History, Use, Propagation, Culture, 
' 2234. Zygodon. From ivyog, a yoke, and bSus, a tooth, and so called, we presume, in allusion to the yoking 
together by pairs of the outer teeth ; but the name is unexplained by its authors. A singular plant, which was 
referred to Bryum by Dickson, and to Mnium by Smith. The stems grow in a tufted manner like Gymnos- 
tomum viridissimum, but rarely exceed half an inch in length. The peristome is double ; the outer consist- 
ing of sixteen short obtuse teeth approaching in pairs, which at length become recurved; inner of as many 
alternate cilize lying horizontally over the mouth of the theca. 
2235. Diphyscium. From 5/?, twice, and tpvirxiov, a vesicle, in allusion to the double nature of the shell of 
the theca. A little plant found in woods, and on rocks in alpine situations. The stems are exceedingly short, 
and grow in densely matted patches. The theca is large, ovate, gibbous, and oblique. Dr. Hooker denies the 
existence of a double peristome, while Hornsehuch asserts its presence. 
2236. Buxbaumia. A very singular plant, destitute of apparent leaves, and resembling a minute fungus 
rather than a moss. It was named in honor of John Christian Buxbaum, a German botanist, who published, 
in 1728, an account of the plants of Asia Minor in five centurias of figures of little merit.. This plant was 
originally discovered in the vicinity of Astrachan, afterwards in a fir-wood near Norwich, and lately in 
two stations in Scotland. Its minute size and want of foliage may have caused it to be overlooked. 
2237. Funaria. From funis, a rope, in allusion to the twisted nature of the strongly hygrometrical fruit- 
stalk. This genus, though sufficiently characterized by the interior teeth or cilijs being oblique and placed
