MOSSES. 83 



Wiltshire ; it is rarely found in fruit, so I account my 

 specimen a great treasure (Zygodon viridissimum, fig. 1 1 

 in cut). The Lapland and the Mougeot's Yoke mosses are 

 Alpine species, and the Lesser Yoke moss is chiefly an 

 inhabitant of Ireland. The Four-tooth mosses are two 

 peculiar little plants. The Pellucid one (Tetraphis pellu- 

 cida, Plate VI., fig. 11) has the secondary fructification in 

 leaflets formed in a cup. Its leaves are broad and closely 

 pressed to the stem, and its stems are matted together by 

 rusty fibres. I found a quantity of it closely clustered 

 between the decaying root of a tree and a mass of red 

 sandstone rock in the Chase wood, near Eoss. It grew like 

 a miniature forest on a mountain side, and its full green 

 hue and glossy lustre attracted my attention. Brown's 

 Four-tooth moss (Tetradontium brownianum) has leaves of 

 two kinds — the one broad and pressed to the stem, the 

 other mingled with them, but narrow and spreading. 

 Buxbaum's moss is entirely leafless, at least it appears so 

 to the naked eye. It resembles a fungus, its stem being 

 nearly buried in the earth, and only the reddish urn 

 appearing above. The leafy Buxbaumia rewarded our 

 perseverance in moss-hunting on one rather remarkable 

 occasion. We were passing two or three days at Cal- 

 lander, and the last day was devoted to an excursion to 

 the Leny Pass. It rained when we started, but having 

 once agreed not to remark on the weather during our 

 Highland trip, we only hoisted umbrellas in silence. On 

 we trudged, admiring the beautiful glimpses we got of 

 the mountain stream, and examining the wet banks in 

 the hope of finding some of our favourite plants. A gentle- 

 man was bent on seeing the country as well as we, and he
