Mosses. 126 MOSSES WITH A HAND-LENS rule the Hooked Mosses are much larger than the true Hyp- nums and are seldom or never regularly pinnate. The leaves at the end of the branches are specially noticeable for their hook- like appearance. Mounted and examined with a high-power lens, the leaves will be seen to have a well developed midrib, which at once distinguishes them from those of the true Hypnums. The species of this subgenus are, perhaps, the most puzzling of any of the Hypnum Family and it is entirely useless to en- deavor to enable anybody to distinguish the species without the use of a compound microscope. Hypnum uncinatum Hedw., the species figured, is the most •common member of the subgenus. It is most frequently found on damp stones, more rarely on soil. The capsules are usually produced freely, maturilig in autumn. AMBLYSTEGIUM. Most Amblystegiums are very slender creeping mosses with capsules which are often disproportionately large and which usually take the peculiar position shown in Fig. 60, 31 and 32, when dry. This peculiar shrinking is not always present; it is lacking in A. adnahun which has been treated in connection. Figure 60. Plants of Amblystegiiiui serpens much enlarged. natural size capsules.
