Abstract: We corrected the stamen number(a key identification feature) of Rhododendron shanii from 10 to 12-15 through surveying the stamen number of R.shanii from five populations(containing typical locality), investigating plenty of specimens and interviewing the man who collected the type specimens. We also compared the morphology of R.shanii with R.fortunei which were planted in the same location, the result showed that there were many differences between the morphology of these two species, proving that R.shanii is an independent ‘good species’.

Key words: endangered plant, Rhododendron shanii Fang, stamen number, Rhododendron
