It grows on hill slopes composed of sandstone at +565 m +elevation, under the canopy of lower primary evergreen broad-leaved forests. + + + + +Etymology +: The epithet ‘ + +lophura + +’ refers to the resemblance of the blue iridescent sheen leaves, which resemble the metallica blue feather of +Lophura edwardsi +. + + + + +Conservation: + +Begonia lophura + +was collected along the roadside from protection forest in Tra Bui Commune where no signs of major anthropogenic disturbance have been noticed. Therefore, the species is preliminarily assigned to Vulnerable (VUD2) category according to The Guidelines for Using The IUCN Red List Categories and Criteria ( +IUCN 2019 +). + + + + +Notes: + +Begonia lophura + +resembles + +B. pavonina +Ridley (1909: 22) + +, while the latter is a handsome species from Cameron Highlands in Peninsular +Malaysia +and also belongs to sect. +Platycentrum +. The two species bear superficial similarities by having ovate leaves that have upper surfaces which produce an indigo blue iridescence when the light is reflected at certain angles, 4-tepaled staminate flower and 5-tepaled pistillate flower. However, + +B. lophura + +is distinct from + +B. pavonina + +( +Fig. 7 +) in its leaves that are widely ovate (vs. ovate) and red hirsute on abaxial surface (vs. glabrous), bracts persistent (vs. caducous), tepals hirsute in both of staminate and pistillate flowers (vs. glabrous), capsule scabrous (vs. glabrous) and abaxial wing strongly swollen (vs. thin, not swollen). The new species is also closely similar to + +B. menglianensis +Y.Y. +Qian (2001:461) + +in widely ovate, velvety foliage and inflorescence structure, but differs in its adaxial lamina surface with blue iridescence (vs. absence of blue iridescence), ovary hirsute (vs. fusco-villose) and abaxial wing strongly swollen (vs. thin, not swollen).
