Elatostema xanthotrichum W.T. Wang & Y.G. Wei sp. nova and E. bamaense W.T. Wang & Y.G. Wei sp. nova (Urticaceae) from Guangxi Province, China, are described and illustrated. Elatostema xanthotrichum most closely resembles E. rupestre but differs in its appressed, yellow-pubescent and 1-branched stems, auriculate leaf base at the broad side of the leaf, 5-paired secondary nerves, 6–8 staminate bracts, and obovate to spatulate-linear staminate bracteoles, which are ciliolate at apex. Elatostema bamaense most closely resembles E. nanchuanense but differs in its glabrous stems and leaves, narrowly lanceolate and non-corniculate pistillate bracts, and verruculose, non-ribbed achenes.
