184 THE FLORA OF HALIFAX. 



Var. ampliretis, Dixon. Jouv. Bot., Feb. 1902, pp. 71-3. 

 1900. Crimsworth Dean.—/. Needham. A new- 

 British record. 

 This variety was described as a new species in 1893 

 by Limpricht under the name of Philonntis laxa, 

 founded on specimens collected near Lake Zurich. 

 By the aid of Dr. C. Warnstorf of Neu Ruppin, 

 Mr. Dixon has compared the Lake Zurich and the 

 Crimsworth Dean plants and established their 

 identity. In his " Note on Philonotis laxa, Limp." 

 in Journal of Botany, Mr. Dixon has shown that 

 the moss must be ranked merely as a variety of 

 P. fontanel, and he has named it ampliretis, as the 

 name laxa had already been given to another var. 

 of Philonotis.
