The typical form of this species as described by Postels and 

 Kuprecht is nearly regular in outline, either oval ellipsoidal, or 

 very nearly globular. This is the plant figured by Kjellman 

 (1889, ])1. 7, f. 4, 5) and also, less typically, by Saunders 

 (1898, pi. 29, f. 4, 5) and distributed by the latter in 

 Collins, Holden and Setchell, P. B.-A., No. 417. The two 

 specimens noted above also belong to the type as it seems tons. 

 The more common northern form is the following. 



Soranthera ulvoidea f. difformis Setchell and Gardner f. nov.

 ularly so.
