Greek pachys ‘thick, massive’ + Cereus, the name of a genus of columnar cacti and a designation for columnar cacti in general. It seems obvious that the name refers to the thick stems, but Berger does not mention this characteristic. He does state that the species of this genus are “gigantic”, so the name most likely refers to the overall size.

“Botanical Latin is essentially a written language, but the scientific names of plants often occur in speech. How they are pronounced really matters little provided they sound pleasant and are understood by all concerned.”
