I have never been able to perceive the differences between T. chlo- 

 ronotos and membranifolia insisted on in *Bryol. Europsea' {Bar- 

 bula, p. 18), and specimens of the former communicated by M. 

 Schimper from Avignon have the inflorescence monoicous, the stem 

 branched and the leaves membranous at the apex, precisely as in T. 

 membranifolia. In these specimens, as in Arnott's, Philippe's, and 

 my own from Bilheres, besides there being axillary male flowers on 

 the fertile plants, there are also separate male plants with terminal 

 flowers ; but I have seen no specimen of T. chloronotos with a truly 

 dioicous inflorescence.

This form, which, as the authors of ' Br. Europ.' remark, is found 

 only on a calcareous matrix, is sometimes scarcely larger than T. 

 muralis, and its habit is very diff'erent from that of the larger, ordi- 

 nary form of T. ruralis ; yet it seems impossible to separate it speci- 

 fically. I have the same form from Dr. Grateloup, gathered near
