BOTANICAL NOTES— MAINLY FROM THE COLNE 



VALLEY.- 



WM. FALCONER, 



Slaithwaite, Huddefifield. 



The increase of tillage in the Colne Valley has led to the 

 appearance of several agrarian weeds, previously absent, most 

 of them common, but a few more unusual, viz., Galeopsis. 

 versicolor Curt., patches amongst the plentiful G. tctrahit L., 

 in one or two fields about Slaithwaite, Medicago denticulata 

 Willd. in flower and fruit amongst oats at Holthead (800 ft.), 

 Lcpidium sativum L. at Polega.te and Bupleitrnm roiitndifolium 

 L. in a garden at Wood Nook. Solitary examples were seen 

 of Linnm angiistifolium Huds. by the roadside at Barrett 

 Clough Head and Lepidiiim campestre R. Br. on waste ground 

 at Kirkburton (Fenay Valley). These are mere casuals with 

 no probability of establishing themselves, but Bidens tripartita 

 L. and Lycopiis europaeus L., whether due in the first instance 

 to canal traffic or man, have in recenl; years spread and increased 

 along the course of the canal between Huddersfield and Low 

 Westwood (Golcar). Acorns calamus L. maintains its station 

 at the side of Ramsden Mill dam (not, I am told, the ' Milns- 

 bridge ' of Lees' Flora), where also and at Pearson's dam and 

 New Close (Slaithwaite) Scutellaria galericulata L. may still be 

 found in plenty. A few others, once probably more or less 

 abundant, are now almost extinct, and the locahties, therefore, 

 are not particularly defined. The sundew {D. rotnndifolia L.) 

 grows in two spots in the Colne Valley, in one of them certainly 

 planted ; the beech fern in the Slaithwaite area and near 

 Meltham ; the oak fern in the Golcar area. Adder's-tongue fern 

 is found at Wilberlee and Wood Nook and remains unnoticed 

 and undisturbed, owing in some measure to its resemblance to
