Nasir & Meijer 8854 is also present in RAW. But this specimen is a mixture of Gentianodes eumarginata Omer and Gentianodes nasirii Omer et al. However, the annotations of the two la bels also differ in several respects i.e. altitude, habitat and flower colour.

Allied to Gentianodes eumarginata Omer but differs from it in h aving unequal calyx lobes, biennial-perennial(?) habit, cauline leaves provided in between by smaller leaves, corolla slightly swollen in the middle, filaments inserted slightly below the middle and anthers versatile.
