Obs. — " C. lunidiefolia may be distinguished from C. bicuspidata 

 and comiivens, and from most of their allies, by the dioicous 

 inflorescence ; the small leaves, obtusely cloven to only ^ of their 

 length, and rather more closely reticulate ; the bracts far less 

 deeply cloven, and rarely into more than two segments ; but, 

 above all, by the Jle.shg jjerianth and ealgptra, the perianth being 

 3 cells thick below and 2 cells thick about the middle, and the 

 calyptra 3 cells thick cdmost up to the very apex : whilst both these 

 organs in C. hictispidata and comiwens consist throughout of but a 

 single layer of cells. Moreover, the perianth is merely denticulate 

 at the mouth, while that of C. conniveiix has the almost unique 

 character, among European Cephalozice, of terminating m long- 

 cilia ; the perianth of C. catenidata being merely ciliolate, or setose 

 at the apex. The purple spores of C. bicuspidata alFord an addi- 

 tional mark of distinction from C. luiiuhefoliar R. S. 



In 1893 I received the iollowing interesting note from Dr. 

 Spruce : " In writing for a set of my hepaticcTe, C. Delogne (who 

 has charge of the herbarium at the Brussels Bot. Garden) asked 

 for specimens of some of my British Cephcdozia and Lejeunece, which 

 I seiit him. I took the opportunity to ask if any specimens of 

 Dumortier's hepaticse were accessible. It would seem that 

 Dumortier left no herbarium of hepaticse, and there are only a 

 few specimens from him in the national herbarium, where, however, 

 he occasionally worked and annotated some of the specimens. 

 When I was studying the ('ephalozia' I wished very much for a
