Discovery and description of a new plant species from central VietNam

The new species is most similar to A. laoticum and A. vietnamicum but can be distinguished from the latter two by having a well-developed internode with leaf pairs separately arranged along stem, isophyllous or slightly anisophyllous leaves, an oblanceolate to spatulate lamina with attenuate base and lateral veins with 4 - 5 pairs prominent on abaxially, a terminal, solitary flower, an absent bract, narrowly ovate or broadly lanceolate, 8.5 - 10.5 × 2.8 - 4.2 mm petals, 6.5 - 7.5 mm long stamen with yellow anther, a 8.5 - 9.5 mm long, exerted style and a globose stigma. Information on ecology, phenology and preliminary conservation assessment of the proposed new species are provided.

The result was published on Nordic Journal of Botany2020: e02765doi: 10.1111/njb.02765
