but in general the pentanclrous flowers and semimembra- 

 nous bracts will sufficiently distinguisb the present from 

 the preceding species, although the quinary or quaternary 

 division of the flowers is not altogether constant. The 

 stations of C. tetrandrum and its varieties have been more 

 carefully recorded, apparently under the idea that it is 

 the rarer of the two species ; but if there is any decided 

 difference between their census, perhaps C. semidecan- 

 drum may prove to be the less common, at any rate, in 

 the northerly provinces. (See vol. i. page S28.) 



Malva verticillata, Linn. 



Area (6). 



Alien. Found in corn-fields, in the parish of Llanelly, 

 Caermarthenshire, in 1843 and some subsequent years, by 

 Mr. James Motley ; doubtless introduced thither by some 

 chance or accident, but how or by what means there would 

 seem to have been no clear clew to determine. (See Eng. 

 Bot. Supp. No. 2953 ; Phytologist ii. 973.) 



Malva Nic^ensis. , ^;^ 



Area (3). 



Alien. Some few specimens of this species were found 

 by Mr. Thomas Moore in " Battersea Fields, on the em- 

 bankment opposite the Chelsea Botanic Garden". As 

 implied bj^ the name, it is a species of southern Europe, 

 which occasionally appears in more northerly countries, 

 through the accidental introduction of its seeds. It has 

 thus been introduced into Denmark with marble from 

 Italy.
