 occurred in the almost innumerable tufts I have examined in their

On the mode of action of Heat upon Plants, and particularly the 

 effect of the Solar Rays. By M. Alphonse De Candolle. [Transla- 

 tion from the Bibliotheque Universelle de Geneve, March, 1850.] 



Note on Viola stagnina. By Charles C. Babington, M.A. [To the 

 other characters by which Mr. B. would distinguish this plant from 

 V. lactea of Smith, he adds that " of a slender rhizoma, spreading ra- 

 ther extensively through the peaty soil which the plant inhabits, and 

 sending up at short intervals what have the appearance of being dis- 

 tinct individuals."] 



Remarks on Mentha sativa and gentilis of Linneus. By Dr. C. J. 

 Hartmann. [Translation from the 'Flora' of January 28, 1850. 

 Dr. Hartmann contends that Fries has misapplied the Linnean 

 names of these plants, and that the nomenclature is thus : M. sativa, 

 Linn. = M. gentilis, Fries. ; M. gentilis, Linn. = M. rubra, Fries. ; 

 M. Aghardiana, Fries. = M. sativa, Fries.] 



On Sagina apetala, L. and S. ciliata, Fries, with some remarks on 

 the mode of discriminating species. By Arthur Henfrey, F.L.S., &c. 

 [Mr. Henfrey concludes the latter of these to be a variety of S. ape- 

 tala, not a species permanently distinct from it. His grounds for this 

 conclusion appear to be sound and sufficient, but must be consulted 

 in the original.]
