( Fig. 27E )

Mitt. Inst. Allg. Bot. Hamburg 20: 84 (Rohwer 1986). — Endlicheria grandis Mez, Jahrb. Königl. Bot. Gart. Berlin 5: 124 ( Mez 1889). — Nectandra grandis (Mez) Kosterm., Meded. Bot. Mus. Herb. Rijks Univ. Utrecht 25: 17 (Kostermans 1936).

NOTES. — The indications given by Mez (1889: 125) on the (fruiting) material he studied are: “Hab. in Guyana gallica ad fl. Maroni: Mélinon. (V. s. in herb. Berol. et Paris .)” There is only one Mélinon specimen of R. grandis at B, with a label in Mez’ hand reading: “ Endlicheria ? grandis Mez nov. spec., det. Carl Mez”; its original label bears the date 1865 and does not mention the Maroni River, or any other location, within French Guiana. Among the eight Mélinon specimen of R. grandis at P (all in fruit), only three bear the same identification label by Mez:P00745439, with an original label reading “Guyane française (Maroni). M. Mélinon 1862”; P00745443, with a label “Herbier de la Guyane française. 1865 – Mélinon”; and P00078423, labelled “Guyane française – M. Mélinon 1863”. The five other specimens (P00745440, P00745441, P00745442, P00745444, P00745445) are all dated 1863, and only one of them (P00745441) has a label mentioning the Maroni. Another Mélinon specimen at NY (00355136) is also dated 1863 and the only geographical indication is “Guyane fse”.

Only the four specimens annotated by Mez can be considered to be indisputably part of the original material. However, they could represent separate collections made in 1862, 1863 and 1864, therefore they must be treated as syntypes.

Madriñán (2004: 85) designated a lectotype as: “ French Guiana. Fleuve Maroni [St Laurent?], 1863 (fr), Mélinon 1863 [1865 in B] (lectotype, here designated: B; isolectotypes: NY, P”. This lectotypification is correct in that it unambiguously refers to a single specimen at B, that is part of the original material. However, the date, place and collection number given for this specimen are incorrect, leading to syntypes (at P and NY) being mistaken for isolectotypes. The correct citation for the lectotype is given below.
