5.2.4. Myrcia ekmaniana (Urb.) M.F.Santos , comb. nov. Plinia ekmaniana Urban (1927: 23) . Type:— HAITI. Massif du Nord, St. Louis , Morne Baron, top of the mountain, 18 August 1925, Ekman 4653 (lectotype S [S 03-2108] [image!], designated here; isolectotypes K [image!], NY [image!], S [S 07-9163] [image!], US [two sheets] [image!]).

Plinia ekmaniana is transferred to Myrcia due to its inflorescence structure (a “panicle” with terminal dichasia), free calyx lobes and two ovules per locule. In the protologue, Urban (1927) compared Plinia ekmaniana with two species of Myrcia : Myrcia manacalensis Urb. (1923: 85) and Myrcia guildingiana ( Grisebach 1864: 242) Krug. & Urban (in Urban 1894 –1895: 57) (at that time treated as Plinia guildingiana (Griseb.) Urban [1927: 23] ). Myrcia ekmaniana also resembles Myrcia abbotiana ( Urban 1924: 341) Alain ( Liogier 1971: 138) . Features such as the prolonged hypanthium, the two-locular ovary and glabrous receptacle, together with vegetative similarity with Myrcia abbotiana , place the species in M. sect. Aulomyrcia .
