ABSTRACT
The plants which the author first received as Utricularia vulgaris from the New Forest in Hampshire and from Cornwall, and which the author have chiefly worked on, have been determined by Dr Hooker to be a very rare British species, the Utricularia neglecta of Lehm. Utricularia neglecta, the general appearance of a branch, with the pinnatifid leaves bearing bladders. Moreover, the quadrifids of Utricularia montana contain larger and much more regularly spherical, but otherwise similar, particles, which closely resemble the nuclei in the cells forming the walls of the bladders. A plant of Utricularia vulgaris, which had been kept in almost pure water, was placed by Cohn one evening into water swarming with crustaceans, and by the next morning most of the bladders contained the animals entrapped and swimming round and round their prisons. As the quadrifid and bifid processes offer one of the greatest peculiarities in the genus, the author carefully observed their development in Utricularia neglecta.
