Original diagnosis/description

Penultimate branches opposite; on ultimate branches scale leaves arranged decussately or almost decussately, on wider branches helically in a very low spiral; leaf margin scarious; abaxial leaf surface rugose and bearing stomatal apparatuses arranged in longitudinal rows separated by rows of elongate ordinary epidermal cells; stomatal apparatuses monocyclic, with four to six non-papillate subsidiary cells; stomatal apertures mainly obliquely oriented; ordinary epidermal cells non-papillate; hypodermal bundles of sclerenchyma heavily lignified and with sinuous patterns around the uppermost portions of the substomatal chamber; tracheids of the primary xylem with scalariform thickenings.

Etymology

The specific epithet is after Dr. Ellen "Ellie" Sattler, the fictional character of the Jurassic Park novel and film portrayed by Laura Dern, who contributed to popularizing the role and importance of both palaeobotanists and women for science in general.
