Didymodon cordatus Jur.— Vineyard walls ‘near Aigle, usually 
near the base of the wall with abundant gemmæ. — D. rubellus

plant, but very well marked in its vegetative characters with 
broad plane margined leaves, strongly serrate above. — D. ruber 
Jur. Moist rocks crevices at an altitude of about 8 000 feet, Roc de 
la Vache above Zinal. : 
Barbula icmadophila Schp.—Rocks by the Navigenze near Ayer, 
a curiously fragile form.— P. paludosa Schleich. Moist crevices in 
rochs near Zinal with gemmeæ. ne 
Leptodontium styriacum Limpr. — Not uncommon on the 
rotten wood of the chalet roofs both at Zinal and Grimentz. It 
might readily be overlooked as an undeveloped form of some 
other moss, but the serrate leaves and the gemmæ which are very 
abundant on the less luxuriant forms can readily be seen with a 
pocket lens. In this, L. flexifolium Hpe and Z. gemmascens Braith. 
we have an example of three very closely allied species, which are 
readily separable by their very different methods of gemmiparous 
_ reproduction.
