1.4. Eugenia angustissima O.Berg (1859: 569) .

= Aulomyrcia stenophylla O. Berg (1861: 654) , syn. nov. Type:— PARAGUAY. Unknown date, Rengger s.n. (holotype P [P00161080] [image!]).

The protologue of Aulomyrcia stenophylla compares it to Myrcia linearifolia Cambessèdes (1832 –1833: 334) (M. sect. Myrcia ), M. pinifolia Cambessèdes (1832 –1833: 333) (M. sect. Aulomyrcia ) and M. laricina (O. Berg 1857 –1859: 61) Burret ex Luetzelburg (1906: 201) (M. sect. Aguava), certainly due to the narrow leaves that all these species possess. Also, they share a low growing habit (except by M. laricina , which can be arborescent; Lima 2017) and woody rootstock, features that are not uncommon in Myrtaceae from dry or seasonal areas such as the Paraguayan vegetation. However, these features are also found in species of other genera, as is the case of Eugenia angustissima O. Berg (1857 –1859: 569), which is relatively common in seasonally dry vegetation. The type collection of A. stenophylla shows many features in common with E. angustissima , for instance the clustered and narrow leaves, solitary flowers and similar bracteoles. For this reason, A. stenophylla is considered a synonym of E. angustissima .

The cited specimen is considered the holotype as it is the only one annotated as Aulomyrcia stenophylla by Berg.
