Lees: An Old Leeds Herbary. 



545. Comarum palustre. Addle, June 1836. 



555. Poterium officinale. Shepherd's Pond, 1854. The 

 ground has- lately been built-over, but it still lingers in damp 

 ground within the rails of the Jowett estate, Harehills (1899). 



608. Chrysosplenium oppositifolium. Roundhay (on lower 

 lake), May 1836. I believe still (1898) at the 'waterfall' foot. 



610. Parnassia palustris. Thorp Arch, 1846, J. D. H. 

 623. Sedum acre. Kippax. 



633. Myriophyllum verticillatum. Knostrop, J. D. H. 

 Relegated now to dikes much farther afield. Appears to have 

 been the fine variety, pectinatum. 



644. Ly thrum Salicaria. Sheepscar beck, 1846. Long 

 gone, too, but up to 1870 or so there was a clump or two every 

 year in a marshy place by the same beck a mile higher up, just 

 at the foot of Sugarhills, by the path between Potternewton 

 and the old toll-bar-house on the Meanwood road. There were 

 specimens of the much rarer Lythrum Hyssopifolia in the herb., 

 but zmlocalised definitely, though it is not at all improbable it 

 grew in the same quaggy spot alluded to above. The unhand- 

 some Bidens tripartita grew by the goit at Sheepscar, near 

 Benson Street, up to 1889. 



[646. Epilobium angustifolium with Lathrsea squamaria, 

 localised Tinsley Park, 1839. The place is near Sheffield.] 



664. Hydrocotyle vulgaris. Addle. 



668. Sanicula europsea. Gipton Wood, 1840. 



670. Conium maculatum. The Hemlock. Burley Wood, 

 1839. 



704. (Bnanthe fistulosa. Water Dropwort. Swillington. 

 It is remarkable (to me) that there is no specimen of the much 

 more striking and poisonous Cowbane, CE. crocata, which (though 

 now nigh gone) was so fine and abundant (between 1867 and 1876, 

 at any rate) in the swamp below the Adel dam embankment. 

 Can it be that a longer and closer purview on the part of the 

 botanical eye would show that we have herein a completed 

 cycle of plant birth and death ? I am disposed to think so. 

 The natural stay of species may be long or short, as with 

 higher things. Twenty years may wipe out almost anything ; 

 and I suspect that nearly all Dr. Heaton's active botanising was 

 done in the earlier decades between 1835 and 1865. He was at 

 Adel — always spelled Addle — many times (as specimens prove), 

 but if the Cowbane was not there then he could not gather it.
