Extract

The examination under the high power of the microscope of the walls of Heterodera cysts found on the roots of Agrostis stolonifera L. (Franklin 1938) showed the presence of rows of markings having the appearance of small punctations, and led to the tentative diagnosis of these cysts as H. punctata Thorne. By the kindness of Dr. Thorne the writer has been able to compare her cysts with some of Dr. Thorne's material, and has found that the surface markings have the same appearance. The writer would like here to acknowledge her indebtedness to Dr. Thorne for kindly lending his material. Cysts of several strains of H. schachtii have since been examined to find out if they also bear distinctive markings of any kind.
