The drawing on fol. 43r of the Voynich manuscript may be composed to represent Noah's ark as we see it in medieval pictures - boat with a house. The ebony tree is one of the main suspects for gopher wood - the material of Noah's ark. The VMs drawing may be meant for ebony tree forest judging by the blue tint of the stems/trunks. Some ebony trees have edible fruits used in traditional medicine - the date-plum (Persimmon, Diospyros lotus) for example. Whatever the plant on fol. 43r is - it may be connected somehow to the story of Noah's ark.
