Mare's tail should be no problem as it's a flowering plant.
However Horse tail is very different.

So what do you mean by Mare's tail? I always thought mare's tail
referred to the Equisetums that are grown ornamentally, which are no
more a flowering plant than are the horsetails. But Fitter uses
marestail for Hippurus vulgaris, which is a flowering plant

Ancients did indeed believe that Mare's and Horse tail were related.
The mare's tail was thought to be a feminine form. Mare's tail has genuine
flowers with single stamens, followed by nuts. Not even remotely related to
Horse tail. Hippuridaceae c/f Equisetum.

They're a lot further away than merely different families. Marestail
(Hippurus) is a flowering plant along with nearly everything else we
grow, including conifers and grasses. Horsetails (Equisetum) are
spore-bearing plants like ferns.
