On some New Hosts of the Stem Eelworm, Anguillulina dipsaci

Abstract

During the past two or three years the writer has had an opportunity of making observations on certain plants which are new hosts of the stem eelworm, Anguillulina dipsaci. In the present paper four such plants are dealt with, three of which are cultivated garden plants and one a common weed. Of the garden plants, one is a useful food plant, namely the parsnip (Pastinaca sativa L.) and the other two are Primulas, namely Primula pulverulenta Duthie and P. polyantha Mill, (polyanthus primrose). The weed is swine-cress or wart-cress (Coronopus Ruellii All., syn. Senebeira Coronopus Poir.)
