Notes — Focke (1891) described R. lasiostylus on the basis of specimens collected on March 1889 by Augustine Henry from Patung [Badong], Hupeh [ Hubei] Province , central China. We found specimens in GH *, K * and BM * that can be considered original material. The single herbarium sheet in BM * (barcodes BM000622276 , BM000622277 ) has specimens with two differ- ent field numbers (upper 5788; lower 5788 A). The specimen at K * (barcode K000737817 ) has an original annotation ‘typica et tomentosa’ by Focke himself and is selected here as the lectotype ( Fig. 2a View Fig ) . The other four specimens, no. 0000011654 and 0000011657 ( CAL); no. 0040643 ( GH *, all three twigs) and no. BM000622277 ( BM *) are considered as isolectotypes .
