Myrcia stenocymbia Diels 1906

3.33. Myrcia stenocymbia Diels (1906: 596). Type:— PERU. Depto. Junin, Prov. Tarma, in valle Chanchamayo pr. La Merced in silvis apertis, 1000 m, December 1902, Weberbauer 1884 (syntype B [destroyed]). The protologues of these five species describe features such as a pilose floral disk (Aulomyrcia platyclada, M. heliandina, M. stenocymbia) and cylindrical fruits (M. cristalensis), which would allow their placement in Myrcia sect. Myrcia. Furthermore, they are compared in the protologues with species belonging to this section: Myrcia cristalensis and M. heliandina are compared with synonyms of M. splendens (Swartz 1788: 79) De Candolle (1828: 244), and M. atramentifera is compared with M. eximia De Candolle (1828: 248). Myrcia sprengeliana was described by Berg in Myrcia, whose circumscription in his sense is similar to Myrcia sect. Myrcia, though no typical feature is described in the protologue. However, the types of these species were not found, preventing conclusions to be drawn regarding the validity of the names.
