Resembling or having the characteristics of an anther in appearance or structure.
From Greek 'anthera' (anther) + '-oid' (suffix meaning resembling). The '-oid' suffix became standard in scientific terminology in the 19th century for describing similar structures.
The '-oid' suffix appears in 'humanoid' (human-like) and 'spheroid' (sphere-like), so 'antheroid' is a botanist's way of saying 'looks like an anther, acts like an anther, but we're not 100% sure it actually is one.'
