NOTES ON THE FLORA OF LINCOLNSHIRE. 57 



present knowledge, it will bristle with facts interesting to the 

 botanist and agriculturist alike. 



My notes only refer to the species in the ninth edition of TJie 

 London Catalogue. It should be noted that the genera liuhus and 

 Bosa are wholly excluded from this review. 



The species recorded for the county of Lincoln, excluding the 

 exceptions named, reach the high total of 1108. Of these I regard 

 nineteen to be mistakes, twenty-five as very doubtful, and fifteen as 

 extinct now. If geological evidence is worth anything, about two 

 hundred are truly alien to the soils of Lincolnshire, though many 

 of them are native of Britain. For N. as many as 145 species are 

 recorded, which hitherto have not been met with in S. ; and for 

 S. 31, which have not been recorded in N. The varieties on record 

 number 150, excluding anomalies and colour forms, some of which 

 are very interesting. The hybrids are 16. 



By mistakes I mean species recorded in print which, on being 

 traced to the specimens, were found mis-named, or for which there 

 was practically other proof of error, as the incompetency or general 

 carelessness of the author who is the first and only authority. I 

 fear many from the doubtful list should be added to the mistakes. 

 The mistakes are : — Cardamine iinpatiens, Viola lactea, Cerastiiuii 

 alpinum, Hi/pericniii Androsamum, Medicago miniyna, Sednm roseum, 

 Crithmum inaritimuin, CEnanthe pirn pbiello ides, (E. silaifolia, Pyrola 

 rotundi/olia, Sibthorpia, lllecehriim, Suceda fruticosa, Orchis purpurea, 

 Aceras anthropopJiora, Asparagus ynaritimus, Allium sibiricum, Erio- 

 caulo7i, and Eriopliorum latifolium. The doubtful species are : — 

 Draba muralis, Thlaspi peifoliatiim , Cranibe, Dianthus glaucus, D. 

 C(Bsius, Foenivuluin, Galiuin anglimim, Inula crithmoidcs, CrepisjMludosa, 

 Mentha Pulegiuin, Thymus Cham/Edrgs, Calamintha parvijiora, Chemo- 

 podium vulvar ia, C. hgbridum, C. iirbicum, C. botrgodes, Polygojiuiii 

 viviparwn, Allium, Schcenoprasum, Juncus acutus, Elisma natans, 

 Damasonium, Carex teretiusctda , Phegopteris calcarea, Eguisetum 

 hgemale, and Lycopodium Selago. 



The following species are now almost certainly extinct in their 

 former habitats. There is abundant evidence that they formerly 

 flourished with us, either from localized specimens, or the records 

 of absolutely trustworthy authorities : — Silene maritima, 8. quinque- 

 vulnera, Lathgrus maritimus, Cicuta virosa, Senecio paludosus, S. 

 pahistris, Sonchus palustris, Schollera, Hgpopitgs, Statice reticulata, 

 Limosella, Utricidaria minor, Malaxis, Liparis, and Lycopodium. 

 alpinum. 



These have all passed away before a changing environment. The 

 list is being added to gradually but surely. I fear we have lost Frosei a 

 anglica, Peucedanum palustre, and others, in the last few years. 



The only hybrids of any special interest are : — Cnicus lanceo- 

 latus X pratensis. — Mr. Arthur Bennett, to whom I desire to return 

 most sincere thanks for many kindnesses and much help, agrees 

 with me about it. The only specimen there is is in the County 

 Herbarium. CampamUa latifolia X TracheUum. — Specimens in County 

 and Bennett Herbaria; the best in Mr. Bennett's. Carex distansx 

 fulva, in County Herbarium.
