Flora of Preston and the Neighbourhood. Part III. By 

 Mr. Charles Joseph Ashfield. 



Our readers are referred to previous numbers of the ' Phyto- 

 logist' for notices of the Flora of Preston. The second and third 

 Parts are reviewed in the ' Phytologist' for September^ 1861. 



The following rare species, along with more common plants, 

 are reported in this the third part of the Preston Flora : — 



Hippurus vulgaris, Crocus vernus, Dipsacus fullonum, Pota- 

 mogeton rufescens, Primula farinosa, Convolvulus sejAum, Clay- 

 tonia perfoliata, Myrrhis odorata, Meum athamanticum, Bu- 

 pleurum rotundifolium, Convallaria multiflora, C. majalis, Me- 

 conopsis cambrica, Trollius europceus, Aquilegia vulgaris, Lamium 

 maculatum, Sartsia viscosa, Camelma saliva, Geranium colum- 

 binum, G. lucidum, Corydalis lutea, Tragopogon porrifolius, 

 Cichorium Intybus, Senecio Saracenicum, Verbascum Thapsus, 

 Epipactis latifolia, Carex fulva, Grammitis Ceterach, Botrychium 

 Lunaria. 



A few remarks on the above list will not be irrelevant; they 

 are partly addressed to our correspondent, the author of the list, 

 and partly to some of our readers, and it is the writer^s wish that 

 they may be useful to all who think them worth a perusal. 



Claytonia perfoliata has been reported as a naturalized plant 

 from many counties, and quite recently from Norfolk, Middle- 

 sex, and Lancashire. On the other hand, the perennial Clay- 

 tonia alsinoides has been reported from Derbyshire by Mr. 

 Baxter, from Perth by Mr. Sim, who finds it in more than one 

 place, and by a Glasgow correspondent, who has seen it near 

 the western metropolis. In all these localities the plant is said 

 to be a native, or to have all the accidents of a native plant. 

 No one has reported this as an apparently naturalized species, 

 though the more common one, C. perfoliata, has always been 

 reported as a semi-naturalized alien. 



The rose- or pink-coloured variety of Convolvulus sepium is a 

 Lancashire plant. It has been seen in Kent, at Aylsham, not 

 far from Maidstone, where it was observed in 1857. It is also 

 recorded as a variety by Sir W. J. Hooker, in his ^British 

 Flora,' third edition, 1834. 



Myrrhis odorata has been set among the aliens by a great 

 authority on phytogeography ; but those who are best qualified
