resemblance to V. olitoria, from which it is scarcely distin- 

 guishable but by its fruit, renders the detection less easy." 



" Without pretending to decide the point, T incline 



to the belief that V. carinata holds the same relation to V. 

 olitoria as V. Auricula does to V. dentata, and that the 

 value of each as distinct species is, to say the least, very 

 problematical." (Phytol. iii. 428). V. carinata has been 

 recorded from provinces 1, 3, 5, 7. (See Bot. Gaz. i. 109).

Colonist. Agrestal. The provinces of the Lakes and 

 West Highlands have been added in the estimate above, 

 since probability seems to be rather in favour of, than 

 against, the occurrence of the species there. Though cer- 

 tainly found in some few spots beyond the latitudinal line 

 of 57, and therefore just within the superagrarian zone, 

 this is most likely the case only by agricultural introduc- 

 tion. Fedia Auricula has been recorded from provinces 1, 

 2, 3, 5, 6, 10, 15. " We have only to conceive the two an- 

 terior barren cells of V. dentata to become inflated, and
