Type (lectotype designated here):— CHINA. W-Yünnan: In schattigen Gebüschen und Mischwäldern, 3000 m, VIII. 1917, Forrest 15838 (barcode W0131824 !, isolectotype: E00010637!). [Image available at https://w.jacq. org/ W0131824 ] .

Note:—In the protologue, Handel-Mazzetti (1933) cited two collections from China, in which “ W.Y.: In schattigen Gebüschen und Mischwäldern, 3000 m, VIII. 1917 (Forrest 15838)” was designated as the type, but did not indicate the herbarium where the type specimen preserved. According to Stafleu and Cowan (1979), Handel-Mazzetti’s type material was mainly deposited in W and WU. We traced 5 duplicate specimens, deposited in A, E, K, P and W. The sheets in A (barcode 00040707) and P (barcode 00755313) was dated Jan. 1917, while the sheet in K (barcode 000737911) dated 1917-1919 was not seen by Handel-Mazzetti and also not mentioned in the protologue, hence these sheets cannot be select as lecotype. We located original material at E (barcode 00010637) and W (barcode 0131824), both of them matching the locality and date mentioned above. We designate the blooming specimen of “ Forrest 15838 ” at W (barcode 0131824), where Handel-Mazzetti worked as the lectotype. The selected sheet is a complete and well-preserved specimen that displays all the morphological diagnostic traits in agreement with the protologue.
