MOSSES WITH A HAND-LENS 197 Sessile, without any stalk, like the leaves of all the mosses or the capsules of Webera. Segments. See under peristome. Seta, the stalk on which the capsule is borne. (Figs. 6 and lo.) Sigmoid, curved like the letter S. Spermatozoid. See antherozoid. Sporangium, often applied to the capsule, but by some authors restricted to the spore sac, or inner sac of the capsule containing the spores. Spores, small round bodies contained in the capsule, serving the purpose of seeds, but in no way homologous with them. (Fig. 27.) Sporophyte or sporophore, the spore-bearing part or genera- tion. In mosses it consists of the seta and capsule and constitutes the so-called fruit. Sporogonium, the sporophyte or spore-bearing part of the moss. Squarrose, spreading at right angles from the stem. Stegocarpous, having the capsule operctilate. Stipitate, having a short stem. Applied to antheridia and archegonia. Stolonifcroiis stem, a slender creeping stem with minute leaves. Stomata, pores in the surface of the thallus of the True Liverworts. Striate, marked with striae or slight furrows. Struma, a goiter-like swelling on one side at the base of the capsule. (Fig. 8.) Strumose, having a struma. Substratum, the material upon which the plant grows. Succuhous, with the upper margin of one leaf lying under the leaf next above. (See Plagiochila.) Sulcate, deeply furrowed with longitudinal channels. As applied to leaves, both striate and sulcate really refer to the fold whose concave surface is on the inner or ventral surface of the leaf. Of the capsule, deeply furrowed. (Fig. 17.) Synoicous or synoecious, having the male and the female organs mixed together in the same cluster. (Fig. 25.) Terete, circular in cross-section. Thallus, a broad, flattened plant form taking the place of. Please note that these images are ext
