332 LINCOLNSHIRE BOTANY. [February, 



logy of the district^ and then we will pass on to the plants^ and 

 endeavour to keep to them. 



The chalk wolds form our highest ridge, but are very unpro- 

 ductive; in fact I have never found anything worth notice on 

 them except Scabiosa Columbcma and Orchis pyramidalis. 



Beneath the chalk we have two or three kinds of oolitic lime- 

 stonCj which produce all the rare plants we have^ except those of 

 the bogs and heaths situated on the gryphite limestone of the 

 Lias. I was going to say that I would not exceed a circuit of 

 six miles_, but I remember that I am stopped in one direction by 

 the Humber, which renders that term not exactly applicable. 

 To me^ and I dare say to many others, by far the hardest part of 

 writing a Flora, is the task of deciding what plants to include 

 among " the rarer plants," etc. There are several very interest- 

 ing and uncommon ones, as Ranunculus arvensis, Reseda Luteola, 

 Geranium sanguineum, Carduus nutans, Convolvulus arvensis, 

 Euphorbia eocigua, Car ex intermedia (Good.), Car ex riparia, 

 Glyceria rigida, etc., which cannot be included in a short paper, 

 — Avhich two last words have come home to me, and tell me I 

 ought to get to V70rk. 



It will perhaps be the most convenient method to divide them 

 thus : — 



I. Those found in Broughton Wood and the unworhed quarries 

 on its outskirts. — Anemone Pulsatilla, Aquilegia vulgaris, Acer 

 campestre, Euonymus europseus. Genista tinctoria, Astragalus 

 glycyphyllos and hypoglottis, Hippocrepis comosa, Spirsea Fili- 

 pendula, Bryonia dioica, Cornus sanguinea, Lactuca muralis, 

 Serratula tinctoria, Carduus pratensis, Erigeron acris. Campa- 

 nula latifolia, glomerata, and Trachelium, Ligustrum vulgare, 

 Polemoniura coeruleum [possibly an escape, though appearing 

 truly wild) , Teucrium Chamaedrys, Lamium Galeobdolon, Ophrys 

 aj)ifera and muscifera, Narcissus Pseudo-Narcissus, Convallaria 

 majalis, Tamus communis. Arum maculatum, Melica nutans, 

 Brachypodium pinnatum. 



II. Cornfield plants. — Sileue noctiflora, Specularia hybrida, 

 Linaria minor, Alyssum calycinum (I never met with more than 

 one plant of this or Jasione inontana) . 



III. Bog plants. — Drosera intermedia, Stellaria glauca, Hype- 

 ricum elodes, Hottonia palustris (which flourishes best in the 

 drainings of bogs, though found also elsewhere), Lastrea spi- 

 nulosa.
