What do you make of this plant? (f89v)

[MarcoP]

Dragon Arum / Dracunculus Vulgaris was often represented with a zoomorphic root (attached BNF It. 1108). The wihte spathe is greenish when unfolding and can have irregular, almost jagged, borders (see picture). If the Voynich illustration corresponds to dracunculus, the spike is missing, but this is the case also in the BNF illustration. I don't think I know of examples with no leaves, but the "pharma" section seems to present "abbreviated" illustrations of plants: one more of its many peculiarities.
