Primula boothii is found over a large area from Nepal, through Sikkim, Bhutan, SE Tibet and Assam. This species and related species in the Petiolares Section have been misunderstood and misnamed. They are variable and can hybridize adding to the confusion. P. boothii is distinguised by having efarinous leaves usually with a red mid-rib stalk and a calyx with keeled sepals giving a twisted appearance. The subspecies autumnalis is autumn flowering and from the Ghorapani area of Nepal. The subspecies repens is stoloniferous and from a small area south of Annapurna. A white form in horticulture is called var. alba. The Flora of China considers P. boothii to be a synonym for P. bracteosa.
