KHASIA MTS., alt. 4-6000 ft., Wallich, &c.—DISTRIB. Java.

Leaves thin, nerves reticulate, petiole broad. Scape 12-18 in., stout, quite erect ; flowers in 2-4 distant whorls, pedicels subequal ; lower bracts sometimes foliaceous. Calyx 1/5 in. long, 5-ribbed. Corolla-tube 1/2 in. Capsule quite glabrous, 1/2 in. diam., not exserted. Seeds rather large, 1/25 in. diam., coarsely papillose.—I can see no difference between the Khasian and Javan plants. The Japanese P. japonica, A. Gray, differs chiefly in the purple flowers. I have not found any specimens of this in Wallich’s Herbarium.

Primula prolifera East Himalayan plant from UCBG-GS06022021-1
Primula prolifera Wall.
An Interesting species from Eastern Himalayas, characterized by yellow flowers in successive whorls, whereas in most species of the genus flowers are in terminal umbel on a long scape.
Photographed from University of California Botanical Garden, 22-4-2019.

It looks different as per images and references at Lysimachia prolifera
Also I could not find Primula proliferaWall. in Catalogue of Life and POWO. They mention Lysimachia prolifera Klatt only.

Lysimachia prolifera and Primula prolifera are two very different plants and there is no reason to confuse them
