The Voynich Botanical Plants

Folio 4r, Alpine Saxifrage (Saxifraga cespitosa), is a species of edible plant found in Northern temperature zones. It has a taproot, and the leaves are opposite and evenly distributed along the trailing stems. At the beginning of each growing season the old leaves turn orange and die (McJannet C.L., Aiken S.G., Dallwitz M.J., Gillespie L.J. and. Consaul L.L.). The flowers are single and purple. The name, Saxifrage, comes from the Latin for rock-breaker because of its apparent ability to split rocks. As a result, it was prescribed as a herb for breaking up bladder and gallstones.
