LIVERWORTS {Hepaticce) 



The history of botanical research in Norfolk as regards the Hepatics 

 or liverworts is on very parallel lines with that of the mosses. Briefly 

 put it attained a brilliant position in the early part of the century and 

 has been dormant ever since. This branch of botany found, in addition 

 to Hooker, Dawson Turner, etc., an indefatigable worker in the Rev. R. 

 B. Francis of Holt, whose careful search resulted in the discovery for 

 the first time in Britain of several species, and whose name has been 

 commemorated by Hooker in the British y ungermannice in the following 

 terms : . ' Jung. Francisci, Hook. About Holt and Edgefield. I gladly 

 take the opportunity of distinguishing the present species by the name of 

 its discoverer, my friend the Rev. R. B. Francis, who has so successfully 

 investigated the vicinity of his residence in search of the plants of this 

 genus, and has so kindly and liberally communicated to me numerous 

 specimens and much valuable information respecting them.' This 

 species is now known as Cephalozia Francisci. Other discoveries of the 

 same botanist were C. divaricata (Sm.), Lophocolea heterophylla (Schrad.), 

 "Jung, gracilis (Schleich.), and y. exsecta (Schmid.), all of which were 

 first recorded in Britain by this keen-sighted observer. 



The number of species at present recorded for the county falls short 

 of 45, which, out of a total of 220 as given in the most recent catalogue, 

 can only be considered as very inadequately representing the real distri- 

 bution of these plants.
