24 M. FOSLIE. NEW MELOBESIEAE. [1900 No. 6] 



large sorus with almost whorled orifices. The sporangia are four- 

 parted with a very short foot, about 110 //. long by 55 />-. 



The species grows on the leaves of Cymodocea antarctica and 

 is hitherto only known from the southern coast of Australia, gathered 

 in Port Phillip, Victoria, by Dr. F. v. Muller according to speci- 

 mens in berb. Pro f. N. Wille. Specimens long ago received from 

 the late Prof. Areschoug labelled Victoria are probably from the 

 same locality as the above.
