NOTES ON THE FLORA OF LINCOLNSHIRE. 59 



always be discriminated from fen land species, found in N. and not 

 yet recorded for S., suitable habitats being very restricted : — Hyperi- 

 cum Elodes, SchoUera, Androyneda, Centunculus, Littorella if with us 

 still ; Empetrmn, extinct, I fear ; Epipactis paluHtiis, Habeuaria 

 bifoUa, Eleocharis midticaulis, Scirpus ccBspitosus, 8. Jiuitans, Ry)iclio- 

 spora alba, Eriophorum vaginatuin, if not extinct ; Carex elongata, C. 

 curta, C. Jilifonnis, if still with us ; Agrostis canina, Apera Spica- 

 venti, Descliampsia discolor, Festuca mijuros, Lycopodiiim inundatum, 

 L. clavatum, L. alpinum, Selaginella, Chara polgacantha. All now 

 rare with us, bordering on disappearance or extinct. 



Lime-loving species in N. not yet found in S. : — Thalictriun 

 coUinum, a species with a northern range, I imagine ; rare with us. 

 Rammculus sardous, widely spread. Stellaria nemorum, northern 

 type. Hypericum vwntanwn, in woods west of Brigg ; northern. 

 Veronica montana, Ophrys muscifera, Maianthemum, if a native ; Col- 

 chicum, north-west only. All rare and local. Some from the next 

 list might be added. 



Other species for N. not yet recorded for S. : — Cerastium semi- 

 deca7id7'um, Tri/oliumviaritimiim, Vicia lathyroides, Potentilla argcntea, 

 Chrysospleniuni alternifoUum ; the other species is found in S. 

 Selinum Carvifolia, a true native if there ever was one. Imda 

 Conyza, Bidens cerniia, the other species is found in S. as well as N. 

 Hypopitys, Lysimachia thyrsijiora, Orobanche major ^ a species I can- 

 not understand. Clienopodium murale, Atriplex Bobingtonii, A. 

 pedimculata, which has not been found for eleven seasons. Sali- 

 cornia appressa, once found; sp. Herb. Bennett. Salix ijentandra, 

 surely this must be for want of records ; it is so widely distributed 

 in N. Epipactis media ; Crocus midijiorus, very rare, river-borne 

 from Notts. (?). Juncus maritimiis, Potamogeton aculifolius, Scirpus 

 TaberncEmontani, S. rufus ; Carex pidicaris, not found for many 

 years ; C. distans, C. extensa, Spartina stricta, Melica nutans, 

 Asplenium Trichomaues, Polystichuni lobatum,, P, angulare, Chara 

 contraria, Tolypella glomerata, and Nitella opaca. Nearly all local 

 and rare. 



Species recorded for S. and not for N. : — Viola stagnina, Linum, 

 perenne, south-west only. Caucalis arvensis, practically confined to 

 the southern silt, but with a wide range there. Hypoclmris fuaculata, 

 on limestone only. Geniiana Amarella var. prcecox, the same. Antir- 

 rhinum Orontium, north-west, very rare. Melampyrum cristatum, 

 growing very rare indeed, only in south-west. S tacky s germanica, 

 if with us still. Herniaria glabra, local but common. Beta mari- 

 tima, if it is a true native. Thesium humifusum, on limestone ridge 

 nearly to Lincoln. Euphorbia amygdaloides, in the extreme southern 

 woods. Epipactis violacea, if the species is rightly named, on corn- 

 brash only. Potamogeton decipiens, P. angu^tifolius, Hordeum sylvati- 

 cum, and Tolypella prolifera ; mostly very rare and local. 



Species worth noting found in N. and S. : — Both varieties of 

 Spergula. Bupleurum. tenuissimum, Carum segetum, not uncommon. 

 Dipsacus pilosus, I do not understand the range of this species. 

 Se7iecio paludosus, this, though found in S., is practically only a N. 

 species. Pyrola minor, the only species we have ; it is growing
