The Voynich Botanical Plants

Folio 18r, Aster (Aster alpinus), is native to both Eurasia and North America. The name is derived from the Greek word meaning star. This perennial plant is 1 to 3 feet tall, branching occasionally. The alternate leaves are lanceolate and become smaller as they ascend up the stem. The flower has numerous small disk florets that are surrounded by about 8 to 12 ray florets. The base of mature plants can develop short rhizomes that facilitate the formation of colonies.
