Abstract
SynopsisThree cupules of Eurystoma angulare are described; they bear one, six, and ten attached ovules respectively. The cupules are built up of several terete branches which dichotomise in successive planes at right angles. Where an ovule is borne a small number of dichotomies are adnate basally so forming an ovuliferous syntelome.
