"What’s in a name?

I learned these two native species as “Short-leaved” and “Long-leaved” as an easy way to distinguish them: M. aquifolium has many fewer leaflets per leaf (5-9), while M. nervosa has 9-19 leaflets per leaf. Additional features reflected in some common names refer to: M. nervosa having duller, less shiny leaves than M. aquifolium; and M. aquifolium having much more pronounced holly-like foliage (“aquifolium” specifically translates to “sharp-leaved”). And if youreally want to get into the weeds on this, you can look at the veins on the underside of the leaves: “nervosa” refers to the fan-like veins vs. the one central vein on the M. aquifolium. Whew!"
