๐. ๐ง๐ข๐ญ๐ค๐ข๐ต๐ช๐ง๐ฐ๐ญ๐ช๐ข was discovered in a secondary forest on a coastal mountain in Barangay Mabua, Surigao City, Surigao del Norte, Philippines. This species differs from all other Philippine members of section ๐๐ข๐ณ๐บ๐ข๐ฏ๐ฅ๐ณ๐ข primarily in its falcate leaf blades, from which the specific epithet โ๐ง๐ข๐ญ๐ค๐ข๐ต๐ช๐ง๐ฐ๐ญ๐ช๐ขโ is derived. Unfortunately, given its restriction to a single known locality, small population of approximately 30 mature individuals, and constant exposure to anthropogenic threats, we designate ๐. ๐ง๐ข๐ญ๐ค๐ข๐ต๐ช๐ง๐ฐ๐ญ๐ช๐ข as ๐๐ซ๐ข๐ญ๐ข๐๐๐ฅ๐ฅ๐ฒ ๐๐ง๐๐๐ง๐ ๐๐ซ๐๐ (๐๐).
This discovery increases the number of Begonia species recorded in Surigao del Norte Province to eight and represents the fourth member of section Baryandra documented from the province. A key to all species in Surigao del Norte province is provided in the paper.
Congratulations to our MS Biology (Plant Biology) student, Ken Bien Mar Caballes and our faculty member, Noe Shaw Mendez. Congratulations also to their co-authors from the Philippine Taxonomic Initiative (PTI), Yu Pin and Maverick N. Tamayo! ๐
