Primula occlusa is a very small species found in SE Tibet and Arunachal Pradesh. A small plant (2.5-5cm). Leaves flabelliform or sub-orbicular, rounded at the apex, serrate-dentate in the upper half and covered above and on the veins below with short hairs giving a scabrid appearance. Leaves are genarlly efarinose but may sometimes have small patches of farina. Scape is farinose at the apex, bracts are leafy. Flowers are purple with a white eye and a pompon of white hairs in the throat. This species is very close to P. primulina and was identified initially as a variety of it, but it differs in the orbicular leaf shape, tendency to single flowers and broader bracts.
