1923] Pearson: Notes on a Collection of New Zealand Hepaticae 311 



Observations. — The general outline of the plant is like a Biccia; 

 the chief characters, however, being the pyriform calyptra, the upper 

 portion of which is densely papillose, with a very large corona and 

 the numerous radiating amentula on the branches. 



Riccardin alteriiiloha (Tayl.), the original specimens of which are 

 in the Manchester Museum and have been examined by me, has, 

 according to Stephani, two such similar characters, but it is quite a 

 different species with very large lobate fronds not unlike R. lohata 

 Schiffn.
