Abstract
DURING the examination of a Hippeastrum plant the roots of which were badly attacked by a new species of the nematode genus, Rotylenchus, to be described elsewhere, it was noticed that some of the undamaged parts of the roots were covered with root hairs right up to the base of the bulb. Closer examination showed that the root hairs were of secondary origin, for in some cases the root was still surrounded by the original hypodermis, which was partially sloughed, and the new root hairs were growing beneath it.
