12. * Eugenia calycorectoides O.Berg, Linnaea 29: 236 (1858)

EOO: 16,297.727 km ². AOO: 28 km ². Evaluation of IUCN: Vulnerable.

Eugenia calycorectoides is found only in Mexico in the states of San Luis Potosí, Veracruz, and Morelos, and the species is known only for 7 records, in two types of biomes, being the Humid Tropical Forest and the Humid Montane Forest. The species can be found from 300 to 1,300 m elev. The estimated extent of occurrence ( EOO) falls within the threshold of Vulnerable category under criterion B, whilst the estimated area of occupancy ( AOO) falls within the thresholds of the Endangered category. Eugenia calycorectoides is known to occur within the biological protection area “Parque Nacional Cañón de Rio Blanco”, located in Veracruz ( DOF 1938). Therefore, there are only between 5 to 6 known locations and all of them have ongoing threats. A continuing decline of its habitat is inferred due to human activities (crop production, recurrent timber extraction in the region, urban development; CONABIO 2018). Considering that still there are remaining habitat available and scarce collection efforts within its entire range, a precautionary approach is taken here to classify Eugenia calycorectoides as Vulnerable ( VU) as it meets the criteria B 1ab (iii)+ B 2ab(iii).
