By Dr. Hooker's remarks in his British Flora, at p. 123, my attention has been recalled to a plant of common occurrence on the banks of Tyne and the other rivers in this neighbourhood, which, from Smith's description, and Sowerby's figure at 2213, of the English Botany, and in the Medical Botany, t. 267, I had considered as the Hemlock Water Dropwort, overlooking the circumstance, that Oenanthe crocata has a yellow juice. Lamarck and De Candolle, in their Flora of France, Woodville, in the Medical Botany, and Dr. Withering, in his Arrangement of
British Plants, make no mention of this yellow fluid, but Sprengel, in his edition of the Systema Vegetabilium, i. 889, when speaking of the plant says, "Succo luteo venenoso scatet;" and when he describes the succeeding plant, Oenanthe apiifolia, adopted from Brotero's Flora Lusitanica, he adds to a description which, with the exception of the stem being smooth instead of furrowed, might answer for either species, "Succo nullo peculiari gaudet." Certain it is, that in this particular, the Water Dropwort of our district resembles the Portuguese plant, but whether it be identically the same, I cannot take upon me to say for want of authenticated specimens of the Celery-leaved Water Dropwort.In the dene at Halton Castle, N.
Near Chillingham, N.—Mrs. Langhorne, in Berwick Flora.
This plant, which is notenumerated in Ray's Synopsis of British Species, grows in considerable abundance on the flat Basaltic rocks between the Roman Station at Wall-Town and the Crags, near an ancient well called the King's Well, N.
