Note on Trichostomum Warnstorfii, Limpr. 



Correns in his studies on the vegetative propagation of 

 mosses has described and figured the brood-bodies borne 

 by this species, which thus far is unknown^n fruit. These 

 brood-bodies and the leaves are identical with those borne 

 by Pottia riparia Aust. Sull. Icon. Supp. t. 21 -and I have 

 reason to suppose that they are identical. Kindberg has 

 also recognised the similarity (Bryin. Eu. et Am. 2 ; 280. 

 1897) and described the species as « Didymodon ripanus 

 Austin », Austin had it in his herbarium under this name. 

 I have reason also to believe that Didymodon Macounii 

 Kindb is also the same species, and have so stated my 

 belief at the time that it was called Leptodontium Cana- 

 deme, Kindb. (Bull. T. B. CT, 19; 275. 1892.)
