If the stem leaves be carefully removed and mounted the alar cells will be seen to be quite appreciably larger. Figure 65. Brachytheciuni rivulare X i; leaf and capsules X 10. than the others, although not so markedly so as in the Common Hypnum. The stems are often tall and stout, with a shrub-like habit. The capsules are not beaked and mature in autumn. If the seta be examined with a. high power lens it will be seen to be covered with fine papillse throughout. B. PLUMOSUM (Sw.) B. & S. grows on rocks in the bed of brooks, but is not submerged except at high water. The difference in habit alone is sufficient to distinguish it from B. rivulare; it is much smaller, darker green, more closely applied to the substratum, nearly prostrate, with acuminate stem leaves. The seta is papillose in the upper portion only. B. POPULEUM (Hedw.) B. & S. is a much more slender species growing on boulders, often near streams, but never on stones regularly submerged at high water. In this species the midrib runs to the very apex of the leaf, and the seta is papillose in the upper part Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Grout, Abel Joel, 1867-.
