Traveler's Joy (Clematis Vitalba) is my choice for plant Id for fol. 27v of the Voynich Manuscript.
The leaves and the fruits match the drawing and the root shape has some similarities to rope making tools. According to Johnson, Magnus, 2001, The Genus Clematis book the Traveler's Joy was used in Switzerland for rope making since the Stone Age. It is still reflected in the common names of the plant in Bavaria and Austria.
