Description

13. Casearia ulmifolia Vahl ex Vent., Choix Pl.: sub tab. 46. 1808.

Lectotypus (first step designated by Sleumer, 1980: 324; second step designated here): TRINIDAD: 1778, Ryan 20 (C [C 10012565] image seen; isolecto-: BM [BM000624343] image seen, BR [BR0000005104826] image seen, C [C 10012566, C 10012567, C 10012568, C 10012569, C 10012570, C 10012571] images seen, G [G00364133]!, L [L0010781] image seen, P-JU n° 16215 [P00678826]!).

Notes. – Ventenat validated Vahl’s name by publishing a few comparative leaf characters: “[bords de feuille] finement dentés en scie”. Sleumer (1980: 324) correctly considered the type as being held at C. His implicit lectotypification needs a second step designation as seven sheets exist at C. In their revision of the Casearia ulmifolia complex, Marquete & Mansano (2012: 201) failed to properly designate a single sheet at C as the lectotype. We designate the most complete sheet in C as the lectotype. Several isolectotypes are known, among them one in Ventenat’s herbarium. We are not in agreement with previous authors (Sleumer, 1980; Marquete & Mansano, 2012) and do not consider the collection in G-DC [G00476917] as elements of original material.
