This form of “R. purdomii-Maculifera“/R. oreodoxa var. shensiense now called R. henanense ssp. lingbaoense have ciliate margins and the midrib underneath and the stems have long bristles (as a young plant). I have seen these plants marked R. purdomii in Gotheborg and in Genova Botanical Gardens. To me it looks like a very close relationships to R. pachytricum. Also K. Cox could see the relationship to R. marculiferum (Encyclopedia p 58).
What about to call it “R. taibeiense” or R. pachytricum ssp. / var. taibeiense ** 1998.
** Now a Laponica found in this area have got this name 2007. R. henanense ssp. lingbaoense is described in 1983 by W.P. Fang.
