of Zygodon by the elon mgete, 4 filiform, subrigid stems, bright yellowish-green 
colour, triquetrously set, ely ovate-cordate, shortly pointed leaves, 
densely and highly apices throughout on both surfaces. The fruit

Among a number of duplicates of New Zealand mosses sent me from

Certain species of ‘Tortula (§ Syntrichia) with large recurved denticulate 
leaves might in absence of fruit be taken for it, but they would be recog-
