常见种子蕨松为食，完全不需要牙齿。
