Hepatics in Portugal by W- E. Nicholson 



M 



account of our joint visit to Portugal in May 1911 (Rev. Bryol. 

 1912 p. 33 et seq.) so far as the mosses are concerned and he has 

 intimated that I Avoukl deal with the hepatics separately. I fear 

 lest the account which M' Dixon gave of the mosses may have led 

 bryologists to expect something equally novel and interesting 

 in reference to the hepatics, but except in the discovery of 

 Exormolheca pnslulosa Mitt, in some quantity and of some inte- 

 resting species of Riccia, there was little to parallel what we 



found among the mosses. 



The district explored has been sufficiently dealt with M^ Dixon : 

 The only region at all thoroughly examined was that portion of 

 the Serra deMonchique, including the points of Foia and Picota, 

 Algarve, which was readily accessible from Caldas de Monchiquc. 

 The whole of this district hes on a granite formation and this 

 coupled wdth the fact that May is rather late for hepatics in such 

 a southern latitude will account for the hepatic flora not being 

 very rich. Outcrops of limestone under not very favourable con- 

 ditions occurred near Lhc coast at Portimio and Silvcs, but these 

 only enriched Ihe list with MesopJujUa stillicidiorum. 



The most striking feature of the hepatic flora near CalJurf dc 

 Monchique was the predominance of the tlialloid species. Many 

 of these, such as Biccia Gougetiana, Grimaldia dichofoma, Tessel- 

 lina pijrainidala, Plagiochasma riipestre and others were suffi- 

 ciently obvious when we arrived, but it was not until some heavy 

 rain had moistened the parched and apparently bare soil that
