Abstract
We propose the new species Dyckia pseudodelicata which is described and illustrated here, and provide data on its distribution and habitat. We compare the new species to the related Dyckia delicata and highlight their morphological differences. Morphological features that have been little explored in Dyckia taxonomy proved to be diagnostic in our analysis, such as the presence and morphology of trichomes on the petal margins and the position of ovules in relation to the longitudinal axis of the ovary and their disposition in the placenta.

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.
