Primula tenella was first discovered in the Chumbi valley by King's collector, then later in nearby Bhutan by Cooper, Gould, and Ludlow & Sherriff. In 2004, Richards described P. rebeccae, comparing it to the much larger species P. caveana which also grows in the same region, but no comparison was made with P. tenella. The type location for P. rebeccae is Jangothang, Bhutan, less than 40kms away from Chumbi, and several collections of P. tenella have been made in this area. There is no difference between P. rebeccae and P. tenella from the evidence available. See blog post: "Primula rebeccae A.J. Richards a synonym for Primula tenella King".
Primula flagellaris was discovered in the Zemu Valley, Sikkim by Smith & Cave and then later in Bhutan by Ludlow & Sherriff. It has been previously lumped with P. tenella as a variation
as the differences are minor. The last image is of P. rebeccae given in the original description. If you have images of P. tenella from Chumbi, please contact the webmaster. 如果你有这个物种的图像,请与网站管理员联系。
