INTRODUCTION Annonaceae is one of the largest family of Magnoliales which includes 108 genera (POWO 2025) and c. 2400 taxa (Guo etal. 2017). Whilecheckingtype specimens of the family Annonaceaefromthe Central National Herbarium (CAL) for thetreatmentof the Annonaceae family in Indiainthe Flora of India project, wenotedthat thefollowingnamesneedformaltypification. Aftercarefulinspection, wechoosea lectotype for Melodorum macranthum Kurz (basionym of Goniothalamus macranthus) and a second-step lectotype for Mezzettia curtisii King.The herbarium acronyms follow Index Herbariorum (https://sweetgum.nybg.org/science/ih/).

Kurz s.n.; lectotype: CAL[CAL0000004545!], here designated (Fig. 1); isolectotype: CAL (acc. no. 13892!). typificAtion remArks Willhelm Sulpiz Kurz (1834-1878), Curator of the Herbarium, Royal Botanical Gardens, Calcutta, conducted an expedition to the Andaman Islands from April to July 1866 to collect plant specimens for the preparation of the ‘Flora of the Andaman Islands’. Kurz had first suggested the name Unona macrantha Kurz (nom. nud.) in his ‘Report on the Forests of the Andaman Islands’ (appendix B. I) dated 1867 (report could not be traced) as cited by King (1893) and Merrill (1919). Kurz (1870) again introduced another invalid name Pyramidanthe macrantha Kurz (nom. nud.) in his report, titled ‘Report on the Vegetation of the Andaman Islands’ Finally, he validly published the name Melodorum macranthum Kurz from his collection in ‘Andamans’ in Journal of the Asiatic Society of Bengal, Part I (Kurz 1872: 291). Initially, only one specimen (CAL0000004545) was found in the type collections at CAL, which Turner (2018) treated as the holotype, citing it as ‘India, Andaman Islands, South Andaman, S.Kurz s.n. (holotype CAL [CAL0000004545])’. However, an annotation by Debika Das (06.10.1966), indicates that this specimen was also considered a lectotype of Goniothalamus macranthus (Kurz) Boerl., although it was not validly published. A further search in the general collections at CAL revealed a duplicate specimen (accession number 13892) collected by S. Kurz from South Andaman, with an original label bearing Kurz’s handwriting with the name ‘Unona macrantha Kurz’ and the name ‘Melodorum macranthum Kurz’ on the sheet. According to the protologue, this specimen also qualifies as original material. Therefore, both specimens at CAL (CAL0000004545and CAL acc. no. 13892) are considered syntypes, necessitating lectotypification. In accordance with Art. 9.12 of ICN (Turland etal. 2018), the well-preserved flowering specimen CAL0000004545 (Fig. 1) is hereby designated as the lectotype of M. macranthum Kurz.

Mezzettia curtisii King (Fig. 2) Journal of the Asiatic Society of Bengal, Part II (Natural History& c.) 61: 129 (King 1892). t ype specimens . — Malaysia • Penang, Government Hill; 1200ft. alt.; III.1890; C. Curtis 2266; lectotype: CAL[CAL0000025019!], first-step lectotype designated by Van der Heijden& Kessler, Blumea 35: 223 (Van der Heijden& Kessler 1990); second-step lectotype here designated (Fig. 2); isolectotypes: BM[BM000546402, digital image!, BM000546403, digital image!]; CAL[CAL0000025017!]; K[K000574883, digital image!, K000574884, digital image!, K000574885, digital image!], SING. typificAtion remArks According to POWO (2025), Mezzettia curtisii King is a heterotypic synonym of M. herveyeana Oliv. (Hooker 1887). George King validly published M. curtisii (King 1892: 129) based on Curtis’s collections and indicated the type as ‘Penang, on Government Hill at 1200 feet; Curtis, No. 2266.’ Van der Heijden& Kessler (1990) in their revision of the genus Mezzettia, expected the holotype to be housed at CAL and cited type as ‘Curtis 2266, Malaysia, Penang, Government hill, 360 m alt., March 1890 (holo-, CAL, n.v.; iso-, BM, K).’ Turner (2011) also considered CAL specimen as holotype. Later, Turner (2015) felt that the CAL specimen is a syntype rather than holotype and he chose one syntype at K and designated it as ‘Lectotype: Malaysia, Peninsula Malaysia, Penang, Government Hill, Mar 1890, C. Curtis 2266 (lecto-, K (barcode no. K000574885); isolecto-, BM [×2], CAL [×2] (barcodes no. CAL0000025017 and CAL0000025019), K[×2] (barcodes no. K000574883. K000574884), SING.’ It is quite sure that Turner (2015) overlooked the earlier type designation by Van der Heijden& Kessler (1990) and he changed his decision in his next publication (Turner 2018) where he considered the type designation by Van der Heijden& Kessler (1990) as effective lectotypification and cited ‘TYPE: Malay Peninsula, Penang, Government Hill, March 1890, C.

Therefore, the lectotypification of Turner (2015) is ‘Superfluous’. Van der Heijden& Kessler did not see the type material at CAL and did not annotate any specimen as a lectotype. In CAL, we found two original materials (CAL0000025017 and CAL0000025019) bearing the same data with original label that was mentioned by Van der Heijden& Kessler (1990) in their publication. According to Art. 9.17 of the ICN (Turland etal. 2018), it was found that a second-step lectotypification is required. After considering Van der Heijden& Kessler (1990) as first-step lectotypification, the specimen CAL0000025019 (Fig. 2) is designated here as the second-step lectotype of M.curtisii King. While searching for images of original materials of M. curtisii King on the Global Plants website, we found two type specimens K000574884 and K000574885, which perfectly matches with L.0197402 and L.0197403, respectively (https:// plants.jstor.org/search?filter=name&so=ps_group_by_genus_sp ecies+asc&Query=Mezzettia+curtisii). Upon close examination of the images, we noticed a scale with the printed text ‘Royal Botanic Garden – Kew’ and ‘ILFORD, CIBACROME COPY’ on both images of L. Additionally, type annotations are present on both images. The images at L are colour copies of the original specimens deposited at K. Acknowledgements We are most grateful to Dr A.A.
