MOSSES<br />

like plant appears much like the prothallium of the<br />

fern. Soon buds of young moss <strong>plants</strong> appear. On<br />

these the <strong>plants</strong> grow <strong>and</strong> produce spores which in<br />

their turn fall to the ground <strong>and</strong> grow into new <strong>plants</strong>.<br />

Roots will grow from any part of a moss plant that<br />

is kept dark <strong>and</strong> moist. Often roots <strong>and</strong> new <strong>plants</strong><br />

will grow from a leaf that is broken off. Mosses thus<br />

spread very rapidly.<br />

TREE MOSSES<br />

Do you remember that we said there were <strong>mosses</strong><br />

that looked like small trees? The picture shows you<br />

some of these. See what long roots they have. Do they<br />

not look like the slender creeping rootstocks of some<br />

<strong>ferns</strong> ? The little treelike <strong>plants</strong> come up from this<br />

underground stem in the same way that fern fronds<br />

spring up from their rootstocks. Because this moss is<br />

so much like little trees it is called tree moss.<br />

Notice how the stems bearing the capsules come out<br />

from among the green leaves at the side of the stem.<br />

There are quite a number of our <strong>mosses</strong> whose capsules<br />

grow in this way. The tree <strong>mosses</strong> are among the largest<br />

of these. The capsules nearly always st<strong>and</strong> up<br />

straight at the ends of their long stems. When young<br />

the capsules are green, but as the spores ripen they turn<br />

brown. The beak at the top has a long point. When<br />
