The young sporophytes sometimes bend over towards the Hght until they are parallel with the incident solar rays, so that the young green capsules with their abundant assimilative tissue are equally illuminated on all sides. Such plants remind one very strongly of house plants in a window. Its spores mature in autumn. It is a most variable species in pretty nearly every character. These two species often grade into each other and the Dark Ditrichum is probably only a variety of the Brown. The Red Didymodon [D. rubellus (Hoffm.) B. & S.] some- what resembles the Dark Ditrichum, but is more red than brown and its leaves are two or three times as long and somewhat curled when dry. It belongs in the Tortula family, although evidently related to the Ditrichums. D. PALLIDUM (Schreb.) Hampe, the Yellow Ditrichum, is more abundant southwards and in the lowlands, and is much larger than the other two species. It is easily recognized by its bright yellow setae and unsymmetric capsules, which mature in late spring. It is most frequent in dry sandy 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-.
