BOTANY 



The cornfields near Northampton occasionally show St. Barnaby's thistle {Centaurea 

 Solstitialii) and the hemp nettle {Galeopsh ipeciosa). 



Fox Hall Bog, on the Upper Lias clay, has yielded the butter wort [Pingukula vulgaris), 

 the grass of Parnassus {Parnassia pa/ustris), the pennywort [Hydrocotyle vulgaris), the marsh 

 thistle {Cnicus palustris), the marsh valerian {Valeriana dioica), the bog pimpernel {Anagallis 

 Unella), the marsh bedstraw [Galium uliginosum), the marsh speedwell [Veronica scutellata), the 

 marsh lousewort [Pedicularis palustris), the marsh arrowhead grass {Triglochin palustre), the 

 marsh orchis {Orchis latifolia), the fragrant orchis [Hahenaria conopsea or H. Gymnadenia), the 

 cotton grass [Eriophorum angustifolium), the compressed club-rush [Scirpus caricis, formerly 

 known as Blysmus compressus), the heath rush [Juncoides [Luzula] multijlorum), the sedges [Carex 

 pulicaris, C. flava, C. Hornschuchiana, C. paniculata and C. ecbinata), and the grasses (Molinia 

 varia and Sieglingia decumbcns), while Rosa mollissima Willd. [R. tomentosa Sm.) is in the 

 vicinity. 



Near Holdenby the marjoram [Origanum vulgare) occurs. This plant is remarkably 

 absent from a considerable area of the Great Oolite in the county ; probably its presence here 

 is determined by the occurrence of the drift which here obscures the Northampton sands. 

 This drift contains chalk and flints, and Origanum is especially fond of chalk or limestone soils.
