the plant in question. The Roman numerals represent the month of flower- 

 ing, and whenever the mark of verification (!) is appended to any of the 

 stations of a plant, the time of flowering must he understood to apply 

 exclusively to Malhara and the immediate vicinity. In all these cases the 

 numerals indicate the extreme times within which the writer has actually 

 seen the plant in flower. The vertical limits are given in several cases 

 where they have been distinctly traced. The commoner plants are omitted. 

 Botanists are invited to communicate any corrections or noteworthy 

 additions. 



LIST OF PLANTS. 



KANUNCULACE^. 



Thalictrum mimis, L. The normal form is littoral. 



T. calcaremn, Jord. Grows near the top of Gordale ! 49. vii. 



T. fiexuosum, Reich ? {T. eminens, Jord ?) Gordale ! In some lists this is 

 styled T. majiis. The T. majus of Dr. Windsor's list (Phyt., N.S., i. 

 203.) is the same as the Gordale j^lant. vii. 



TrolUus europmus, L. Pastures above and below the Cove ! 49. vi-viii. 



Helleborus fcetidiis, L. I have a specimen which is said to have been 

 *' gathered below Malham Cove, 1839." No botanist of my acquaint- 

 ance professes to have seen the plant in situ. 29. 



ActcEa spicata, L. Gordale ! Top of Malham Cove ! " A few plants at 

 the side of the brook below Malham Cove," Dr. Windsor. 3. v. 



CRUCIFERiE. 



Thlaspi alpestre, L. Malham Cove. J. Tatham. Near Malham Tarn 1 

 " Very plentiful by the lead-mines betwixt Stockdale and Malham. 

 Although this jDlant varies somewhat in form, in the stalk being simple, 

 or more or less branched, etc., yet I respectfully submit whether the 

 T. alpestre and T. virens of Babington, notwithstanding his general 

 accuracy and very high authority, may not really be only slight varieties 

 of the same species." Dr. Windsor. The Malham plant is T. occita- 

 num, Jord. Probably all of Dr. Windsor's stations for T. alpestre 

 belong to this species. Has he not mistaken T. occitanum for T. 

 virens? The last-mentioned variety has not been found in Craven. 

 Jordan, and not Babington, is responsible for the division of T. 

 alpestre. 10. vii. 



Hutchinsia petrcea, Br. " On the higher part of the furthest east cliff in 

 Awes Scar, near Malham Tarn," Dr. Windsor. I have found this 

 plant at the height of 450 yards. 11. v.
