80 SHACKLETON : DISAPPEARANCE OF YORKSHIRE PLANTS. 
named, and some of which are not now to be found within a radius of 
many miles of Keighley. The habitats given are all on the W. and 
N.W., and within two miles of the town. 
Habenaria bifolia. Grows in Sharp’s pasture on the road to 
Keighley. July ro, 18rr. 
Gymnadenia. conopsea. Meadows. Sometimes grows with 
O. maculata. July 12, 1810. 
Listera cordata. Grows in the swamp about 200 yards N. E. of 
the Tarn Gate. It is past flowering. July 6, 1811. In Blakey's 
Allotment, amongst the trees, pretty plentifully. It is just 
beginning to flower. May 18, 18 
a onek tenella. Grows in T. Moorhouse’s lowermost wood. 
lowers nearly white. Aug. 29, 1816. 
Conium maculatum. Grows on the roadside, near Blackhill. 
Aug. 4, 1810. 
Parnassia palustris. In ‘I. Moorhouse’s Wet Hill. Sep. 6, 1814- 
Narthecium ossifragum. Grows plentifully in the Tarn Allot- 
ment. July 24, 1800. 
Vaccinium oxycoccus. Common. Sep. 7. 1816. 
Primula farinosa. Grows in Midgley’s Wet Hill. Flowers light 
pm ay 25, 1805. (Has this species ever been recorded 
further south in Yorkshire ?) 
Pyrola media? Grows in the Long Wood, about midway down. 
August 1838. (About the year 1855 the present writer saw three 
or four plants in bloom at this station, but has not seen any 
since, though repeatedly searched for). 
Lythrum salicaria. Grows in Walker’s Bank Lane and Middle- 
brook’s Ing. September 1812. 
Orobanche major. Grows near the Beck, below Laycock. 
May 16, 1837. 
The disappearance of the above-named plants I attribute to, 
drainage and better cultivation of the land. 
The compiler of the Flora also collected various specimens of 
lichens growing in the district, many of which are no longer to be 
found there, and some survive in a depauperate condition. One— 
fertusaria letoplaca—has never, I believe, been recorded for the 
West Riding. I have three earn of this plant from three 
different stations near Keighley ; but it is now, I fear, extinct. 
I attribute the disedpeatenne of lichens to the ever-increasing 
smoke-density of the Airedale atmosphere.
