The Voynich Botanical Plants

Folio 96v, Black Bryony (Tamus communis), is an herbaceous vine native to Europe and Northwestern Africa. The heart-shaped, pointed leaves are spirally arranged along the twining stem. The vine has separate male and female plants, both with small, greenish-yellow flowers, the latter being succeeded by red berries when ripe. It is very similar to a yam with a large fleshy black tuberous root. The vine, including the root, is poisonous. Juice from the root has been used with great care as a diuretic. The berries act as an emetic when eaten.
