Among the genera about which there has been some co i\ 



Calycularia. C. radiculosa, an interesting species of the Malayan n 

 was recently studied (Campbell (2|), and it wax demonstrated that it 

 has much in common with Blyttia and Morkia. with which it is doubtless 

 related. Schiffner [3] even thinks it should be transferred to the genus 

 Morkia and entirely separated from the other members of the genus Caly- 

 cularia. 



While it i> still too soon to propose a definitive- classification of the 

 thallose Jungermanniales, it may be said that so far as the two families 

 Aneuraceae and Blyttiaceae are concerned, the differences between them 

 are not of sufficient importance to warrant the establishment of two 

 families.
