Nomenclatural notes.

While describing Jasminum alongense , Gagnepain (1933a) referred to the specimens collected by H. Lecomte and A. Finet from Tonkin (presently in North Vietnam) Hongay (Hon Gai/ present-day Ha Long Bay). Several duplicates of the same were submitted at P. However, some of them were sent to K, evident from the label on these collections. We could locate two specimens at P (P00087775 and P00087776), and four at K. All K specimens are originally from P, pasted on new sheets and without any K barcode. Two of them, however, possess the preexisting P barcodes P00087775 and P00087776 but the remaining two do not have any). Specimens P00087775 and P00087776 at P are annotated as holotype and isotype respectively, however, they were never published effectively. A thorough survey of literature and virtual herbaria revealed that earlier workers ( Ho 2000; Tran 2003) did not designate a lectotype for the name J. alongense . Therefore, following Art. 9.6 of the Shenzhen Code ( Turland et al. 2018), P00087775 at P is being designated here as the lectotype of J. alongense . This specimen not only best matches with the original description but also possesses the reproductive parts and original drawing of the dissected floral parts.
