Etymology: The specific epithet “pseudodelicata” refers to the vegetative similarity between the new species and D. delicata. The new species was not flowering when first collected and was believed to be D. delicata. However, significant morphological differences found after checking its inflorescences revealed it to be a new species, which we decided to call “false” D. delicata.
