Sentence Correction (SC) | Re: Unlike most gynodioecious plants, the male and female Catasetum orchid

So just to understand Parallelism better, I can't use "adjectives" in the comparisons,if the adjective is only associates with one entity and not the other?

E.g. Can I not say "Unlike Reynolds, blue Trimax costs more!"?

Instead, something like this might work? - "Unlike black Reynolds, blue Trimax costsmore!"
