Rhododendron lepidotum Wall. ex G. Don (Ericaceae) is one of the dominant species of the genus in the Himalayas, having a wide distributional range from Pakistan, India, Nepal, China and Bhutan to Myanmar. Throughout its distributional range the species experiences widely variable eco-climatic conditions and thus different morpho-forms are prevalent. A quick search reveals that about 12 names are available under this species complex, reflecting its variability in morphological characters. Presently, a study has been conducted to reassess its morphological variability among the different populations both in the field and through the examination of specimens at different Indian and foreign herbaria. Several important parameters, both vegetative and reproductive were identified and examined to test the faithfulness of these characters of diagnostic value. PCA and UPGMA analysis were also performed to confirm the findings. Relevant literatures were critically examined to understand the reliability of different names published under the species complex. Present study recognized three well defined 'morphoforms and has been compared for better understanding. Apparent reliability in diagnostic features of the presently recognized Form I is corroborative with R. salignum Hook.f. The status of the taxa Rhododendron lepidotum Wall. ex G. Don, R. salignum Hook.f., R. obovatum Hook. f., R. elaeagnoides Hook. f., R. lepidotum var. elaeagnoides (Hook. f.) Franch., R. sinolepidotum Balf..f., R. cremnastes Balf. f. & Farrer, R. lepidotum var. album H.H. Davidian, R. lepidotum var. minutiforme H.H. Davidian, R. lepidotum subsp. salignum (Hook. f.) Pradhan & Lachungpa and R. lepidotum subsp. obovatum (Hook. f.) Pradhan & Lachungpa are discussed and their morpho-plasticity are addressed. Only two names R. lepidotum Wall. ex G. Don subsp. lepidotum and R. lepidotum Wall. ex G. Don subsp. salignum (Hook. f.) are accepted. All other names are considered as synonyms under these two taxa as also advocated by some other previous authors.
