Distinguished by having small tubular flowers with the petals in line with the corolla tube. Leaves are oblong-obovate, round at the apex and erose-denticulate at the margin with the teeth terminating in hydathodes. Primula prenantha has a large distribution and is uniform in appearance except in SE Tibet where ssp. morsheadiana occurs. Subspecies morsheadiana has larger, campanulate flowers rather than the tubular flowers of subspecies prenantha. The capsule varies also. Taken in isolation, subspecies morsheadiana looks to be distinct but in SE Tibet intermediates between the two exist. Images of this subspecies are shown in the later half below. Primula microloma is a white flowered form collected once on the Salween-Irrawady divide and needs to be re-examined.
