 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. Among the interesting species not previously mentioned as occurring in the district are [Cammarum hyemale, Greene (Eranthis, Salisi.)] Lepidium hetcrophyllum, Benth. var. crinigerum, Gren. & Godr.
