This can be isolated to,

{{Herbarium of Baltimore Woods table
|genus=Humulus
|family=Cannabaceae
}}
|{{Herbarium of Baltimore Woods specimen
|species-name=Humulus lupulus
|author-name=L.
|var-name=lupulus<ref>Could possibly be ''Humulus lupulus'' var. ''lupuloides'' (native northeastern American hops), but that's less likely.</ref>
|common-name=European hops, common hop
|nativity=Introduced from Eurasia
|ntz=Cultivated, naturalized
|nwi=FACU
|fny-link=Rhamnaceae_…_Urticaceae#Humulus
|image-name=Humulus lupulus var. lupulus BW-1979-1001-0438.jpg
|orig-species=Humulus lupulus
|orig-author=L.
|orig-common=Common hop
|orig-habitat=Openings
|orig-date=Oct. 1, 1979
}}
|}

Expanding the template, you get to the problematic content model violation of a-in-a, from the reference in the wikilink content,

[[b:Flora_of_New_York/Rhamnaceae_…_Urticaceae#Humulus|'''''lupulus<ref>Could possibly be ''Humulus lupulus'' var. ''lupuloides'' (native northeastern American hops), but that's less likely.</ref>''''']]

Maybe we'll want to lint those away?

Noting that I saw a couple of instances of this error today.

Saw a handful of these on commonswiki today, the stacktrace has shifted around a bit, pasting here in case it's helpful.
